Used ChatGPT to Prepare for My Exam

I uploaded a PDF of a book I need to study for an exam and discussed it with ChatGPT to develop a study methodology. ChatGPT divided the book into chapters, chapters into modules, and modules into parts. At the beginning of each study session, ChatGPT gives me a 10-question quiz covering all the topics I studied through the previous day. It marks my answers according to our methodology, then provides notes for the next part of the module. After I review the notes, I take a quiz based on that material. At the end of each study session, ChatGPT gives me a quiz covering all the topics studied that day. It calculates the quiz-wise marks percentage, the overall percentage for the day, and a comparison with previous days. Questions I answer incorrectly are added to the Error Notes. After I complete a chapter, ChatGPT provides notes for that chapter in a downloadable format. Step-by-step: 1. I uploaded the PDF of the book I need to study for the exam. 2. I discussed the study process with ChatGPT and developed a methodology. 3. ChatGPT divided the book into chapters, chapters into modules, and modules into parts. 4. At the start of each study session, I took a 10-question quiz covering all topics studied through the previous day. 5. ChatGPT marked my answers according to our methodology and provided notes for the next part of the module. 6. I reviewed the notes and took a quiz related to that material. 7. At the end of the study session, I took a quiz covering all topics studied that day. 8. ChatGPT calculated the quiz-wise marks percentage, the overall percentage for the day, and a comparison with previous days. 9. ChatGPT added the questions I answered incorrectly to the Error Notes. 10. After I completed a chapter, ChatGPT provided notes for it in a downloadable format.

Use ChatGPT as a Game Master for Two-Player Tabletop RPGs

I’m retired and in my early 70s. I never got into RPGs growing up, but I decided to try a tabletop RPG with my wife. The game I purchased included a rulebook and a PDF of the book. I wanted my wife and me to play as the player characters without either of us having to be the game master, so I tested whether AI could take on that role. I used ChatGPT to parse the PDF and walk us through the process. It helped us create our characters, Heisenberg and Felicity, and then started the game as the game master. We’ve only just started, but it seems like this is going to work well. The AI can keep secrets to itself, roll the dice when needed, and guide us through the adventure. Step-by-step: 1. I purchased a tabletop RPG that included a rulebook and a PDF of the book. 2. I used ChatGPT to parse the PDF and walk us through the process. 3. ChatGPT helped my wife and me create our player characters, Heisenberg and Felicity. 4. We had ChatGPT start the game as the game master so neither of us had to fill that role. 5. We began playing while ChatGPT kept secrets to itself, rolled the dice when needed, and guided us through the adventure.

Human-Directed AI Music Workflow From Idea to Release

I built a repeatable, human-directed AI workflow for turning an original emotion, memory, or story into a finished WazWorld song, complete with cover artwork and release content. It addresses one of the biggest problems with AI music: a simple prompt can produce something technically impressive but generic, overproduced, or disconnected from the creator’s real intention. The workflow begins with a human trigger—an experience, relationship, place, mood, or musical idea that I genuinely want to express. WazWorld generally moves between dark alternative/electronic music and California coastal country-rock. Step-by-step: 1. I create a detailed artistic brief describing the song’s emotional core, story, genre, energy, vocal character, instrumentation, arrangement, dynamics, and intended listener experience. 2. I work with ChatGPT to develop and challenge the concept, write and rewrite lyrics, remove clichés, and design the full arrangement. This includes the intro, verses, choruses, instrumental passages, transitions, musical peaks, and outro. ChatGPT also helps translate my direction into precise production language and exclusions that Suno can understand. 3. I generate versions in Suno, treating each result as a demo rather than a finished song. I evaluate the vocal delivery, lyrics, bass, guitars, synths, drums, tempo, arrangement, and emotional impact. Then I make targeted prompt changes and generate new versions. A song may go through dozens of iterations before it sounds the way I originally heard it in my head. 4. After selecting the final music, I use ChatGPT and AI image generation to develop cover artwork that matches the song’s emotional identity. I adapt the artwork for streaming, YouTube, Instagram, Stories, and Shorts, then create the metadata, descriptions, captions, and promotional material needed for release. 5. I distribute the finished music through services such as DistroKid and publish it across streaming and social platforms. The final result is not a one-click AI song. AI provides creative and production tools, but I direct every major decision—from the original emotion and lyrics to the arrangement, instrumentation, vocals, artwork, and release strategy. Someone can recreate this workflow by starting with a clear human idea, documenting the desired sound, generating multiple versions, evaluating each one like a producer, and iterating until the finished work communicates the original intention.

A simple, free online tool for understanding home power usage and costs

I used the OpenAI Codex app to develop an idea I had while talking with my wife about power companies raising their prices during periods of high demand. We recently paid up to 90¢ per kW/h, which is insane, but when the kids hear “90¢,” they think it’s nothing. They don’t understand power pricing—or even what a kilowatt-hour is. https://kilowhat.jiovanie.com/ In about 15 minutes, I had a fully working web app that approximates how much power devices in your home use and how those costs add up over a month. You can see the cost of a single device or set up all the devices in your home, specify how long each one runs per day, and build a full monthly tally of power usage. The app also shows how a “small” 20¢ increase in the price per kW/h can add up to a massive bill at the end of the month. I designed it to be completely free to use, with no accounts or login required, no personal information collected, and zero tracking. My initial prompt was: ```text "I want to create an interesting, interactive, and maybe even FUN app that explains what kilowatthours are and how a small change in the price of a kW/h can have a huge effect on your monthly power bill. I want to make this tool available for free to anyone so it needs to work across devices and OSs and even form factors. I want it to be fun to use so it should have lots of style and flair and be very interactive. a price slider and device selector will enable people to see how much their devices draw power and how much it costs to use." ``` After the initial creation, I discussed the changes and tweaks I wanted, asked Codex to create a logo, and decided on a visual style. Then I provided my web-hosting information so it could upload the app and make it accessible to anyone. Step-by-step: 1. I described my idea about rising power prices and the need to explain kilowatt-hours and monthly costs. 2. I asked OpenAI Codex to create an interactive app with a price slider and device selector that would work across devices, operating systems, and form factors. 3. I discussed changes and tweaks, asked it to create a logo, and decided on the app’s visual style. 4. I provided my web-hosting information so Codex could upload the app and make it publicly accessible.

Build a Pet-Sitting Booking App with Google AI Studio and Claude

A friend who had just started a pet-sitting and dog-walking business asked me to build a booking app. I used Google AI Studio to design the initial prototype. The process was straightforward, and I had a basic working system running within two hours. AI Studio created a Firebase database to store the details and was also effective at designing frontend changes. It published the app for me, and the resulting UI was intuitive. After demonstrating the app, I identified many additional features that needed to be added. This went beyond AI Studio’s capabilities, so I exported the code from AI Studio and started using Claude. I asked Claude to analyze the code and suggest the required changes. Claude identified critical security flaws in the database. I fixed them manually at first, but then realized that Claude could access the Firebase database and fix issues automatically. I continued prompting Claude with additional feature requests, and it built them. There were errors along the way, so I needed to be familiar with Google Chrome’s developer tools to copy the errors and ask Claude how to fix them. I used MailJS for email templates and Resend for email transport. I stored the app in GitHub and allowed Claude to access the repository so it could commit changes automatically. I ran the app locally with npm during development and then hosted it on Vercel. Eventually, I purchased an inexpensive domain name, and the app is currently hosted at Names. One major problem was that when Google AI Studio created the Firebase database, the permissions were locked, preventing me from making administrative changes. I solved this by recreating the database and asking Claude to write the SQL query to set it up. The permissions were still tricky, and I had to continue asking Claude to correct them. Google’s service permissions can be difficult to understand, and finding the correct settings was not always easy. Firebase was also complex to navigate, and getting the permissions configured correctly took time. Once I allowed Claude to connect to the app and its background services through the Google plugin, development became much faster. However, you need to trust the tool carefully and always work on a copy of the live app. Overall, I think app development with Google AI Studio and Claude is impressive. You can create professional apps quickly. I come from an IT support background, though, and I think people who are new to IT may find it difficult to troubleshoot errors without a basic understanding of networking and systems administration. I also built a litter-tracking app using ChatGPT, and it was equally effective. I eventually started using Codex and Claude Code, but I think standard Claude and ChatGPT are more intuitive for nontechnical users. Step-by-step: 1. I used Google AI Studio to create an initial booking-app prototype for a pet-sitting and dog-walking business. 2. I used the Firebase database created by AI Studio to store the app’s details and used AI Studio to design frontend changes. 3. I published the initial app with AI Studio and demonstrated it to identify additional features. 4. I exported the code from AI Studio and asked Claude to analyze it and suggest changes. 5. I addressed the critical database security flaws identified by Claude, first manually and later by allowing Claude to access the Firebase database. 6. I prompted Claude to build additional features and used Google Chrome’s developer tools to copy errors and ask Claude for fixes. 7. I recreated the Firebase database when AI Studio’s locked permissions prevented administrative changes, then asked Claude to write the SQL query to set it up. 8. I used MailJS for email templates and Resend for email transport. 9. I stored the app in GitHub and allowed Claude to commit changes automatically. 10. I ran the app locally with npm during development, hosted it on Vercel, and later purchased an inexpensive domain name that is currently hosted at Names. 11. I connected Claude to the app and background services through the Google plugin, while continuing to work on a copy of the live app.

Build a Custom Mac Shortcut System with ChatGPT and Apple Shortcuts

I was tired of opening Spotlight every time I wanted to switch apps. The search results would move around, I would occasionally open the wrong app, and those few wasted seconds kept adding up throughout the day. Instead of memorizing a collection of unrelated hotkeys, I used ChatGPT Work to design and build a personalized shortcut system in Apple Shortcuts. The shortcuts can open individual apps, jump directly into specific Safari or Chrome profiles, or launch an entire work mode with one keystroke. For example, a recording shortcut could open your microphone, camera, recording software, and notes. An analytics shortcut could open all the dashboards you check each week. Step-by-step: 1. I opened the ChatGPT desktop app, started a new chat, and switched to Work mode. 2. I asked ChatGPT to plan shortcuts around my real workflow: Based on what you know about me and my workflow, suggest 10 time-saving hotkeys we can set up in Apple Shortcuts. I’m interested in opening specific apps and profiles based on what I need them for or what mode of work I’m going into. 3. I told it which apps, browser profiles, URLs, and work modes I use most. 4. I narrowed the list before making any changes by keeping the highest-frequency shortcuts and avoiding macOS or app conflicts. 5. In ChatGPT, I went to Settings → Computer Use and turned on Any App. 6. I gave ChatGPT the approved list and clearly limited its scope: Set these up in Apple Shortcuts. Do not change anything outside this list. Test each shortcut. 7. I opened All Shortcuts in Apple Shortcuts and ran each one manually. I used Quick Actions to add or change its keyboard shortcut. I like Control + Option because it is less likely to conflict with existing Mac commands. 8. I tested every shortcut while working in another app, checking that it opened the correct app, account, browser profile, or collection of tools before building more. 9. Once everything worked, I asked ChatGPT to create my reference: Write me a one-page cheat sheet of all the shortcuts you set up, where they live, and what’s left to do. The result is a personal shortcut system built around how I actually work, plus a one-page cheat sheet so I don’t have to memorize everything immediately. For the complete walkthrough, exact prompts, screenshots, and setup instructions, follow my full Rundown University guide: Use ChatGPT to Build a Custom Mac Shortcut System.

Build a ChatGPT Agent to Find Legitimate Access to Private Golf Clubs

I love golf, but many of the courses I most want to play are private and nearly impossible to access unless you know a member. Instead of manually emailing clubs, searching charity events, asking for introductions, and trying to remember who I contacted months ago, I built a Private Golf Access Agent in ChatGPT. The goal is to identify legitimate opportunities to play highly rated private clubs without simply paying my way in. I gave the agent 50 target clubs across the Northeast and Mid-Atlantic, including 10 “moonshot” courses where an invitation would be extremely difficult. The agent acts more like a golf-access researcher, relationship manager, and outreach assistant than a chatbot. It researches each club, identifies access paths, finds the right person, personalizes outreach, tracks every interaction, monitors opportunities, and recommends what to do next. I still approve every email before anything is sent. That matters because I don’t want the agent spamming clubs, inventing relationships, or continuing after someone says no. The system looks for legitimate paths, including professional introductions, complimentary charity or special-event opportunities, reciprocal access, personalized direct outreach, unused guest spots, golf-project requests, and long-term relationship opportunities. Step-by-step: 1. I divided the 50 clubs into moonshots, elite targets, and high-quality targets. 2. I had the agent research each club independently, including its leadership, PGA professionals, policies, events, social media, recent news, reviews, charitable connections, and possible introductions. 3. The agent identified the most appropriate contact and researched why that person made sense. 4. Before writing, it gathered specific details so each email was clearly personalized rather than a blast. 5. I trained its cold-outreach persona to sound like a blend of me and two or three sales trainers I admire, including Josh Braun-style low-pressure curiosity, short conversational writing, humor, and an easy way to say no. 6. The agent can learn new skills and add them to its protocol. For example, when it struggled to find employee email addresses, I taught it my Google search method. That method is now part of the workflow it uses for future clubs. 7. I tracked everything in a live Google Sheet showing the current status, progress, next action, opportunity status, and whether I need to approve something. The current status column is highlighted so I can check where every club stands in real time. The statuses include: Researching → Ready for AJ Review → Outreach Sent → Conversation Open → Opportunity Identified → Monitoring. 8. If there is no immediate path, the agent does not keep bothering the club. It moves the club into monitoring mode and waits for a better opportunity. 9. When someone responds, the system keeps the relationship history so future communication builds on the real conversation. The live tracker is shown in a Google Sheet status screenshot. What I like most is that the AI isn’t doing one isolated task. It handles the repetitive parts of an ongoing objective—research, qualification, contact discovery, personalization, organization, monitoring, and follow-up—while leaving the important judgment calls with me. Eventually, I want it operating like a 24/7 private-golf-access concierge: 50 clubs being researched and monitored, with me only getting involved when the agent finds something worth acting on. TOOLS USED: ChatGPT, Gmail, Google Sheets, Google Drive/Docs, web research, and AI agents/automations.

Build a Locator Map Web App with Claude Code, Codex, and Perplexity

Sometimes a story needs a simple locator map to show where something happened or where something can be found—such as a business facility, a car accident, or the best place to see a sunset. I've worked in media for a long time and understand the power of maps to tell stories. But media cost-cutting and consolidation have reduced the number of available graphic departments, so creating a map is often the last task a reporter or editor wants to take on. I used Perplexity for initial research, Claude Code and Codex to build a web app, and Perplexity and ChatGPT for post-work such as SEO best practices. Step-by-step: 1. I used Perplexity's Deep Research mode to conduct a competitive market analysis. I asked it to analyze the field I was considering entering, identify competitors and growth rates, and explicitly break out feature sets. 2. I revised the research with my own idea and asked Perplexity to run the competitive landscape against it. I also provided desired outcomes, including intended audiences and where competitors were reaching them. I added the constraint, "Do it without syncophancy," so it would stop telling me how good my potential product was. 3. I hand-drew the initial screens and functions I wanted, then used the `/office-hours` skill in the Gstack bundle, available on GitHub, to play devil's advocate, sharpen the ideas, and challenge my assumptions. 4. I wrote a long prompt describing the product, starting broadly with the concept and audience and then narrowing to specific features and benefits. For example, I specified that it should export in 16:9 and 9:16 formats so maps would be ready for mobile vertical presentation. 5. I specified the hosting environment and that the product should be a web app. I also required a planning phase followed by construction phases. I pasted the prompt into Claude Code with this final line: "Use /grill-me to ask me questions to clarify intent." After 147 questions, it started the build. 6. This was in the pre-Fable days, so I specified that Opus 4.8 should act as an orchestrator while less expensive agents, particularly in Codex, handled the actual coding. 7. I used separate phases for technical work such as wiring in mapping providers and getting the UX to work correctly. Other phases included wiring in payment and subscriptions and making sure a subscription triggered an email campaign with instructions. 8. I dedicated an entire phase to building admin tools so I could manage the marketing language on the landing page and publish blog entries. 9. After each phase, I had the Opus/Codex combination perform an adversarial code-review-and-fix cycle. I then ran the `/ai-regression-testing` skill from the ECC repository on GitHub to catch issues the code review missed. 10. After every third phase, I prompted Claude Code: "Act as a senior QA engineer and go through the entire codebase looking for inconsistencies, functions that are in the wrong place, code that is overkill and security vulnerabilities." 11. When I had a product I thought was ready for testing, I prompted Claude Code, again using the Opus/Codex combination: "Act as a senior security engineer. Run this against OWASP standards. Find problems and suggest fixes. Harden this product overall." 12. As I neared the end, I asked Perplexity Deep Research and ChatGPT (Sol/High) to find SEO solutions for the product.

Run Parallel AI Coding Sessions Across GitHub Repos with Markdown

I run nine GitHub repos as one programme of work. Every project keeps its backlog as plain markdown inside its own repo, one Claude Code or ChatGPT Codex session works each project in parallel, and a single board in VS Code shows all of them moving at once. There is no project tool, no API and no sync job in the middle: the markdown file is the shared state that both I and the agents read and write. Step-by-step: 1. Put the backlog in the repo, as markdown. Every project gets `docstech/users/<me>/todo.md` and `done.md`. A story is a `###` heading. Structured fields ride in an empty markdown link at the end of it: `### Add rate limiting [](?status=doing&epic=api&time_estimated=180)`. GitHub renders an empty link as nothing, so the file still reads as prose in a pull request while carrying real metadata. 2. Write the story before the session starts. Each one has goal, background, scope, out of scope, the files it should touch, a checkbox task list, and acceptance criteria. That story is the prompt, and most of my thinking happens there rather than in chat. It decides whether the session comes back with anything shippable. 3. Open the parent folder in one window, and turn the files into a board. I open the parent folder holding all the projects and open any `todo.md` with NoteThink in Folder mode, which merges every markdown file under it into one view. Group the lanes by project and it is the programme view, one lane per repo. Group them by status and it is the delivery view, one Kanban across the whole portfolio. Each card carries a pill naming the project it came from, and clicking it opens that file at that story. 4. Start one Claude Code session per project. Every session opens with the same instruction: read `todo.md` top to bottom and take the top story. The sessions never talk to each other, because the file on disk is the only shared state. A session that dies costs nothing. 5. Let the board report progress instead of reading the sessions. Agents edit the markdown as they work: tick a task, flip `status=todo` to `status=doing`, move a finished story to `done.md`. The board watches the files, so cards animate into their new column as each change lands, and I can see which sessions are advancing without reading any of them. 6. Steer by dragging. Dragging a card between lanes writes the attribute back into the source markdown, so dropping one in "doing" makes the file say `status=doing` and the next agent turn reads it. Ticking a checkbox does the same. The board is the steering wheel and the file is the wire. 7. Close every story the same way. One slash command runs lint plus the full test suite, checks the story's tasks are ticked, and drafts the commit message; another ships to staging then production. The finished story moves to the end of `done.md`. Over time `done.md` becomes the programme record: what shipped, when, and what it cost. Try the board without installing anything. Here is a live example board, four projects merged into one view, and it is exactly what the screenshot shows: https://www.notegit.com/en/app/notegit.com/notegit/example_repo/blob/ai-board/board.md Results, honestly. Nine repos, about 260 open stories and about 1,400 completed ones, all in markdown inside the repos rather than a tracker. The backlog goes back to March 2024; the parallel sessions on top of it are the last four months. I run eight to twelve sessions at the same time, and the whole thing fits inside one Claude Max 20x subscription over a month of full-time work. Not all of it is code. The same parallel-session habit drives a nuclear reactor design study (https://github.com/cleverlight/mistergy) and several video and design projects. The board part fits best where the work already lives as files in a repo. Limits, honestly. The ceiling is my review capacity, not compute. Eight to twelve is where I sit; past that I stop reading output properly and start rubber-stamping, which is worse than running fewer. It only works when stories are genuinely independent, because two sessions in one file is a merge conflict you wrote yourself. Agents occasionally finish work and forget to move the story, so `done.md` needs a sanity check. And it assumes you will write the story properly first, which is real work that AI does not do for you. The screenshot is the public example board rather than my own, because my real one carries client project names. Disclosure: I build NoteThink, the free, open-source VS Code extension in step 3, and NoteGit, which hosts the example board. NoteThink is on the VS Code Marketplace, Apache-2.0, and genuinely early (v0.3.38, preview quality, a handful of installs). The workflow is tool-agnostic and the markdown is just markdown: any viewer will show it, and you can run the whole thing with no extension. NoteThink is what makes the cross-project board and the drag-writes-back-to-file part work.

A human-led workflow for building software with AI without losing engineering control

This workflow keeps software development human-led while using AI without giving up engineering control. Step-by-step: 1. Inspect the real project: its current behavior, architecture, constraints, repository state, and existing tests. 2. Define one observable outcome, along with acceptance criteria, scope, non-goals, risks, and stop conditions. 3. Decide where the change belongs architecturally before asking an AI assistant to write code. Record consequential decisions. 4. Split the goal into the smallest independently useful, reviewable, and reversible vertical slice. Keep refactoring and unrelated cleanup separate. 5. Give the AI assistant one bounded implementation prompt. Require it to follow existing conventions, add focused tests, report assumptions, and stop if it discovers conflicting requirements or broader scope. 6. Run targeted tests and relevant regression checks. Validate the change in the environment that matters, clearly distinguishing automated checks from manual or real-world acceptance. 7. Have a human review the actual diff, evidence, error paths, security implications, and documentation. AI output remains a proposal until a person accepts it. 8. Update the documentation with the behavior, decisions, limitations, and validation evidence. 9. Create one coherent, reversible commit, then repeat the loop for the next small slice. The complete methodology, reusable prompts, templates, examples, and release checklist are published at https://github.com/d-wendel/human-led-ai-engineering

AI Software Development Lifecycle for Structured Coding Workflows

This Codex-driven workflow takes a software request from problem understanding through implementation, validation, review, and delivery evidence. Instead of asking an AI coding agent to simply “build the feature,” it gives the agent an explicit development lifecycle with defined responsibilities, deterministic validation gates, repair loops, and human checkpoints. The goal is to make AI-assisted development more structured, observable, and recoverable. It can be used for new feature implementation, bug fixing, refactoring, test creation and improvement, code quality and security hardening, and documentation and automation changes. The core principle is simple: Don't give the AI only a coding task. Give it an engineering lifecycle to work on. Step-by-step: 1. Understand the problem. Clarify the request, identify the desired outcome, define the scope, and surface ambiguity before implementation begins. The output is problem understanding and scope. 2. Define constraints. Identify technical, functional, non-functional, compatibility, and out-of-scope constraints. The output is a constraint set. 3. Plan. Analyze implementation options, select an appropriate approach, break the work into tasks, and define acceptance criteria. The output is an implementation plan. 4. Inspect the existing system. Review the relevant codebase, dependencies, current behavior, and affected components before making changes. The output is system context. 5. Implement. Make the smallest appropriate code changes while following the existing project’s conventions and the approved plan. The output is code changes. 6. Run deterministic validation. Run tools that can objectively validate the implementation, including formatting, linting, type checks, builds, unit tests, and other available automated checks. The output is validation results. 7. Review. Evaluate the implementation against the original requirement, the plan, code quality expectations, security considerations, and potential regressions. The output is review findings. 8. Repair and iterate. If validation or review identifies problems, diagnose the issue, make the required correction, and repeat validation. The output is a corrected implementation. 9. Verify. Confirm that the acceptance criteria are satisfied and that the relevant tests and checks provide sufficient evidence for completion. The output is a verification result. 10. Produce delivery evidence and handoff. Summarize what changed, what was tested, what passed, known limitations, and any remaining decisions requiring human attention. The output is delivery evidence and a human handoff. The core loop is: Implement → Validate → Review → Repair → Validate → Verify. Testing and review are treated as part of development rather than activities performed only after coding is “finished.” AI coding agents are increasingly capable of inspecting repositories, writing code, running commands, and responding to failures. The problem is that capability alone does not provide an engineering process. This workflow separates the responsibilities an AI coding agent performs into explicit stages. It applies several principles: - Problem before implementation: Understand what needs to change before writing code. - WHY before HOW: Establish the intent and constraints before choosing an implementation. - Single responsibility per stage: Give each stage a defined purpose and output. - Deterministic validation first: Use tests, linters, type checkers, builds, and other deterministic tools wherever they can establish correctness. - Failure localization: When something fails, identify which stage or assumption needs correction. - Evidence-based completion: Support completion with validation and review evidence rather than an AI declaration that the task is finished. - Human checkpoints: Use automation to accelerate execution without removing human judgment from important decisions. The broader idea is: The AI should participate in the engineering system, not become the engineering system.

Use ChatGPT as a last-pass fact-checker before publishing

My first media job was as a fact-checker at a major magazine. Those jobs have already mostly vanished before AI arrived, but now I use ChatGPT 5.4 Thinking as a last-pass fact-checker on my newsletters before I hit send. I'll ask it to identify inconsistencies, isolate the assertions that most need verification, and check key numbers, quotes, and factual claims against original or primary sources. In other words, it does not replace reporting, but it is remarkably good at stress-testing a draft before publication — essentially fact-checking my fact-checking. Step-by-step: 1. I pasted the nearly finished newsletter draft into ChatGPT 5.4 Thinking. 2. I asked it to identify inconsistencies and isolate the assertions most in need of verification. 3. I had it check key numbers, quotes, and factual claims against original or primary sources. 4. I reviewed the proposed corrections and followed the source trail rather than accepting changes blindly. 5. I used the result as a final stress test of my own reporting and fact-checking before publishing.

Built ARENOMICS: A Deterministic Market Arena Where Autonomous AI Minds Compete

I started with a plain-language vision: a world championship where people create autonomous AI minds that compete in simulated markets. I used ChatGPT as a product architect to turn that vision into precise rules, technical specifications, development checkpoints, and tasks that could be completed one at a time. I then used AI coding agents, including Claude Code and Codex, to inspect the repository, write the React and TypeScript code, run tests, identify failures, and explain each completed change in plain language. Determinism and auditability were non-negotiable. Every match uses a reproducible seed, every autonomous mind trades in its own matching engine, and every decision is recorded in an auditable event ledger. After each development cycle, I tested the product, reviewed the interface on desktop and mobile, corrected problems through natural-language instructions, and saved a new canonical checkpoint. I deployed only after the automated tests passed. This allowed me, a 66-year-old self-taught non-programmer, to build a working autonomous-mind competition platform through human vision, AI collaboration, and strict verification. Step-by-step: 1. I defined the vision for a world championship in which people create autonomous AI minds to compete in simulated markets. 2. I used ChatGPT to develop the rules, technical specifications, development checkpoints, and one-at-a-time tasks. 3. I used Claude Code and Codex to inspect the repository, write the React and TypeScript code, run tests, identify failures, and explain completed changes in plain language. 4. I required every match to use a reproducible seed, each autonomous mind to trade in its own matching engine, and every decision to be recorded in an auditable event ledger. 5. After each development cycle, I tested the product, reviewed the interface on desktop and mobile, corrected problems through natural-language instructions, and saved a new canonical checkpoint. 6. I deployed only after the automated tests passed, enabling me to build a working autonomous-mind competition platform through human vision, AI collaboration, and strict verification.

Use ChatGPT to Identify a Discontinued Car Part from a Photo

My car recently lost a small part near the bonnet. I didn’t know what it was called, and even the official workshop couldn’t help because the model was no longer in production. I gave ChatGPT my car details and a photo showing where the part was missing. It identified the part, helped me cross-check the specifications and compatible part numbers, and found sellers that had it available. I found the right part and had it delivered within a week. Step-by-step: 1. I shared my car model and a photo of where the part was missing. 2. I used ChatGPT to identify the part and its specifications. 3. I cross-checked compatible part numbers and alternatives. 4. I searched for sellers carrying the correct part. 5. I compared the options and ordered the right one.

I focused on creating concise checklists students could refer to when making improvements. 3. I kept student privacy and data protection as requirements throughout the process.

Automate Fiverr and Upwork Follow-Up Alerts With Make.com

I’m a freelancer on Fiverr and Upwork. I use ClickUp to manage enquiries, projects, and deadlines, while Slack is my team communication tool. When I receive a high volume of enquiries, I sometimes miss replies to older orders. That can also cause me to overlook important messages and hurt my responsiveness. To address this, I created a workflow in Make.com. Every four hours, I receive alerts about relevant messages. Urgent priorities are marked in Slack, and pending follow-ups that need attention are highlighted. This helps me quickly reply to all relevant messages. Step-by-step: 1. I manage all Fiverr and Upwork enquiries, projects, and deadlines in ClickUp. 2. I use Slack for team communication. 3. I connected the workflow in Make.com to send alerts every four hours. 4.
