I built a family archive website to host handwritten letters and photos from a relative's 1942/43 stint in basic training. I built everything through prompts, and it could help anyone with scanned family papers who wants them searchable and open to AI chat. 1. I designed the basic website in Google AI Studio. 2. I migrated the project to Replit for the build-out and hosting. 3. I used Firebase for PDF and photo storage, and a Firebase database for users and data indexing. 4. I built a PDF upload workflow that extracts text from the handwritten letters. 5. I chunk the PDFs for faster retrieval, since the files are large. 6. The workflow creates a search index and a vector database for AI chat. 7. I created server APIs to retrieve data and content, which avoids CORS issues. The result is a site where the letters and photos can be searched and queried through AI chat.

“A good engineer knows when not to use AI.” I built a semi-automated workflow to summarize my live streams. With it, I can record and edit a stream in just one day of work. Not everyone has time to watch an entire stream, so creating a summary of the main moments is important for people who want to watch it later. Many tools create Shorts from videos by analyzing transcripts, but they are expensive and do not work well for visually heavy content such as gameplay. Gemini can analyze both video and audio and has a long context window, so I decided to use Google AI Studio to identify important moments. I also created scripts to automate parts of the video-editing process. Some of the scripts can be executed by an agent, and the prompts can be turned into Skills when using the API. Step-by-step: 1. I record the video with separate tracks for the microphone and background audio. I keep the microphone on the first track so the LLM does not identify only the background audio. 2. I compress and cut the video with `ffmpeg`, then extract the audio tracks. Google AI Studio has implicit video requirements: files must be under 400MB and under one hour long. The AI analyzes only one frame per second, so I can also lower the FPS to save space. I use the audio tracks later in the workflow. 3. I upload the processed videos to Google Drive, which makes them easier to use in Google AI Studio. 4. I use Gemini with temperature 1 and a high thinking level to select the important moments. I add the system prompt and specify which part of the video I am uploading: "The video is part X of the stream. Please make a structured script according to the system instructions." This helps Gemini understand what types of moments may appear in the video. The system prompt was created for gameplay presentations but can be adapted for other content. 5. I use Gemini Pro with temperature 1 and a high thinking level to find the timestamps for the selected moments. I keep timestamp generation separate from moment selection so Gemini has more thinking time for each task. Gemini Pro works better than Flash when handling time. I add the system prompt along with a copy of the response from the previous step. - As an extra check, after execution I continue the conversation with: "Check if the analysis was cut off too early (context truncation), ignoring that the video continued and generating false positives for timestamps. Check the last events especially." 6. I send the data to Blender. I create a JSON file containing the AI’s response and use a script to add the original video, the microphone track, and the background audio track. The script cuts and marks the important moments based on the JSON. Because it is not possible to send multiple audio tracks from a single video, I send the tracks separately. I also make sure to use the correct FPS, either 30 or 60. 7. I edit the video manually. The AI’s timestamps are not perfect, so I may add or remove sections, or correct a position that the AI identified incorrectly. I then render the video. 8. As an extra, I can automate standardized edits. For example, I use three different camera positions, so I add clips to three different tracks depending on the position I want. I use a script to change the position and scale of the clips on those tracks. 9. As another extra, I transcribe the audio. I mute the background audio and save only the microphone audio as an MP3, then use Whisper to transcribe it. I can use the transcript as YouTube subtitles or embed it directly into the video. I use Whisper-WebUI with Log probability Threshold -0.5, No Speech Threshold 0.5, Patience 2, and Hotwords `\u003cmy name and terms in other languages I usually use\u003e`. I use an LLM to translate the transcript into other languages. 10. Finally, I create tags and titles. I upload the transcript to Google Drive and use it in Google AI Studio with a system prompt to generate tags and titles for the video. I also use the assistant in Google AI Studio to analyze and summarize my channel for use in LLMs. This helps me choose better titles and tags.

I built an AI-assisted Lightroom Classic workflow that lets photographers create branded marketing images without leaving Lightroom. The problem I wanted to solve was simple: photographers often finish editing an image, export it, open another design tool to add a logo, watermark, text, or promotional graphic, and then export it again. I wanted that entire branding step to happen inside Lightroom. Using AI-assisted development, I built Brandstamp Pro, a Lightroom Classic plugin that lets me add branding, preview the result, save reusable presets, and export the finished image from the same workflow. The result is a much simpler process: edit photo → add branding → preview → export Instead of: edit photo → export → open another design app → add branding → export again I originally built it for my own real-estate photography workflow, but the same idea works for photographers who need branded social images, booking graphics, promotional images, watermarks, or client-ready marketing photos. The biggest benefit is not that AI adds the branding automatically. It helped me build a tool that removes a repetitive step from an existing photography workflow. Step-by-step: 1. I selected an edited photo in Lightroom Classic. 2. I opened the Brandstamp panel. 3. I added a logo, watermark, text, or other branding. 4. I adjusted the size, position, opacity, color, and placement. 5. I previewed the branded result before exporting. 6. I saved reusable presets for branding I use repeatedly. 7. I exported the finished branded image directly from the same Lightroom workflow.

I kept forgetting who I had lent books to, and spreadsheets felt like overkill. So I built Runo, a book-lending app for friends, without traditional coding. Runo (runo.club) is a web app where I can catalog my home library, get a unique shareable link, and let friends browse my books and request to borrow them. I can approve or decline each request with one click. Step-by-step: 1. I used Claude to think through the feature set, data model, and UX flow before writing a single prompt. This helped me avoid building the wrong thing first and gave me a clear blueprint for the Lovable prompts that followed. 2. I used Claude to create precise, narrowly scoped prompts for Lovable, with each prompt focused on a single change so existing functionality would be less likely to break. This significantly conserved Lovable credits. The React, TypeScript, and Supabase stack came out of the box. 3. I added two ways to scan books instead of requiring users to type titles manually: - Barcode scanner: Point the camera at an ISBN barcode to autofill the title, author, and cover using the Open Library API. - Cover photo scanner: Photograph the cover so Gemini 2.5 Flash can extract the title and author in under 2 seconds. 4. I routed the cover scanner through a Supabase Edge Function using Lovable’s AI Gateway, so the API key never touches the client bundle. 5. For every bug fix and feature, I followed the same iteration loop: describe the problem to Claude, get a precise Lovable prompt, push the changes to GitHub, and let Lovable auto-sync them. Claude and Lovable’s bidirectional GitHub sync made the process feel like pair programming. Tools used: Lovable, Claude (Sonnet), Gemini 2.5 Flash (via Lovable AI Gateway), Supabase, and GitHub. Live at: runo.club — public beta and free to use. Feedback welcome. #appbuilding #vibecoding #buildinpublic #lovable #nocode

I kept struggling to stay consistent with social media for my own projects. Writing captions, choosing hashtags, designing graphics, and scheduling content across platforms was taking hours every week—time I would rather spend building. So I built AutoKonnekt. You give it one sentence or a website URL, and it generates a full month of on-brand social posts, including captions, hashtags, and AI-generated images. It then schedules them across Instagram, Facebook, LinkedIn, TikTok, Pinterest, X, and Threads. The hardest part was getting the AI to sound like a specific brand’s voice instead of producing generic marketing copy. That took a lot of iteration on the prompting side. It’s live now with a free plan if anyone wants to try it: https://autokonnekt.com I’d love to hear what the community thinks. For those of you managing social media manually, which part takes the most time? I’m trying to figure out what to build next. Step-by-step: 1. I enter one sentence describing the project or provide a website URL. 2. AutoKonnekt generates a month of on-brand social posts with captions, hashtags, and AI-generated images. 3. I use the generated content across Instagram, Facebook, LinkedIn, TikTok, Pinterest, X, and Threads. 4. AutoKonnekt schedules the posts across those platforms. 5. I iterate on the prompting to make the content sound like the specific brand instead of generic marketing copy.

GeneTrust AI — Asistente Genético Virtual (AGV) es una plataforma tecnológica concebida bajo una arquitectura basada en evidencia (Evidence-First), asistida por IA y gobernada por humanos. Está diseñada para facilitar el acceso, la estructuración, la exploración, la clasificación, la priorización y la síntesis trazable de evidencia genética y biomédica. Su diseño busca prevenir riesgos críticos de la IA en biomedicina, como las alucinaciones, las referencias no resolubles, la pérdida de procedencia, el ocultamiento de contradicciones y la atribución indebida de autoridad clínica. Aplica operaciones aditivas y no destructivas: filtrar, clasificar o priorizar los datos nunca modifica ni reescribe la evidencia fuente original. Además, preserva la ambigüedad y los elementos no clasificables en lugar de forzar conclusiones artificiales. El stack tecnológico incluye React, TypeScript, Node.js y servicios en la nube. La plataforma integra un enfoque de múltiples proveedores y agentes de IA, con modelos generativos desacoplados, junto con una clasificación multidimensional de la evidencia mediante la abstracción de un Structured Decision Provider (SDP, Proveedor de Decisión Estructurada). Utiliza específicamente TypeSafe AI, con su modelo Jev, como proveedor de decisiones estructuradas bajo estrictas políticas de activación y gobernanza por dimensión. La IA y sus agentes asisten en la organización, exploración y síntesis de información compleja, pero no actúan como una autoridad diagnóstica ni determinan por sí mismos la verdad clínica. Sus salidas se manejan como inferencias computacionales controladas, separadas estrictamente de la evidencia fuente y sujetas a validación humana explícita. Step-by-step: 1. Accedo y estructuro la evidencia genética y biomédica dentro de una arquitectura basada en evidencia. 2. Exploro, clasifico y priorizo la información mediante operaciones aditivas y no destructivas, sin modificar ni reescribir la evidencia fuente original. 3. Mantengo la procedencia, las contradicciones, la ambigüedad y los elementos no clasificables, evitando forzar conclusiones artificiales. 4. Utilizo múltiples proveedores y agentes de IA, con modelos generativos desacoplados, para organizar, explorar y sintetizar la información compleja. 5. Aplico una clasificación multidimensional mediante la abstracción de un Structured Decision Provider (SDP), utilizando TypeSafe AI y su modelo Jev bajo políticas estrictas de activación y gobernanza por dimensión. 6. Trato las salidas de la IA como inferencias computacionales controladas, las separo de la evidencia fuente y requiero una validación humana explícita antes de utilizarlas.
