How To Build a Productivity Tool With Replit + Interview Method

Start with Claude or ChatGPT instead of opening Replit first. The goal is to let AI help you figure out what the app should track before you build anything.

Interview me about my daily tasks so that I can prompt Replit to build me a daily task counting app.

Claude or ChatGPT should ask you a few simple questions and turn your answers into a build prompt for Replit.

• Sales calls
• Deliverables sent
• Client replies
• Internal meetings
• Content published
• Proposals sent

This part matters because the app is only useful if the categories are useful. In the demo, Claude surfaced categories it already knew from previous work, so the interview felt more like a quick sorting pass than a formal questionnaire.

Pro tip: Keep the labels tight. “Admin” is too vague. “Client response” or “Proposal sent” is much easier to count and much more useful in a report later.

Once Claude or ChatGPT gives you the build prompt, paste it into Replit and let it build the app.

• Daily number inputs for each task
• An optional note field
• A calendar heatmap
• A report generator for any date range

In the test for this guide, the generated prompt was pasted directly into Replit and the first working version came together in less than ten minutes.

The important mindset is not “build me a perfect app.” It is “build me something I will actually open every day.”

Before you trust the app with real data, add a few fake days so you can see the system working. Once the calendar starts filling in, the tracker stops feeling theoretical because you can see your work instead of trying to remember it at the end of the week.

• Enter the count
• Add a note if needed
• Save the day

If logging takes more than 30 seconds, people usually stop doing it.

One tweak worth making early is your time zone. AI-built apps often get dates slightly wrong if you do not specify it. Either tell Replit your time zone up front or ask it to let you edit dates manually.

Pro tip: This works because it is task counting, not time tracking. You are not trying to account for every minute. You are just capturing the outputs that matter.

Once you have a few days of data in the app, click Generate Report and choose a weekly or monthly range.

• Total tasks completed
• Daily averages
• Your most active day
• A short written summary

This is the part that makes the tracker useful. The data is already formatted for a manager update, client recap, or team check-in.

• “23 client replies”
• “8 meetings”
• “5 proposals”
• “2 launches”

Now you are not guessing what you did. You have something clean you can send.

The app only works if you use it consistently, so the habit matters just as much as the build.

The easiest version is to update it at the end of your workday. Open it, log the numbers, add one quick note if something unusual happened, and move on.

The point is not to become obsessed with measuring yourself. The point is to have a clean record of what you did so you are not reconstructing your week from Slack, email, and memory.
