A product spec, screen plans, and build steps for your coding agent.

Your first Build Kit is free with a verified email.
Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

I used to think I could not move forward because I did not have enough time. Even when I had five minutes free, they were gone by the time I decided what to do. Small things I meant to handle stayed unfinished for days. Little by little, I began to think, “Maybe I am simply not someone who can make progress.” I was losing more than a few minutes. I was also losing trust in my ability to move my own life forward. I am not successful yet. Still, I now devote much of my time to development, and I feel that I am moving my life forward more than I used to. I did not suddenly become a stronger person overnight. I made a little progress. I moved one thing forward today. I made something slightly better than it was yesterday. As those small facts accumulated, my trust that I could make progress gradually returned. Action creates confidence, and that confidence leads to the next action. MinPick is an app for creating that first small step. Save things you want to do later together with their estimated duration. When some time opens up, simply choose how much time you have right now, such as 3, 5, 10, or 15 minutes. MinPick shows only tasks that are likely to fit within that time. You do not need to review a long to-do list. You do not need to reconsider all your priorities. Choose one thing you can do now and begin. Five minutes will not change your entire life. But the fact that you made progress in those five minutes remains. That fact becomes trust in yourself: “Maybe I can make a little progress next time too.” As that small trust continues to accumulate, it may eventually change how you use your time. MinPick is not designed to fill every free moment with productivity. When you need rest, rest without guilt. Use MinPick only when you want to move one thing forward but cannot decide where to begin.

Hypothesis 1
Assumption to check: Many productivity apps lack effective task organization tools.
Validate with people who use this workflow before building.
Hypothesis 2
Assumption to check: Users often find task management apps overly complicated.
Validate with people who use this workflow before building.
Hypothesis 3
Assumption to check: Syncing tasks across devices can be unreliable.
Validate with people who use this workflow before building.
Hypothesis 4
Assumption to check: Poor customization options for tasks and projects.
Validate with people who use this workflow before building.
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
Not assessed in a Build Kit yet.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
