What's in a blueprint

Every blueprint follows the same format, so you can compare tools and know what you're getting before you build.

  1. 1

    The problem

    One sentence from the person who has it. For example: purchase requests get lost in Slack.

  2. 2

    The drawing

    A labelled drawing of the main screen, so you can see where each part of the tool lives.

  3. 3

    The data model

    The records and fields behind the tool, so the build starts with the right structure.

  4. 4

    The build prompt

    A prompt you can paste into Claude, ChatGPT, Cursor or any other AI builder, plus common variations.

Why this exists

Most business software is built for thousands of companies at once, so every team ends up adjusting its process to fit the tool, and paying per seat for features it never uses.

That trade-off made sense when custom software took months to build. With AI, a small internal tool now takes an afternoon. The hard part is knowing exactly what to build.

This site collects plans for those tools. Each one starts from a real problem and is written up so your team can build its own version, with whichever AI it already uses.

A new blueprint every week

Sent on Sundays. Each email covers one tool: the problem, the drawing, the data model and the prompt.
