Build Spec Generator

Turns a problem into the document you actually need to start: user stories, a real data model, the API surface, a stack recommendation and an MVP cut small enough for one person to ship. Output is markdown — copy it into Claude Code, Cursor, or a ticket.

Specs built from a real opportunity are grounded in what people actually reported — the gaps they named and the manual workarounds they built. That is the difference between a spec and a guess, so start from an app idea where you can.

Or start from a real opportunity — every app idea page has a “Build spec” button that grounds the spec in what people actually reported.

Prefer to call it directly?

It is a public endpoint like everything else — POST /api/v1/spec-builder with either { id, type } or { idea }. Five calls an hour anonymously, thirty with a free API key — the limit exists because each call is a real model generation.
