From idea to build-ready spec or prompt

Three steps from rough input to something you can build from.

01

Drop in a rough prompt or a one-line app idea.

02

Fast for quick drafts, Balanced for most specs, Strongest for the most detail. Every plan can use all three.

03

Paste it into ChatGPT, Claude, Cursor, or Lovable.

What is a PRD, and why do AI coding tools need one?: A PRD (product requirements document) spells out what to build: the screens, the data, the rules and how to tell it works. AI coding tools build what you say, not what you mean, so without one they fill every gap with a guess. A good PRD answers those questions before any code is written.
Does it work with Cursor, Claude Code and Lovable?: Yes. The spec is plain Markdown, so you can save it as SPEC.md in your project or paste it into any AI coding tool, including Cursor, Claude Code, Lovable, Bolt, v0 and Replit.
What does the free prompt improver do?: Paste a rough prompt for ChatGPT, Claude, Gemini or any other model, and it rewrites it with a clear task, context and output format, then explains what it changed. Anything only you know becomes a placeholder to fill in. You can try it without an account.
What's in the free trial?: A new account gets 25 credits for 7 days, with no card needed, and every model is included. A spec costs 1 to 6 credits depending on the model, and a spec that fails or comes back cut off costs nothing.
