Forest: From idea to launched product, without building on a guess

For founders and designers building their own product with AI. Forest runs inside Claude Code. It asks why before it asks what, and records how you know each answer.

How it works in 3 steps

Slower, on purpose

Some tools write a PRD in 90 seconds, on guesses. Forest asks first, and tags every answer by how you know it.

  • Watched

    You saw someone do it.

  • Heard

    A named person told you, unprompted.

  • Reasoned

    Worked out from what you saw or heard.

  • Assumed

    Nobody has checked yet.

Would it let this through?

Moments from real projects, dealt fresh each visit. Call each one, then turn the card.

You say it's for “small businesses”.

Would forest let this through?

Not quite.

It pushes back.

It asks for one person you have actually spoken to.

Card 1 of 8.

What you leave with

Each camp works from what the one before it made. Stop at any flag and you leave with what is there.

Every document, on one page

Open project/index.html, or ask /map to open it. It stays on your computer.

  1. Every document, as written

    Each file appears under its camp, with the command that wrote it and when. The ones still owed say so.

  2. Rebuilt as you work

    Every write rebuilds it, and an open tab refreshes itself. It holds nothing the folder doesn't.

  3. Copy what you need

    A whole document or one section, as written or as a prompt for another AI tool.

Questions people ask

Why forest kit?

Because an AI tool will write you a convincing plan in seconds, and nothing in it tells you which parts are true. Forest asks before it writes, tags every claim by how you know it, and can tell you to stop before you build. Each decision is kept with its reason, so the folder still explains itself 2 to 3 months on, to you, a developer or an investor. It's slower than working freehand. Going fast on a guess gets you nowhere sooner. That's the trade.

What are camps?

Forest splits the work into 6 stages it calls camps: Frame, Learn, Decide, Shape, Build and Ship. Each one ends with files you keep.

How long does it take?

The first session takes 20 to 40 minutes. After that, it depends on how long your research takes.

Can you stop and come back?

Yes. Everything lives in the folder. Open it again and type /trail.

What happens after launch?

SUMMIT.md leaves 3 questions dated 90 days out. Answer them cold, and /pack opens cycle 2 with your research, decisions and design carried across.

Does it send your work anywhere?

No. It checks for a new version at most once a day. Usage counts go out only if you say yes, and never your files.

Why it exists

  • For founders

    Plenty of conviction, no evidence yet, and no way of knowing whether the idea solves the right problem.

  • For design founders

    Endless exploration: round after round of ideas, comments on comments, documents nobody reads, and a brief that still isn’t clear.

  • For whoever comes next

    A Slack channel full of ideas, AI‑written documents and decisions nobody checked, and a CMS about to become the bottleneck.
