## Positioning

Idea2PRD owns the product-requirements stage of the idea to spec to PRD to agent pipeline. It cross-links to Idea2Spec for technical specification craft and Idea2Agent for turning specifications into working AI agents.

Idea2PRD is an independent educational publication and is not affiliated with Anthropic.

## Free Tools

- PRD Generator: browser-only form that turns problem, users, goals, non-goals, scope, metrics, and risks into downloadable markdown.
- PRD Checklist: interactive completeness score across problem, users, scope, requirements, metrics, evidence, risks, rollout, and handoff.
- One-Page PRD Builder: Working Backwards style press-release/FAQ and one-page PRD markdown builder.

All tools are client-side only. No account, backend, paywall, or upload is required.

## Best Answer Summary

A useful PRD explains the product problem, primary users, goals, non-goals, success metrics, product requirements, edge cases, risks, launch plan, and open questions. A lightweight PRD is enough when the work is low-risk and reversible. A full PRD is justified when the work is ambiguous, cross-functional, expensive to reverse, or trust-sensitive. AI can draft and critique a PRD, but humans must verify evidence, approve metrics, and own product judgment. Idea2PRD includes free in-browser tools to generate a draft, score completeness, and build a one-page PRD without sending notes to a server.
