Why Greenlit
Build what the market already wants.
De-risk before you build
Every idea is scored on real demand, competition, and saturation — so you commit weeks to something the market is already pulling for, not a hunch.
Skip weeks of research
Competitor pricing, recurring complaints, and the exact gap to exploit — compiled for you, not buried across 40 browser tabs.
Idea → shipping in an afternoon
Generate a PRD, tech spec, and agent rule files tailored to your stack. Hand them to Cursor or Claude and start building.

FAQ
Questions, answered
Where does the market data come from?+
Real signals — search demand, competitor presence and pricing, review complaints, and social mentions — not AI guesses. Estimated figures (cost, complexity) are labeled as estimates.
How is this different from an idea list or newsletter?+
Other tools tell you what to build. Greenlit validates the idea AND hands you a build-ready spec — PRD, tech spec, and agent rule files — so your AI coding agent can ship it.
Which AI coding agents does the build bundle work with?+
Any of them. We generate a PRD, tech spec, CLAUDE.md, .cursorrules, AGENTS.md, and a sequenced task list — drop them into Cursor, Claude Code, or your agent of choice.
What does it cost?+
Free to browse the directory. $9 unlocks one idea's full data and build bundle. $39/mo Pro gives unlimited unlocks plus validation of your own ideas.
Can I validate my own idea, not just the directory?+
Yes. Submit your idea and Greenlit runs it through the same data pipeline, then generates a tailored build spec.
