Frequently asked questions
What do I get for free?
Two paths: If you're starting from an idea, you get Stage 1 (Discover) and Stage 2 (Define) — a validated idea summary and a professional PRD. If you're importing existing code, you get a GitHub repo scan with auto-generated PRD and architecture docs. One active project either way.
I already have code. Can I import it?
Yes. Connect your GitHub repo and our AI will scan your entire codebase — mapping architecture, extracting schema, identifying tech debt, and generating the documentation your project never had. The initial scan and basic docs are free. Pro unlocks the full doc suite, tech debt report, and Stages 5-8.
What does Pro unlock?
Pro unlocks Stages 3-8: Design, Architect, Plan, Build, Review, and Launch. For imported repos, Pro also includes the full document suite (CLAUDE.md, SCHEMA.md, TECH_DEBT.md, ROADMAP.md), Claude Code prompt generation for cleanup tasks, and .zip export.
Can I cancel anytime?
Yes. Cancel your subscription at any time from the Settings page. You keep access through the end of your billing period.
Do I need to know how to code?
No. Build a Startup generates planning documents and Claude Code prompts. You paste the prompts into Claude Code, which writes the actual code. The entire process is designed for non-technical founders — whether you're starting fresh or cleaning up vibe-coded projects.
What's Claude Code?
Claude Code is Anthropic's AI coding assistant. Build a Startup generates context-rich prompts specifically optimized for Claude Code, so you get better output than writing prompts yourself.
