BuildBrief is an AI architect that interviews you about your app idea, makes smart technical decisions automatically, and generates a comprehensive spec you can hand to any AI coding agent.
Everything you need to go from "I have an idea" to "here's the complete spec".
A dynamic 5–10 question flow that adapts to your project's complexity. Not a fixed questionnaire — the AI decides what matters.
The AI silently makes non-critical technical decisions — database type, auth method, folder structure — so you can focus on what matters.
Export your spec formatted for Cursor (.cursorrules), Windsurf (.windsurfrules), or Bolt. One spec, every tool.
Post-spec AI-generated implementation checklist with phases, priorities, and time estimates. Check off tasks as you build.
Your interview progress survives tab closes and page refreshes. Come back anytime within 24 hours and pick up where you left off.
Automatic retries, Go Back, and Start Over — at every step. No more losing progress to a network hiccup.
Seven steps from napkin sketch to production-ready spec.
"A Tinder for adopting rescue dogs" is enough. BuildBrief handles the rest.
Get a vision statement, suggested app name, implementation approaches, and honest cautions — instantly.
The AI asks only what matters architecturally. 5–10 questions max. It infers the obvious stuff.
The sidebar fills with smart technical defaults the AI chose for you. Override any of them if you disagree.
A multi-page technical specification covering user stories, data models, API endpoints, and tech stack.
Optional: generate a phased implementation checklist with priorities and time estimates.
Download for Cursor, Windsurf, or Bolt. Paste and start building immediately.
Clone the repo, add your OpenRouter key, and start turning ideas into specs.
