About PromptPilot
The build-ready blueprint for your app idea.
PromptPilot reads a rough idea, asks the adaptive questions other AI tools skip, surfaces the decisions still open, and hands you a multi-file blueprint for Codex, Cursor, Claude Code, Copilot, and any other AI coding tool.

How it works
From a sentence to a build-ready plan.
Describe your app idea
One line is enough. PromptPilot reads it and builds an App profile — what kind of app it is, who it's for, what data it keeps, and the basics most AI tools never ask about.
/ new blueprint
A hiking app that tracks trails and plans routes with friends.
Answer adaptive questions
Questions tailored to your idea fill the context gaps other tools skip. Each option gives you perspective without quietly widening scope.
Question 3 / 11 · data
How should user data be stored?
See what's missing before you build
Two lists — what you've locked in and what's still open — tell you exactly what's underspecified. Fix anything in one click, or skip it for now.
Decisions
Locked
- ✓ Web app
- ✓ Email login
- ✓ Postgres
Still open
- • Payment provider
- • Offline sync
Refine, version & export in Studio
Read and refine any file with the buttons-only refine bar, plan a focused V2/V3 increment, see how the whole app connects in the Workflow view, then export the pack for your coding tool — copy, ZIP, or JSON.

What's inside
Specific tools, not vague promises.
App profile
Reads your idea and works out the type, users, data, and stack.
Adaptive questions
Idea-specific — only what's actually missing.
Locked & open decisions
See what's settled and what's still missing.
Blueprint
Tool-ready files for every major AI coding tool.
Studio refine
Describe a change in plain words and it routes to the right files — or edit any file by hand, free.
Version planning
One blueprint becomes many — a focused V2, V3… built on the last.
Roadmap & specs
See what your app is made of and what it is.
Workflow view
How your app works, end to end — every screen, server step, data store and outside service, connected. No AI, no credits.
MCP setup center
Ready-to-copy MCP and local-model setup for the coding tool you build with — generated locally, nothing installed for you.
Local-first by design
Your idea, answers, and blueprints live in your browser on this device by default. Sign in only when you want AI generation and cross-device sync — and Delete all data in Settings clears this browser anytime.
AI only when you ask
AI runs only on a deliberate action — plan, generate, refine. Nothing happens in the background, and browsing, reviewing, and exporting your blueprint never spend your AI allowance.
