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.

01

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.

02

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?

[A]Cloud database — synced across devices
[B]On-device only — private, offline
03

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
04

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.
