AI App Blueprint Free
Free template + Claude skill · 45 minutes

Plan your app in 45 minutes. Then make AI build exactly that.

The AI App Blueprint is a plain-English plan you fill out before you prompt. It gives Claude, Lovable, Bolt or Cursor a fixed scope, numbered features and a finish line, so you stop getting surprise features and start shipping.

The problem

Why AI builds go sideways, and what the blueprint does about it

01

You describe it loosely. It builds it loosely.

The fix: five short sections give the AI your idea, your user and the exact path they take, in one paste.

02

It keeps adding things you never asked for.

The fix: a "Not in version 1" list the AI is told never to touch, plus a hard cap of seven Must-haves.

03

Every session starts from zero.

The fix: feature IDs. "Build CO-2 next" replaces a paragraph of re-explaining your app.

What's inside

Two ways to build your plan. Both free.

Option A · Fill it in yourself ~45 min

The Blueprint

Ten fill-in sections with a worked example in every one, a 60-second quality check and a copy-paste hand-off prompt for your AI builder. Edit it online or download it as a PDF or Word file.

10 sections Worked example Quality check Hand-off prompt
Option B · Get interviewed ~20 min

The Claude skill

Install it in Claude once. Then say "I have an app idea." Claude asks a few questions at a time, proposes your feature list, keeps version 1 small and hands you the finished blueprint.

The runbook

Seven steps from blank page to first prompt

Follow these in order the first time. Total time: about 45 minutes, most of it in steps 3 and 4.

  1. 012 min

    Make your copy

    Open the blueprint and make it yours: edit it online, or download it as a PDF or Word file. Keep it somewhere easy to find. You'll paste it into your AI builder more than once.

  2. 025 min

    Skim the worked example

    Every section is pre-filled for PawPlan, a booking app for a solo dog walker. Read it once, top to bottom. It shows you how much detail is enough, and it's less than you think.

  3. 0315 min · Sections 1–5

    Describe the idea

    Write your pitch, the pain you're solving, what your app will and won't do, who uses it, and the step-by-step path a user takes to get value. Start with the one-sentence pitch:

    It helps [who] do [what] so they can [result].

    Can't finish that sentence? Sharpen the idea before you build it. That's the blueprint already saving you time.

  4. 0415 min · Sections 6–7

    List your features, then fence them in

    Give every feature an ID, one sentence, the screen it lives on and a priority. Keep Must-haves to seven or fewer. Then list at least three things that are Not in version 1. That list is what stops the AI from wandering.

    Set the ground rules

    Tick the security, speed and privacy rules you want. Pick your tools, or write "Recommend for me" and let the AI explain its choice. Then choose three numbers that tell you it's working. Not sure? The defaults are safe.

  6. 061 min

    Run the 60-second check

    Eight boxes at the end of the blueprint. Every box you leave unchecked is a question the AI will answer by guessing.

  7. 072 min

    Hand it to your AI

    Paste the hand-off prompt, then your blueprint, into your AI builder. It plans Phase 1 and waits for your OK. From there, build one feature ID at a time.

    Your next prompt Build CO-2 next. Don't change anything outside CO-2.

After the hand-off

Three prompts that keep the build on track

Use these whenever the AI starts drifting. They all point back to your blueprint, so you never have to re-explain the app.

To stay focused
Build CO-2 next. Don't change anything outside CO-2.
To check quality
Check what you just built against the Ground Rules in Section 8 and fix anything that fails.
To catch drift
Compare the app to my blueprint. List anything you built that isn't in it, and anything in it you haven't built.
Option B, set up

Rather be interviewed? Install the skill in two minutes.

The skill produces the same blueprint as the template, so the runbook above still applies from step 6 onward.

  1. 1Download app-blueprint.zip. Don't unzip it.
  2. 2In Claude, open Settings, find the Skills section, and upload the zip. In Claude Code, unzip it into your skills folder instead.
  3. 3Start a new chat and say: "I have an app idea. Help me build the blueprint."
FAQ

Quick answers

Do I need to know how to code?

No. The blueprint is written in plain English. Your AI builder handles the code; the blueprint handles the thinking.

Which AI builders does it work with?

Any tool you can paste text into: Claude, Lovable, Bolt, Cursor, Replit, v0 and others.

What's a PRD?

A Product Requirements Document, the plan professional product teams write before building. This is a beginner-friendly version with the jargon removed.
