PRD Template for AI App Builders (Free Template + Example)

Garrett Pierson

A PRD — product requirements document — is a one-page plan that describes what your app does, who it’s for, and what “done” looks like, written before you build anything. Paste a good PRD into an AI app builder and it stops guessing. Ten sections, plain English, no jargon required. The template below takes about 30 minutes to fill in.

If you’ve opened Lovable or Claude Code, typed two excited sentences, and gotten back an app that’s almost right — wrong screens, features you never asked for, missing the one thing that mattered — the tool was working from a two-sentence brief. This page fixes the brief.

Why AI app builders need a PRD

AI builders fill every gap in your description with a guess. Tell one “build me a booking app” and it invents the user, the flow, the screens, and the rules. The guesses are statistically plausible, and they fit a generic booking app instead of your business. Then you spend days prompting the guesses back out, one by one.

A PRD closes the gaps up front. When the first prompt already says who the user is, what the three core features are, and what’s deliberately excluded, the builder’s first draft lands close enough that your vibe coding loop becomes refinement instead of rescue.

One thing to know before you copy a template off the internet: the PRD templates ranking on Google today come from Notion, Atlassian, Product School, and Figma, and they’re written for product managers briefing an engineering team — sprint fields, stakeholder sign-offs, OKR alignment. You’re one founder briefing an AI. You need the ten sections below and nothing else.

The template

Copy this straight into a doc, or download it as a markdown file. Markdown is the native language of AI tools, so you can paste the finished file directly into your builder.

# PRD: [Your App Name]

## 1. One-liner
[App name] helps [specific person] [get specific result] by [how].

## 2. The problem
- Who has this problem: [be specific]
- What they do today instead: [spreadsheet, texts, paper, nothing]
- Why that breaks: [what it costs them in time, money, or missed work]

## 3. The user
- Primary user: [who opens the app most days]
- Secondary user (if any): [their client, their staff, an admin]
- Technical comfort level: [phone-only? desktop? hates software?]

## 4. Core features (must-haves for v1)
1. [Feature] — [what the user does and what happens]
2. [Feature] — [...]
3. [Feature] — [...]

## 5. Later (explicitly NOT in v1)
- [Feature you're tempted to add — parked]

## 6. Key user flow
1. [User] opens the app and sees [what]
2. They tap [what] to [do what]
3. The app [does what]
4. They finish when [what result exists]

## 7. Screens
- [Screen name]: [what's on it, what the user does there]

## 8. Data the app stores
- [Thing]: [fields — e.g., Client: name, phone, notes]

## 9. Integrations & accounts
- Login: [email? Google? none for v1?]
- Payments: [Stripe? none for v1?]

## 10. Done means
- [ ] A real user can [complete the core flow] without your help
- [ ] [Specific, checkable result]

How to fill it in

Each section exists to remove one category of AI guessing. The ones founders skip are the ones that cost the most:

  1. One-liner. If you can’t fill in “[specific person] [specific result],” you have an idea problem. Run it through the 7 Key Criteria Scorecard before you write another word of the PRD.
  2. The problem. “What they do today instead” is the highest-value line in the document. It tells the AI what your app replaces, which shapes every screen.
  3. The user. “Technical comfort level” decides more design than any other line. An app for a phone-only contractor and an app for a desk-bound bookkeeper share zero layouts.
  4. Core features. Three to six, no more. Every feature you add widens the surface area where the build can go wrong.
  5. Later. The section that saves you. Writing a feature down as “parked” scratches the itch to add it without letting it bloat v1, and it tells the AI to stop helpfully building it.
  6. Key user flow. Write it like a story about one named person. “Maria opens the app and sees today’s appointments” beats “users can view appointments.”
  7. Screens. If you can’t name the screen, the AI will invent it.
  8. Data. List the nouns your business runs on (clients, jobs, invoices) plus the two or three fields each one needs.
  9. Integrations. The answer for v1 is usually “email login, no payments yet.” Say so, or you’ll get a half-built Stripe form you didn’t want.
  10. Done means. Checkable statements only: “a booking appears on the owner’s schedule instantly” passes the test, and “looks professional” fails it.

A filled-in example

Here’s the compressed version of a complete PRD for an imaginary founder: a mobile pet groomer who books everything by text today.

  • One-liner: GroomSlot helps solo mobile pet groomers fill their week by letting clients book and pay from a link.
  • Problem: Booking happens over text threads; double-bookings and no-shows cost her roughly a day of work each week.
  • User: The groomer (phone-only, checks it between appointments). Secondary: pet owners, who never make an account.
  • Core features: (1) Public booking page with her real availability. (2) Deposit payment at booking. (3) Automatic reminder the day before.
  • Later: Recurring appointments, staff accounts, a client app.
  • Done means: A stranger can book a Tuesday slot, the deposit lands, and the slot disappears from the public page.

Notice what the example does: it names one person, one costed problem, three features, and one checkable finish line. That’s a complete brief. The AI builder now knows what to build and what to refuse to build.

Using your PRD with Lovable, Claude Code, and the rest

The PRD is your first prompt. Paste the entire document into Lovable, Bolt, or Replit as the opening message, or drop the file into your project folder for Claude Code and reference it in every session. From then on, refinements get shorter because the context is already loaded. That’s the loop we walk through in how to build an app with AI.

Two habits that keep it working:

  • Update the PRD when you change your mind. The document is the source of truth. If a feature moves from “later” to “core,” edit sections 4 and 5 and re-share it; otherwise the AI is building from a brief you’ve silently abandoned.
  • Point disagreements back at section 10. When you’re not sure whether the app is finished, the answer is whichever boxes in “Done means” are still unchecked.

If you’d rather answer guided questions than fill in blanks, the AppBlueprint tool inside Software Secrets Studio asks you guided questions and generates the full package: a PRD, a system prompt for your builder, and a design prototype. There’s a free tier, so you can generate your first blueprint without paying anything.

What a PRD is not

  • It’s not frozen. A PRD is a living one-pager, and v1 of the document will be wrong somewhere. You’ll revise it several times during the build as real screens teach you what you meant. That’s the document working, so keep it one page — a plan you’ll update beats a spec you won’t reread.
  • It’s not validation. A beautifully specified app nobody wants is still an app nobody wants. The PRD assumes the idea already survived contact with real people. If yours hasn’t, spend two days on the 48-Hour Validation Sprint before you spend thirty minutes on the template.
  • It’s not a business plan. Pricing, finding customers, and getting paid live outside this document. The PRD gets you a product; how apps make money covers what happens next.

The bottom line

A one-page PRD is the cheapest time you’ll spend on your app: describe the user, the features, the flow, and what “done” means, and the AI builder’s first draft arrives close to right instead of close to generic. The template above is yours to copy. What it can’t give you is the rest of the journey: picking an idea worth specifying, building it, and turning it into income. That’s exactly what Software Secrets 2.0 covers, free.
