AI Prompt to Write a PRD for an AI App Builder
Most people ask AI to “write a spec for my app”—and wonder why the output is mediocre. Here's how to write a prompt that actually gets you what you want on the first try.

“write a spec for my app”
Too vague—AI has to guess what you want
“Write a concise product spec I can paste into an AI app builder (Lovable / Bolt / Replit) to build a v1. App idea: [one sentence]. Output these sections: (1) one-line purpose, (2) target user, (3) core entities with their fields and types, (4) the 3-4 screens and what each does, (5) the single most important user flow step by step, (6) what is explicitly out of scope for v1. Keep it under 400 words and concrete — no marketing language.”
Specific, clear, ready to use
What makes the strong prompt better?
Forces a data model and screen list — exactly what app builders need to avoid generic output
An explicit out-of-scope section stops the AI from over-building a bloated v1
Caps length and bans marketing language so the spec stays buildable, not a pitch deck
