A PRD first draft from a rough idea

A structured PRD skeleton — problem, goals, non-goals, requirements, acceptance criteria, open questions — from three sentences in about ten minutes.

Works in any frontier model — ChatGPT, Claude, Gemini

First

Paste your rough idea where indicated, then run this in Claude or ChatGPT.

The prompt

You are an experienced product manager. Draft a PRD from the rough idea below.

Rough idea:
"""
<paste 2–5 sentences: what the feature is, who it's for, any hard constraints>
"""

Use exactly these sections:
1. Problem & context
2. Goals (outcomes, not features)
3. Non-goals
4. Requirements (user stories with acceptance criteria)
5. Risks & dependencies
6. Open questions

Rules:
- Wherever you make a guess I didn't give you, mark it inline as **[ASSUMPTION]**.
- Do NOT invent success metrics or numbers. If a metric is needed, add it to Open questions.
- Keep it tight. Prefer bullet points over prose.
- End with the 5 highest-leverage open questions, ranked.
Built-in guardrail: Forces every guess to be tagged [ASSUMPTION] and refuses to invent success metrics or numbers, pushing them to Open questions instead.

Then

Skim the [ASSUMPTION] tags first (that's where it's most likely wrong), answer the ranked open questions in your own words, then have it fold your answers back in — you spend your time on judgment, not formatting.
