AI writes first drafts. You own the 'why' and the trade-offs. Always.

AI-Generated PRDs and Specs

TL;DR

  • AI can draft PRDs quickly. It'll give you structure and boilerplate. It won't give you the hard parts: prioritization, trade-offs, stakeholder alignment.
  • Use AI for scaffolding. You inject context, constraints, and decisions.
  • Never ship an AI-generated spec without editing. The gaps will bite you.

"Write me a PRD for a user dashboard." Five seconds later, you have 2,000 words. Looks professional. Reads fine. Is it right for your product? Your users? Your timeline? AI has no idea. That's your job.

What AI Does Well

Structure:

  • Problem statement, goals, success metrics, user stories, acceptance criteria, out of scope. AI knows the template.
  • Use it. Don't waste time reinventing format.

Drafting from context:

  • "We're building X for Y users. Here are the constraints." AI can expand that into sections.
  • It'll be generic. You'll need to replace placeholder content with real decisions.

Alternatives and options:

  • "What are 3 ways we could solve this?" AI generates options. You evaluate them against your context.
  • Useful for brainstorming. Not for deciding.

What AI Doesn't Do

Prioritization:

  • Why this now? Why not that? AI can't weigh your roadmap, your stakeholders, or your politics.
  • You write the "why now" section. Every time.

Trade-offs:

  • "We're choosing X over Y because Z." That's a judgment call. AI might suggest a trade-off. It doesn't own the consequence.
  • You own it. Document it.

Stakeholder reality:

  • Sales wants A. Engineering wants B. Legal said C. AI doesn't know your org.
  • The spec has to reflect negotiated reality. You do that negotiation.

Edge cases and "what could go wrong":

  • AI tends toward happy path. You need failure modes, rollback plans, and "if we're wrong" clauses.
  • Add those. AI won't.

The Workflow That Works

  1. Dump context into AI — Problem, users, constraints, what you've decided so far.
  2. Get a first draft — Structure, sections, placeholder content.
  3. Edit heavily — Replace placeholders with real decisions. Add the "why." Add the trade-offs. Add the risks.
  4. Socialize — Get feedback. Revise. AI doesn't attend the meeting.

Red Flags

  • Shipping a spec you didn't read end-to-end. Gaps and errors compound.
  • Letting AI decide scope. "Out of scope" is a product decision, not a completion.
  • Using the same prompt for everything. Different features need different depth. A small tweak vs. a new product deserve different specs.

Manual process. Repetitive tasks. Limited scale.

Do This Next

  1. Draft one PRD with AI — Give it context. Get the draft. Note what you had to add or fix. Build a personal "AI PRD checklist" from that.
  2. Compare — Take an old PRD you wrote by hand. Could AI have drafted it? What would you have had to add?
  3. Create a spec template — Sections you always need. Use AI to fill it, but define the sections yourself. You own the structure; AI fills the blanks.
