Nice to have
Avoid for now
- Generated PRDs treated as validated strategy before customers, engineering, and constraints are reviewed.
- Putting fundraising, unreleased roadmap, customer commitments, or sales notes into unapproved personal AI accounts.
- Buying several assistant seats before the founder knows whether drafting, research, or team handoff is the recurring bottleneck.
Budget notes
- Start with one paid general assistant only after a free or individual trial improves a real PRD draft.
- Keep Notion AI in the stack only if Notion is already where product decisions and specs live.
Privacy and admin notes
- Treat roadmap plans, customer feedback, pricing ideas, and fundraising context as sensitive company material.
- Keep the final PRD, requirements, owner decisions, and source links in the workspace of record rather than only in chat history.
Rollout next step
Pick one upcoming product decision, gather existing customer notes and constraints, draft a short PRD with Claude, use ChatGPT for objections and stakeholder summaries, then move the reviewed version into Notion with source links attached.
