AI Assistant That Writes Product Specs for Product Managers

AI product manager that helps teams write PRDs, get coaching and work from product docs — built as a side project that grew into a business.

In plain English

ChatPRD helps product managers write product requirement documents faster. You chat about a feature, and it drafts a clear document your team can review. Companies and freelancers pay a monthly plan. The founder has written that the product reached six figures in yearly recurring revenue; that claim is hers, not a payment dashboard we can open. The AI drafts most of the writing, while the founder still improves the product and talks to customers.

Step-by-step setup

  2. Chat interface drafts a structured PRD from a short brief; user edits before sharing.
  3. Start cheap to learn, then raise prices for Pro and Teams seats.
  4. Grow through PM communities, podcasts and content about better product docs.

Overview

ChatPRD is an AI platform for product managers: write product docs, get coaching and work with team workflows. The founder launched it as a side project and grew it into a paid product used by thousands of PMs.

Operator: Claire Vo. Website: https://www.chatprd.ai/

Estimated split: about 80% of the work automated, 20% human.

Realistic income

On the ChatPRD first-year blog post, founder Claire Vo wrote that the product had thousands of paying users, six figures in revenue in the first six months, and six figures and growing in ARR, with strong month-over-month growth. Those figures are operator-reported, not independently verified on TrustMRR or a public processor dashboard. Aiolum grades the story C for that reason. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.

Risks

  • Notion, Linear and the big PM tools are adding AI writing for the same job.
  • Vague “six figures” is a range, not a precise MRR you can plan from.
  • Enterprise buyers expect security reviews (SOC 2 and similar) before they pay.
  • Startup cost is not disclosed.

*Income figures are illustrative ranges based on public pricing and typical outcomes reported by practitioners, not guarantees. Most new online businesses earn little or nothing at first. Not financial, legal or tax advice.
