About this project

AI PRDs are different from normal PRDs in three ways: you must scope LLM capabilities (hallucination, latency, cost), you must define evals before launch, and you must plan for messy probabilistic UX. Pick a real product you know deeply and write a 3-5 page PRD for adding one specific AI feature. The PRD is the portfolio piece; get a real PM or AI engineer to critique it.

Why build this in 2026?

AI PRD writing is the most common interview asks for AI PM roles. Most PMs cannot produce a defensible one.

What you'll ship

  • PRD document (3-5 pages)
Eval plan as a separate section
