Long-form on critique quality, the loop from idea to proposal, and what makes a PRD actually useful.
How to Write a PRD (That Survives Review)
How to write a PRD step by step, then write it so it survives review: the sections, the process, and the gaps a senior PM catches before engineering does.

CraftA fair, dated comparison of AI PRD review tools (Thinkr, ChatPRD, PMPrompt, Centercode) on the one thing that matters: does it publish its review rubric?

CraftCan AI review a PRD? Yes, and it is a different job than writing one. What it catches reliably, what it cannot, and whether it is safe to paste your spec.
