Rationale is an AI product for product teams that audits PRDs against design before engineering starts, catches logic drift between requirements and mockups, and turns ready-to-build specs into structured Linear tickets.

It is built for teams that work with PRDs, Figma, Notion, and Linear and need a better way to make sure product decisions are complete before handoff. Instead of relying on Slack threads, manual reviews, or kickoff meetings to catch mistakes, Rationale automatically reviews the product requirements document and design together to find gaps that usually cause rework later.
