Rationale is an AI workspace for product teams. You bring your Figma designs and PRD together in one place, and Rationale audits the gap between what was specced and what was designed — surfacing missing states, edge cases, and contradictions before they become engineering surprises. When everything checks out, export a clean handoff doc in one click.Documentation Index

Integrations
Connect Figma, Notion, Linear, and Slack to your workspace.
How Rationale works
Rationale gives product teams three ways to work, depending on where you are in the process:Bring your sources
Import your designs from Figma and your spec from Notion, a file upload, or a URL. Rationale reads both.
Run an audit
Rationale cross-references your PRD text against your Figma screens pixel by pixel, flagging gaps, missing logic, edge cases, and contradictions in plain language.
Act on findings
Accept or dismiss each finding. Push confirmed gaps to Linear as issues, leave comments in Figma, or send a summary to Slack.
Pick your workflow
Watch for drift
Link a Figma file and a PRD. Rationale re-audits every time Figma is saved.
Designs → PRD
Drop a Figma file and let Rationale write the requirements doc for you.
PRD → Brief
Paste your spec and get a screen-by-screen design brief, ready for your designer.
