A dashboard review assistant. Give it a dashboard's context and charts, and it checks the KPI hierarchy, narrative flow, chart choices, and UX governance against data-viz best practices — then returns specific, severity-rated feedback.

It came out of a real project. On a data-heavy product I kept running the same review by hand: is the right metric up front? does this chart earn its place? I turned that checklist into a tool, used it, then made it public and open-source.

Give it your dashboard's context and charts, and it returns specific, severity-rated feedback. Entirely vibe coded with Claude Code — no framework, no build step, one self-contained file. Bring your own API key; it runs in your browser, nothing is saved to a server, nothing is tracked.

Shipping's still in progress — it'll be live right here soon. Be patient, I'm a designer, not a dev :)
