A design coach inside Figma: 12 cited UX checks — contrast, tap targets, type, spacing — with drawn evidence, one-click fixes, and a four-nudge limit per session. Every finding links to the uxspot.io page that explains the thinking. Free, open source (MIT), English & French, and fully offline — the manifest declares no network access.

uxspot.io is a free UX reference. Its MCP server lets any client (Claude, Cursor, Claude Code) answer UX questions straight from the source: define a glossary term, search the curriculum, read a checklist, browse the AI-x-UX tools directory, or deal a round of Spot Check, the daily vocab game. Eight read-only tools, one endpoint, no key, no account, and every answer cites a real uxspot.io URL instead of a hallucinated one. Copy-paste install for every major client.
