About

onUI adds a lightweight visual annotation layer to Chrome so you can mark UI issues directly on live pages and generate structured context for AI-assisted fixes.

What you can do:
Annotate single or multiple elements on any webpage without modifying app code
Add intent and severity metadata to each annotation
Export reports in compact, standard, detailed, or forensic formats
Keep annotations tab-scoped with per-tab on/off control
Sync with a local MCP bridge (onui-local) for agent workflows in Claude Code/Codex
Clear on copy

Why onUI:
No backend required for core workflow
Local-first annotation + reporting
Built for iterative UI debugging and AI pair-programming loops

Notes:
Chrome stable support
Some pages (like chrome:// URLs) are restricted by browser policy
Local MCP setup is optional and requires separate local configuration
