Overview

Annotate UI elements for AI agents - no code integration required

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
