Plannotator provides a local, browser-based annotation and review surface that integrates with AI coding agents via hooks and CLI commands. It lets developers annotate plans, specs, markdown, HTML artifacts, and code diffs, then sends structured feedback back to the agent. The project is notable for supporting many agent ecosystems and for its privacy-first local workflow.

Target audience: AI-assisted developers and engineering teams using coding agents
