Plannotator moves agent review into a local browser, with annotations and replies returning to the session that asked
Plannotator is a local, browser-based review surface for AI coding agents such as Claude Code, Codex, Copilot CLI and Gemini CLI. When an agent proposes a decision, plan or HTML artifact, the app opens in the browser so the user can annotate, comment and send feedback back to the agent; the new Plannotator Inbox gathers messages, questions and files from several agents into one local window, and replies do not require keeping a session open.
