# plannotator > Visual review and annotation tool for AI coding agents Plannotator is a local, browser-based review tool for AI coding agents such as Claude Code, Codex, and Copilot CLI. It intercepts agent plans, diffs, specs, and HTML artifacts, opening an interactive review surface to mark up comments and send structured feedback directly back to the agent. It runs via a local CLI binary integrated with agent hooks or plugins. - Source: https://github.com/backnotprop/plannotator - Homepage: https://plannotator.ai - Live demo: https://room.plannotator.ai/ - License: Apache-2.0 - Built with: TypeScript 94.7%, CSS 2.3%, Other 3.0% - Stars: 9744 - Forks: 728 - Contributors: 181 - Last commit: 2026-10-29 - Latest release: v0.28.36 (2026-10-28) - Purpose: AI & LLM tooling, Agent skills, Developer tools, Coding assistants - Type: Web, CLI, Extension / plugin - For: Personal ## Worth score: 81/100 How much DigGitHub recommends it, from activity, adoption, docs, license and security signals. - Popularity: 20/25 - Momentum: 10/20 - Maintenance: 25/25 - Community: 11/15 - Readiness: 15/15 ## Downloads Latest release: [v0.28.36](https://github.com/backnotprop/plannotator/releases/tag/v0.28.36).
