What is Plannotator?

Editorial review
Plannotator is an interactive tool designed to enhance the collaboration and feedback loop when working with AI coding agents. It provides a visual user interface for annotating and refining agent-generated plans and code diffs. This allows developers to mark up specific sections, provide inline feedback, and approve or deny agent proposals, streamlining the development process. The tool integrates seamlessly with popular AI coding agents like Claude Code, Copilot CLI, Gemini CLI, OpenCode, Pi, and Codex. Beyond individual review, Plannotator facilitates team collaboration by allowing users to share annotated plans and feedback with colleagues. This shared feedback can then be directly imported and sent back to the AI agent, enabling iterative refinement. The platform prioritizes privacy and security, offering end-to-end encryption for shared plans and zero-knowledge storage, ensuring sensitive information remains protected. It's fully open-source and self-hostable, providing flexibility and control to its users.
