# Plannotator

> Interactive visual plan and code review tool for AI coding agents, with inline annotations, team sharing, and seamless integration with Claude Code, Copilot CLI, Gemini CLI, and more.

Plannotator is an open-source interactive UI for reviewing and annotating AI coding agent plans and code diffs. It opens in your browser when an agent finishes planning, letting you approve, reject, or annotate proposals with structured feedback that flows directly back into the agent loop. It supports team collaboration via zero-knowledge encrypted sharing and integrates with major AI coding agents including Claude Code, Copilot CLI, Gemini CLI, OpenCode, Pi, and Codex.

- **Visual Plan Review** — *Approve or deny agent plans with inline annotations; see exactly what changed when the agent revises a plan via automatic Plan Diff.*
- **Code Review** — *Use `/plannotator-review` to view git diffs or remote GitHub PRs, comment on specific lines, and send structured feedback back to the agent.*
- **Annotate Any File** — *Use `/plannotator-annotate <file|folder|url>` to annotate markdown, HTML, URLs, or entire folders and send feedback to your agent.*
- **Annotate Last Message** — *Use `/plannotator-last` to annotate the agent's most recent response and return structured feedback.*
- **Team Sharing** — *Share plans and annotations privately with colleagues; small plans are URL-encoded with no server involved, while large plans use AES-256-GCM end-to-end encryption with zero-knowledge storage and auto-deletion after 7 days.*
- **Multi-Agent Integration** — *Install via a single shell script on macOS/Linux/WSL or PowerShell on Windows; then add the plugin to Claude Code, Copilot CLI, Gemini CLI, OpenCode, Pi, or Codex.*
- **Ask AI & Agent Code Reviews** — *Built-in AI assistance lets you ask questions about code as you review, and request full agent-driven code reviews.*
- **Self-Hostable** — *The sharing backend is fully open source and can be self-hosted for complete data control.*
- **SLSA Provenance** — *Every released binary ships with a SHA256 sidecar and supports SLSA provenance verification from v0.17.2 onwards.*

To get started, run the install script (`curl -fsSL https://plannotator.ai/install.sh | bash` on macOS/Linux) and then add the plugin to your preferred AI coding agent. Plan review activates automatically when your agent enters plan mode.
