    Plannotator

    Plannotator

    Annotate and review coding agent plans visually, share with your team

    Plannotator is an interactive plan review and annotation tool built to support AI coding agents, offering a visual UI for markup, refinement, and team collaboration around agent-generated plans. It allows developers to annotate proposed plans, sketches, and outlines from tools like Claude Code or OpenCode with pen tools, arrows, and highlighting, seamlessly capturing feedback that can be shared across teams or pushed back to agents. Plannotator integrates with diff views so reviewers can annotate changes line-by-line in git diffs, provide structured feedback, and navigate plans visually rather than through raw text alone. Users can attach and annotate images, save approved plan versions, and automatically export feedback into systems like Obsidian or Bear Notes for documentation purposes.
