Plannotator is a code review tool that enables visual annotation and collaborative feedback on coding agent plans and code diffs.
The tool addresses the challenge of reviewing and providing feedback on work generated by coding agents. It allows developers to annotate plans and diffs visually, then share these annotated reviews with team members and send feedback back to agents through a single-click interface. This workflow bridges the gap between agent-generated code and human oversight, making it easier to guide agent behavior and catch issues before they propagate.
Teams working with coding agents who need structured code review processes should consider this tool. It suits projects where multiple people need to evaluate agent output and provide coordinated feedback. The visual annotation approach makes it particularly valuable when reviewing complex diffs or multi-step agent plans that benefit from contextual notes and team discussion.
The project shows active development with regular commits across multiple areas of the codebase. Work spans frontend improvements, backend functionality, and integration features, indicating sustained effort to expand capabilities. The maintainers respond to issues and incorporate user feedback into the roadmap. Development activity demonstrates ongoing refinement of both core annotation features and the agent feedback loop.
