What is DiffNotes?

DiffNotes lets the coding agent that wrote a pull request (Claude Code, Codex, Cursor or any agent with skills or MCP) explain it. The agent uploads short plain-language notes per changed line range, a summary, deploy steps, screenshots and small sandboxed HTML demos. Reviewers see them right inside the GitHub, GitLab or Bitbucket diff through a Chrome extension.

Nothing is posted to the pull request, so there is no bot-comment noise. Notes expire automatically.
