About Diffsmith
Diffsmith is a code review studio for local git changes produced by AI coding agents such as Claude Code, Cursor, Codex, or Copilot. It loads the uncommitted diff from a repository and lets you click any line to leave anchored comments, then hand the feedback back to the agent. The tool works fully offline and is purchased once for lifetime access.
Review
Diffsmith entered the developer tools scene this week as a focused utility for inspecting and annotating AI-generated diffs. Rather than a general-purpose code review platform, it targets the specific loop of reviewing agent output and feeding notes back to the agent. The following sections break down its capabilities, limitations, and how it fits into a developer's workflow.
Key Features
- Open a local git repository and view the uncommitted diff generated by an AI coding agent.
- Click any line in the diff to leave a comment anchored to that exact code location.
- Archive comments
