A local Git diff viewer/GUI for reviewing and commenting on AI-generated code, designed for human-in-the-loop workflows.
AI coding agents generate code fast—but humans still need to review it. DiffClaw gives you a native macOS app to review git diffs, add inline comments, and export feedback in a format AI agents can read.
- 100% Local — No accounts, no cloud, no network. Your code stays on your machine.
- Built for AI Workflows — Export comments to markdown that AI agents can process.
- Native macOS — Fast, lightweight SwiftUI app with GitHub-style dark theme.
- GitHub-style Diff Viewer — Dark theme with syntax-colored additions/deletions
- Inline Comments — Click any line to add review feedback
- Multi-Tab Support — Review multiple repositories simultaneously
- One-Click Export — Generate
.diffclaw-review.mdfor AI agents - Live Refresh — See latest uncommitted changes with Cmd+R
