Description
After Claude writes a big chunk of code you end up scrolling the diff in a terminal, copying line numbers and telling it line by line what to change, then repeating that a few times before you can merge. Diffity is a Mac app that turns this into a GitHub-style review: write a comment on any diff line, send it to Claude Code in one click, and the fix lands back in the same thread.
It is not limited to local changes. Open any commit, range or branch, or pull in a GitHub PR and post the review back as Comment, Approve or Request changes. Mention @claude in a thread to ask a question, or have Claude read the whole change and review it first. The AI features need a logged-in Claude Code and Node.js. MIT licensed, macOS 13.3 or later, Apple Silicon and Intel.
Inline comments to Claude:Comment on a diff line or any file line and send it to Claude Code to fix, with no copy-pasting of context.
@claude in threads:Ask a question in a comment thread and the answer appears right there.
Claude as reviewer:Have it read through the change and leave comments, then you pick which to accept.
Review anything:Single commits, commit ranges and whole branches, plus browsing and commenting on any file.
GitHub PRs:Load a PR and post the result as Comment, Approve or Request changes.
Fast navigation:⌘P and ⌘K to jump, ⌘1 to ⌘9 across projects in the side rail, and find across the whole diff.
Viewed tracking:Badges for files changed since you last looked, and a .diffityignore to hide the noise.
Display options:Split or unified view, light and dark themes, a colour-blind palette, and self-updating.
