README

DiffReview

Native macOS code review for the agent era. Run `diffreview .` in a Git project and the window **is** the diff: every change on your branch as one scrolling document. Read it like a pull request — check files off as reviewed, comment on lines — then copy the whole review as a single prompt-ready block for your coding agent.

Built with SwiftUI + AppKit (no Electron, no web view), packaged as a real `.app`, launched by a thin `diffreview` command — like `code .`, but native.

Features

The diff is the window — every file changed by the branch and working tree, one scrolling document against the merge base. Unified or split (old | new) layout with locked scrolling and a draggable divider; a line-number gutter shows real file line numbers with +/− markers.
Review like GitHub — sticky per-file header bars with change stats, a collapse chevron, and a [ ] Reviewed checkbox that folds the file away. Collapse state and your reading position persist per repo + branch, so a review survives relaunches.
Comments become a prompt — select lines and press ⌘K: a glass composer opens inline under the selection. Comments collect in a side panel, jump back to their code on click, and Copy exports the entire review as one block ready to paste into Claude Code or any coding agent.
Hunk-by-hunk navigation — ⌥⌘↓ / ⌥⌘↑ step through changes at GitHub's granularity (one stop per hunk), with a "Change 3 of 41" toast.
Per-commit scope — a toolbar picker re-scopes the document to a single commit's diff, or back to all branch changes.
The branch's PR, one click away — when the GitHub CLI (gh) resolves a pull request for the reviewed branch, a #123 toolbar button opens it in your browser (and flags Draft / Merged / Closed states). No gh, no PR: no button.
Many PRs, one window — diffreview a second project (or drop its folder on the Dock icon) and it attaches to the running window as
