 Browse your DAG, review side-by-side diffs, resolve conflicts, and run every jj operation from one window. JayJay is a full-featured **jj GUI** with DAG visualization, interdiff (PR-style revision comparison), diff edit mode, file annotate, one-click conflict resolution, AI-generated commit messages, and a command palette.

-The GPUI shell uses [Zed's GPUI 1.0](https://github.com/zed-industries/zed) and is **read-only today** — DAG, diffs, annotate, file history, evolog, FS-watcher auto-refresh, persistent file review (space to toggle, mtime-based invalidation), bookmark / workspace pickers.

+The GPUI shell uses [Zed's GPUI 1.0](https://github.com/zed-industries/zed). It has read parity for DAG, diffs, annotate, file history, evolog, FS-watcher auto-refresh, persistent file review, bookmark / workspace pickers, plus early write actions for describe and the commit box. More write actions are tracked in [Roadmap.md](Roadmap.md).
 
 **Auto-update**: JayJay checks for updates automatically via Sparkle. You can also check manually from JayJay → Check for Updates. Auto-update may require App Management permission in System Settings → Privacy & Security.
 
 **Requirements**: macOS 26 (Tahoe) recommended.

 JayJay is **free and source-available**, not OSI open source. The macOS app is [BSL 1.1](LICENSE) — free to use, fork, modify, and redistribute; the only restriction is paid app-store distribution without permission. It converts to Apache-2.0 on 2030-03-23. The Rust crates (`jayjay-core`, `jayjay-uniffi`, `jj-diff`) are Apache-2.0 today.

-The shipped SwiftUI app is macOS-only. A second cross-platform shell built on Zed's [GPUI](https://github.com/zed-industries/zed) framework is in alpha — it shares the Rust core (`jayjay-core`) with the SwiftUI shell and is read-only today (DAG, diffs, annotate, file history, evolog, FS-watcher auto-refresh, persistent file review). Build it with `just gpui` from a source checkout. Write actions land in the next milestone; see [Roadmap.md](Roadmap.md).
