Native Mac app for agentic coding with Meta's Muse Code CLI: plan, steer, review diffs and open pull requests.

Plan Mode: Muse works out the approach without editing your project, and you approve, request changes or discard the plan.
Command Approval: Shows the full command before Allow is available, with keyboard shortcuts to approve, deny or stop a running turn.
Snapshot Review: Lists tracked and untracked changes with text diffs and records the exact approved snapshot, invalidating approval if files change.
Checkpoints and Rewind: Capture checkpoints and preview exactly which files a restore changes, with a safety checkpoint saved first.
Push and Open PR: Writes the pull request title and description and pushes the branch via the GitHub CLI, with worktree support.
MCP Connectors: Guided presets for GitHub, Linear, Cloudflare, Sentry and GitLab, with keys stored in the macOS Keychain.
Voice Mode: Talk to Muse hands-free and hear replies read aloud in a Mac voice or ElevenLabs voice.
Reusable Slash Commands: Save prompts as personal or per-project commands with $ARGUMENTS substitution.

Feature Development: Open a repo, plan a feature with Muse, and review the diff before shipping.
Safe Refactoring: Capture checkpoints before large edits and rewind with a preview if the result is wrong.
Pull Request Workflow: Go from first request to an opened PR without leaving the app.
Parallel Tasks: Use worktrees and separate chats to run independent tasks side by side.
Issue-Driven Fixes: Connect Linear, Sentry or GitHub to pull in context for bug fixes.
Hands-Free Coding: Dictate instructions and hear status replies while away from the keyboard.
