Key Features
Time Traveling
Revert code, chat, or both, independently. Undo a single file change or roll back an entire conversation. Every step is checkpointed with shadow git.
Profiles
Configure any of 36 providers. Switch between them instantly, even mid-task. Each profile stores its own API key, model, and settings.
Auto-Approval
Set approval rules per category, reads, writes, commands, plan changes. Control exactly how much autonomy the agent gets.
Artifacts
Real-time panel tracking every file change with git-style diffs. See insertions, deletions, and total impact at a glance.
Worktrees & Forking
Run multiple tasks in parallel, in worktrees or separate tabs. Fork any conversation to explore alternatives with a different profile.
