Use it as an everyday chat app; hand it a folder and it gets to work — reading code, editing files, running commands. It can also handle repetitive chores on a schedule, and you can keep chatting from your phone when you're away from your computer.
✨ Highlights
🗣️ All in Chat
Just say it in the chat: create a persona, set up a scheduled task, remember a habit, mount a folder… No digging through settings — click confirm and it's done.
🎭 Multiple personas, each with a specialty
Ships with Deva, an all-round assistant, and 小码酱 (Xiaomajiang), a security research expert. Create your own too — each with its own personality, avatar and preferred model.
🤖 Subagents, multi-agent dispatch
Big tasks get split up and dispatched to multiple subagents running in parallel — or in the background when the result isn't needed right away. Four built-in types — General, Explore, Research and Plan — each with its own context, returning only the conclusions.
⏪ Broke something? Roll it back
/rewind to before any turn. Code and conversation can be restored separately, and a rewind can itself be undone.
⏰ Scheduled tasks
Create a task with one sentence; it runs on time and notifies you when done. Supports daily, weekly, monthly and cron.
📱 Keep chatting in IM
Connect your favorite chat app. Away from your computer, messages from your phone go straight to Deva on your desktop.
