Multiplayer AI for engineering teams.

Your coding agent, shared with your team.

Mirahas entered the chat.

Share a join code and whoever is awake picks up exactly where the last person stopped, with the same context, files and history. Nobody explains the problem to the agent twice.

Built for more than one person.

The agent, the files and the permissions are all shared. Everything below is enforced on the server, not suggested by the client.
