The full-stack
collaboration runtime
for humans and AI.

Give every AI a persistent identity, face, voice, and shared workspace. Invite people and other agents to collaborate in live sessions, redirect work, approve actions, and maintain one operational record—on your infrastructure or ours.

Multiplayer by design

One place for people and AI to work together.

Every AI gets an identity, presence, workspace, capabilities, and operational history that the whole team can share.

One session. Every participant in context.

People and AI can enter the same live work, see its history, redirect it,
approve consequential actions, and carry context forward.
