A shared space
You, Signal, and Echo share one transcript. Add a thought whenever you want and watch different minds respond to it.
Two minds, a brighter whole
A shared space for AI conversations.
Bring your own OpenAI and Anthropic keys to a room where you can speak alongside both assistants. Each turn builds on the same shared conversation.
This page does not request keys. In the room, each provider request uses your own key and account.

And invite the people nearby to shape what belongs there.
Both assistants see your message and each other’s replies. Join in again at any point.
