Deciding together
Everyone sees which tools were called and what came back, so nobody has to take the conclusion on faith.
Group chat
More than one person. One conversation.
Most AI tools are strictly one-to-one: you and the assistant, in private, and everyone else gets told about it afterwards. Sigma Domain lets several people work in the same conversation at once.
- You
- Your colleague
- Your client
One live thread, with Claude working alongside all of you
How it works
Everyone sees the same thread
Invite people into a conversation and they join it live. Messages, tool calls and results appear for everyone as they happen — not as a transcript pasted in later, and not as separate sessions that have to be reconciled afterwards.
It changes what the assistant is for. Instead of each person running a private session and comparing notes, the work happens once, in front of the people who care about it, with the reasoning visible.
Handing work over
Bring someone into a conversation already underway. They get the context by reading it, not by being briefed.
Working with clients
Run a search or a comparison with the client present, and adjust it while they're watching instead of emailing revisions.
Afterwards
Sharing what came out of it
Conversations can be shared on their own — send someone the thread, a map you built in it, or a document it produced, without adding them to the session. What you share is what you chose to share; nothing else in your account travels with it.
A conversation isn't tied to the machine it started on either. Join from a laptop, continue on your phone, pick it up on the desktop app — the same live thread, mirrored across whatever you're signed in on.
