Multiple people can use the same Cogitator instance. When someone teaches the agent something useful, everyone benefits. But personal things stay personal. Each person controls what's shared and what's private.
The alternative is everyone running their own AI, repeating the same information over and over. Or one shared account where nobody has any privacy. Neither option works well.
Invite codes let you add people to your Cogitator instance. Each person gets a separate account with their own conversations and tasks. Your chat history is yours. Theirs is theirs.
Standard conversations produce shared memories. If you tell the agent you're moving to a new house, everyone on the instance can benefit from that context. Private chats stay completely private. You choose which mode to use, conversation by conversation.
If a person leaves the instance, their private data goes with them. But things they contributed to the group remain. The household doesn't lose context just because someone moved on.
Three levels: admin, moderator, and user. Admins manage the instance. Moderators can invite people and manage shared content. Users interact with the agent and contribute knowledge.
Each person's usage is tracked separately. You can see who's using what, how often, and how much it costs. No surprises on the bill.
No open registration. You add people by generating invite codes and sharing them directly. You control who has access at all times.
Any conversation can be marked private. The agent still uses its full capabilities, but nothing from that chat enters the shared knowledge base. Your journal entries, health questions, and personal notes stay yours.
