You don't need separate accounts or separate installations. Multiple people share one Cogitator instance. Everyone gets their own conversations, their own tasks, their own private space. But the shared knowledge benefits the whole group.
Running a personal AI for each person in a household or team means duplicate setup, duplicate costs, and no shared context. If you teach the agent something useful, nobody else benefits.
The admin creates invite codes. Each person signs up with their own username and password. No open registration, no external accounts needed. You control exactly who has access.
Each user has their own conversations, tasks, and private memories. Shared memories are visible to everyone. You choose what stays personal and what goes into the common pool.
The admin manages users and settings. Everyone else has their own workspace. Usage is tracked per person so you can see what costs what and who's using the agent most.
Each person has their own chat history and active conversations. Your chats are yours. Other users can't see them.
Your scheduled tasks are yours. They don't show up in someone else's dashboard. Each person manages their own automations independently.
The admin sees everyone's usage. Individuals see their own. You know exactly how much each person is using the shared AI and what it costs.
Private memories are truly private, not just hidden. The system enforces separation at the data level, so there's no accidental leakage between users.
