01 / use

Chat, and reason like you

Plain chat for everyday use, plus Think mode: give it a situation and it predicts what you'd decide — grounded in your confirmed memories, preferences, decisions, and behaviours, with every claim traced to real evidence.

02 / training

You confirm what it learns

Nothing about you gets trusted automatically. Extracted memories, preferences, and decisions sit as pending candidates until you confirm them — and every correction and contradiction is tracked, never silently overwritten.

03 / system

Your keys, your data, your audit trail

Bring your own Anthropic or OpenAI key. Every login, every model call, every provider change is logged. Nothing leaves your own Postgres instance — this isn't a hosted product with your data as the business model.
