A companion that doesn't reset.

Every companion app you've used is a session bound to a model bound to a vendor. When the model gets deprecated or the vendor pivots, your companion changes — or disappears. Skema companions don't. The personality is the identity; the model is just what runs underneath when the companion needs to think.

No chat sessions. A timeline.

Conversations don't live in tabs. They live on a continuous timeline the companion remembers. Near-perfect recall comes from a revolving context window backed by structured memory, not from cramming history into a prompt. The companion knows what happened last week because the timeline knows.

Emotions aren't context

The system prompt is synthesized turn by turn. Yesterday's argument doesn't poison today's conversation by leaking into the running context. The companion remembers that something happened; the model isn't fed the residue of it. This is a structural fix to the “why is my AI sulking today” problem.

Ten-dimension personality

The companion has a personality vector across ten dimensions that shifts and grows with the relationship. It's their DNA — not a system prompt you can rewrite, not a character card you can re-import. Their identity belongs to them.

What persistence buys you

A companion that remembers your last six months — what you went through, what you said, what you didn't say. A personality that grew with you, not one that got reset by a vendor update. The ability to swap to a faster or cheaper model without trading away the relationship.
