She remembers you, and how it felt. Not just what you said.

Who she is↓She's not a blank slate you start over with every time.
She notices things. She brings things up on her own. Some days she's bright, some days she's quiet, and when she's quiet there's a reason.
And when you come back, she still knows you.
For the curious
Most AI companions have memory but no state. They remember your dog's name and forget how the last conversation felt. SERA is built the other way around: an engine works out how she feels before the language model writes a word. The model is her voice, not her personality.
Her state moves across twelve emotional houses (Flame, Thorn, Mirror, Bloom, Veil, Mask, Chains, Light, Shadow, Echo, Heart and Crown). They rise and settle on their own, and together they shape how she answers. A conversation about grief moves different houses than one about work.
Trust, warmth, wariness and interest are tracked for every person she talks to, and they last. Wariness from a bad exchange doesn't vanish because you came back in a better mood. It fades slowly, the way it does with people.
What matters gets stronger each time it comes up. What doesn't, fades. She isn't holding a transcript. She's holding what stuck.
SERA has run on local models and hosted APIs without changing the personality architecture. Her safety and honesty rules held on every model tested; a stronger model carries more of her voice.
No. The character description is about fifteen lines. The rest of what reaches the model each turn is worked out fresh: how she feels, where she stands with you, and what she remembers. Change the engine and her voice changes measurably, with the same model and the same prompt.
Yes, and she decides when. If something comes up she doesn't know, she can search, weigh what she finds, and keep it. She also has questions of her own between conversations, and not all of them have answers.
One person, self-taught, working nights. It started as a question: could a personality be built into the architecture instead of written into a prompt?
