Personality for AI

The models are smart.
We make them someone.

Snouper Ltd builds the personality layer for AI: the part that sits on top of a language model and decides who it is. How it talks, what it remembers, what mood it's in, and where it draws the line. Our first product, rizzher, is where we're testing it.

Five identical dark robots stand in a row. Four are rigid; the one in the middle wears a wool coat, legs crossed, hand in pocket, head tilted.

What we build

The model supplies the intelligence. Everything that makes it one consistent character has to be built around it.

Character

A voice you would know without a name on it. Its own taste and opinions, things it will not do, and a way of saying no that stays in character. Written once, and held in every reply.

  • Voice
  • Taste & Opinions
  • Boundaries
  • Staying in Character

Continuity

What you said on Monday comes back on Thursday. A mood that follows the conversation, a shared history that builds over the days, and replies that arrive at the pace of a person, not a server.

  • Memory
  • Mood
  • Shared History
  • Human Pacing

A prompt gives a model a role for one conversation. We're building what keeps it the same character on day thirty.

AI already answers from phones, cars and speakers. Robots are next, and how it behaves will matter as much as what it knows.

Personality is more than a prompt

A paragraph telling a model to be friendly lasts a few messages. Character that holds needs memory, state, timing and limits built around the model.

Agreeable is not the same as good

Most assistants are tuned to agree. Someone worth talking to has their own taste, can disagree, and reacts to what you actually said.

The line is part of the character

What it will not do gets the same care as the voice. And when someone says they might hurt themselves, the game stops and it points them to real help.

Models change. The character shouldn't.

We keep the personality separate from the model underneath, so it can move to a better one without becoming someone else.

rizzher is our first attempt at all four.

Our first product

Practice on someone who reacts.

rizzher Texting practice. Not a girlfriend.

rizzher is an iPhone app for texting practice, before it counts. You text Mia. She answers like a real match would, warm when a message is good and flat when it's lazy, and a coach marks what landed, what fell flat, and what to send instead.

It's a hard test for a personality. Practice only works if Mia is believable: the same person every day, with her own taste, who remembers what you told her and isn't impressed by everything you say.
