AI companions

AI companions people come back to, built responsibly.

Characters, coaches and assistants with memory, personality and a voice. We build the conversation engine, the memory and the safety layer, so your product feels personal without putting users at risk.

What we build

Personal, consistent and safe.

A companion is judged on whether it remembers you, sounds like itself and never crosses a line. We build for all three.

  • Persona design with a consistent voice and personality
  • Long-term memory that users can see and delete
  • Real-time voice conversation
  • Content moderation and age-appropriate modes
  • Crisis detection that points people to real help
  • Analytics on engagement and conversation quality

People can see what the companion remembers and delete it.

Honest about being AI

The companion never pretends to be a person.

FAQ

Straight answers.

Anything else? Ask us on the audit call, or just email.

Which models power it?

Whatever fits: a frontier API, a fine-tuned open model for a specific persona, or a mix of both to keep costs down.

How do you protect vulnerable users?

With age-appropriate modes, moderation, and crisis detection that points people to real helplines. We also recommend a person reviews flagged conversations.

Can it talk?

Yes. It can hold a real-time voice conversation, and a custom voice is built only with the voice actor's consent.

How do you keep costs down at scale?

We summarise memory, cache answers, and send simple turns to smaller models.
