Example · Learning
Language practice partner
A patient conversation partner that remembers your level and the mistakes you keep making.
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

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.
