questions, briefly answered.
do you train on my data?+
No. Your sources and conversations stay in your workspace. The model sees only what's needed to answer the current turn.
which models do you support?+
OpenAI today. Anthropic and Mistral next. Self-hosters can point at any OpenAI-compatible endpoint.
can i self-host?+
Yes. Docker compose, Railway, Hetzner, Fly. Anywhere that runs Postgres and Node.
what about hallucinations?+
Helia answers from your sources when it has them. When it doesn't, it says so instead of guessing.
