# Yankı

> Yankı mirrors your own words back, names what you appear to feel, and offers one small next step. It is a companion, not therapy, and it never invents a feeling you did not put there.

Yankı is an emotional check-in companion, not therapy, not a diagnosis, not a medical device.
Reflections are produced by Anthropic's Messages API with claude-haiku-4-5-20251001 under a JSON-only prompt;
crisis wording is decided by a rule list before the model is called.
