About

A quiet space to speak

How the conversation works

You write freely. The AI listens, responds with empathy and care, and asks one thoughtful question at a time when it helps. There is no script to follow. No prejudice. No judgement. You decide where it goes.

Privacy and control

The AI behind philofi. runs in Switzerland (Azure, Switzerland North); the app itself is hosted in Frankfurt, EU. Your conversations are never used to train AI models and never used for advertising. Guest conversations stay in your browser session; paid accounts can save, rename or delete chats at any time.

Not a substitute for therapy

philofi. is a private AI conversation space, not therapy, coaching or clinical care. If you are in crisis, call 143 (Die Dargebotene Hand) or 144 in an emergency.

Prefer to talk to a person?

Behind philofi. is Tam Nguyen, psychologist (lic. phil., University of Bern), based in Zurich. If you ever want to continue a thought with a human, you can book a personal conversation with him through WeitSinn, a deeper sense of meaning. By video or in person.

Separate from philofi. No subscription needed. Your philofi. chats stay private; you decide what you share.
