Cerne: Know Yourself

About this app

Cerne is a self-knowledge app. You talk about what is weighing on you, and it digs, in your own words, until what repeats comes to the surface. Then it turns that into something you can practice every day.

HOW IT WORKS

- Touch the area of your life that bothers you: work, money, relationships, family, body, purpose, or yourself.
- Choose a question, or write your own, and talk. Cerne asks and listens. It never lectures.
- Your own sentences become fragments. When two to four of them point the same way, Cerne proposes a layer: a conclusion built only from what you said, always shown with your quotes. You confirm it or reject it.
- When the layers close, you get your revelation: what was underneath, told back to you in text and voice, with a letter from your future self and a short daily practice.
- A monthly view of you: what repeats, your strongest sentence, your mood over the month, your revelations, your letters.
- A diary for the days between conversations.

WHAT CERNE IS NOT

Cerne is not therapy and does not replace professional care. It does not diagnose and does not give medical advice. If a conversation shows risk to your life, it stops and shows the crisis line of your country.

YOUR WORDS, YOUR CONTROL

- Nothing you write goes to an AI provider before you say it can. You are asked once, clearly, and you can withdraw in Settings.
- Your text is never used to train models, and the provider keeps it for at most 30 days, only for abuse checks.
- Every AI-generated piece is labeled, and every one can be flagged.
- Your material lives on your phone and in a private copy tied to your account. Export everything as a book, or delete your account and everything with it, from inside the app.
- No ads, no tracking, no selling of data.
