ENPTES

You don't need to know what you want.

Most people look for answers before understanding the questions. But somewhere inside you, what matters already exists. Let's find out together what's at your core.

Get the app See how it works

How it works

From what hurts to what you do about it, in six moves.

Cerne is a Brazilian word. It names the core of a tree, the center that holds everything else. People have one too. Cerne is a self-knowledge and practice journey to reach yours, and this is how it happens on the screen.

1

Tap the leaf that hurts.

Seven leaves on a tree, one for each area of life. Pick the subject that hurts the most and start there.

2

Pick a question, or write your own.

Each leaf has questions people actually ask themselves. You can also say it your way, typing or dictating. That question becomes the dig.

3

Talk, and get to know yourself.

Cerne asks the questions that make you reflect. As it gets to know you, it keeps your fragments, your own sentences, and gathers them into small conclusions that you confirm or correct. It never advises.

4

Say "that's it" and a layer closes.

Five layers under every question: fact, feeling, pattern, origin, desire. Each closes only when you confirm it. The rings fill from the outside in, because the deep ones take longer.

5

The revelation arrives.

When the fifth ring closes, Cerne says what you already knew, in two sentences made of your own material. You can listen to it, and right below it shows how it got there, layer by layer. It comes with an image and a sealed letter.

6

It becomes practice, one small ask a day.

Concrete asks, drawn from your fragments. Done is done, for good, and the leaf bears fruit. A widget keeps the ask on your home screen.

A real one

This is what a revelation looks like.

Not a mockup. This one was dug in Cerne by one of the people who built it, over four conversations, and it is here with his permission. Only the names were kept out.

work · The revelation

“Why did I cancel my lunch again?”

You do not cancel lunch for work urgency alone.

At seventeen, you learned to postpone your needs to support your family.

The arrival

It arrives when the fifth layer closes.

Two sentences, written from his own material, after four conversations about one question. Nothing in them that he had not said first.

You do not cancel lunch for work urgency alone. At seventeen, you learned to postpone your needs to support your family.

❚❚ listen

Listen

Read out loud, for eyes closed.

Every revelation has a voice. The ring fills as it plays, the words light up as they are said, and the app dims everything else.

How he got here

  1. fact what happened?

    Lunch becomes negotiable whenever work feels urgent.

    “I was busy working like there is no tomorrow. I don't prioritize myself.”

    “I have several things to deliver to my boss and postponing lunch seemed like a better idea.”

  2. feeling what did it stir?

    Postponing yourself leaves you tired and worried about everything.

    “Anxiety, urgency to provide for my family, and the urge to keep working. That is why I skip lunch all the time.”

    “Tiredness, and worried about everything.”

  3. pattern has it happened before?

    Providing for your parents keeps turning your own future into what gets postponed.

    “Every single need that I have needs to be postponed because I need to provide.”

    “This month, every time, because I need to pay my parents' bills.”

  4. origin who taught you that?

    At 17, becoming the provider made your own needs wait.

    “My dad left us. My brother was younger, my mom didn't have a job back then, so I needed to step up.”

    “I started working and providing for my family. Wasn't it obvious?”

  5. desire what did you want instead?

    You want security for everyone without surrendering your life to work.

    “I wish I could always provide for my parents, because I love them, but not in exchange of my life.”

    “Money for everybody, including me. A roof, food, and that's it.”

The proof

How it got here, layer by layer.

Each layer is a conclusion he confirmed with "that's it", shown with the sentences of his that produced it. Scroll the card to read all five.

The letter

A sealed letter from his future self.

It is born sealed with the revelation and opens once, with a ceremony that cannot be undone. The image of it healed sits at its center.

The practice

And then it becomes practice.

Small asks drawn from his words, checked off for good. He wrote the third one himself.

The one rule

Cerne never writes a sentence for you.

A fragment is a sentence you said, raw. A layer is a conclusion the app writes from two to four fragments, always shown with the quotes behind it, and it only closes when you say "that's it". No conclusion from one sentence, no advice, no diagnosis. If it is not in your words, it is not in your revelation.

What you get

Get to know the app, and see how you can get to know yourself.

The treeSeven leaves on a tree, one for each area of life. Pick the subject that hurts the most and start there.
The leafYou do not need the right question. Pick one that comes close, or write your own, and the subject stops being vague.
The digBeing asked is not the same as being told. One question at a time, and what you said stays in your words.
The layersThe same question, five times deeper. The outer rings fill fast. The inner ones ask for honesty you do not have on day one.
The revelationWhat you already knew, said back in a way you cannot unsee. Made only of things you said first.
The practiceKnowing changes nothing on its own. One small thing a day, small enough that you actually do it.
YouA month of you, seen from a distance: what you revealed, how you felt, and what keeps coming back.
The diarySomewhere to put what is on your mind before it becomes anything. When a subject keeps returning, it becomes a dig.

Your material

The most intimate text there is. Treated like it.

Everything you write lives on your device first. Here is what leaves it, and what never does.

  • Your device is the source of truthConversations, layers, revelations and diary are stored on your phone. A protected copy exists only so you can change devices.
  • Explicit permission before the modelBefore the first conversation, the app asks. You can say no, and the rest of the app keeps working.
  • Your text trains no modelThe route never passes through a provider that trains on or collects your text. The provider keeps it up to 30 days for abuse checks, then deletes it.
  • No ads, nothing soldNo tracking across apps or sites. What we measure is counts, never sentences.
  • Export everythingA PDF book, the conversations in plain text, the images and the voices. Portability is a button, not a request.
  • Delete your accountFrom inside the app, with 30 days to change your mind. After that, gone for real, including the copy.

Questions

Before you download

Is Cerne therapy?
No. Cerne is a self-knowledge and practice journey. It does not diagnose, does not advise and does not replace a professional. If what you are feeling is bigger than this, look for a psychologist, or call your local crisis line.
Which phones does it run on?
iOS (iPhone) and Android. The iOS app comes first; the Android app follows. The site will show the store links the day each one is live.
How much does it cost?
You can try it free for 3 days. After that it is a subscription, monthly or yearly, managed by the App Store or Google Play. What you dug and revealed stays yours if you stop.
Does the app write things for me?
It writes layers and revelations, and only from your own sentences, always shown with the quotes behind them. It never writes a fragment for you: a fragment is your raw sentence, and nothing else.
Which languages?
English, Portuguese (Brazil) and Spanish. The conversation happens in the language you write in.
Where does my text go?
Your text lives on your device. When you chat, the text goes through the Cerne server (which only forwards it) to a language model that does not train on it and keeps it at most 30 days. You give explicit permission before the first conversation, and can withdraw it in Settings.

Find out what is at your core.

One leaf, one question, and what you already knew, seen from a new angle and told back to you in your own words.
