The guide

How to live
in Atreeum.

There is nothing to learn, only a rhythm to find. This page is that rhythm, made touchable — every example below is real, and yours to try.

01Write a thought

A thought becomes a star.

Open Atreeum, write whatever is here — a sentence is enough. When you finish, Atreeum quietly reads it, names its themes, and sets it into your map. Try it below.

Your first entryTry it
Write your own, or borrow a beginning:
A sentence is enough.
Your map, waiting for its first star.
Reading, gently…

In the app this takes about a second, happens with a private AI reading you fully control, and never interrupts you while you write.

02Explore your map

Wander a month of thoughts.

This is a living miniature of the map — seeded with a fictional month of entries. Move through it, tap any star to read the moment beneath it, and switch the lens to see the same life arranged three different ways.

On your iPhone the map breathes, connects related thoughts with quiet light, and grows for as long as you keep it. The center is always you.

03Speak instead

Some days, you'd rather just talk.

Atreeum listens two ways. A guided session walks with you, one gentle question at a time. Just talk is a real conversation — a companion who knows your journal, answers honestly, and remembers what matters. Either way, your words become the entry. Its words never do.

Two ways to be heardPlay each

Guided

A slow breath, then one question at a time. For when you want to be led.

Just talk

Talk like you would to a person. It responds, gently, and remembers.

When you're done, say so — or say goodbye. Your side of the conversation becomes a first-person entry you approve before it's saved.

04Read your reflection

Tap the center. It tells you the truth.

The star in the middle of the map is you. Tap it and Atreeum reflects your recent entries back — honestly. It won't fake cheerfulness over a hard week, and when things are heavy it reaches back for the real, brighter moments you have already written.

The reflection · three different weeks

Beyond single reflections, the Insights space keeps a longer read — your emotional cycles, what precedes the hard days, and the quiet progress you're actually making.

The colors of feeling

Every feeling has its own quiet color.

Each star is tinted by the emotion beneath the words — dignified, never alarming. Touch a feeling to see how it's held.

Calm

Settles into jade — the color of a slow morning.

05Make the page yours

A page that feels like paper.

Choose the paper, the hand you write in, and the lines beneath it. The same thought, in a form that feels like you. Compose one below.

Tuesday · 9:41 pm
The rain finally stopped this evening. I walked the long way home on purpose, and for once I wasn't in a hurry to be anywhere else.
06Draw the curtain

You command the AI. Truly.

Honesty needs privacy, so the controls are real, not buried. Mark any entry private and it is never sent for analysis. Or turn the AI off entirely — Atreeum stays a complete, beautiful journal without it. Try both switches.

A private entry

One thought, kept for your eyes only.

Mark as privateThis entry is never sent to the AI.

Something I'm not ready to say out loud yet, even to a quiet machine.

The master switch

All AI, off. The journal, whole.

AI insightsNothing you write leaves your device while off.
Theme reading on each entry
The center reflection
Insights & patterns
Spoken companion

Writing, the map, search, sync — everything else simply continues. Your words are never used to train AI models, in any mode.

And beneath every switch: Face ID at the door, entries end-to-end encrypted in your own iCloud, on servers we never see.

Open. Write. Reflect.
Close, feeling clearer.
The whole practice · a few quiet minutes
Quiet questions

Asked, gently answered.

No — and Atreeum will never suggest you should. There are no streaks, no daily goals, no "you missed a day." The map is patient. It's exactly as beautiful after a quiet month as after a busy one. Come back when you have something to set down.

You. Atreeum locks behind Face ID the moment you leave it, entries live on your device and sync end-to-end encrypted through your own iCloud, and we run no servers that hold your words. When insights are on, entries you allow are sent securely to Anthropic, our AI provider, to name their themes, always under your control, and your writing is never used to train AI models.

Then say it out loud instead. A guided session begins with a slow breath and asks one gentle question at a time; Just talk is simply a conversation. Or write a single honest sentence — "I don't know what to write" is itself a real entry, and the map will hold it like any other.

No. It's built to tell you the truth in a kind voice — to name the real pattern in what you actually wrote, not to paper over a hard week with cheerfulness. When things are heavy, it reaches back to genuine brighter moments from your own words, because they're true, not because they're pleasant.

If you invite it to. Opt in and Atreeum can quietly note your body's context, including heart rhythm around the moments you wrote, read from Apple Health on your device and shown as a soft ring, never a chart demanding attention. If you also let reflections consider your body, coarse heart bands and rounded daily context, never your heart readings, join the analysis that writes your reflection. It's a whisper of context, and it's entirely optional.

Atreeum is made for iPhone and iPad, with a Mac companion on its way. Your journal moves between your devices through your own encrypted iCloud, so it's always the same journal, wherever you sit down with it.

You know the way now.
The rest is practice.

Atreeum is on the App Store for iPhone and iPad. Free to start, with a 7-day trial of Plus.
