A private journal that stays yours

Cozy keeps your journal on your own device, as plain files you can open with anything. There's no Cozy server, and nothing is fed to AI.

Fuji at first light

Set an alarm for 4:20 and almost talked myself out of it. So glad I didn't.

The lake was perfectly still. Fuji doubled in the water like the mountain couldn't quite believe itself either. A few other people stood along the shore, all of us quiet, all of us holding our breath a little.

I've seen this view on a hundred postcards. None of them tell you how cold the air is, or how the pink creeps down the snow so slowly you don't notice until it's gone. Best morning of the trip, easily.

No one reads your diary. Not me, and not an AI.

I built Cozy because I wanted a private place to write, not another app offering to do something clever with what I put into it.

I won't train anything on your diary

There's no chat window, no summary of your year, no assistant offering to look through what you wrote. Nothing you write in Cozy is scraped, read, or sent off to a model, mine or anybody else's. There's nowhere for it to go.

I never see a word of it

There's no mystery cloud. Your journal lives right where you write it, on your own device. No server to breach, no account to lock you out, no stranger who can open your diary.

What can you find in Cozy?

Your files, on your computer

Every entry is a file in a folder you pick. Open them with any app. They stay readable without Cozy.

More than text

You can add a photo or several, an audio file, or a video, whether it lives on your computer or comes from YouTube. Drop in whatever made your day so you can find it again later.

Make it yours

Tag your entries, mark where you were, or build your own trackers for any habit or thing you want to follow. Cozy bends to the way you like to journal.

A quiet place to write

Slip into a full-screen writing mode with soft sound in the background: rain, a forest, a cafรฉ. Little touches that help you settle in and keep going.

Different ways to look back

See your entries laid out on a calendar, or pinned to the places you wrote them. However you remember, Cozy helps you find your way back.

Write in any language

Your journal speaks whatever language you do. Write in Japanese, Arabic, or Spanish, mix a few in one entry, and the languages that read right to left flow that way on their own.

A password on the private ones

Lock a journal and Cozy asks for its password before it opens. Until then it stays out of search and out of your other journals, and it locks again when you put the app away. On iPhone, Face ID opens it in a glance.

Already journaling somewhere?

Moving from another app shouldn't mean starting over. Cozy brings your old entries in from Notion, Day One, Obsidian, and Bear, so you keep your whole history instead of a blank page.

What early users are saying

“After using Day One for 15 years, I've made the jump to another journaling appโ€ฆ The never ending push to upgrade, AI inclusion and lack of quality updates is just too much. I've moved to Cozy and I'm really enjoying it. Cozy is lightweight, actively being worked onโ€ฆ I had some issues with the import feature and the developer was very responsive, even releasing a fix that same day.”

“I was a Day One user, but woke up one morning to them encouraging me to use AI to โ€˜interrogateโ€™ my journal. Nope. That sent me looking for an alternative. I really like Cozy so far! It's clean, it's easy to use, my Day One entries zipped right into it. Thank you!”
via email
“I'm loving Cozy so far and can't wait to try out the iPhone app as well when it's ready. Everything is working really well and it is a great writing experience in the app, very enjoyable to use.”
via email
“I've been using it for a week and I do not regret the purchase at all! :) Very solid, intuitive and aesthetic. I synced with two of my computers to be able to access it from bed, which is where I like to do my digital journaling, and works like a charm. I hope your app continues to grow!”

Where your journal lives

Your journal is a folder on your computer. Where you put it decides where it goes.

On one computer
Pick a folder and start writing. Time Machine or File History backs it up with everything else.
On several computers
Put the journal in iCloud Drive, Dropbox, or any folder that syncs. Every computer opens the same journal.
On your iPhone or iPad
Keep the journal in iCloud Drive. It's the only folder iOS lets an app read, so that's where your phone and your computer meet.

Frequently Asked Questions

Does it use AI?

No, and it never will. Your entries are regular files on your computer. If you ever want to use an AI tool with them, you can, on your own terms. Read more about why.

Can anyone else read my journal?

Not inside Cozy, if you lock the journal. On iPhone, Face ID opens it. The files underneath stay plain on your disk, so anyone who can log in to your computer can open the folder. Cozy doesn't encrypt them on purpose: your operating system does it better. Turn on FileVault or BitLocker and the journal is locked with the rest of your disk. On iPhone and iPad, iOS encrypts what Cozy writes behind your passcode. There's no password reset: forget it and Cozy can't open that journal again.

Can I sync between devices?

Yes, through the folder: iCloud Drive or Dropbox between computers, iCloud Drive with iPhone or iPad. Cozy has no sync service of its own.

What happens if I lose my computer?

Your journal goes with it, unless a copy lives somewhere else. I don't keep one on a server, so the backup is yours to make. The journal is a regular folder, so any backup you already run covers it.

Is there a mobile version?

Yes. Cozy runs on iPhone and iPad, built as its own app rather than a shrunken desktop one. It's on the App Store, free to download, with a one-time $29.99 unlock inside the app. If you already bought Cozy, your license covers it: type in the email you bought with, then the six-digit code I mail you, and the app unlocks. No second purchase. Android comes after.

Is Cozy a journal app or a diary app?

Whichever word you use. Some people keep a journal, some people keep a diary, and Cozy is built for the same habit either way: a dated entry, a calendar to look back through, and a folder of plain files that stays yours. There are longer versions for Mac and Windows.

Do I have to pay for updates?

No. Cozy Standard includes a year of updates. After that your version keeps working forever, and another year is $24, only if you want it: renew from your license page. Bought at the old price? Your renewal stays at $17. Cozy Forever includes every future version, and moving to it from Cozy Standard is $39.

I lost my license key. Can I get it back?

Yes. Recover your key, enter the email you bought with, and I'll send it back. That email also has a sign-in link where you can see every key you own and free up a computer you've stopped using.

Time to write about your day?

Pay once, and Cozy covers every Mac, Windows, iPhone and iPad you own.
