A private journal that stays yours

Cozy is a local-first journaling app for Mac and Windows: your entries live on your own computer as plain text files. Nothing synced to a server, nothing fed to an AI — yours to keep or share as you please.

For macOS & Windows · One-time purchase, no subscription · 14-day money-back guarantee

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.

What can you find in Cozy?

I wanted a journal that stays yours and feels good to open. So Cozy keeps your writing in plain files on your computer, with small touches that make you want to come back.

Your files, on your computer

Nothing is stored on a server. Your thoughts, experiences and writing are yours forever. So don't worry about it.

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 café. 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.

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.

Your thoughts stay in your head. Your entries stay on your device.

I built Cozy because I wanted a private place to write, not another app quietly collecting what I put into it. Everything you write stays on your own device. That's the whole point.

Nothing synced to a server

There's no mystery cloud. Your journal lives right where you write it, on your own computer. No breach to worry about, no subscription to pay, no stranger who can open your diary.

Nothing fed to an AI

I don't think your private writing should be used to train anything. Nothing you write in Cozy is scraped, read, or sent off to an algorithm. No AI, simple as that.

Your words are yours

What you write belongs to you. Maybe you're working through a rough day, maybe you're just keeping track of life as it happens. Either way, you stay in charge: keep your entries to yourself, or export and share them whenever you like.

What early users are saying

Cozy is still in its baby stage, but here are some of the things my wonderful early users have said about it ✨

After using Day One for 15 years, I've made the jump to another journaling app. I never thought this day would come to be honest, I was locked in to Day One and even put my old handwritten entries in there. 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 on and already offers some features I've been wanting in Day One, such as image resizing. I had some issues with the import feature and the developer was very responsive, even releasing a fix that same day. I hope everyone who is frustrated with Day One finds an alternative that suits them.

I was a Day One user, but woke up one morning to them encouraging me to use AI to “interrogate” 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!

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.

Hey Alberto, I just wanted to say you're really awesome for making an app like this. It has so much potential, and even in its current state it is a joy to journal with.

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!

Frequently Asked Questions

How much does Cozy cost?

Cozy is a one-time $35 purchase, no subscription. One license covers every Mac and Windows you own.

Do you offer student or country discounts?

Yes. I want Cozy to be affordable wherever you are. If you're a student, or if the price is steep for your country, email me and I'll send a discount code. Mention where you study or which country you're in so I can send the right one.

Do I have to pay for updates?

No. You're buying Cozy 1.0, and every update to it is free — fixes and new features alike. Further down the line I'll release a bigger version (Cozy 2.0, then 3.0), and those are an optional upgrade at around half the price of a new license. If you're happy with what you have, you never have to upgrade, and your Cozy keeps working.

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.

Where do my entries go?

Into a regular folder on your computer, as simple files you can open with any app. Each entry saves the date, mood, location, and tags alongside your writing. Photos sit right next to your entries in the same folder.

Is there a mobile version?

A mobile version for iPhone and Android is in the works as its own app. It'll be sold on the App Store and Google Play as a separate $19 purchase — bought through the store, not unlocked by your desktop license. Writing on a desktop and writing on a phone are different experiences, and each deserves its own design. The apps read the same journal folder, so they stay in sync through iCloud, Dropbox, or whatever sync service you already use.

Can I sync between devices?

Cozy doesn't handle sync, but your journal is just a folder. Sync it with iCloud Drive, Dropbox, or any similar service and you're done.

Does it use AI?

No, and I don't plan to add it. 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.

Time to write about your day?

Buy Cozy once, and it covers every Mac and Windows you own. Simple as that.

On your phone? Buy now and install on your computer later — one license covers every Mac and Windows you own.
