The Mac has no shortage of journals. Most of them you rent, and most of them keep your writing on someone else's machine.
Day One is the one everyone recommends: $49.99 a year, entries on its servers. Apple Journal is free and lives inside your Apple ID. I wanted my writing in a folder I could open in Finder, so I built Cozy.
Diary or journal, written at your desk
Some people call it a journal, some people call it a diary. It's the same thing here: you sit down in the evening and write what happened. Cozy works either way, a dated entry, a calendar to move through the months, and a folder of files you own at the end of it. If you've been searching for a diary app for Mac and getting phone apps or subscriptions, this is the desk version.
It behaves like the rest of your Mac
It follows the system light and dark mode, so it looks right at 8am and at midnight, and macOS Text Replacements work in the editor the way they do everywhere else on your Mac.
Your journal is a folder of files on your Mac
Underneath, your journal is a folder of plain files you can read in any editor, now or in ten years. There's no account to sign up for, no password to forget, and no server holding your entries, which is why it works offline. Because it's a folder, you can drop it in iCloud yourself and open the same journal on another Mac or a PC.
macOS already knows how to look after a folder
Because every entry is its own file, named by the date you wrote it, the tools already on your Mac work on your journal without any help from me. Finder sorts it by date and finds an entry by name. Press space and Quick Look reads one without opening Cozy. Spotlight searches inside the entries, not just the names. Time Machine backs the folder up the way it backs up everything else, versions included. Moving your journal to another Mac is moving a folder. Nothing here needs an export step, and nothing here stops working the day Cozy does.
Quick entry from the menu bar
Most thoughts worth writing down show up while you're doing something else, so Cozy also sits in the menu bar behind ⌘⇧C: you write the line, hit save, and get back to what you were doing.
Drag an iPhone photo onto an entry and it goes in, HEIC and all, no converting first. iPhone video works the same way, and so do audio files and voice memos.
One purchase, all your machines
It's $49, paid once. That license covers every Mac you own, your Windows PCs, your iPhone and your iPad, so there's no per-device math and nothing renewing quietly every year. Cozy Forever is $89 once and includes every future version for life.
How does Cozy compare to other Mac journal apps?
I built one of these, so take my opinion for what it is. But the facts in this table are the ones I'd want if I were choosing, and where another app is better than Cozy, it says so.
| App | Price model | Where entries live |
|---|---|---|
| Cozy | $49 once, every device | Plain text files you keep |
| Day One | $49.99–$74.99 a year | Day One's servers, encrypted |
| Apple Journal | Free | Apple's Journal system |
| Obsidian | Free, Sync $48 a year | Plain text files you keep |
| Bear | $29.99 a year | Bear's own database |
| Diarium | About $9.99 per platform | Diarium's own database |
| Journey | $49.99 a year, or $199 once | Journey's cloud, own format |
Two things the table can't hold. On sync, Day One, Bear and Apple Journal handle it for you, Journey and Diarium sync through their own cloud or a drive you connect, and Cozy and Obsidian ask you to put the folder in iCloud once. On offline, all seven let you write with no connection, but only the two that keep your entries as files work fully offline, because the rest have to reach a server to sync.
Day One on the Mac
The most polished journal on the Mac. It syncs everything for you across Mac, iPhone, iPad, and Apple Watch, handles photos and video well, and its end-to-end encryption is good. But it's $49.99 a year for Silver or $74.99 for Gold, and your entries sit on Day One's servers in a format only Day One reads, so leaving means exporting. If you want mobile today and don't mind renting, it beats Cozy. Cozy vs Day One →
Apple Journal
Free, quiet, and Apple's privacy claims here aren't marketing, entries are encrypted on device and in iCloud. It started on the iPhone and the Mac version came later, still carrying the phone's shape. Your journal lives inside the Journal system and your Apple ID, so it isn't there the day you sit down at a Windows machine, and getting your writing out as files means an export. Cozy vs Apple Journal →
Obsidian
Free, and it shares Cozy's most important idea: your writing is plain text files in a folder on your own Mac. Lots of people journal in it. The difference is how much it asks of you. You pick the folders, tags, templates, and plugins, and there's no calendar, mood, or moments timeline unless you build them. Sync is $4 a month billed annually, or you point it at iCloud like Cozy does. Cozy vs Obsidian →
Where Cozy falls short on the Mac
Two things: there's no Android app. Cozy runs on Mac, Windows, iPhone and iPad, so if your journaling lives on an Android phone, Day One and Journey serve you better today. And there's no sync service. You drag the folder into iCloud or Dropbox and it syncs like your other files, which takes a minute and then works, but it is a minute Day One doesn't ask of you.
Head-to-head: Cozy vs Day One, Cozy vs Apple Journal, Cozy vs Obsidian, Cozy vs Bear, Cozy vs Diarium, Cozy vs Journey.

“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!”
