Encrypted Microsoft OneNote Alternative

Using OneNote? Try Notesnook and go 100% private

Get started for free

End to end encryption

Notesnook is by default private. Enjoy rich and powerful note taking while keeping your notes 100% end-to-end encrypted. If you use OneNote online, you have to trust Microsoft that they won't misuse your data. With Notesnook it's impossible for us or any third party to read your notes.

Never risk your privacy again

No matter how many times Microsoft tells you that they respect your privacy and won't read or access your notes. As long as your notes are not encryped, they are always at risk. So any employee at Microsoft OneNote or the government can get access to them anytime they want. Because they can.

A key to a door that can be broken

Imagine a Microsoft server get's hacked. All your notes & data can be easily accessed and used for what not. Even with the best security, there's still a possibilty of a data breach. Therefore Notesnook encrypts your data. No one except you can read your notes. It's just impossible.

Unlike OneNote web, you can encrypt notes before sharing.

Built-in privacy lock

Unlike OneNote with Notesnook, you get a dedicated privacy lock that let's you stop intruders from getting into your notes even when your phone is not locked.

Great note editing

We believe that everyone uses a notes app differently. Some people need some features and other's don't. Notesnook simplifies everything in the editor for you so you can write notes without wasting time.

A note editor that conforms to your needs

Only OneNote web for Linux users

There's no OneNote desktop client on Linux. So to have a better note taking experience you have to install Windows or Mac? Notesnook is a OneNote linux alternative with clients for desktop & web.

OneNote Notebooks

Like OneNote, Notesnook has Notebooks & topics which you can quickly get used to. But that's not it. Notesnook allows colors, favorites, pins and tags so you have more options to organize your notes.

What's an online notepad without syncing?

Not an online notepad, duh! Notesnook syncs to all your devices and it doesn't compromise your privacy on the way.

Notesnook is going open source

Notesnook is going to be fully open source soon unlike OneNote. We don’t want you to just trust us or our privacy policy. You can see everything for yourself and report suggestions, improvements and even contribute. Visit our Github.

We believe in community and the voice of our users

Notesnook app is what Evernote should have become long ago. And they're still improving.
I work in content writing and communications. My day starts and ends in Notesnook. My Chrome app is always open; it's where I take all my notes. The clean design, Focus mode, the tagging and color coding are all features that help keep my work organised every day.
This app is really great so far! (using the android version currently) looking forward to maximizing the **** out of this. Also i think you should mention off the bat that unlimited storage in the pro version means file upload (pics, etc).
