Notesnook is a free (as in speech) & open source note taking app focused on user privacy & ease of use. To ensure zero knowledge principles, Notesnook encrypts everything on your device using XChaCha20-Poly1305 & Argon2.
Notesnook is our proof that privacy does not (always) have to come at the cost of convenience. Our goal is to provide users peace of mind & 100% confidence that their notes are safe and secure. Our decision to go fully open source is one of the most crucial steps towards that.
Notesnook is a user focused note taking tool meant to offer a fully end-to-end encrypted note taking experience for everyone. This includes the majority of our less tech savy users who just want to take notes without all the hassle.
In short, Notesnook aims to offer a complete replacement for other insecure note taking tools like Evernote & Notion. Because let's be honest, these tools offer great productivity but at a great cost to your privacy.
I installed this app on an android device over two years ago. I've added it to windows machines. This is the first time I've tried it on Linux. The developers have updated this app consistently and it does seem to retain platform parity. Every update so far has been an improvement in my opinion. The formatting and organization options are plentiful and easy to use. The encryption mechanisms seem solid (but I'm not an expert). They've had syncing issues and addressed them in the V3 update--so far so good. I'm 100% satisfied... and now I'm annoyed when I must use MS Word or other poorly supported doc development software. Thank you, Streetwriters team.
Easily one of the best, if not the best, notetaking app I have ever used. Works and syncs on all platforms, is open source, encrypted, and easy to use. Use it, there's no better one. I have tested most competitors (except iOS/macOS-exclusive ones) and was never happier with such an app.
