Note apps that install from the browser

Short answer

Notesnook and AppFlowy both aim at the Notion shape with end-to-end encryption, and both keep working with no connection once installed. Anytype and AFFiNE go further into local-first storage, where your notes live on your device by default rather than on someone's server. CryptPad handles collaborative documents the server itself cannot read. All install from the browser with nothing to download.

Encrypted, and still usable

Notesnook encrypts end to end and still manages to feel quick, which is the hard part — most encrypted note apps pay for their privacy in latency. It works offline once installed.

AppFlowy is the open-source take on the Notion shape: databases, boards and documents in one place, and it also survives a lost connection.

Local-first, not cloud-first

Anytype and AFFiNE both start from the assumption that your notes live on your device and sync is an addition, rather than the other way round. Both keep working with the network cut.

The practical difference shows up the day a service shuts down or a subscription lapses: local-first means the notes are still there and still readable.

Writing together

CryptPad does collaborative documents where the server stores only ciphertext — it cannot read what you write, by construction. That is a genuinely different guarantee from a privacy policy promising not to.

It wants a connection, since collaboration is the point.

Why installed notes beat a bookmarked tab

A note app you open thirty times a day should not be competing with forty other tabs for your attention or your memory. Its own window and its own icon change the ergonomics more than the feature list does.

And with a filled cache, the note is there in a tunnel — which is where a lot of notes get written. The install sequence is here.

Frequently asked

Where are the notes stored?

It depends on the app, and it is worth knowing before you commit. Anytype and AFFiNE are local-first by design; Notesnook and AppFlowy sync encrypted copies; CryptPad keeps ciphertext on a server it cannot decrypt.

Can I use them offline?

Notesnook, AppFlowy, Anytype and AFFiNE all keep working with the network cut once installed and opened once. CryptPad needs the connection, since it is built for collaboration.
