offlinenotepad is an open-source offline note taking app. It is a browser-based offline-first notepad that securely syncs across your devices - including smartphones, laptops, and chromebooks. Ideally, its a minimalist note-writing experience that can be accessed anywhere, anytime.

Offline-first. All information is stored as encrypted data in the browser. Saving, editing, viewing, and searching are all done on the client.

Secure. offlinenotepad uses AES with the PBE algorithm (PBKDF2) with the crypto-js library to encrypt data on the client and the server.

Minimal. This offline notepad aims to do as much as possible with as little as possible.

Publish. Any page can be "published" so that is accessible by anyone with a simple random link, like The raw data can easily be easily cURLed by adding /raw to the end, e.g.

Code. If the title of any document contains a period (".") then it will force the editor to be monospace and it will show the plain text in the viewer instead of transformed Markdown to HTML.

This writing tool is largely based of its predecessors: cowyo and (both also available on Github).


To run your own server for backing up notes you can simply install with Go.

$ git clone
$ cd offlinenotepad
$ go generate -v -x
$ go build -v

And then you can run

$ ./offlinenotepad

Log into localhost:8251 to see the site.


Alternatively you can run with docker:

$ docker run -v /location/to/save/data:/data -p 8251:8251 schollz/offlinenotepad


I took a lot of help from @GoogleChromeLabs with their airhorn.
