Heynote
General Information
- Website: heynote.com
- Documentation: heynote.com
Heynote is a dedicated scratchpad for developers. It functions as a large persistent text buffer where you can write down anything you like. Works great for that Slack message you don't want to accidentally send, a JSON response from an API you're working with, notes from a meeting, your daily to-do list, etc.
The Heynote buffer is divided into blocks, and each block can have its own Language set (e.g. JavaScript, JSON, Markdown, etc.). This gives you syntax highlighting and lets you auto-format that JSON response.
Available for Mac, Windows, and Linux.

FAQ
Where is the buffer data stored?
See the documentation.
Can you make a mobile app?
No, at the moment this is out of scope, sorry.
Can you add a feature for naming blocks and/or adding tags? (#44)
Currently, I'm not planning on adding this. The main reason is that it goes against the scratchpadness of the program.
I can totally see the usefulness of such a feature, and it's definitely something that I would expect from a more traditional Notes app. However a large part of Heynote's appeal is it's simplicity, and if that is to remain so, I'm going to have to say no to a lot of actually useful features.
What are the default keyboard shortcuts?
See the documentation.
Thanks!
Heynote is built upon CodeMirror, Vue, Electron, Math.js, Prettier and other great open-source projects.
