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.

To develop Heynote you need Node.js and you should (hopefully) just need to check out the code and then run:
> npm install
> npm run dev
To run the tests:
> npm run test
To run the tests in the Playwright UI:
> npm run test:ui
I'm happy to merge contributions that fit my vision for the app. Bug fixes are always welcome.
See the documentation.
No, at the moment this is out of scope, sorry.

Heynote is built upon CodeMirror, Vue, Electron, Math.js, Prettier and other great open-source projects.
