Heynote

General Information

  • Website
  • Documentation
  • Changelog

Heynote is a scratchpad and note-taking app for developers and power users. 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.

Heynote buffers are 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. Just hit Ctrl/Cmd + Enter to create a new block.

Available for Mac, Windows, and Linux.
