An offline notes app that writes plain Markdown files. Edit in blocks, reach every command with the mouse or the keyboard, and turn on vim keys if you want them.
Download for macOS, Windows, or Linux from noteside.app, or grab a build directly from GitHub Releases.
Builds aren't code-signed yet, so the OS shows a one-time warning on first launch. The app isn't broken; your system just can't verify an unsigned download.
- macOS reports the app as "damaged." Drag Noteside into
/Applications, then clear the quarantine flag once:xattr -dr com.apple.quarantine /Applications/Noteside.app
- Windows shows a SmartScreen prompt. Click More info → Run anyway.
Full walkthrough: Getting started.
Everything lives at docs.noteside.app:
- Getting started. Install, open a notebook, write your first note.
- Editor. Tables, code blocks, callouts, math, and images as blocks you edit in place. The file on disk stays plain Markdown.
- Folders. Real subdirectories, collapsible sidebar groups, the move picker, drag-and-drop.
- Keybindings. Conventional chords, the vim subset, and how to remap either.
- Search. Fuzzy file finder and line-level content grep.
- Configuration.
~/.notesiderc, themes, and settings. - Performance. What keeps it fast at 50,000 notes.
