Sideleaf 0.1.0
Use v0.1.1 for working update checks and the corrected Windows Redo shortcut. If you installed v0.1.0, download that patch manually.
Sideleaf’s first public release: a small Markdown editor for your words and your files.
- Write, split, and read views, with Markdown kept literal.
- Comments stored beside your document in a
.sideleaf.jsonfile. - Explicit saves, undo/redo, and protection against overwriting outside edits.
- Quiet daily release checks. A dismissible notice appears in the footer when a newer stable release is available. Help → Check for Updates checks manually. Updates open the release page; installation is your choice.
Install
Mac: Download Sideleaf-0.1.0-macos-arm64.dmg, open it, and drag Sideleaf to Applications. Apple Silicon and macOS 26.6.2 or later are required. The app and disk image are signed, notarized, and stapled.
Windows: Download Sideleaf-0.1.0-windows-x64-setup.zip, extract the whole ZIP, and run Sideleaf-Setup.exe. Keep the adjacent .installer folder with Setup. Requires Windows 11 x64 and the installed Microsoft Edge WebView2 Evergreen runtime. This build is unsigned; Windows may show an unknown-publisher or SmartScreen notice.
Early-release limits
On Windows, Redo in the editor uses Ctrl+Y; the native menu currently shows the wrong shortcut.
One document at a time, with manual saves. There is no crash recovery or automatic update installation. Images are not yet rendered in the preview. Keep backups of important writing.
