SideNotes is a native Mac note-taking app built for moments when opening another window would break your flow. It slides in from the edge of the screen, stays above other apps when needed, and disappears just as quickly.

Notes without app switching
Capture ideas, tasks, links, screenshots, snippets, and file shortcuts from anywhere on your Mac. Organize notes in folders, add colors, pin important items, search across your library, and fold longer notes to keep the interface compact.

• Hidden Markdown keeps formatted notes clean while you write.
• iCloud sync connects your Macs and, with SideNotes Mobile sold separately, your iPhone and iPad.
• Automatic backups add another layer of safety.
• Apple Shortcuts, AppleScript, and a URL API connect SideNotes to wider workflows.
• Themes and detailed appearance settings let the app fit your desktop.

SideNotes is made for students, developers, designers, writers, and anyone who wants a dependable place for information that should remain close at hand. It is private by design and does not collect notes, personal data, analytics, or telemetry.
