About
I used paper sticky notes to keep little reminders beside my work. But I wanted those notes with me wherever I went—at another desk, while travelling, or anywhere I opened my laptop. Notes on a wall could not come along.
So I asked myself: why not make sticky notes that stay at the edge of my Mac? That is how Sideleaf was born.
Hover to peek at a note, click to write, then move away and it tucks back into the screen edge. It keeps quick notes, checklists and reminders beside what I am doing. I also wanted to rely less on disposable paper sticky notes.
Sideleaf is a native Mac app for macOS 26 or later. Your notes stay on your Mac, with no account required. Try every feature free for 7 days, then unlock editing with a one-time purchase. No subscription. Existing notes remain readable, searchable and exportable after the trial.
Would keeping notes at the edge of your laptop fit the way you work? I would love feedback on the interaction.
