A real floating window, right in your browser.
AlwaysOnTopNotes turns a browser tab into an always-on-top sticky note. No app to install, no account to create — and your notes never leave your device. Here's exactly how it works.
The trick: Document Picture-in-Picture
You've seen Picture-in-Picture for video — a small player that floats over everything while you do other things. In 2023, Chromium shipped a more powerful version called Document Picture-in-Picture, which lets a website put any HTML into that floating, always-on-top window — not just a video.
That's the whole magic. When you click "Pop out", we move your note's live editor into a Document-PiP window. It's a genuine OS-level window that stays above every other app — including fullscreen video calls and screen shares — something a normal web page simply cannot do. Because we move the same editor (not a copy), every keystroke, your note color, and autosave keep working seamlessly across the hop.
Your first floating note in three steps
-
1. Open the app and write a note
Go to the app — no signup, no install, nothing to download. Press N for a new note and start typing. It autosaves to your browser as you go; nothing is ever uploaded.
-
2. Click “Pop out” to float it
Hit the pop-out button in the header. Your note lifts into a small always-on-top window using the browser’s Document Picture-in-Picture API — a real OS-level floating window, not a fake overlay.
-
3. Keep it visible while you work
The floating note stays on top of every other app — Zoom, your IDE, a fullscreen video, anything. Switch notes, resize it, drag it anywhere. Close it and your note snaps back to the tab.
Which browsers support the floating window?
The floating (always-on-top) window needs Document Picture-in-Picture, which today means a desktop Chromium browser — Chrome, Edge, Brave, or Opera, version 116 or newer.
On Safari and Firefox (and on phones), the floating window isn't available yet — but the rest of the app works perfectly: you can create, edit, search, color, pin, and export notes normally. The pop-out button simply hides itself when your browser can't float, so you never see a broken control.
And your notes? They never leave your device.
Everything you type is stored locally in your browser (IndexedDB) — not on any server. There is no server. The whole app is static files served from a CDN, and the source is MIT-licensed on GitHub so you can verify it yourself. Open DevTools → Network and save a note — you won't see a single upload.
