Vertical Tab Memo is a tiny web app that turns your browser’s vertical tabs into one-line notes. Instead of opening a separate app, you can simply use tabs themselves as a lightweight memo. Each tab becomes a piece of text, so your tab bar turns into a live, visual note list. No login, no setup — just open and start typing. It’s simple, a bit weird, and surprisingly fun.
