LinkBook от Latonis Technologies

LinkBook keeps every link, tab, and quick thought in one searchable place, right in your toolbar. Save the tab you're on with a single click, paste in any URL manually, or save every open tab at once — and with the global Ctrl+Shift+S shortcut, you can save the current tab from anywhere, even while the popup is closed.

Staying organized is just as easy. Tag your links into custom categories like Work, Study, or Watch later, search instantly across everything you've saved, and pin the links that matter most to the top of your list. A live badge on the toolbar icon always shows how many links you currently have. Alongside your links, you can jot down quick personal notes right in the same popup, so you never need a separate app for stray thoughts.

For when you need to manage things in bulk, LinkBook lets you open or copy every visible link at once, export your whole library to Excel or JSON for safekeeping, and import a previous backup whenever you need to restore it. If you ever want a clean slate, you can clear everything in one go, with a built-in Undo in case you change your mind. And since everything is stored locally in your browser, LinkBook never collects or transmits any personal data.
