Drag this button to your browser's bookmarks bar:
Then, on any page you want to keep, click it. A small window opens with the link and title filled in — add tags and press Save. Text you had selected becomes the note.
Can't see the bookmarks bar?
Press Ctrl+Shift+B (⌘+Shift+B on a Mac) to show it.
If nothing happens
A few sites block bookmarklets. Use + save at the top of this site instead and paste the link.
On a phone?
Bookmarklets barely work on phones. Save from the share sheet instead.
