Latest release
What’s New
Glasp 3.11.0 • Chat about the page you are reading, right in Safari. Open the Glasp button, go to Chat, and ask anything — answers stream in based on the page, and the conversation continues on your other devices. • New Community tab: see the passages other readers highlighted on this page, and browse them one reader at a time. Tap a passage to jump to it. • The Glasp button now appears before you sign in, and you can drag it out of the way when a site puts its own buttons in the same corner. It snaps to the nearer edge and stays where you left it. • Highlights: add and remove tags, write a page note, switch a page between public and private, copy everything at once, and use the new per-highlight menu to change colour, add a note, copy, share or delete. • Summary: pages behind a sign-in or a cookie wall can now be summarised, and a summary can be downloaded or shared. • Fixed: on tabs opened before the extension was turned on, the toolbar popup showed "Sign in" to signed-in users and its buttons did nothing.
