Bookmark keeps your place wherever you are reading—paperback, ebook, or audiobook—and brings every format together in one beautiful library. SAVE THE EXACT SPOT Photograph a paperback page, choose a screenshot from an audiobook or ebook, or save your position inside Bookmark’s built-in reader. Your latest spot stays easy to find, with a history of earlier bookmarks whenever you need it. START WITH A LIVED-IN LIBRARY Download Bookmark and begin with four included reads: • The first three chapters of The Last Bites by Chris Weiss • The Odyssey, with familiar Greek names • Dracula by Bram Stoker • The Secret of the Old Clock Each included title comes with Author’s Commentary, so you can experience Bookmark’s signature features immediately. UNLOCK AUTHOR’S COMMENTARY AS YOU READ Author notes, behind-the-scenes details, and discussion prompts appear when you reach the right place in the book. Upcoming commentary stays hidden, preserving every surprise. READ TOGETHER WITHOUT SPOILERS Create a reading group for two people or many, invite readers with a code, and decide whether to share your progress. Choose exactly which notes your group can see. Shared notes and reactions reveal to each reader only after they reach the matching spot. KEEP NOTES WHERE THEY BELONG Add text, voice, or short video notes at a reading position. Bookmark keeps your commentary, personal notes, and reached group reactions together in reading order. MAKE THE NEXT MEETING BETTER Create a spoiler-safe discussion guide from the Author’s Commentary, notes, and reactions you have already reached. Export it to share, save, or print. READ YOUR OWN FILES Open EPUB and PDF books in Bookmark’s built-in reader. Your files remain yours, and you can remove a downloaded file without removing the book or your saved position. PRIVATE BY DESIGN There is no Bookmark account, advertising, or analytics. Your personal library stays on your device and can sync through your private iCloud. Read Together sends only the information you choose to share through Apple CloudKit for that reading group. Your books. Your people. Your place.
