ChapterKeep

Keep reading and listening to the same story. ChapterKeep brings your own audiobooks into a personal library and helps you move between the recording and the matching printed book or ebook.

FROM A PAGE TO YOUR AUDIOBOOK
Open Resume from Page and scan a page live, take a photo, or choose a photo or screenshot. Select the line you want to hear, then play from the matching place in your audiobook.

FROM YOUR AUDIOBOOK BACK TO READING
Pause your audio and open Find My Place. Show ChapterKeep a page from your print book or ebook on another screen. It can guide you forward or back and show the line to start reading from when you reach the right page.

PREPARE WHEN YOU CHOOSE
Open both tools directly in Book Details. Page matching preparation is optional, and ChapterKeep remembers your preparation choice for future imports. Cancel preparation whenever you need and start it again later.

Page matching supports English audiobooks and matching English text on supported iPhone and iPad models with iOS or iPadOS 26 or later. Prepare the audiobook on your device before matching pages. Initial setup may download Apple's English speech assets.

BRING YOUR OWN AUDIOBOOKS
Import compatible DRM-free M4B, M4A, MP3, AAC, and FLAC files from Files, or import a ZIP containing audiobook tracks. You can also transfer files over USB using Finder on a Mac or Apple Devices on Windows. Audio is copied into ChapterKeep for offline listening. Use the audiobook recordings you own alongside your print books or ebooks.

LISTEN AT YOUR OWN PACE
Resume your saved position, navigate chapters when available, adjust playback speed and skip intervals, set a sleep timer, and use background playback and Lock Screen controls. Optional iCloud listening-position sync helps you continue the same imported book on another device. Import the audio separately on each device.

MAKE YOUR SHELF YOURS
Browse a 3D walnut bookshelf with text-only spines. Glide across the books for a small preview, or tap a spine to pull a book forward and rotate it. Personalize prominent covers with 17 frame choices, including wood, gold, gothic, fantasy, cyberpunk, and sci-fi styles. Set a default frame or choose one for each book. Edit book details, choose cover artwork, and explore book suggestions.

KEEP THE MOMENTS THAT MATTER
Save bookmarks and quotes, record ratings and reviews, and track the books you finish. Explore your listening statistics and keep a rating history when you remove a book from your library. Export your library as JSON or your ratings as CSV.

Online discovery, cover search, external links, and iCloud sync use an internet connection. Imported audio is available offline.
