Your personal library, always at hand.
Building and maintaining a personal library has always required patience. Codex Books removes the friction. Whether you are cataloguing a shelf of old paperbacks or tracking what you lend to friends, the app handles the lookup, deduplication, and storage so you don't have to.
All your data lives in your own iCloud account. Nothing is sent to us. No account required beyond your existing Apple ID.
Point the camera at any barcode and the book is found and added in seconds.
Photograph a cover and OCR extracts the title and author automatically.
Search by title, author, or ISBN to find and add any book in the Google Books catalogue.
Your library syncs automatically across all your Apple devices — no extra setup needed.
Non-English titles and descriptions are translated on request, keeping your library readable.
Export your full library as JSON whenever you want a local backup or wish to migrate.
Codex Books does not collect, store, or transmit any personal data. Your library is yours — stored in your iCloud account and never visible to us. The only external calls the app makes are to look up book metadata by ISBN, and optionally to translate text.
