About Codex Books

Codex helps you build and organize a personal book library from the books around you. Scan a book cover with your camera, pick a photo from your library, scan an ISBN barcode, or search by title, author, or ISBN. Codex retrieves book details such as title, author, year, cover, description, and ISBN, then saves them into your library for quick browsing and lookup. Your collection can be sorted by author, year, or category, and books can be grouped into genres and adjusted manually when needed. You can also export your full library as JSON for backup or sharing. Features: - Scan book covers with OCR-based search - Scan ISBN barcodes with the camera - Search manually by title, author, or ISBN - Save title, author, year, category, description, cover, and ISBN - Organize books by author, year, and category - Edit categories and remove books from the library - Export your collection as JSON - Sync your library through iCloud - Codex is designed for readers who want a fast way to catalog physical books without maintaining a spreadsheet by hand.Note:In order to function, the app needs Google API with Books API access which can be configured via the app settings.
