What it does
azLibrary is a desktop audiobook library manager that keeps large collections understandable: it groups books by author, universe and series, shows the metadata you need, and helps you keep the library clean.
When it helps most
It is especially useful when you keep audiobooks on an external drive, want to manage metadata without relying on cloud sync or a subscription service, or need an offline audiobook organizer for Windows and macOS.
Built for audiobook enthusiasts who want more control over their collections.
Why azLibrary?
Automatic Library Organization
Automatically organize audiobooks into a structured library based on authors, universes, series, titles, and other metadata.
Universes and Series
Go beyond simple series management by organizing books into larger fictional universes first, then series within them.
Advanced Metadata Editing
Review and update metadata, edit covers, manage narrators, universe information, series, and keep your collection clean and searchable. Color tags help with quick visual categorization.
External Drive Support
Store your collection on internal drives, USB drives, external SSDs, or network storage.
Flexible Library Modes
Keep files exactly where they are or let azLibrary manage and organize the folder structure for you.
Local-first by design
Your collection stays on your computer or drive. No account is required and the app is designed for offline use.
Two ways to manage your library
Catalog Mode
Keep files exactly where they are.
azLibrary stores metadata in its own database without moving or renaming files.
Managed Mode
Automatically organize your collection into a structured folder hierarchy.

Privacy and data handling
Local data
Library files and metadata are stored locally. The app is intended to work without an internet connection.
Multiple languages
azLibrary is localized in 7 languages, with more translations planned in the future.
No telemetry
No analytics, no ads, and no hidden data collection.
External drive support
Works with internal disks, external SSDs, USB drives, and other mounted storage when the OS grants access. Slower drives can affect book imports and metadata editing.
