Aura Books is a free, fully offline audiobook player you open in any modern browser. Drop in an M4B or MP3, get chapters and cover art automatically, and pick up where you left off. No account. No cloud. No subscription.
Built for people
who actually finish their books.
Most audiobook apps treat you like a subscription number. Aura Books is the opposite: an offline-first player that respects your library, your privacy, and your time. No sign-up. No upload. No analytics on your listening habits. The audio you import lives in your browser’s storage — nowhere else.
Everything you need. Nothing you don’t.
Six things that should be table stakes in an audiobook player. Most aren’t.

Your library never leaves the device

The playback features you expect
Variable speed up to 3.5×, sleep timer, bookmarks, per-chapter scrubbing, silence skipping. The waveform is computed in a Web Worker so playback never stutters.
Works as an installable app
Add to Home Screen on iPhone or install from Chrome on Android, Windows, or macOS. Runs in its own window with native controls and lock-screen integration.
Designed for long sessions
Light and dark themes that pull palette colors from the current book’s cover art. Big, finger-friendly controls placed where your thumb already is.

No subscription. Ever.
Aura Books is free and stays free. We may eventually display a small ad on the public landing page, but the player itself is and always will be free.

The two features people tell us they didn’t know they needed until they had them.

Picks up where you left off — on any device.
Progress saves every ten seconds and on pause. Switch from phone to laptop and the chapter, position, speed, and sleep timer are right where you parked them.

Real chapter navigation, even in MP3s.
We read M4B chapter atoms and MP3 ID3v2 CHAP frames the way they were meant to be read. If a file has chapters, Aura Books finds them — Nero, QuickTime, or simple chapters.txt.
