📖 Format recommendation

EPUB recommended. PDF and TXT work too, but results vary.

We check your PDF before you pay. If its text can't be read properly we refuse it and tell you why, rather than sell you an audiobook full of scrambled words.

Upload Your Book

Upload an EPUB, PDF, or TXT file. We will extract the chapters, show you pricing for 3 quality tiers, and let you pick a voice before generating.

How it works

  1. 1. Upload your book — we extract chapters and estimate pricing for 3 tiers
  2. 2. Choose a quality tier: affordable, best quality, or voice clone
  3. 3. Pick a voice and pay with sats — generation starts immediately
  4. 4. Track progress in real time — download an M4B audiobook with chapter markers when done
