Whole-book narration
Every chapter narrated end to end, exported as MP3 or M4B. Bought per book and priced by how long it runs, because a 20-hour novel is not the same job as a 2-hour one.
AI audiobook
Most books never get an audio edition, and the ones that do rarely get one in your language. Any book you translate here can be narrated — the whole thing, or just the summary when you only want the gist.
The narration
Narration follows the text you chose — read it in the original, or in the translation, with a voice that suits the book.
Summary narration is included in every paid plan. A whole-book narration is bought separately.

They serve different moments, and they are priced differently for the same reason.
Every chapter narrated end to end, exported as MP3 or M4B. Bought per book and priced by how long it runs, because a 20-hour novel is not the same job as a 2-hour one.
The book condensed to six, fifteen or forty-five minutes and then read aloud. Included in the plan — useful for deciding whether the full book is worth the hours.
Listening and reading share one position. Finish a chapter on headphones and the reader opens at the next paragraph, not back at the top.
No plan includes a full narration: a whole book runs for hours, so it is priced by how long it runs. Pick the book after you buy — a purchase does not expire.
Pro pays 20% less at every length. Narrating a summary is already included in your plan — only whole-book narration is bought this way.

Four natural text-to-speech voices, chosen per run. There is a voice for the original language and one for the translation, so a bilingual book can be heard either way.
MP3 or M4B, produced chapter by chapter rather than as one enormous file. M4B carries chapter marks, which is what most audiobook players expect.
It is priced by how long the finished audio runs: $2.99 up to two hours, $5.99 up to five, $9.99 up to ten, $16.99 up to twenty. Pro pays 20% less at every band. Narrating a summary is already included in a paid plan.
Yes, and it is often the better move. A summary listen runs six, fifteen or forty-five minutes depending on the depth you pick, and it is included in your plan — a cheap way to decide whether the full narration is worth buying. More on book summaries.
