Alice's Adventures in Wonderland

Alice asks the grinning Cheshire Cat for directions — and gets none.

NarratorNaomiStoryteller

The Cat only grinned when it saw Alice. It looked good-natured, she thought; still it had very long claws and a great many teeth, so she felt it ought to be treated with respect.

AliceAbbyCurious

Cheshire Puss, would you tell me, please, which way I ought to go from here?

Cheshire CatSnikSly

That depends a good deal on where you want to get to.

AliceAbbyCurious

I don't much care where—

Cheshire CatSnikSly

Then it doesn't matter which way you go.

AliceAbbyCurious

—so long as I get somewhere.

Cheshire CatSnikSly

Oh, you're sure to do that, if you only walk long enough.

How it works

Audiobook maker: from file to finished book in four steps

  1. Upload the book

    Drop in your manuscript or ebook as EPUB, PDF, DOCX or TXT, or paste the text. Files must be DRM-free, and scanned PDFs need a text layer to be read.

  2. Find the chapters

    Chapters are read from the table of contents or the headings, and every speaking character is detected, so each line knows who is talking.

  3. Cast and direct

    Give the narrator and each character a distinct voice, then direct the delivery with notes in brackets like [whisper] and sound tags like [laugh] or [sigh].

  4. Export the audiobook

    Download an M4B with chapter markers, one MP3 for the whole book, or a ZIP with a file per chapter. Keep the same cast for the next book in the series.

Formats

Ebook to audiobook: what goes in, what comes out

Bring the file you already have, or paste the text. The only limits are DRM-protected store downloads and scanned PDFs without a text layer.

Features

An AI audiobook creator built for books, not clips

  • A voice per character

    Every speaking character is detected and given a distinct voice, plus a narrator. Keep the same cast across every book in a series.

  • Common ebook formats

    EPUB, PDF, DOCX, TXT and Markdown, or paste the text straight in. Store downloads must be DRM-free, and scanned PDFs need a text layer to be read.

  • Chapters that hold their shape

    Chapters are read from the table of contents or the headings, so every scene stays inside its chapter. A file with no contents page is split on its chapter headings.

  • M4B with real chapter markers

    Each chapter becomes a marker in the M4B, with its title, so listeners can jump straight to any chapter in their audiobook app, even hours into the book.

  • Pick every voice yourself

    Keep the automatic casting or swap any character to another voice. Give the narrator and leads premium voices, and the minor roles standard ones.

  • Direct every line

    Write the delivery you want in brackets, like [whisper, like sharing a secret], and add sound tags such as [laugh], [sigh] or [breathe] right in the text.

Genres

AI audiobooks for every genre

A thriller needs a different cast than a bedtime story. Pick a genre to see a sample AI audiobook line-up, then recast any role in the studio.

Fantasy

A steady narrator for the long road, a raider who sounds like one, and a sorceress you won't forget.

Who it's for

An AI audiobook generator for authors and readers

  • Self-published authors

    Turn the DOCX or EPUB you already sell into an audio edition, chapter by chapter, at your own pace.

  • Fiction with a cast

    Web novels, LitRPG and fanfic: give the hero, the villain and the narrator their own voices, and keep them the same all series long.

  • Podcasts and stories

    Turn a script, a serial or a bedtime story into an episode, with a narrator and a distinct voice for each character.

  • Readers and listeners

    Have a DRM-free EPUB or a public-domain classic you'd rather listen to? Bring it in and let the chapters split themselves.

Compare

AI audiobooks with a full cast vs the usual ways

There are three usual ways to turn a book into audio. Here is how full-cast AI audiobooks from FullCastBook compare with one text-to-speech voice and with hiring narrators, including where a human narrator still wins.

FullCastBookSingle-voice text-to-speechHiring narrators
A distinct voice for every characterYes: AutomaticNo: One voice for everyoneYes: With a full-cast budget; usually one narrator voices everyone
Direct how any line is deliveredYes: Notes like [whisper] right in the linePartly: Limited, or not at allYes: In a studio session

FAQ

AI audiobook generator FAQ

Is this a free AI audiobook generator?

You can start free. The demo on this page plays a full-cast chapter without an account, and a free account (no card) comes with credits to voice a chapter of your own. A whole novel needs a paid plan.

Which ebook formats can I turn into an audiobook?

EPUB, PDF, DOCX and TXT, or paste the text straight in. Files have to be DRM-free, so a locked store download won't open; use a copy you exported yourself. Save older .doc files as DOCX first.

Does it work with scanned PDFs?

No. There is no OCR step, so a PDF made from page images has no text to read. A PDF exported from a word processor has a text layer and uploads fine.

What do I get when I export?

An M4B audiobook with chapter markers, one merged MP3 for the whole book, or a ZIP with one file per chapter. The files are yours. Each store sets its own rules for AI narration, and Audible/ACX doesn't currently accept it, so check before you publish.

How are credits counted for a book?

Generation uses credits, counted by the characters of text that get voiced, so a longer book needs more. The free credits you get on sign-up let you hear the cast on a sample first; a full novel needs a paid plan.

See plans and credits on the Pricing page.

What is the best AI audiobook generator for books with many characters?

Look for one that casts the dialogue, not just the narration. This one detects every speaking character, gives each a distinct voice next to the narrator and keeps the cast for the whole series. English works best today, so try a sample chapter in other languages first.
