Turn your manuscript into a narrated audiobook with lifelike AI voices, a different voice for each character, and chapter-by-chapter M4B or MP3 files.
Anthra is an AI audiobook generator for authors. Import your book, cast a narrator and a voice for each character from 100+ ElevenLabs voices, and export a chapter-by-chapter M4B or MP3 audiobook, paying per character of text with no subscription.
Professional narration usually costs $200 to $400 per finished hour, which puts a full novel into the thousands. AI narration costs far less and takes hours instead of weeks. It isn’t right for every book or every store, and we cover where it fits below. If you don’t have a book yet, the AI book generator can help you write one, and the audio comes from the same manuscript.
Write it in Anthra, or import a manuscript you already have as DOCX, EPUB, PDF, Markdown or plain text.
Pick a narrator from 100+ ElevenLabs voices, then give each character their own voice. Anthra attributes dialogue to the right speaker.
Listen to a full sample chapter before you narrate the rest, and see the credit price before anything runs.
Narrate one chapter or the whole book, layering in ambience and intro stings if you want them.
Export chapter-by-chapter M4B or MP3 files, or publish a reading page where listeners can play it with a sleep timer.
Cast a narrator and separate voices for your characters, so a conversation sounds like a conversation rather than one person reading.
The audiobook is packaged chapter by chapter as M4B or MP3, so listeners can jump between chapters.
The audio comes from the same manuscript as your ebook and paperback. No separate script to keep in step.
A spoken-readability check scores how easy each passage is to read out loud and flags what trips the tongue before you pay to narrate it.
Narration uses the same pay-as-you-go credits as the rest of the studio. Credits never expire, so you pay for the books you actually narrate.
The narration you generate is yours, and paid credit packs include a commercial license.
Import your manuscript into Anthra or write it there, choose a narrator and any character voices, listen to a sample chapter, then narrate the book. When it’s done, export chapter-by-chapter M4B or MP3 files or share it from a reading page.
Narration costs 4 credits per 1,000 characters of text, with no subscription, and credits never expire. A 60,000-word novel runs to roughly 330,000 characters, or about 1,300 credits. See the pricing page for current credit packs. For comparison, ACX guidance puts professional human production at around $400 per finished hour, or about $2,600 for the same novel.
Not through a normal ACX upload: ACX requires audiobooks to be narrated by a human unless otherwise authorized, and Amazon runs its own Virtual Voice program for KDP authors instead. Rules vary by retailer and change often, so check each store’s current policy. You can also share or sell your audiobook directly from your own Anthra reading page.
Not for every book. A skilled human narrator still gives the strongest performance, especially for literary fiction. AI narration costs far less and takes hours rather than weeks, so it suits testing demand, reaching readers who already have your ebook, and formats where a performance matters less, such as non-fiction, study guides and children’s read-alongs.
No. Anthra doesn’t offer voice cloning. You choose from the ElevenLabs voice library.
Chapter-by-chapter M4B or MP3 files, exported from the same manuscript as your EPUB, PDF and print files.
