AI audiobook generator for fiction authors
Paste the manuscript you already have and turn it into a directed, multi-voice audiobook — cast, performed, and mastered — in hours rather than months.
Most generators read a whole book in one flat voice. Fiction needs more than that: a narrator, a cast of distinct characters, and the room to shape how a line lands. Book Director Studio is built around that idea. An AI director reads your chapter, separates narration from dialogue, finds who is speaking, and drafts a performance note for every line before a single second of audio is generated.
You stay in the chair. Cast each character from the voice library, rewrite a performance note, preview a change for free, and re-render only the lines you touched. When the chapter sounds right, export an audiobook-ready file you own.
It reads like a director
The AI parses your chapter into narration and dialogue, detects characters, writes a scene context, and adds a per-line performance note — not just a wall of text-to-speech.
30 AI voices, cast per character
Assign a distinct voice to your narrator and to each character. Audition every voice in your own words first; the studio warns you if two characters share one voice.
Direct line by line
Open any line to set a performance note, adjust pacing, or tune speed and pitch. Preview a line free, then re-render just that line — you are charged only for the audio you regenerate.
Conversations that overlap
Link consecutive lines so a back-and-forth exchange renders as one conversational pass — the rhythm of two people actually talking, up to two speakers per passage.
Mastered to spec
The ACX-style export preset masters loudness, trims dead air, and pads room tone, then runs a readiness report against the ACX technical spec so you can submit with confidence.
You own the files
Export a chaptered M4B or a universal MP3 and download it. No store lock, no exclusivity — distribute wherever AI-narrated audio is accepted.
Paste or upload your manuscript
Drop in a chapter, or upload a whole book as .txt, .md, .docx, .pdf, or .epub and let the studio detect chapters from your headings.
Parse and cast
The director splits narration from dialogue, identifies your characters, and suggests a voice for each. Adjust any casting before you render.
Direct the performance
Tune the lines that matter — a whispered confession, an urgent warning — and hear free previews until the read is right.
Render and export
Render the chapter, mark it ready, and export an audiobook-ready M4B or MP3 with chapter markers and a retail sample.

Five finished hours a month — about one novel a quarter, with credits left over for retakes. Start free with an hour of audio on the house.
- Does it work with a full novel?
- Yes. Upload the manuscript and the importer detects chapters from your headings, so you can build the book chapter by chapter. Credits are measured in finished minutes of audio (about one minute per 140 words), reserved when a render starts and settled to the actual length when it finishes.
- Can I keep editing after the first render?
- Always. Edit a line, change a voice, or move a pause, and only the affected lines are marked for a fresh take. Re-rendering a single line or linked passage charges only for the audio regenerated, and previews are free.
- Are the voices AI generated?
- Yes. The catalog is built on Gemini-native AI voices, so all generated audio carries Google’s SynthID watermark. You audition each voice before casting it.
- What can I do with the finished audiobook?
- Export a chaptered M4B or an MP3, download it, and distribute it on any platform that accepts AI-narrated audio. Each retailer sets its own acceptance rules, so check the platform before you submit.
Your audiobook starts at the next blank line.
