This is what your workspace looks like. Seriously.
Not Just Audio. A Visual Experience.
The only AI audiobook platform with Storybook Mode and Read Along.
Storybook Mode
ElenaprotagonistThe forest was silent save for the distant call of a nightingale. Elena pressed her palm against the ancient oak, feeling the bark rough beneath her fingers. The map had brought her here — to this clearing, at this hour — and she could not shake the feeling that the trees were watching.
“We shouldn't have come here,” Marcus whispered from behind the thornwall. “Not tonight. The garden doesn't forgive trespassers.”
She didn't answer. Instead, she stepped forward, through the archway of twisted branches, into the moonlit clearing where the stone fountain stood exactly as the old keeper had described it — cracked, moss-covered, and humming.
Read Along
The rain hammered against the window pane. She knew, even before opening the letter, that everything was about to change.
The envelope was thin — just a single sheet folded in thirds. No return address. Her name in handwriting she hadn't seen in seventeen years.
“Wait,” she whispered, pressing the paper flat on the table. “This can't be right. Unless... unless he knew all along.”

Turn Any Book Into a Professional Audiobook
Notevibes is an AI audiobook generator that converts your EPUB, Kindle, or PDF into a finished audiobook in one afternoon. Upload your manuscript, and AI handles the rest: chapter detection, character identification, voice assignment, and scene-by-scene narration with 550+ voices across 72 languages.
Unlike traditional audiobook production that costs thousands of dollars and takes weeks, AI narration lets indie authors, publishers, and content creators turn a book into an audiobook without hiring voice actors, booking studio time, or managing post-production. Every export is ACX-compliant and ready to publish on Audible, Apple Books, Spotify, and Google Play Books.
What makes Notevibes different is how much of the performance you actually control. Build characters once in your library — portraits, persona, archetype, outfit references — and reuse them across every book in the series; a character\u2019s voice, look, and vibe stay consistent from book one to book seven. Direct each scene with per-paragraph voice notes ("hushed, confessional \u2014 rain at the window"). Drop inline emotion tags like [whisper], [urgent], [breathless], or invent your own creative tags per character — they fire only where delivery actually shifts, not glued to every line.
And after the audio is generated, Storybook Mode turns your audiobook into a visual reading experience with genre themes, AI-generated character portraits, and scene illustrations. Read Along adds word-level highlight sync so listeners can follow along in real time. Built-in analytics show you exactly how your audience listens: plays, completion rates, and geographic insights.

Upload your manuscript. AI identifies every speaker, writes scene direction for each paragraph, and drops inline [emotion] tags at the exact spots where delivery shifts.
The rain hammered against the window. She knew, even before opening the letter, that everything was about to change.
The envelope was thin — just a single sheet folded in thirds. No return address. Her name in handwriting she hadn’t seen in seventeen years.
[whisper]“Wait,” she whispered, pressing the paper flat on the table. “[breathless]This can’t be right. Unless… unless he knew all along.”
[cold]“You weren’t supposed to find that.” His voice came from the doorway, flat and measured. “[menacing]Not yet.”

Elena Voss
Reluctant heir, sharp-tongued
Persona
Late 30s. Controlled alto. Favors precision over warmth. Cracks only in private.
Emotion Vocabulary
The Queen
Deposed monarch, theatrical
Persona
Regal, baroque cadence. Loud vowels. Every line is a performance for an audience of one.
Emotion Vocabulary
Old Keeper
Gatekeeper, weary oracle
Persona
Weathered bass. Slow. Speaks in half-riddles. Tenderness hidden under gruffness.
Emotion Vocabulary
Five things you control for each character
Everything lives on the character — not on the book. Change it in one place, hear it update everywhere the character speaks.
Portrait & Ref Sheet
AI-generated from your description, or upload your own. Portrait anchors identity; ref sheet locks proportions and outfit details for Storybook Mode and scene illustrations.
Voice + Persona
Pick from 550+ voices. Write a persona line that captures how they actually sound — "late 30s alto, controlled, cracks only in private" beats "female voice."
Emotion Tag Vocabulary
A short list of tags that belong to this character: [measured], [whisper], [venomous]. AI uses them when writing delivery, and you can always add your own creative tags.
Outfits & Weapons
Visual variants for comic/storybook modes. "Coronation robes," "road leathers," "study coat" — switch per scene, keep the face identical.
Reference Images
Upload any number of inspiration images — faces, fabrics, paintings. The AI looks at these when generating portraits and scene illustrations.
Shared Across Every Book
Your Elena in Book 1 is the same Elena in Book 7. Link detected speakers in new manuscripts to your library characters with one click.
Characters link to any audiobook, podcast, or bedtime story in your account.
