Chapters and running order
Split, merge, reorder, rename, retype. Nothing here is locked — the same structure drives the eBook, the print PDF and the audio.
Editing chapter
Narration prep
This is what separates a robot read from a narrator: nothing left on the page that a voice would trip over, and the same decision made the same way in chapter 1 and chapter 60.

What to make
Look
Author
An idea in, a finished book out — researched against the live web, written chapter by chapter, held consistent by a continuity bible, and measured against a real page count. Up to 600 pages. It runs on its own and picks up where it stopped.

Continuity bible
Fact check
Nothing checked yet. Each claim is pulled out of the text, searched for, and marked supported, unsupported or wrong — with the page it was checked against.
Self-plagiarism and repetition
Finds passages the book repeats to itself — the thing that gives a long AI-written book away.
AI Studio
Write it, edit it, name it, teach it how to say your names, translate it, and sell it. Every job runs chapter by chapter with a progress bar and a stop button, and nothing is applied to the book until you say so.

Narration intelligence
Pronunciation miner
Finds every proper noun and odd word in the book, then writes you a pronunciation list so a name is said the same way in chapter 1 and chapter 60. Review before you apply it.
Narration direction
Reads the chapter and suggests pace, warmth and emphasis, then sets the engine parameters to match.

Marketing kit
Back-cover copy, store description, subtitle options, 7 KDP keywords, 3 categories, social posts and ad copy.

Cast
A full-cast audiobook from one manuscript. The AI works out who is speaking each line, you give each character a voice, and the recorder switches voices mid-chapter without you doing a thing.
Who's in the book
The narrator reads everything that isn't dialogue.Tagged script
Find the speakers to see the tagged script.
Record the audiobook
Chunks cut at sentence ends, each one sent with the surrounding text so the voice doesn't reset between them, then joined, levelled and topped and tailed to retail spec.
Studio
The recorded chapter, laid out block by block. Click a block to hear it. If one line came out wrong, retake that line — not the chapter.

Room tone
Quality control
The checks a distributor runs, run here first. Audio measured against the retail spec, the book measured against what KDP asks for.
Audio — retail spec
Record something, then measure it. Loudness, peak, noise floor, DC offset and file length are all checked.
Book — publishing preflight
Metadata, cover size, spine against the real page count, structure, empty chapters and pronunciation coverage.
Costs before you commit
Rates are yours to set — plans change and these are only estimates. Check your own dashboard before a long book.
Deliverables
MP3 exports carry title, author, album, track number and cover art, so they land in a player looking finished.
