AIWriteBook has every feature your book needs

Writing, editing, formatting, covers, publishing and audiobooks.

1. Book editor that reads your whole manuscript before it edits

The Book Editor reads every chapter before it suggests a single line. It scores the book on 30 criteria for its genre and writes an editorial letter, then runs line edits that also proofread. You accept or reject each change, and what you accept goes straight into your book. Half a draft in a drawer? Finish the book you started.

Chapter 3 · The Letter
1 of 4 reviewed

Mara walked slowly into the kitchen and she saw that the letter was still sitting there on the table. She had been avoiding it for three days now.. The letter was still on the table, where it had sat for three days. She picked it up and she turned it over and over in her hands.

  1. 1Filler cut

    The pause already carries the hesitation.

    Accepted
  2. 2Run-on split

    Two beats, two sentences.

  3. 3Repetition

    Third "she" in two lines.

  4. 4Filler cut

    Once is enough to show the nerves.

2. Book formatter that makes print and ebook files for every store

Formatting is a step inside every book. It builds a print-ready PDF interior and a wrap cover with the spine and barcode worked out from your page count, for Amazon KDP, IngramSpark, Lulu, Draft2Digital with Barnes & Noble Press, and BookVault. The same run gives you an EPUB for ebook stores, a DOCX and an ebook cover, so the ebook and the paperback come from one file. You choose the trim size, the interior style, the paper and the front and back matter. Margins, gutter, bleed and the table of contents are worked out for you, and a preflight check lists anything a store would reject.

3. KDP Chrome extension that fills in Amazon for you, plus keyword and category research

The KDP Chrome extension opens a panel beside Amazon's title setup form, checks each field against Amazon's rules while you type, and fills the Details, Content and Pricing pages from your book. You review every page and press Publish yourself. Its category and keyword research reads live Amazon data and returns three categories and seven keywords, and the same research runs in the KDP keyword research and category finder tools.

4. Cover generator that draws covers for your genre

Make a cover on the book's Metadata step or with the standalone cover generator, in 21 art styles, with the title and author name drawn into the artwork. Put it on a 3D mockup for launch posts, then plan the rest of your book marketing. Every cover below came out of the generator.

5. Picture book maker that keeps characters the same on every page

Visual books are their own book type, for picture books, coloring books, comics and manga. You set the art style once and build a reference sheet for each character, so the otter on the first page is the same otter on the last. Then you lay out the pages, edit text and images on a canvas, and export print files with bleed. It also makes bedtime stories and alphabet books.

6. Audiobook studio with a narrator and a voice for each character

The Audiobook Studio reads a chapter, works out who speaks each line and proposes a voice for every character next to your narrator. You check the cast before anything is recorded, re-record any single paragraph, and export mastered MP3 files or an M4B with chapter markers, from 25 voices.

Quality Over Quantity

We made AIWriteBook to finish and publish our own books, in our own voice, without juggling five tools. Now you can do the same.

We ran into the same problems you do

We write and publish books too. Before AIWriteBook, one book meant an outline in one app, drafts in a chatbot, edits in a grammar checker, and separate tools for the cover, the formatting and the KDP listing. The drafts rarely sounded like us.

So we built one place that takes a book from an idea or an unfinished draft to a published file. Upload your earlier writing and the AI drafts in your pacing, your dialogue and your chapter rhythm.

You stay in charge the whole way. Edit the outline, rewrite any chapter, and export a KDP-ready manuscript once it reads the way you want.

We publish with it ourselves

Real books in front of real readers

Every book on our sister site, NanoReads.com, was written with AIWriteBook: 90+ of our own titles, plus 560+ that AIWriteBook authors cross-published there. More than 140,000 readers have opened one.
