Aivolut Books vs AIWriteBook: one drafts, one runs the whole launch

You’ve got years of know-how in your head, or a half-finished manuscript in a folder, and the book still isn’t getting written. Both of these AppSumo lifetime deals promise to close that gap. They go about it in quite different ways, and the difference matters more than the price tags.

A quick note first. We haven’t used either tool. Everything here comes from the listings, AppSumo’s buyer summaries and, for AIWriteBook, a short founder video. That’s vendor material, so read it as a buyer’s briefing and not a test report.

Two different ideas of what a book tool does

Aivolut Books is built around generating a manuscript. You set a brief, an audience and a style, review an outline, and it writes the chapters. It also makes a cover and Amazon metadata. The listing pitches a whole book in one click, but its own FAQ says you get a connected first draft that you must review, edit, fact-check and proofread. We believe the FAQ.

AIWriteBook treats drafting as one stage in a longer chain. The listing counts over 45 tools: outlines, characters, an editorial letter, formatting, covers, blurbs, keyword research and launch material. It covers fiction, nonfiction, picture books, coloring books and comics.

So the real question is how much of the job you want in one account. If you only need a draft, Aivolut Books is the narrower fit. If you also need print files and a launch kit, AIWriteBook is the one built for that.

Writing in your own voice

On paper these two are close. Aivolut Books includes custom writing styles on every plan. You can give instructions or upload a PDF, DOC, DOCX or TXT sample, and you can upload your own material to blend with generated text. The FAQ answer on style is cut off in the copy we have, so we can’t say what else it covers.

AIWriteBook asks for a sample of your writing and says every chapter is written to match its voice, rhythm and dialogue. You can edit any paragraph inline or regenerate a weak section. Its nonfiction mode is the more concrete idea. Add your own PDFs, notes or articles as references and chapters are written from them with citations. The first reference file is free and each one after that costs 10 credits.

Here’s our doubt, and it applies to both. Voice matching tends to wobble over tens of thousands of words, and neither listing shows a sample you could judge. Feed either one your own pages inside the refund window and read what comes back.

Covers, metadata and getting onto Amazon

This is where the gap is widest. Aivolut Books generates a cover, an Amazon description, keywords and categories. The listing is inconsistent on delivery. One line says you can publish directly to Kindle Direct Publishing, while another says you generate a Word document and convert it yourself. We’d plan on doing the upload by hand. The FAQ adds that page count depends on your formatting, trim size and images, so print files likely need a human pass.

AIWriteBook lists a print-ready PDF interior, a wrap cover with the spine sized to your page count, and EPUB and DOCX files. It says the print files meet the specs of KDP, IngramSpark, Lulu and Draft2Digital. The cover designer offers 21 art styles and puts your title and author name into the art, at 30 credits per new version.

It also lists keyword research and category selection from live Amazon data, a niche finder, a press kit, ARC review requests and launch graphics. The listing doesn’t say how often that Amazon data refreshes. Treat it as a starting point.

For a KDP publisher, AIWriteBook looks like the stronger kit. Aivolut Books covers the basics but leaves more of the final step to you.

Credits decide what you really pay

Both deals are lifetime access with a monthly credit allowance, and this is where we’d slow down.

Aivolut Books lists monthly credits of 2,000, 1,000, 500 and 200. The columns in its feature table aren’t labeled. By the pattern, the first looks like the biggest plan. The listing never says what a book, a chapter or an illustration costs. Without that, you can’t tell whether 200 credits is one draft or ten. That’s a real gap in a listing for a product you’re meant to rely on.

AIWriteBook is more open. A 20-chapter outline costs 60 credits. Chapters then cost 300 credits on Gemini, 400 on Grok or 600 on Claude. Audiobooks run 1 credit per 12.5 characters, and translation is 15 credits per chapter plus 30 per book. Its monthly figures are 5,000, 2,500, 1,000 and 500, but the listing doesn’t make clear which belongs to which tier. Its feature table also looks inconsistent. Book series support, for example, shows as true, false, false, true across the four plans.

Both let you bring your own API key on some tiers. On AIWriteBook that’s Tier 3 and 4, where every action costs 1 credit and you pay the model provider directly. On Aivolut Books it appears in the first two columns only. That helps heavy users, but it means a running API bill.

Prices, tiers and the fine print

Aivolut Books costs $59, $119, $269 or $499, against list prices of $456, $696, $1,416 and $2,376. The plans are Basic, Starter, Plus and Pro. Word limits per book are listed as 100,000, 10,000, 20,000 and 30,000, an odd sequence you should confirm on the deal page. Audiobooks, deep research and advanced manuscript workflows appear only in the first column.

AIWriteBook costs $79, $159, $319 or $519, against list prices of $144, $360, $1,440 and $2,000. Visual books, translation and bring-your-own-key sit on Tiers 3 and 4, per the listing. Illustrated children’s books will likely push you up the ladder. The public author page with a reader email list is tied to Tier 2 and up.

The terms match closely. You must activate within 60 days, can upgrade while the deal is live, and can only downgrade within 60 days of purchase. AIWriteBook adds a caution: access to future AI models may be discounted or may need an add-on. It also says the deal runs until December 2, 2026. The Aivolut Books listing gives no end date.

Trust, reviews and who should pick which

Aivolut Books has 5 reviews averaging 4.60. That’s pleasant but thin, and AppSumo’s own summary admits some features are still being enhanced. AIWriteBook shows 219 reviews averaging 4.73. Its summary text says 4.6 from over 1,300 reviews, and the two figures don’t match, so read the reviews yourself. That summary also mentions occasional credit consumption issues and interface quirks.

The AIWriteBook demo video doesn’t help much. It’s a founder talking for about a minute, with no screen recording and no walkthrough of the editor, cover tool or export step.

Pick Aivolut Books if you’re a coach, consultant or KDP publisher with plenty of knowledge, little time, and a willingness to edit heavily. It’s cheaper to enter at $59. Just ask the vendor what a book costs in credits before you commit.

Pick AIWriteBook if you’re a self-publisher who wants editing, formatting and launch help alongside the draft, and you value a listing that shows what each action costs. Its larger review base is a mild point in its favor.

Skip both if you want to write every sentence yourself, or need a finished manuscript without editing. Whichever you buy, run a real project through it inside the 60 days and watch how fast the credits go.
