Inkfluence AI vs Aivolut Books
For most authors, Inkfluence AI is the better pick. Every book type is on every paid plan, books have no word cap, and the same subscription makes KDP print files, audiobooks in 14 languages and Etsy and Gumroad listings. Aivolut Books unlocks fiction, picture books, audiobooks and translation one tier at a time. Aivolut Books' public plans and terms were read on 19 Oct 2026.
Our verdict: Inkfluence AI
Inkfluence AI is the stronger choice for writing, finishing and selling books. Fiction, picture books, coloring and ABC books, audiobooks and translation are all on the $9.99 Creator plan, books run as long as the story needs, and the same plan makes KDP paperback files and lists your book on Etsy or Gumroad. The free plan needs no card, so you can see a finished book before you pay.
Aivolut Books suits a narrower job: research-led non-fiction drafted from your own uploaded documents, with cited web research on its top tier. To get fiction you need its $29 tier, and picture books, audiobooks and translation need its $49 tier.

Pricing, and What Each Tier Unlocks
The two products price differently. Aivolut Books sells credits and a per-book word cap by tier. Inkfluence AI sells chapters, with images, audiobook chapters and translations as monthly allowances.

Inkfluence AI's own AppSumo deal runs from $49 to $499. Tier 1 is 35 chapters a month and Tier 2 is 80, both with every text book type, fiction included; audiobooks, translation and a picture-book image allowance (50 images a month on Tier 3, 100 on Tier 4) start at Tier 3, with unlimited chapters on Tiers 3 and 4.
What one book costs, with the arithmetic shown
List prices, a full month's allowance spent on one kind of book, and Inkfluence AI chapters at about 1,000 to 1,500 words each. Treat these as ranges.
A 10,000-word non-fiction book
Aivolut Books: 50 credits. Basic's 100 credits make 2 books for $9, so $4.50 each; Pro's 2,000 make 40 for $49, about $1.23 each if you use every credit. Inkfluence AI: 7 to 10 chapters, so Creator's 35 chapters make 3 to 5 books for $9.99, about $2.00 to $3.33 each; on Premium chapters are unlimited.
A 30,000-word book or novella
Aivolut Books: 150 credits, and not possible on Basic or Starter, whose caps are 10,000 and 20,000 words. Plus's 1,000 credits make 6 for $29 (about $4.83 each, and fiction needs Plus anyway); Pro makes 13 for $49 (about $3.77). Inkfluence AI: 20 to 30 chapters, one book a month on Creator at $9.99; Premium at $19.99 has no chapter limit.
A short illustrated picture book
Aivolut Books: a 24-page picture book with its cover is 50 credits on Pro, so up to 40 a month on paper for $49. Inkfluence AI: a story book uses one image per illustrated page, 14 for the default length, with the cover and character sheet not counted. Creator's 20 images cover one such book, Premium's 50 cover three, and each extra picture is 1 chapter credit, $0.50 to $0.67 depending on the pack. At volume, Aivolut Pro is cheaper per picture book.
An English audiobook of a 30,000-word book
Aivolut Books: 300 credits on Pro, 15% of its 2,000 a month, and Pro is the only tier with audiobooks. Inkfluence AI: one audiobook chapter per book chapter, so a 20 to 30 chapter book fits in Premium's 30 a month, or takes Creator's 15 a month across two months, in any of 14 languages.

Book Types and Length
Fiction. Aivolut Books lists 20 non-fiction genres on every plan and 16 fiction genres from Plus up, so the $49 lifetime tier and the $9 and $19 monthly plans write non-fiction only. Inkfluence AI writes fiction on every plan through the AI novel writer, with a story bible and a running record of what each character knows and what has happened, checked before each chapter is written.
Length. Aivolut Books sets a maximum per book on each tier: 10,000, 20,000, 30,000 or 100,000 words. That is a clear number to buy against. Inkfluence AI has no per-book word cap. You do not set a word target; length follows the chapter count, which follows your prompt and outline. The first run plans up to 40 chapters and you can add chapters afterwards.
Short practical formats. Aivolut Books makes guides, checklists and swipe files as "digital products" from Starter up. Inkfluence AI covers them as book types on every plan: a lead magnet, a checklist pack, a workbook, an email course or a business book, 33 book types in all.
Series. Both make connected series, on Aivolut Books from Pro. On Inkfluence AI you continue a book you own from its menu: fiction carries the story bible into the next book, and picture books keep the same characters, art style and page size. The series writer page shows how.
Picture Books, Coloring Books and ABC Books
Aivolut Books' picture books are a Pro feature: 12, 16 or 24 pages, with a choice of age group, story direction and visual style, a character reference you can regenerate for 2 credits, and a review step for text and art. Its pages do not describe coloring books, alphabet books or books made from your own art.
The Inkfluence AI picture book maker makes three kinds of illustrated book. Story books paint 10 to 16 illustrated pages from a character sheet, so the same characters look the same on every page. The coloring book generator makes 12 to 40 line-art pages in three line styles (children's, bold and easy, and detailed). The ABC book maker runs A to Z or 1 to 10, one subject per page. If you draw, you can also turn your own illustrations into a picture book.
The honest trade-off is volume. Aivolut Pro's 2,000 credits buy far more picture books a month on paper than Creator's 20 or Premium's 50 images. Inkfluence AI's picture books come with the parts a printed book needs: a square 8.5 x 8.5 inch trim by default, a bleed interior for KDP and a full-wrap cover.

Publishing and Print Files
Ebook and manuscript files. Both export DOCX, EPUB and PDF. On Inkfluence AI the free plan exports PDF, and EPUB and DOCX come with the paid plans.
Paperback files for KDP. Aivolut Books' AppSumo FAQ says Word-format books can be converted to print-ready PDFs, and each book includes its first cover; trim sizes, bleed and a back-and-spine cover wrap are not stated. Inkfluence AI's KDP package is one download: the interior PDF at your trim size (6 x 9 inches by default) with gutter margins, a bleed interior when art runs to the page edge, a full-wrap cover with the spine width calculated from your page count and paper, the front cover and a Kindle EPUB. Planning a seasonal release? The KDP publishing calendar gives submit-by dates for each holiday.
Amazon listing copy. Both write the description, keywords and categories for the KDP form. Inkfluence AI writes 7 keywords and 3 categories, matching the fields KDP asks for.
Selling outside Amazon. Aivolut Books states that it does not publish for you. Inkfluence AI lists a finished book on your Etsy shop or Gumroad from the app.
Audiobooks and Translation
Audiobooks
Aivolut Books narrates on Pro only, in English only, as one MP3 per chapter or for the whole book, and lets you regenerate passages for 5 credits per 550 words. Its pages do not name the voices or an encoding spec.
The Inkfluence AI audiobook generator is on Creator (15 chapters a month) and Premium (30, with HD voices), with 49 voices in 14 languages. It exports one file per chapter encoded to the ACX audio specification: 44.1 kHz, 192 kbps constant bitrate, mono, with loudness inside the required range. Audible's ACX does not accept AI narration from outside tools, so these files go to stores that accept AI-narrated audiobooks.
Translation and languages
Aivolut Books writes in 30+ languages on every plan and notes that quality varies; translating a finished book of up to 100,000 words into a separate copy is a Pro feature priced in credits (75 credits for 30,000 words).
Inkfluence AI writes natively in 30+ languages, and the book translator turns a finished book into any of 59 languages: 15 books a month on Creator and 40 on Premium. Narration then works in the 14 voice languages, so a translated book can have its own audiobook.
What Aivolut Books Adds on Its Higher Tiers
Three research tools Inkfluence AI does not offer, as of 19 Oct 2026. They matter if you write non-fiction from a pile of your own material; for most books, the brief and the editing assistant do the same job.
- Your own material as the source. Knowledge bases take your notes, interviews and documents (10, 50 or 100 of them, 100 to 500 MB, from Starter), so an authority book can be written from what you actually know.
- Cited web research. Deep Research on Pro writes a research report with cited web sources for 20 credits.
- Writing samples and your own AI key. Custom styles from uploaded samples, and on Plus and Pro, writing on your own AI provider account, billed separately by the provider. Inkfluence AI uses a brief and tone preset, then the assistant rewrites any passage in your voice.
Who Should Choose Which
Choose Inkfluence AI if you
- Write fiction, or might, and do not want to buy a higher tier to start
- Write books longer than a fixed cap, or do not know yet how long they will be
- Want coloring books, ABC books or picture books from your own art
- Need KDP paperback files with bleed and a full-wrap cover

Choose Aivolut Books if you
- Write non-fiction from your own notes, interviews and documents
- Want cited web research built into the drafting

How to Move a Book from Aivolut Books to Inkfluence AI
Aivolut Books exports DOCX, EPUB and PDF; Inkfluence AI imports DOCX, DOC, PDF, EPUB, TXT and Markdown.
- Export the book from Aivolut Books as DOCX. Word files keep headings best.
- In Inkfluence AI, click New Book, then Import content, or drop the file on the prompt box on the Home tab. A manuscript split across several files can come in as one book, in the order you set.
- Inkfluence AI detects chapters from your headings (and from the text itself when there are none), shows you the chapter list, and opens the book in the editor with headings, lists and formatting carried over. The importing help covers PDFs and edge cases.
- Regenerate or rewrite any chapter, add images, design the cover, record the audiobook, translate it, then export the KDP package or list it on Etsy or Gumroad.
