Verdict
Book Bolt is the broader and cheaper subscription. At $23.99 a month, or $19.99 billed yearly, Pro bundles keyword research, a drag-and-drop designer for covers and interiors, puzzle generators and 1,000 AI credits. For a publisher running journals, puzzle books and coloring books side by side, that breadth is hard to match, and BookIllustrationAI does not try to.
BookIllustrationAI costs more because it does one job start to finish: it generates the pages of a coloring book in one style and assembles the KDP interior. On Builder, $79 a month for 74 credits, a 40-design book plus its cover is 41 credits, so 1 full book a month with room for re-generations. Publisher’s 200 credits cover 4. Book Bolt does not publish how many credits an AI image uses or the resolution it comes out at, so its 1,000 credits cannot be turned into a page count from its own site.
The practical test: if coloring books are the whole catalogue and your time goes into making pages, a dedicated generator earns the price gap. If coloring books are one product line among several, Book Bolt’s bundle is the better value.
Frequently asked questions
- How much does Book Bolt cost?
- As of 19 September 2026, Book Bolt’s pricing page lists two plans. Pro costs $23.99 billed monthly, or $19.99 a month billed yearly, with 1,000 AI credits a month. Premium costs $35.99 billed monthly, or $29.99 a month billed yearly, with 4,000 AI credits, premium graphic packs and early access to beta features. Both start with a 3-day free trial that includes real exports.
- Does Book Bolt still have a $9.99 Newbie plan?
- Not on its pricing page as of 19 September 2026, which lists Pro and Premium only. Reviews that quote a $9.99 Newbie plan describe an earlier price list. Book Bolt changes its plans, so check the pricing page itself before you budget around a number from a review.
- Can Book Bolt make coloring pages with AI?
- Yes. Book Bolt Studio includes an AI image generator that it says creates “characters, vibrant story illustrations, coloring pages, and more”, paid for with the AI credits on your plan. Book Bolt does not publish how many credits one image uses, the resolution the images come out at, or whether the pages of one book share a style, so test those in the free trial before you plan a 40-page book around it.
- How many coloring books does each BookIllustrationAI plan make?
- One credit generates one page or one cover, so a 40-design book with its cover is 41 credits. Builder ($79 a month) includes 74 credits: 1 full book a month, with 33 left for re-generations and edits. Publisher ($129 a month) includes 200: 4 full books. Starter ($39 a month) includes 29: a book of up to 28 designs plus its cover.
- Is there a free trial?
- Book Bolt has a 3-day free trial with full access, cancellable before you are charged. BookIllustrationAI has no free plan or trial: every plan is paid upfront. The free KDP tools on this site, such as the coloring page prompt generator and the KDP specs calculator, need no account.
- Which is better for KDP coloring books, Book Bolt or BookIllustrationAI?
- If coloring books are your whole catalogue, BookIllustrationAI: it generates every page of a book against one style reference and assembles the 300 DPI interior with blank backing pages for you. If you also publish journals, planners and puzzle books, Book Bolt covers more ground for less money and adds keyword research with Amazon search volume.
