Comparison
ebookdone vs CoAuthor.ai
TL;DR
CoAuthor.ai is an ambitious AI book platform aimed at publishers and thought leaders, priced as a subscription: $65/month for basic tools, $299/month for 3 book credits a month, $999/month for 10. That works out to roughly $100 per book on their Pro plan, and the credits reset monthly. ebookdone produces a complete KDP-ready book, print files and metadata included, for $9 flat, and credits never expire. If you run a publishing operation shipping 10+ books every month with a team, their tooling depth may earn its price; for everyone else the math is not close.
CoAuthor.ai is one of the more capable AI book platforms: market research pulled from Amazon data, an outline builder, section-by-section drafting with editing agents, one-click covers, and formatting aimed at KDP, Apple Books, IngramSpark, and Draft2Digital. Their pitch is "Create a Bestseller in Hours," aimed at publishers and personal brands. The difference is the business model. CoAuthor sells monthly subscriptions from $65 to $999, with actual book generation credits starting on the $299/month Pro plan at 3 books a month, credits that reset with the billing cycle. ebookdone charges $9 for one book, $24 for three, $69 for ten, whenever you get around to using them, and every book ships with the KDP paperback files: a 6x9 interior with gutter computed from your page count and a full-wrap cover with computed spine. We also promise you a publishable book, not a bestseller; nobody can honestly promise you a bestseller.

Pick CoAuthor.ai if…
Pick CoAuthor.ai if you are a publishing operation shipping many books every month with a team, and features like Amazon market analysis, editing agents, and 50k-word manuscripts matter more than per-book cost. At the $999/month tier producing 10 books a month, their per-book price approaches $100 with tooling wrapped around it, and for a staffed publishing business that may be a fair trade.
Pick ebookdone if…
Pick ebookdone if you are publishing at your own pace and paying with your own money. One $9 credit returns every file KDP asks for, the credit you buy today still works next year, and you can read a complete unedited sample book before spending anything. Their entry plan’s first month costs more than five complete books here.
Don't take our word on quality — read a complete, unedited book our pipeline produced: 18,648 words, cover to back matter.
FAQ
How much does CoAuthor.ai cost?
As of their beta pricing (July 2026): $65/month for the entry plan with basic tools and 3 covers a month, $299/month for Pro with 3 book credits a month, and $999/month for Business with 10 books a month, with a 25% beta discount and a stated price increase coming at public launch. ebookdone has no subscription: $9 for one book, $24 for three, $69 for ten.
Is ebookdone cheaper than CoAuthor.ai?
By roughly 10x per book. CoAuthor’s Pro plan works out to about $100 per book if you fully use its 3 monthly credits; ebookdone is $9 per book or $6.90 each in the 10-pack, and unused credits never expire. Their entry $65/month tier does not include book generation credits at all.
What does CoAuthor.ai have that ebookdone does not?
Two real things: editing agents for deeper post-draft refinement, and manuscripts up to about 50,000 words versus our ~30,000. Their market analysis goes deeper on competitor data, though ebookdone now includes a free niche check with live Amazon demand data at book creation. Whether those are worth a monthly subscription at their prices depends entirely on your volume.
Can either tool guarantee a bestseller?
No, and you should be wary of any tool whose headline implies it. Sales depend on niche selection, competition, and marketing. What a tool can guarantee is publishable files: both products produce books you can upload, ours for $9 with the complete KDP print and metadata pack included.
Can I try both before paying?
ebookdone, yes: free editable outline, complete first chapter, and a watermarked preview with no credit card, plus a public unedited sample book. CoAuthor.ai currently lists no free book preview; its cheapest entry is the first month of the $65 plan (about $48.75 with their beta discount).
Try it free — outline plus your full first chapter, no card required. Then $9 per book.
