The largest self-publishing market in the world. AI is allowed with disclosure, you keep your rights, and Kindle Unlimited pays per page read, which rewards exactly the kind of bingeable serialized fiction our AI is built to write.
Kindle Unlimited readers devour series. The genres with the deepest binge behaviour, and the strongest fit for a multi-book run, are these.
Contemporary, billionaire, second-chance, and small-town. The biggest KU category by far.
Werewolf, vampire, and fated-mates romance with strong series read-through.
System, dungeon core, and cultivation. A huge, hungry KU audience.
Cozy mystery series and fast psychological thrillers built for binge reading.
Space opera and progression sci-fi with loyal, completion-driven readers.
High-tension, high-heat series that keep readers turning pages.
Two streams that stack. On direct sales you earn a 70% royalty in the $2.99 to $9.99 range, or 35% outside it. On top of that, enrolling in Kindle Unlimited earns a share of a monthly fund based on pages read, currently around half a cent per page. KU rewards books readers finish, so the hooks and cliffhangers our AI writes translate directly into page-read income.
AI-generated fiction is explicitly allowed as long as you disclose it at upload. There are no genre restrictions, each book in a series can be enrolled separately, and the page-read model favours exactly the high-completion, series-driven writing our tool produces.
KDP Select gives you Kindle Unlimited, but it requires 90 days of digital exclusivity, so you cannot publish that ebook anywhere else during the term. The AI disclosure is mandatory. New accounts are limited to three new titles per day, which is a spam limit, not a quality bar. And competition in popular genres is fierce, so covers, blurbs, and a real series strategy matter.
