Transparency
No black boxes. Every adjustment our automation suggests comes with clear reasoning and performance data.
Excellence
Purpose-built for the unique economics of Kindle Direct Publishing, from royalties to KENP read rates.
The Story Behind Uool
Uool.io started as a series of custom scripts used by a small group of high-volume Amazon publishers. They were frustrated by the lack of tools that understood the "long-tail" nature of book advertising.
Standard advertising platforms focus on e-commerce ROI. But for an author, a click on an ad doesn't just mean a sale; it means a potential lifelong reader, a newsletter sign-up, and KENP royalties that take weeks to fully realize.
We decided to turn those scripts into a platform that any author could use. A platform that treats every book like the unique business it is.
