Inkario is a self-publishing studio for Amazon KDP: score a niche, make the book, fix the listing that sells it, and see royalties minus ad spend per title.
Hey Product Hunt! I'm Hosni, the maker of Inkario. I built it after seeing KDP authors piece together niche research, writing and illustration, formatting, listing optimization, and revenue tracking across separate tools. Inkario connects that workflow: validate an idea, create the book and cover, export PDF or EPUB, improve the listing and ads, and see royalties minus ad spend per title. The goal is fewer spreadsheets and handoffs, and more time making books. I'd love to hear which part of the publishing workflow is currently the biggest pain for you.
