Amazon Ads Weren't Built for Indie Authors
You write books. You shouldn't have to be a full-time data scientist just to run profitable ads.
Drowning in Spreadsheets?
Downloading Search Term reports, running pivot tables, and manually adjusting bids takes hours away from writing your next book.
Bleeding Budget on Bad Clicks?
Amazon gladly takes your money for clicks that never convert to pages read or book sales. Your profit margins are silently shrinking.
Tired of Guessing Your Royalties?
Flipping between the KDP dashboard to check borrows and the Amazon Ads console to check spend makes calculating true profit impossible.

“Finally a tool that understands KDP authors. I don't need enterprise features I'll never use — just smart automation for my book ads. It's exactly what I was looking for.”
