Built by authors who got tired of spreadsheets.

We started where you probably are: Amazon Ads open in one tab, KDP reports downloading in another, and a spreadsheet in the middle trying to make the two talk. Every month the same evening lost to it, and at the end of it still no clear answer to the only question that mattered — which books were actually profitable.

The tools we tried each took one half. Royalty trackers ignored what we spent. Ads tools were built for FBA sellers and had never heard of KENP page reads or a 35% royalty band. Nothing put spend and earnings on the same screen, so we built the thing that does.

SelfPub Go is a desktop app for macOS and Windows. It reads your Amazon Ads data and your Kindle Direct Publishing reports and shows what your ads cost and what your books earn, per book and per marketplace — ad numbers hour by hour rather than one figure a day late. It also runs the campaigns: create them, re-bid them, clean them up. That is the whole product.

It is not a writing tool and it does not publish or format anything. Those are real problems and other people solve them. We work on the money.
