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, per marketplace, in real time rather than a day late. 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.
One question, answered properly
Am I making money on this book? Ads on one side, royalties on the other, profit at the end. We would rather answer that question well than answer twelve of them badly.
Your data stays on your machine
Royalty data lives in a local database on your computer. This niche has watched tools shut down and take the history with them — we would rather you never have to care whether we are still here.
Numbers, not adjectives
ACOS, KENP, BSR, spend, royalty, profit. The audience knows these words. We do not need to dress them up, and a superlative has never fixed a losing campaign.
We say what we have not built
Writing, formatting, distribution, a services marketplace — not ours today. Some of it is on the roadmap and labeled as such. Nothing on this site is a feature you cannot open in the app.
We are looking for the first twenty.
SelfPub Go is in closed early access. If you publish on Amazon and spend on ads every month, tell us about your catalog — it takes about thirty seconds.
