Desktop suite that automates your entire self-publishing pipeline: formatting, cover validation, EPUB compliance checks, AI-assisted keyword research, royalty calculations, and licensing — in 5 languages. Built by an indie publisher tired of manual prep work across Amazon KDP, Google Play Books, and StreetLib. One-time payment, no subscription. Windows desktop app with a clean, modern interface designed for authors and small publishers managing multiple titles.

Hey, I'm Roberto — an independent self-publisher based in Italy. For years I've been publishing nonfiction ebooks across Amazon KDP, Google Play Books, and StreetLib, and I kept hitting the same wall: every platform has different cover specs, different EPUB requirements, different metadata rules. I was spending more time on formatting and compliance than actually writing. So I built PublishWizard for myself first — a desktop tool that validates covers against each platform's specs, checks EPUB compliance before upload, calculates royalties across formats, and even helps with keyword research using AI. Over time it grew into something I thought other self-publishers might find useful too, so I packaged it up as a standalone product. It's not trying to be a writing tool — it's the unglamorous pre-launch checklist automated, so you can focus on the next book instead of fighting upload rejections. Happy to answer any questions about how it works!

The cover validation alone saved me an embarrassing amount of back-and-forth with KDP last week. Clean interface, no clutter, and refreshing to pay once instead of being locked into another subscription.

Finally a desktop tool that actually handles EPUB validation without making me jump through five dialogs. The royalty calculator across multiple stores is a quiet lifesaver for tracking small titles.

The EPUB compliance checks alone are worth the price - so many indie authors skip those and get caught by Amazon later. Nice to see an indie publisher actually build the tool they wished existed.
