Frequently asked questions

What authors ask before using the tools.

Are these self-publishing tools free?

Most of the tools — the calculators, generators, and checkers — are completely free to use. A few offer an optional paid upgrade, such as a detailed AI report or an automated file fix, and those are clearly labelled on each tool.

Do I need to sign up or create an account?

No account is needed for the core calculators and generators. A small number of tools ask for an email to send results or unlock a free detailed report, but there is no paywall to get started.

What tools does a self-published author actually need?

Most authors start with a royalty or print-cost calculator to model pricing, keyword and category research for Amazon discoverability, a description generator for the listing, and an EPUB validator before upload. The hub groups every tool by Writing, Marketing, Pricing, Publishing, and Design so you can find the right one fast.

Are the KDP royalty and print-cost calculators accurate?

They use Amazon KDP's published royalty and printing formulas, and the data behind them is the same our team uses across 10,000+ books. Treat the outputs as close working estimates — Amazon's exact figures can vary slightly by marketplace and date.

Can I use these tools for IngramSpark, not just Amazon KDP?

Yes. The royalty and cover-template tools support IngramSpark and other print channels alongside Amazon KDP, so you can compare outcomes across platforms before you commit.
