Self-Publish Toolkit

Self-Publish Toolkit is a web-based platform offering 15+ tools designed for Amazon KDP (Kindle Direct Publishing) authors. It covers the full publishing workflow: finding profitable niches, estimating royalties, generating book cover templates, researching keywords, analysing competition, and tracking keyword rankings. Free tools require no account; Lite and Pro plans unlock advanced research and AI-powered features.

The Free plan gives unlimited access to six core tools — Cover Generator, Royalty Calculator, BSR Estimator, Category Finder, Deal Planner, and Troubleshooter — at no cost. The Lite plan ($6.99/mo) adds 50 monthly credits for keyword research, competition analysis, niche discovery, and listing generation. The Pro plan ($17.99/mo) includes 200 monthly credits and unlocks the Keyword Rank Tracker, Competitor Discovery, and Listing Optimizer.

Enter your book's list price, trim size, page count, and marketplace (US, UK, EU, etc.). The calculator applies Amazon's current printing cost formula and royalty rate (35% or 70%) to show your net royalty per sale and estimated monthly earnings at different sales volumes.

BSR (Best Seller Rank) is a number Amazon assigns to every book — the lower the number, the more copies it's selling. The BSR Estimator converts any BSR number into an estimated daily and monthly sales figure. This helps you gauge the true demand in a niche before investing time writing a book.

Use the Niche Navigator (Lite/Pro) to browse 200+ pre-researched KDP niches filtered by competition level, estimated monthly revenue, and keyword demand. Combine it with the Competition Analyzer to study the top 10 books in any niche — their BSR, review count, and listing quality — so you can identify gaps you can realistically win.

Yes. Subscriptions are month-to-month with no long-term contract. You can cancel from your account settings at any time. You keep access to your plan's tools until the end of the current billing period.

There is no time-limited free trial, but the Free plan gives you hands-on access to six tools with no payment details required. This lets you evaluate the platform before deciding whether the Lite or Pro research tools fit your publishing workflow.
