Self Publishing Titans (SPT) and Univers Studio are both popular tools for Amazon KDP publishers in 2026, but they serve very different purposes. SPT is built around Amazon data — keyword research, BSR analysis, trademark checking, and niche validation via a Chrome extension that overlays Amazon itself. Univers Studio is built around content creation — AI coloring pages, puzzle generators, KDP cover design, and interior formatting.
This comparison breaks down every feature, every price point, and every use case so you can make an informed decision. No fluff, no affiliate bias — just a clear, honest analysis.
What Is Self Publishing Titans?
Self Publishing Titans is a web-based platform plus Chrome extension designed for Amazon KDP publishers who want to make data-driven publishing decisions. Its core strength is real-time Amazon analysis: the Chrome extension overlays keyword metrics, BSR data, and niche validation directly on Amazon search results pages.
SPT's key features include keyword research with search volume and competition data, BSR analysis, a trademark checker to avoid legal issues, niche validation scores, and some puzzle generators for basic content creation. The Chrome extension is what sets SPT apart from most competitors — you can research niches without ever leaving Amazon.
SPT also includes a set of puzzle generators (word searches, sudoku, and a few others), but these creation tools are secondary to the research and analysis features.
Pricing: $14/month (Starter) to $44/month (Titans Pro). No free tier available.
