Summary
Helium 10 is built for sellers of physical products: most of the plan covers FBA product research, inventory, refunds, ad automation and TikTok Shop. For a KDP publisher the useful parts are Cerebro (reverse-ASIN keyword lookup, which now includes the former Magnet keyword tool) and the Xray Chrome extension for sizing up competing books, and Helium 10 publishes its own KDP guides for these. Independent testing reports that Cerebro returns far fewer keywords for Kindle ebook ASINs than for paperbacks, so it is weaker for ebook-only publishers.
