Keyword Magic Tool draws on more than 28 billion keywords across 142 regional databases, Keyword Overview scores any term for value and competition, and Keyword Strategy Builder turns a keyword list into a content plan of topic clusters. Prompt Research adds a view of what people ask AI assistants, which helps teams plan for AI answers as well as search. The pricing page is specific about tiers: the $139 SEO plan includes basic keyword research and competitor analysis, while Starter SEO + AI Search at $199 lists keyword research and optimization tools, and Pro+ at $299 adds historical data and keyword cannibalization analysis. A free plan with 10 reports a day and a 7-day trial make testing easy. Extra seats from $45 a month raise the cost for larger content teams.
