Profound vs Semrush AI Toolkit (2026): price, engines, pick
Profound is an enterprise AI visibility platform sold by contract. Semrush sells AI visibility inside its SEO plans at a public price. They rarely compete for the same buyer.
Stellarcast is our product, so read this knowing our bias. Every vendor fact below was read from the vendor's own pages on 17 October 2026; anything a vendor does not state is marked "not published".
The short answer
Profound publishes no brand price: a free 7-day trial of 50 prompts on three engines, then an Enterprise contract with up to nine engines and an AI Marketer that stages rewritten pages as drafts in your CMS. Semrush publishes everything: $139 a month for the SEO plan with AI search tracking, $199 for Starter with 50 prompts a day across Google Search, ChatGPT, Perplexity and Gemini, 7-day trial, cancel anytime. If you need procurement-grade depth, agents and nine engines, Profound. If you want a public price and AI visibility next to your SEO data, Semrush.

Where Stellarcast fits
Profound publishes to your CMS; Semrush does not. Neither publishes a method for deciding that a change caused a lift. Stellarcast checks six engines daily on every paid plan from $39 a month (Google AI Overviews, ChatGPT, Gemini, Perplexity, Google AI Mode and Microsoft Copilot). From $89 it sends the fixes you approve to WordPress as drafts, and from $249 every lift claim is labeled MEASURED, LIKELY or TOO-EARLY with a P25 to P75 range, across 27 markets measured with native-language prompts.
