The short answer

AI-visibility tools fall into two shapes. Score-based monitors — Profound, Otterly, Peec AI, Ahrefs Brand Radar, Semrush AI Search Visibility, Scrunch AI — track prompts you choose and return a 0–100 visibility score plus sentiment and share-of-voice trends. They are strong for ongoing monitoring and reporting. Reverse AI search is the other shape: you enter a domain and get the actual query list ChatGPT already cites it on — each with its intent and the competitors cited beside it (Gemini and Grok are on the roadmap). The honest rule of thumb: pick a score-based monitor if you want a number to watch over time, and pick reverse AI search if you want the list of prompts to act on. Mentn is the reverse-search option, with a free Domain Check at /tools/ai-citation-checker.

What is the core difference between AI-visibility tools?

Almost every product in the category answers one of two questions. A score-based monitor answers “how am I trending?” — it samples prompts and hands back a number, sentiment and share of voice over time. Reverse AI search answers “exactly which queries pull me in?” — it returns the underlying list of prompts your domain is cited on, plus the rivals cited alongside you. Both are legitimate; they simply produce different outputs. The full background is in how reverse AI search works.

Stop comparing in the abstract and look at your own data. The fastest way is to run a free Domain Check at /tools/ai-citation-checker — enter your domain and read back the actual queries ChatGPT already cites you on, with the competitors cited beside you. Then you can judge any tool by whether its output helps you act on that list.
