An AI visibility checker tests whether AI engines name and recommend your business. Learn how one works, how to check for free, and how to read your score.

You keep hearing that customers now ask AI assistants who to hire before they visit a website. The obvious next question is simple. When someone asks, does the AI name your business, or does it hand the customer to a competitor? An AI visibility checker answers that question with data instead of a guess. It runs the prompts your customers use, reads the answers, and tells you where you stand.
An AI visibility checker is a tool that runs your target questions against the AI engines your customers use and reports whether your business is named, cited, and recommended in the answers. Most return a score plus a prompt-by-prompt view of where you appear and where you go missing.
A checker is a diagnostic. You give it the questions that matter for your business, it asks those questions of the AI engines, and it reports the result. The output is usually two parts: a headline score that sums up your presence, and a detailed list showing, prompt by prompt, whether you appeared and how you were described. Some checkers add competitor comparison, so you see who wins the answers you lose.
The word "checker" covers a range. A free one-click tool gives you a quick read on one or two prompts. A full audit tests many prompts across several engines and explains the causes behind the score. Both answer the same core question, at different depth.
Under the hood, every checker runs the same loop:
The quality of a checker comes down to the prompts and the engines it covers. A checker that tests one generic prompt against one engine tells you far less than one that tests your real buyer questions across the engines your customers actually use.
You do not need to buy anything to get a first read:
That manual pass is a real checker, run by hand. To get a scored baseline without the manual work, run a free audit and see how the AI engines describe your business today.
A score is a baseline, not a grade. Treat it as the number you improve. Read the prompt-level detail underneath it, because that is where the work lives: the prompts where you are absent, the answers that state wrong facts, and the competitors taking the recommendations you want. Fix the causes behind those prompts, your website, listings, reviews, and cited sources, then recheck to confirm the score moved.
For the full AI Visibility Snapshot, the score comes with the causes and a fix list, so you know what to change.
