Free AI visibility checker
AI visibility is two things: whether AI crawlers can read your site, and whether the assistants name you when buyers ask. GEOFast checks the first in about a minute with no account, then puts three of your buyers' questions to ChatGPT, Perplexity and Gemini and shows who they named.

What the AI visibility checker checks.
- 01
Reads your site as AI crawlers do
robots.txt for 13 AI crawlers, live fetches as 4 of them, and up to 300 pages read with and without JavaScript.
- 02
Drafts your buyers' questions
Three questions a buyer would ask before knowing your name, written from what your pages say you sell. This step needs no email, and a free account lets you edit them.
- 03
Asks ChatGPT, Perplexity and Gemini
Each question once on each assistant. A free account asks six questions once each, 18 answers in all.
- 04
Shows who they named
How many answers named you and which other brands they named, with every answer in full.
What each verdict means.
- Score
0 to 100, from whether AI crawlers can reach your site, search engines can index it and crawlers can read it without JavaScript, plus a small share from our model's read of your content. It says nothing yet about what the assistants answer.
- Named
The answer mentioned your brand. The report counts these out of the answers asked, and shows each answer.
- Other brands
The other brands the answers named, with how many answers named each.
- A sample
The X-ray's answers, and a free account's 18, show which way things lean. They can't hold a rate steady: ask again and the count moves.
Questions about the AI visibility checker.
What is AI visibility?
How often AI assistants such as ChatGPT, Gemini and Perplexity name your brand when people ask the questions your buyers ask, and whether their crawlers can read your site in the first place. A site they can't read can still be named from what the rest of the web says, but it can't be quoted. What GEO is
How does the AI visibility checker work?
It runs GEOFast's free X-ray on your site, then puts three of your buyers' questions to ChatGPT, Perplexity and Gemini once each, with no email or account. A free account asks six questions once each, 18 answers. The report shows every answer, how many named you, and which other brands were named.
Is this the same as asking ChatGPT myself?
It asks with nothing of yours behind the question: ChatGPT and Gemini are read from their apps signed out, Perplexity through its API, each question once on each. One chat of your own can name different brands the next time you ask, and it knows what you asked before. Check ChatGPT by hand
How accurate is a free AI visibility check?
It's a first look. 18 answers are too few to hold a rate steady, which is why the report calls them a sample. Tracking the same questions on a schedule, with a range on every rate, is what GEOFast's paid plans do. Why answers change
Is an AI visibility checker the same as a GEO audit?
They are two halves of one X-ray. The GEO audit is the half about your site: which checks pass, and the fixes ranked by impact. The AI visibility check is the half about the answers: what the assistants said when asked your buyers' questions. The free GEO audit
Do I need an account?
Not for the site check or its first answers. A free account, made with Google or a code sent to your email, adds 18 answers and every fix.
Is the AI visibility checker free?
Yes. It's part of GEOFast's free X-ray: no account, nothing to install, and most X-rays finish in under a minute.
