Free AI visibility checker: is your brand cited in AI answers?
An AI visibility checker, also called an AI search visibility checker or LLM visibility checker, runs test prompts through AI search engines and reports whether your brand gets named in the answers. Enter your domain below and this one checks ChatGPT, Google AI Overviews, Google AI Mode, and Perplexity in about 2 minutes.
It queries the engines directly. That is different from the free checkers that only inspect your robots.txt and schema markup and tell you whether AI could find you.

What an AI visibility checker measures
Three numbers, and the third is the one most tools blend away.
Mention rate
The share of test prompts where an engine names your brand. The single number that tells you whether you are in the conversation.
Citation sources
Which domains each engine pulled from to build its answer. This is who the engine trusts in your category, and it is often not you.
Engine coverage
Your result split per engine. Strong in ChatGPT and absent from Perplexity is a common and very actionable pattern.
What is an AI visibility score?
An AI visibility score is a single number, usually out of 100, that a tool uses to summarise how often and how prominently AI engines name your brand.
How tools calculate one
A tool runs a set of prompts, scores each answer on whether and how prominently your brand appears, and scales the total to a single number. Each vendor picks its own prompts, engines and weights, so a score from one tool cannot be compared with a score from another.
Why this checker shows no single score
A blended number hides the thing you need to act on. A brand can be named in most ChatGPT answers and in none from Google AI Overviews, and an average of the two looks like a middling result on both.
The number it gives you instead
How many answers name you, out of the answers that came back (up to 80: 10 questions, each asked twice on 4 engines), broken out per engine, next to the competitors named in the same answers. Questions where Google shows no AI Overview, and answers that fail to load, are left out rather than counted as misses.
Example: if ChatGPT names you in 16 of its 20 answers, Perplexity in 8, and the two Google surfaces in none, you are at 24 of 80, or 30%. The per-engine split is the useful part: it says where to work first.
How accurate is an LLM visibility checker?
Accurate as a count, unreliable as a single answer. An LLM visibility checker is only as good as the number of answers behind it, because the engines do not give the same answer twice.
We measured this on our own checker before deciding what the report should show. Ten brands, five buyer questions each, four engines: 200 answers. We ran it on 2 November 2026, again 3 hours later, and again 2.6 days after that. Here is what held.
| What the check reports | What happened on a re-run | What it means |
|---|---|---|
| One answer: named or not | Flipped in 16 of 168 answers that came back both times, 3 hours apart | A single answer is a coin with a bias, not a verdict. This is what a manual check gives you. |
| Named in X of N, per brand | Moved by a median of 1 and at most 3, out of roughly 16 answers per brand | The count is usable. Read a change of 2 as noise. |
| Top 5 competitors named | 4 or 5 of the same 5 for 9 of 10 brands | Who the engines prefer in your category is the steadiest thing a check measures. |
| Exact pages cited, same question and engine, 2.6 days later | Perplexity 66%, ChatGPT 40 to 44%, Google AI Mode 15 to 18%, Google AI Overviews 14 to 16% | Google's cited pages mostly change within days. Never optimise for one day's source list. |
So we ask each question twice and report how many answers name you. A person checking by hand in ChatGPT reads one answer, which is the row that flipped one time in ten.
One thing went wrong along the way. The first run lost 22 of its 50 Google calls to an error from our data provider, and the script counted every one of them as “no AI Overview”. Nothing looked broken. Brands simply appeared to be missing from Google. Retrying each call up to three times cut the failures to 5 of 50 on the next run and 2 of 50 on the one after, and the report now leaves a failed answer out of the count instead of scoring it as a miss.
Our opinion, which the sample cannot prove: a one-day source list is close to worthless on Google's two AI surfaces, and anyone selling you a “top cited pages” ranking from a single check is selling noise. A page cited by two or more engines for the same question is different. Those were cited again 77 to 91% of the time days later (52 and 56 pages across the two re-runs), so that is where to look first. One test, 50 questions, 10 brands: treat these as a reading, not a law.
Checker, audit, or tracker: three tools, one name
Search for an AI visibility checker and you get three different products. Knowing which one you are running saves you from acting on the wrong answer.
Readiness audit
Could AI find me?
Inspects your site: robots.txt rules, GPTBot access, schema markup, whether an answer can be extracted from your pages. Never queries an engine.
Useful for diagnosis. Does not measure visibility.
Answer check
Does AI cite me?
Sends real prompts to real engines and records who gets named. Measures the outcome rather than the preconditions for it.
What this page does.
Visibility tracker
Is it improving?
Re-runs the same prompts on a schedule and charts the trend, with competitor share of voice over time.
The paid RankScope platform.
We ran 16 of these tools on the same brand in the same week and recorded what each one measured and what it asked for first: free AI visibility tools, tested.

The pages behind the answers
The sites the answers cite, who is listed on them, and three fixes ranked from what the check found.
Why you need an AI visibility checker in 2026
Traditional SEO tells you where you rank on Google. It does not tell you whether ChatGPT recommends your product, whether Perplexity cites your brand when someone asks for the best tool in your category, or whether Google AI Mode knows you exist.
High-intent queries such as “best CRM for small teams” or “top AI chatbot platforms” are increasingly answered in place, with no click to anyone. The brands named in those answers capture the demand that used to arrive through organic search.
Google AI Mode deserves its own mention, because most free checkers skip it. It is a separate surface from AI Overviews, with its own answers and its own sources, and a brand can be present in one and missing from the other. This checker covers both.
A check gives you the baseline: are you in the conversation or not? If you are not being cited, GEO (Generative Engine Optimization) is the discipline that fixes it, and the LLM SEO tools comparison covers the platforms that measure it continuously.
Free check vs. ongoing tracking
Paid plans start at $49/month, or $39/month billed annually. Starter covers ChatGPT and Google AI Overviews; Professional and Agency add Perplexity and Google AI Mode. Full pricing →
Frequently asked questions
What is an AI visibility checker?
An AI visibility checker is a tool that runs test prompts through AI search engines and reports whether your brand is named in the answers. It measures three things: how often you are mentioned, which engines mention you, and which competitors appear in your place. It is the AI-answer equivalent of checking where you rank on Google.
How do I check my brand's AI visibility?
Enter your domain above. The checker reads your site and proposes 10 buyer questions, which you can edit and set to a country (18, including Germany, France, Spain, the Netherlands, the Nordics, Türkiye, Brazil and Mexico, each asked in its own language). It asks each one twice on ChatGPT, Google AI Overviews, Google AI Mode, and Perplexity, and returns a per-engine breakdown of who got named and whether it held across both runs. It takes about 2 minutes and needs no account.
What does an AI visibility checker measure?
Three numbers. Mention rate: the share of test prompts where an engine names your brand. Citation sources: which domains the engine pulled from when it answered, which tells you who it trusts in your category. Engine coverage: your result broken out per engine, because a brand strong in ChatGPT is often invisible in Perplexity.
Are all free AI visibility checkers the same?
No, and the difference is easy to miss. Two different products share the name. A readiness audit inspects your site — robots.txt, GPTBot access, schema markup, page structure — and tells you whether AI engines could find you. An answer check queries the engines and tells you whether they do cite you. Both are useful, but only the second one measures visibility. RankScope's checker is an answer check.
Which AI engines does the checker cover?
ChatGPT, Google AI Overviews, Google AI Mode, and Perplexity. Google AI Mode is the one most free checkers leave out, and it is a separate surface from AI Overviews with its own answers and its own sources.
What is the difference between an AI visibility checker and an AI visibility tracker?
A checker is a one-off snapshot: run it now, see where you stand today. A tracker re-runs the same prompts on a schedule and shows the trend. You want a checker to get a baseline and find out whether you have a problem, and a tracker once you are doing work you need to measure. This page is the checker; RankScope's paid plans are the tracker.
How can I check my AI visibility score?
Enter your domain in the checker above. It asks 10 buyer-intent questions twice each across ChatGPT, Google AI Overviews, Google AI Mode and Perplexity, 80 answers in all, and shows how many of them name your brand, per engine. For example, named in 24 of 80 answers is 30%. Questions where Google shows no AI Overview, and answers that fail to load, are left out of the count rather than counted against you. It is free and needs no account.
What is a good AI visibility score?
There is no universal benchmark, and any tool quoting one is inventing it. What is meaningful is your mention rate relative to the competitors named in the same answers. If rivals are named in most answers and you are named in none, that gap is the finding, not an absolute number out of 100.
Why isn't my brand showing up in AI answers?
Usually one of three reasons. AI crawlers cannot reach your content. Your pages cover the topic but are not structured so an answer can be extracted from them. Or the engines are citing third-party sources — listicles, reviews, forums — that do not mention you. The checker tells you which by showing the domains the engines cited instead.
How accurate are LLM visibility checkers compared with checking answers manually?
A manual check is one answer, and one answer is the least reliable thing you can read. When we asked the same 50 questions on four engines twice, 3 hours apart, whether a brand was named flipped in 16 of the 168 answers that came back both times. The count across many answers held much better: named in X of about 16 moved by a median of 1. That is why this checker asks each question twice and reports a count, not a yes or no. Typing a question into ChatGPT yourself is fine for a look, but do not decide anything on it.
What is the best LLM visibility checker?
It depends on what you need to know. For whether ChatGPT, Google AI Overviews, Google AI Mode and Perplexity name you right now, with no signup, this checker was the most complete of the 16 free tools we ran on one brand in the same week. Honeyb was the fastest, on Gemini only. Verticality sent the largest report, 387 answers, by email the next day. We make this one, so read the full comparison, including where it loses, before taking our word for it.
Is this an AEO checker or a GEO checker?
Both. AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) describe the same discipline of optimizing for visibility in AI-generated answers. This tool measures current performance whichever term you use.
Is the AI visibility checker really free?
Yes. No account, no credit card, no signup. Enter your domain and get the full report. For recurring monitoring across more prompts, RankScope plans start at $49/month, or $39/month billed annually.
Can I check competitors as well as my own site?
The free report names the competitors that appeared in your prompts, so you see who is occupying the answers you want. Running a competitor's domain through the checker directly works too — the tool has no login, so nothing stops you benchmarking against them.
Why does it matter which engine cites me?
ChatGPT and Perplexity have very different source preferences, and Google AI Mode differs again from AI Overviews. A brand can be well cited in one and absent from another. A single blended score hides that, and hiding it leads to optimizing the wrong thing.
