What the AI Visibility Checker is
The AI Visibility Checker is a free public report that measures Answer-Engine Visibility — how often and how prominently your brand appears when large language models answer buyer-like questions in your market. You type brand, domain, industry, and optional competitors; we generate twelve buyer-style prompts, query model APIs for ChatGPT, Claude, Gemini, and Perplexity (not the consumer chat apps), judge each answer, and score the result from 0 to 100 with a letter grade and a five-bar breakdown.
If you searched for an AI brand visibility checker or an LLM visibility checker, you are in the right place. Those phrases describe this same free report — not three separate products. Other keyword titles may point here later; the checker, inputs, engines, and Answer-Engine Visibility metric stay the same.
How it works
Unlike the quick domain-only AI Visibility Score on the suite hub, this checker uses the details you provide. There is no homepage inference step: your brand name, domain, industry, and up to three competitors drive a twelve-query set across all four engines. Each engine answer is judged for mention, position, sentiment, and citation signals from those API responses. Soft-fail cells are marked when a vendor fails so one flaky engine does not void the whole run.
On-screen results are free. Enter an email only if you want the PDF download, which includes the full report chrome plus raw engine answers for deeper review. The same prompt set can carry into AI Brand Monitoring when you are ready to watch trends weekly instead of re-running by hand.
What the Answer-Engine Visibility score means
Answer-Engine Visibility is a 0–100 composite for this run: mention rate, typical ranking position when mentioned, citation presence, and sentiment where the brand appears. The grade and five bars summarize those parts so you can see whether you are invisible, occasionally named, or regularly recommended. Scores move between runs — models update, sampling varies, and the same inputs can produce a different number tomorrow. Treat the report as a directional snapshot, not a deterministic audit certificate.
Do not confuse this metric with crawl-coverage scores from AI bot traffic products. Answer-Engine Visibility only describes how you show up inside model answers for the prompts we asked. It does not measure whether crawlers fetched your pages.

Frequently asked questions
Do I need an account to run the AI Visibility Checker?
No. The on-screen Answer-Engine Visibility report is free and public. Enter your email to unlock the PDF download with all raw engine answers.
What is Answer-Engine Visibility?
It is our 0–100 score for how often and how strongly your brand appears in answers from ChatGPT, Claude, Gemini, and Perplexity for the buyer-like prompts in this run. It is not a crawl-coverage or bot-traffic metric.
Why did my score change when I ran the same brand again?
Answer engines are non-deterministic. Model updates, sampling, and timing mean scores can move between runs even with the same inputs. Use the report as a snapshot and compare trends over time with monitoring if you need a steadier view.
Is this different from an AI brand visibility checker or LLM visibility checker?
No. Those search phrases refer to this same free checker and Answer-Engine Visibility report. We are not shipping three different products under those names.
