What a free AI visibility checker tells you
A checker sends a few buyer questions about your category to AI engines and reports whether your brand appears. It is the fastest way to learn if ChatGPT knows you exist.
It is a snapshot. AI answers change from one run to the next, so one check can miss you or flatter you. Run it again in a week, or use a tracker if the result matters to your business.
What to do if you are not mentioned
AI engines repeat what the web says about your category. To get mentioned, publish pages that answer buyer questions in the first lines, compare you honestly with alternatives, and include FAQs and schema. Get listed on the review and comparison sites the engines already cite.
If you do not have time to write those pages, GrandRanker writes and publishes them for you, then re-checks your visibility.
How we compared them

FAQ
How do I check if ChatGPT mentions my brand?
Use a free AI visibility checker such as the GrandRanker checker (https://grandranker.com/free-tools/ai-visibility-checker). It asks ChatGPT, Gemini and Perplexity buyer questions in your category and shows if you appear.
Are free AI visibility checkers accurate?
They are a useful snapshot. AI answers vary between runs, so treat one result as a sign, not a final score, and re-check over time.
Do I need to sign up?
The GrandRanker checker needs no signup. HubSpot asks for details for the full report, and Semrush and Ahrefs push you toward an account.
What is the difference between a checker and a tracker?
A checker is one free snapshot. A tracker runs the same questions every week and shows the trend against competitors.
