AI Visibility Tracking Tool
Ask ChatGPT and Google AI Overviews the questions your buyers ask. See whether they name your brand, what they say, and which sites they cite instead.
What an AI visibility check can and cannot tell you
AI assistants answer from two places: what the model learned in training, and pages it retrieves live from a search index. A check like this one samples the answer. It shows you what a buyer could see today, and whether the engine connects your brand to your site.
It cannot show you why. The causes sit upstream: whether AI crawlers such as OAI-SearchBot, PerplexityBot and Claude-SearchBot are allowed and can actually reach your pages, whether your key facts are in the HTML before JavaScript runs, and whether the pages that engines do cite in your category mention you. Start with the guides for the order of work, or the playbooks for checks you can run this week.

Questions about the checker
What is an AI visibility tracking tool?+
It is a tool that asks AI assistants such as ChatGPT, Google AI Overviews, Perplexity, Gemini and Claude the questions your buyers ask, and records what comes back: whether you are mentioned, how you are described, whether the facts are right, and whether your site is cited. Tracking means doing that repeatedly with the same prompts so you can see change over time.
What does this free check measure?+
It runs 99Visibility's free check: up to three buyer questions (yours, or written from your homepage without your brand name), asked to ChatGPT with web search and to Google AI Overviews. For each answer it records whether you are named, the tone, and the sources cited, and scores the result 0 to 100 with 99Visibility's scoring. It is a snapshot, so answers can differ from one run to the next.
What can it not tell me?+
Three questions cannot tell you how often you appear across everything your buyers ask, whether AI crawlers can reach your pages, or which specific facts are wrong. Those need a prompt set, an access check and a fact review. The library on this site explains each one, and 99Visibility runs them continuously.
Is it free?+
Yes. The check is free and needs no account or card. An email address opens the full report with every answer. Each visitor can run 3 checks an hour.
Who runs this site?+
Torch99, the company behind 99Visibility. The library is AI-assisted and written from a verified evidence base; the editorial policy explains how. The site is also a public experiment in how AI engines discover and cite pages.
