How they work
Live engine output, not a cached index.
Free tools are usually a lead form with a progress bar. These are not, so it is worth saying exactly what happens when you press the button.
- 01
We generate the prompts
Your category and domain produce the questions buyers actually ask, not keyword variants. The prompt set is shown to you before anything runs.
- 02
We query the engines directly
Every check hits ChatGPT, Google AI Overviews, Perplexity and Gemini in the moment you ask. Nothing is served from a stored crawl.
- 03
We show the receipts
Each number links to the answer text and the sources behind it. If a claim cannot be traced to an answer, it does not appear in the report.
- No cardNothing here asks for payment details.
- No account to run themOnly the full visibility report emails you a copy, which needs an address.
- Your data stays yoursWe do not sell prompt sets or resell your report as benchmark data.
Related questions
People also ask
The questions engines cluster with this page. Each one is answered here rather than on a separate landing page.
Yes. The AI Visibility Checker is free and needs one domain. It runs your category's buying questions across ChatGPT, Google AI Overviews, Perplexity and Gemini, then reports how often each names you, which sources it quoted instead, and what to fix first. No card is required and the report takes about ten minutes.
Run the checker →FAQ
Questions about the free tools.
Do I need an account to use these?
The free tools run with no account at all. The full AI visibility report emails you a copy, so that one needs an address. Nothing asks for a card.
How often can I run them?
The LLMs.txt Generator runs entirely in your browser and is unlimited. The AI Visibility Checker is limited to a few runs a day per domain, because each run queries four engines live and that cost is real.
Is the data the same as the paid product?
The measurement is identical, the coverage is not. The free check runs one prompt set once. Prefer keeps running your full prompt library, holds history so you can see trends and regressions, tracks competitors on every run, and routes fixes to owners.
Can I use the output in a client report?
Yes. Agencies do this constantly and it is fine. The export includes the prompt set and the source list so the client can check your work. If you want white labelled reports and multiple client workspaces, that is the agency plan.
Why is my visibility zero?
Usually one of three things: the engines cannot crawl you, your pages answer nothing directly, or your category is dominated by review sites and roundups that quote each other. The AI Visibility Checker tells you which.
Do these work for languages other than English?
The AI Visibility Checker supports multiple languages and reports per market. The LLMs.txt Generator is language agnostic. The tools still in build will note their language support when they ship.
