Check whether ChatGPT mentions your brand.
Type a question your customers would ask. We put it to ChatGPT, Claude, Gemini and Perplexity with live web search, right now, and show you every answer that comes back. Including the ones that never mention you.
How to read what came back.
- One question, four engines
- The same prompt went to all four at once with live web search on. The answers are the ones a customer would have got today, not a summary of what the models remember from training.
- Every brand that got named
- Count who appears. The names that keep turning up are winning this question.
- Where you sit in the answer
- Mentioned ninth in a list of nine is not the same result as being the first thing an engine says, and the two get reported identically by anything that only checks whether your name appears.
- Which sources they leaned on
- The URLs an engine cited are the pages it trusted enough to lean on.
Three more on reading answer engines are in the guides: which sources they cite, how reliable a run is, and what to ask a vendor before you pay one.
Frequently asked questions
How do I check if my brand appears in ChatGPT?
Type a question a customer would ask, add your brand name and a work email, and run the check. Prism puts the same question to ChatGPT, Claude, Gemini and Perplexity with live web search on and shows every answer in full, each marked mentioned, not mentioned or no answer. It takes 30 to 60 seconds and needs no account.
Is this AI brand checker free?
Yes. Three checks a day, no account and no card. Each check is four live answer-engine calls, paid for by Prism, and the daily cap covers that.
Can I see which sources ChatGPT used when it mentioned a brand?
Yes, where the engine returned them. Each answer lists the URLs the engine cited while replying. Those are the pages it trusted enough to lean on, and they are where a brand that wants to be named next time needs to appear.
Why do the answers change between checks?
Because the engines are not deterministic, and three of the four search the web live, so the sources they find shift from day to day. One check is a snapshot. The AI Visibility suite runs the same prompts on a schedule and reports the mention rate across runs.
How do I track brand mentions in ChatGPT and Perplexity over time?
Create a free account, write up to ten prompts on Starter ($19 a month), and they run on the schedule you set across all four engines. Every answer is kept word for word, so share of voice, answer position, sentiment and citations are read from real text. New accounts get 100 credits, enough for one full scan before paying anything.
One question is a snapshot. Tracking is the job.
Ask the same engine the same thing tomorrow and the answer will be worded differently, sometimes with different brands in it. The AI Visibility suite runs the same prompts on a schedule and keeps the history, so the number you quote is a rate across many runs.
- Runs on your schedule
- The same prompts go to the same four engines on the cadence you set.
- Every answer kept
- Word for word, so any number on any report traces back to the sentence it came from.
- A rate, not a day
- Share of voice measured across runs, against every brand named beside you.
The engines will answer differently next week.
Create an account and the same prompt runs on your schedule, with every answer kept, so you can go back and see the week the engines changed their minds. New accounts get 100 credits, which covers one full scan across all four before you decide anything.
