Is There a Free Way to Check If My Brand Is Mentioned in ChatGPT or Perplexity Answers?

Yes. You can get a real read on whether ChatGPT or Perplexity name your brand in under ten minutes, for zero dollars, without installing anything. What you cannot get for free is confidence over time. Free methods produce a snapshot, and the engines re-rank their answers continuously, returning different brand lists on repeat runs of the same prompt. So treat everything below as a diagnosis, not a dashboard.

It is worth the ten minutes because 71 percent of B2B buyers now rely on AI chatbots for software research (G2, 2026). If the answer to your category question names three competitors and not you, that answer is the shortlist, and you were not on it.

Here are the free checks worth your time, ranked by how much signal each one actually gives you, and where each one breaks.

1. Ask the engines yourself, logged out

Open ChatGPT, Claude, Gemini, and Perplexity. Type the exact question your buyers type, something like "best [category] tool for [use case]," and write down every company named, in order.

The trap is doing it from your own logged-in account. Memory, custom instructions, and months of chat history about your own company bias ChatGPT toward naming you, which produces a false positive that feels like great news. Use a temporary chat with memory off, or a logged-out incognito window. Then run the same prompt three or four times. A single answer means almost nothing. The frequency across runs is the number.

Highest-signal free check available, and it costs nothing but the discipline to log out first.

2. Run a free AI visibility scan

Paste your domain into a vendor scan and get back whether the engines recommend you and who they name instead. Ours is at claritysearch.ai/tools/ai-visibility: free, no account needed, and a short form unlocks the full result. We wrote a walkthrough of how to run one on your own site.

Be honest about the limitation shared by every scan in this category, including ours. It takes a URL, not your buyers' questions, so the prompts behind the result are inferred from your site rather than lifted from your sales calls. And it is one moment in time. Before you trust any scan's "you are invisible" verdict, check which engines it actually asked, because a result built on ChatGPT alone is not a read on Perplexity.

The fastest way to see your absence in writing. Use it as the diagnosis, not the tracking.

3. Segment AI referrals in your analytics

Build a custom channel grouping that matches referrers like chatgpt.com, chat.openai.com, perplexity.ai, claude.ai, and gemini.google.com. Free in the analytics you already run, and it answers a different question than the first two checks: not whether AI names you, but whether the naming sends humans.

This undercounts, badly. Mobile apps strip referrers, agentic browsers frequently send none at all, and plenty of buyers see you in an AI answer and then retype your name in the URL bar three days later, which lands as direct traffic. We wrote about why so much AI traffic looks like direct. Read your referral number as a floor, never a total.

Essential, incomplete, and free. Set it up today and stop treating the number as final.

4. Grep your server logs for AI crawler user agents

Search your access logs or CDN logs for GPTBot, PerplexityBot, ClaudeBot, and friends.

Crawling is not citation. A crawler hitting your pricing page proves the door is open, nothing more. It is worth doing anyway, because it catches the opposite problem: a robots rule quietly blocking the bots that would have quoted you.

Diagnostic plumbing check, not a mention check.

5. Read the sources the engines cite

In Perplexity, and in ChatGPT when it browses, open the cited links. Note which third-party pages keep recurring.

Reddit threads, review directories, and category roundups do a disproportionate amount of the work in shortlist answers. If the same three URLs sit behind every answer that names your competitor and not you, that is your off-site target list, and it is free to read. This is the check most founders skip and the one that changes what you do on Monday.

The most actionable free check, because it tells you where the answer is being assembled.

6. A permanent free tier, for a repeatable baseline

Manual checks decay because nobody keeps doing them. Our Free plan exists for that reason: free forever, no credit card, tracking 3 monitoring questions on ChatGPT with one on-demand visibility check per rolling week. Narrow on purpose. It gives you a baseline you can return to instead of a memory of what an answer said last month.

Worth setting up if you plan to check more than once.

What no free method can tell you

Free gets you the gap. It does not get you daily monitoring across all four engines with your questions rotating through the week, asked the way a real buyer in your market and location would ask them, or a competitor share-of-voice trend, or the stored answers and cited sources kept as receipts. And it will not settle the argument that actually gets settled in a board meeting: whether an AI answer produced a lead and a dollar.

Bosten Shoes went from unmentioned to the number-one recommended leather shoe brand in El Salvador, and saw its first ChatGPT-attributed sale in under 30 days. A logged-out manual test would have shown the first half of that sentence. Only referral data tied to closed revenue shows the second half. Everyone shows you mentions. The mention is not the point.

Run the logged-out test and the free scan this week. Write down the competitor names you see, because that list is the brief. Whether you pay to make the check continuous is a later decision, and the price is public when you get there.

This is one snapshot. Clark runs it continuously.
