LLM Brand Visibility Checker
See whether ChatGPT, Claude, Gemini, and Perplexity mention your brand for the prompts that matter — and whether they describe you accurately.
Tip: phrase it the way a buyer would ask an AI assistant.
Public version: 1 prompt × 1 model. Sign in for multi-model panels.
The three things every brand needs to know in AI search
1. Are you mentioned? When a buyer in your category asks ChatGPT or Perplexity for a recommendation, are you in the answer? Most brands have never checked. The ones that do find out they're invisible for ~70% of the prompts where they should be a contender.
2. Are you cited? Mentions are good. Cited links back to your domain are better — they drive both buying intent and the kind of reinforcement that compounds over time as the LLMs re-train.
3. Are you accurate? This is the silent killer. LLMs confidently state wrong pricing, wrong founder names, wrong product claims. Most LLM-tracking tools count mentions and call a hallucination a positive signal. We compare the answer to your verified Brand Truth doc and flag the false claims — because a confident wrong answer to 10,000 buyers is worse than no answer at all.
Frequently asked questions
- What is LLM brand visibility?
- LLM brand visibility is your share-of-voice inside the answers Large Language Models generate. Where SEO measures whether you rank on Google, LLM visibility measures whether ChatGPT, Claude, Gemini, and Perplexity actually mention you when a buyer asks them a relevant question — and whether they describe you accurately.
- Why does this matter in 2026?
- ChatGPT alone has 700M+ weekly users. Perplexity is the default search for many B2B buyers. If a competitor is recommended in those answers and you aren't, you've lost the consideration set without ever appearing in Google. Gartner projects a 25% drop in traditional search by year-end 2026 — most of that demand is moving to LLMs.
- What does this tool actually check?
- We send your prompt to ChatGPT (GPT-5), Claude Sonnet 4.6, Gemini 2.5 Pro, and Perplexity Sonar. For each response we extract: whether your brand is mentioned, whether your domain is cited as a source, the sentiment of the mention, and which competitors were named alongside (or instead of) you.
- What's a hallucination check?
- Even when LLMs mention your brand, they often state facts incorrectly — wrong pricing, wrong founders, wrong feature claims. The MarqOps hallucination detector compares LLM-stated claims against your verified Brand Truth document and flags discrepancies by severity. Most LLM-tracking tools (Profound, Otterly, Peec) count mentions but don't check accuracy. We do.
- Is the public version free?
- Yes — run one prompt through one model here, no signup. For multi-prompt panels (up to 15 prompts × 4 models per run), scheduled rechecks, hallucination alerts, and competitor share-of-voice tracking, sign up for MarqOps.
- How do I improve my LLM visibility?
- Three levers, in order of impact: (1) ship structured data so LLMs can parse your entities — use our free Schema Generator, (2) restructure content so it's citation-ready — use our GEO Score, (3) earn third-party mentions on Reddit, G2, Trustpilot and trade publications, since LLMs heavily weight those sources.
