LLM visibility checker: see which models name your brand
An LLM visibility checker asks each model the same buyer questions and shows you the column where they disagree.
LLM visibility is narrower than "AI visibility" and wider than a single check button. It still is not a platform. You do not get seats, a schedule, or a history that lives on our servers. You get this run, in this browser.
What this check is
- One run you start. There is no scheduled run.
- No SeenByLLMs account, no shared seats, no data that follows you to another machine.
- You bring an OpenRouter key. Model calls are billed by OpenRouter, on top of $0, $12/mo, or $49 once.
- API answers, not the ChatGPT website and not Google AI Overviews.
- It reports what the models said this time. It does not promise a higher rank.
What to compare across models
- Named on every model: the shortlist already includes you. Look at rank, not just presence.
- Named on one model: that model has you; the others do not. Different training data, or different search results.
- Named on none: the question's shortlist is other brands. Read who, and which pages were cited.
The default picker starts with models an ordinary OpenRouter account can call, including a free model, DeepSeek, and Qwen, with GPT, Claude, Gemini, and Perplexity Sonar available on the same list. A 20-question run on five models is about $0.30 in model calls. The published case studies used one free model and cost about $0.08.
Questions
What is an LLM visibility checker?
It runs your buyer questions through large language models and records whether each model names your brand. SeenByLLMs is that checker: in the browser, on your OpenRouter key, with no account.
How is this different from the AI visibility checker?
Same product. "LLM visibility" is the narrower name for the same run: model by model, named or not named. Start at the AI visibility checker if you want the product overview.
