What an LLM visibility check is
An LLM visibility checker measures how you show up inside large language model answers — not inside Google’s ten blue links. This page is the same free public report as the AI Visibility Checker: brand, domain, industry, optional competitors, twelve buyer-style prompts, and a fan-out to ChatGPT, Claude, Gemini, and Perplexity via model APIs. You get one Answer-Engine Visibility score, a letter grade, and a per-engine breakdown of mentions and typical position.
People search “LLM visibility” when they want the multi-model picture, not a single-vendor gadget. That is this engine. We do not open the consumer chat apps. We query the APIs, judge each answer for mention, position, citation, and sentiment, and mark soft-fail cells when one vendor is down. One flaky LLM does not erase the rest of the run.
How the four-model run works
You supply the brand details; we do not infer them from a homepage. That is the difference from the domain-only AI Visibility Score, which uses eight inferred prompts. This checker is for teams that already know the brand and the rivals they want scored across LLMs. On-screen results stay free. Email unlocks the PDF of raw model answers.
If you only need ChatGPT — base knowledge versus search — use the ChatGPT Visibility Checker. If you want the same LLM prompt set watched over time, sign in and continue to AI Brand Monitoring. Scores move between runs; treat each as a snapshot of what those models said today. The brand-name keyword landing is AI Brand Visibility Checker; this page stays on the multi-model wording.
