This connects Claude to AI Visibility Checker's free GEO audit API to check whether ChatGPT, Perplexity, and Google AI recommend a brand when users ask category questions. You can query visibility scores across 15 markets and languages, see which competitors AI names instead, and pull structured site audit data showing what blocks AI citation. Useful when you're optimizing for generative engine results and want to programmatically test brand mentions without manually prompting multiple LLMs. The underlying service uses Llama 3.3 as a proxy for how AI assistants understand brand authority, then surfaces concrete fixes to improve citability in AI responses.
