Do These LLMs Know This Website?
LLM "knowledge" is not binary. Some answers come from training data, others from retrieval/browsing, and results vary by prompt, language, and time. Our checks measure whether the model can correctly identify and describe the site for relevant prompts.

- !List in public LLM indexes (e.g., Huggingface database, Poe Profiles)Direct Discoverability: When a developer or company is looking for a specific type of model or dataset to use in their own AI application, they go directly to these hubs. Being listed there ensures your model is a part of their search results. Authority and Trust: These platforms serve as a form of social proof within the AI community. The number o…
- !LLM-crawlable llms.txtThe llms.txt file is an important tool for LLM visibility because it acts as a curated, high-priority roadmap for AI crawlers. While a robots.txt file tells crawlers what they can and cannot access, and a sitemap.xml file provides a comprehensive list of all your pages, llms.txt tells an AI exactly which content is the most important, authoritative…
- !Paywall wall detectionPaywalls are a significant factor for LLM visibility, but their impact is complex and evolving. Generally, content behind a strict, un-crawled paywall is invisible to LLMs and their indexing systems. However, many publishers use a more flexible approach, and the AI landscape itself is adapting to this challenge. Here's a breakdown of the key facto…

Does ChatGPT/Gemini/Perplexity know Identity Verification?
Sometimes, but not consistently: models may rely on training data, web retrieval, or both, and results vary by query and time. This report measures observable visibility and correctness signals rather than assuming permanent "knowledge." Our 4 LLM visibility checks confirm whether major platforms can correctly recognize and describe Identity Verification for relevant queries.
How often is this report updated?
