PRISM Framework · Layer 1: Platform
This tool checks the Platform layer only—how AI engines access your site. It does not check whether AI understands who you are, trusts what you say, or recommends you to anyone. Those are covered in Layers 2–5 of the PRISM framework, and they require a closer look at your specific situation.
Common questions
Check your robots.txt file for OAI-SearchBot and ChatGPT-User directives. If either is listed under Disallow, ChatGPT can't find or read your pages. GPTBot is different: it collects training data, and blocking it doesn't stop ChatGPT citing you. The PRISM Platform Checker audits this automatically—paste your URL and get an instant result.
GPTBot is OpenAI's training crawler. It collects web content that may be used to train future OpenAI models. It doesn't power ChatGPT Search: that's OAI-SearchBot, with ChatGPT-User fetching pages live during conversations. Blocking GPTBot opts you out of training without affecting whether ChatGPT can cite you. Blocking OAI-SearchBot is what removes you from ChatGPT's answers.
Most accidental AI crawler blocks happened in 2023–2024 when site owners added broad bot-blocking rules to prevent AI training on their content. Those same rules now block the retrieval crawlers that power AI search. It's one of the most common—and most fixable—reasons small businesses are invisible to ChatGPT and Perplexity.
No. Major AI crawlers—including GPTBot, ClaudeBot, and PerplexityBot—do not execute JavaScript. If your site relies on JavaScript to render its content, AI crawlers retrieve a near-empty page. Your site can look polished to a human visitor while being effectively invisible to every AI search engine.
llms.txt is a proposed plain-text file at your domain root that points AI tools to your most useful pages. Google says Search doesn't use it, and a 2026 Ahrefs study found 97% of published files received zero requests. We recommend adding one because it's quick and the convention is still forming, but it isn't proven to affect rankings or citations yet. It is not a substitute for the foundational platform checks: bot access, crawlability, and HTML-first rendering.
PRISM is a sequential five-layer framework for making a founder-led business visible to AI search engines—ChatGPT, Perplexity, Claude, and Google AI Mode. The five layers are Platform, Recognition, Intelligence, Signal, and Momentum. Each layer enables the next. You cannot skip ahead.
