Engine Matrix.
The technical reference specification for all 11 frontier AI search crawlers. Distinguish live citation bots from offline training scrapers with verified user-agents, IP ranges, and RFC 9309 rules.
Which AI Crawlers Ingest Web Content for Live Conversational Citations?
There are two distinct categories of AI web bots: Citation Crawlers and Model Training Scrapers. Citation crawlers (such as OAI-SearchBot for ChatGPT Search, PerplexityBot for Perplexity Sonar, Claude-SearchBot for Claude Web, and Applebot-Extended for Apple Intelligence) query websites in real time to generate verifiable footnote links in synthetic answers. Blocking these crawlers in your robots.txt results in total exclusion from conversational search engines.
Deterministic readiness across 5 generative search networks.
Legacy SEO tools only evaluate static Google indexes. AI Search Fixer validates your domain against the live, distinct citation algorithms of OpenAI, Perplexity, Google, Anthropic, and Microsoft.
