/llms.txt File Validator

Audit your domain's AI context manifest against official standards. Ensure ChatGPT Search, Perplexity, and Claude ingest your technical documentation accurately.

What is /llms.txt?

Similar to how /robots.txt governs traditional search engine crawlers, /llms.txt provides a standardized, curated index of markdown files specifically structured for Large Language Models (LLMs) to ingest into context windows when answering user queries.

Why Generative Engine Optimization (GEO) Matters

Over 30% of technical queries are now answered directly within AI search engines (Perplexity, ChatGPT, Claude) without ever clicking through to a classic Google SERP. Having an authoritative, high-density /llms.txt ensures AI models quote your documentation directly rather than hallucinating outdated API patterns.
