llms.txt Validator

llms.txt is an emerging convention (analogous to robots.txt) that gives ChatGPT, Claude, Perplexity and other AI assistants a curated overview of your site so they can cite you more accurately. This tool fetches and validates yours against the proposed convention at llmstxt.org.

Make AI assistants cite you accurately

The Nova Insight Website Audit checks llms.txt presence, AI crawler access, schema markup, server-side rendering, and 200+ other signals that determine whether ChatGPT and Claude will recommend your business in answers.
