# AISO

> AISO is a free AI-search visibility scanner that grades any URL from 0 to 100 across crawler access, content structure, citation density, schema quality, freshness, entity clarity, off-site authority, and live citation visibility.

AISO follows current search-engine fundamentals first: crawlable pages, truthful structured data, canonical URLs, and visible text. The product also ships optional AI-discovery files such as llms.txt so teams can expose their docs and integration entrypoints to developer tools and emerging AI crawlers.
