# The Agent Visibility Directory

A catalogued index of tools that measure how AI systems describe a brand.

An index of tools that measure how AI answer engines (ChatGPT, Gemini, Perplexity,
Google AI Overviews, Claude, Copilot and others) describe a brand. The category noun
used here is **agent visibility**; the same market is sold elsewhere as AI SEO, AEO
and GEO.

## What this data is

Every field was read from the vendor's own website on the date in `verified_on`, and
`source` holds the exact URL it came from. Where a vendor publishes no price or no
engine list, the field is null or empty rather than estimated. There is no paid
placement and there are no affiliate links, so the ordering carries no commercial
weight.
