The AI Visibility Directory

A verified registry of websites publishing AI Discovery Files: the 10 machine-readable files that help AI systems discover, interpret and represent a business accurately.

Every entry is fetched from the live site and scored on how many of those files it publishes, not on what the owner claims. Listings are re-checked each quarter.

AI Discovery Files

AI Discovery Files are an open, versioned community specification for publishing AI-readable website identity, usage, brand, and context information at predictable root-level paths.

The goal is to move from emerging convention to recognised implementation standard through open specifications, conformance tests, validators, public adoption research and interoperable implementations.

How AI visibility scores are calculated

A listing's score is the number of the 10 AI Discovery Files we could fetch from the site: llms.txt, llm.txt, llms.html, ai.txt, ai.json, identity.json, brand.txt, faq-ai.txt, developer-ai.txt and robots-ai.txt.

Scores map to four tiers: Platinum for all 10 files, Gold for 8 or 9, Silver for 5 to 7 and Bronze for 2 to 4. There is no manual judgement and no weighting, so two sites publishing the same files score the same.

How scoring works in detail

The free WordPress plugin

On WordPress, our free AI Discovery Files plugin generates all 10 files from your dashboard, with no coding and nothing to upload by hand. It is GPL, published on WordPress.org, with no pro tier and no feature gating.

It also logs which AI crawlers fetch your files, so you can see GPTBot, ClaudeBot, PerplexityBot and the rest arriving rather than guessing. Publish the files, submit the domain, and the listing scores itself.
