What does the AI visibility score measure?

It measures how many AI crawlers and search engines can reach your site, plus whether you publish an llms.txt file.

Is the AI visibility check free?

Yes. You can enter your URL and get a full report in seconds with no account or credit card required.

llms.txt is a file at /llms.txt that gives AI systems a clean, direct summary of your website content.

Which AI crawlers are checked?

The tool checks 13 crawlers across search engines, AI training crawlers, and AI answer engines, including Googlebot, GPTBot, ClaudeBot, and PerplexityBot.

Can I use an AI assistant instead of the form?

Yes. The site provides a public API and publishes the request format in its llms.txt so AI assistants can read and use it.
