What is LLM Scan?
LLM Scan is an AI visibility tool made by Gorilli. It scans a website in about eight seconds and scores, out of 100, how well ChatGPT, Claude, Perplexity and other AI crawlers can read it, with a copy-paste fix for every issue. It also tracks how AI assistants mention and cite your brand.

The problem
Your best pages can be invisible to AI, and nothing in your analytics will tell you.
A robots.txt rule that blocks AI crawlers, content that only exists after JavaScript runs, a missing llms.txt or no structured data: none of these show up as an error in your usual tools. AI assistants just answer without you, or cite a competitor instead.

Questions
Is the scan really free?
Yes. The technical scan is free and needs no signup. You only create an account when you want to save projects or track AI visibility over time.
Which AI platforms does LLM Scan cover?
The technical scan checks whether AI crawlers and agents in general can read your site. Visibility tracking monitors answers from ChatGPT, Claude, Gemini and Perplexity.
Do I need a developer to apply the fixes?
Many fixes, such as robots.txt rules or an llms.txt file, are copy-paste. Markup and structured data changes are explained so a developer can apply them quickly.
Does this replace SEO?
No. It covers what classic SEO tools miss: whether AI systems can read your content and whether they mention and cite you in their answers.
