About Thundercrawl
Thundercrawl is a web tool that converts a website into LLMs.txt files, a plain-text format intended to make site content readable by large language models. The service positions this as a form of AI SEO, aiming to improve a site's visibility to AI tools and drive referral traffic from Grok.
Users enter the URL of the site they want to convert and choose a processing mode: a full site crawl or a single page. A maximum page setting and advanced options are also available. Generated files can be revisited through a "My Generations" area after logging in.
A free sample tier covers up to 5 pages, 10 blog posts and 10 products, with premium plans offered for larger sites. The site also publishes guides on what LLMs.txt is and how to create these files, aimed at site owners and marketers interested in AI discovery.
