I built a free tool that generates an llms.txt file from a website URL.
You just enter the main website URL, and it tries to detect the sitemap, collect important pages, extract titles and descriptions, and generate a structured llms.txt file that you can preview and download.
also I think the main question people will have is why do I need a llm.txt, your answer "It can give AI systems a cleaner, more focused view of your site, which may help them interpret, summarize, and reference your content more accurately." doesn't sell it. maybe if you had example of what ai systems are currently using it ?
