Free llms.txt generator
Paste a URL. Get an llms.txt you can publish today.
llms.txt is a small file at the root of your site that tells language models what the site is and which pages matter. It is to AI crawlers roughly what robots.txt is to search crawlers — a short, deliberate statement rather than something inferred from your markup.
It is still an emerging convention rather than a standard anyone is obliged to honour. The cost of having one is a few minutes; the cost of not having one is that models describe you from whatever they happened to scrape.
What this free version does not do
This reads one page and builds the file from its title, description and navigation. The version inside Xeostack reads your whole site and writes the descriptions properly, rather than lifting them from link text — this one is a good starting file, not a finished one.
Other free tools
These are one page each. Xeostack does the same work across your whole site, continuously.
