Free llms.txt Generator

llms.txt is a plain-text Markdown file you host at https://yourdomain.com/llms.txt. It gives AI assistants like ChatGPT, Claude, and Perplexity a curated list of the pages on your site that matter most — with short summaries LLMs can use when answering questions about you. Unlike robots.txt or sitemap.xml, it's written for humans and machines together, and lets you prioritize content without relying on a crawler to guess.

We fetch your homepage to pull the site name and meta description, then discover your sitemap (via robots.txt or /sitemap.xml), group the URLs into standard sections like Docs, Product, and Blog using URL path heuristics, and render the whole thing as Markdown. The output is capped at reasonable sizes so the file stays scannable by LLMs with small context windows.

Usually you'll want a quick human edit — tightening the summary, renaming sections, and adding a short description on the most important links. The generator gives you a strong starting point that saves about 80% of the manual work; the last 20% is worth doing by hand so the file reflects your brand voice.

Upload the contents to https://yourdomain.com/llms.txt — at the site root, not in a subdirectory. The file must be served as plain text (content-type text/plain or text/markdown) and must be reachable without authentication. Most static hosts (Vercel, Netlify, Cloudflare Pages) let you drop it in the public folder; for CMS sites, use whatever mechanism you use to serve robots.txt.

Yes. No sign-up, no credit card, no rate limit on the anonymous path. The heuristic generator is completely free. GeoVector's paid plans add LLM-written summaries, automatic re-generation when your sitemap changes, and monitoring that alerts you when your llms.txt drifts from your site.
