Follows the llms.txt Standard
Built to the emerging llms.txt spec with clear sections, page summaries, and links AI crawlers can parse.
An llm.txt generator creates the llms.txt file that guides AI models and chatbots as they read your site. The file lists your key pages and short descriptions in plain markdown, giving assistants a curated map of your most useful content. This free tool builds that file from your URLs, so large language models can find, cite, and summarize your pages accurately instead of guessing at your structure.
What the llms.txt file contains
The generator produces a plain text file, formatted in markdown, that lives at the root of your domain as llms.txt. It opens with your site name and a short summary of what you offer, then lists sections of important links with a brief note about each one. You might group documentation, product pages, and articles under their own headings, each pointing an AI model to the canonical URL. Unlike a sitemap, which lists everything for crawlers, this file is a curated shortlist meant for language models. The output is ready to save and upload, giving assistants a concise, human written guide to the content you want them to use.
How to publish your llms.txt file
Save the output as llms.txt and upload it to the root of your domain, so it is reachable at yoursite.com/llms.txt, the same way robots.txt is served. Keep the file in plain text and check that every link resolves to a live, canonical page. If you maintain detailed docs, you can also add a fuller llms-full.txt with expanded content. Update the file whenever you publish major new pages or restructure your site, since a stale list points models to the wrong places. Because the format is young, treat it as a helpful signal rather than a guarantee, and pair it with clean on-page content that AI systems can read directly.
Best practices for AI crawler files
Keep the list short and high value, pointing models to the pages you most want them to cite rather than every URL you own. Write clear, honest descriptions, since the note beside each link helps an assistant decide what the page covers. Use stable, canonical URLs so the file stays accurate as your site evolves. Organize links under logical headings like docs, guides, and products, which makes the structure easy for a model to parse. Do not treat llms.txt as a replacement for robots.txt or an XML sitemap, since each serves a different purpose. Revisit it on a regular schedule so the guidance you give AI tools reflects your current best content.
