What's the difference between llms.txt and robots.txt or sitemap.xml?

robots.txt tells crawlers what to visit; sitemap.xml is a flat URL list. llms.txt is curated — markdown summary with descriptions, optimised for AI engines.

Is the generated file edit-friendly?

Yes. The output is plain markdown — open it in any editor and customize before publishing.

How is this different from FAQAudit itself?

This tool generates a site summary file. FAQAudit (the full product) audits how AI engines treat your FAQ content across ChatGPT, Gemini, AI Overviews, and Perplexity.

Q: Do AI engines actually read /llms.txt files?

Adoption is early but growing. Anthropic's Claude, OpenAI's GPT-4 with browsing, and several smaller AI crawlers have started honoring the standard.

Q: Where do I put the generated llms.txt file?

Upload it to the root of your domain so it lives at https://your-site.com/llms.txt — same as robots.txt or sitemap.xml.

What is llms.txt?

A simple summary file for AI search.

llms.txt is a proposed standard for sites to publish a clean, markdown-formatted summary at /llms.txt.

Think of it like robots.txt for AI crawlers — a structured TOC of your most-citable pages, without nav/footer noise.

FAQ

Common questions about llms.txt.

Adoption is early but growing. The standard launched in late 2024 and is championed by Jeremy Howard (fast.ai). Anthropic's Claude, OpenAI's GPT-4 with browsing, and several smaller AI crawlers have started honoring it. Even if not all engines read it today, the file is cheap to publish, costs nothing to maintain, and improves your site's discoverability for the engines that do use it.

Upload it to the root of your domain so it lives at https://your-site.com/llms.txt. Same place you'd put robots.txt or sitemap.xml. Most static-site generators have a built-in way to add files at the root; CMSs like WordPress need a plugin or manual upload via FTP.
