llms.txt Generator — Guide AI Assistants Through Your Site

Build a valid llms.txt: a curated, Markdown map of your site written for a model with a limited context window.

llms.txt is a Markdown file served at the root of your domain that gives AI assistants a curated map of your site: an H1 with the project name, a blockquote summary, and H2-grouped lists of links with descriptions. This generator builds one and validates it against the spec — absolute URLs, descriptions on every link, and an Optional section that a model may skip when context is tight.

Frequently asked questions

Do AI models actually read llms.txt?

Some tools that build retrieval over documentation do. No major model provider has committed to reading it as part of normal crawling, and it is a proposal rather than a standard. It costs almost nothing to publish and it is genuinely useful to anyone indexing your docs — publish it on that basis rather than expecting a ranking effect.

What is the difference between llms.txt and llms-full.txt?

llms.txt is an index: links with descriptions, so a model can choose what to fetch. llms-full.txt is the whole corpus inlined into one file, so an assistant can ingest everything in a single request. Generate the second one in your build — a hand-maintained copy of your documentation is stale immediately.

Is this the same as robots.txt?

No, and they are complements. robots.txt says what a crawler may not take; llms.txt says what is worth reading and how it fits together. One is a restriction, the other is a recommendation.
