# llms.txt Generator

> An llms.txt generator builds the markdown file at your site root that tells large language models which pages best answer questions about you. It is a proposal rather than a ratified standard, but it costs one file and makes your key pages easy for a model to find and cite.

## Questions

### Does llms.txt actually do anything yet?

It is a proposal, not a standard, and no major AI engine has committed to reading it. It costs ten minutes and is a plain-language summary of your site, so the downside is negligible and the upside is real if adoption comes.

### How is it different from robots.txt?

robots.txt says what crawlers may not fetch. llms.txt says what a model should read first and how to describe you. One restricts, the other guides.

### What should go in it?

A one-line description, then links to the pages that answer the questions people ask about your product - pricing, docs, comparisons. Not your whole sitemap.

### Should I also serve markdown versions of pages?

The full proposal suggests a .md twin of each page. That is more work and more useful - it gives the model clean text with no navigation chrome.

### Do AI engines actually read llms.txt?

No major engine has confirmed it as a ranking or retrieval input. The pages it points at are read regardless, so the file is cheap insurance rather than a lever.

### What is llms-full.txt?

An optional companion holding the full text of your key pages in one file, so a model can ingest everything without following links. Worth adding if your site is small.

### How does this compare with an XML sitemap?

A sitemap is exhaustive and machine-formatted for crawl scheduling. llms.txt is curated and human-readable - a shortlist of what matters with a sentence explaining each entry.

### Should I include my blog posts?

Only the ones that answer real questions about your product or field. A dump of every post defeats the purpose, which is curation.
