# What is llms.txt and do I need one?

**Direct answer:** llms.txt is a plain-text file at the root of your site that summarizes what your organization does and lists your most important URLs in an AI-readable format. It is a proposed convention rather than a required standard, it is inexpensive to publish, and it helps AI systems and agents orient quickly — but it does not replace crawlable pages or structured data.

## What to put in it

A one-paragraph description of the company, then grouped links: core pages, products or plans, guides and articles, and policies. Keep the descriptions factual and short. Atomik Digital publishes one at /llms.txt.

## What it will not do

It will not make an uncrawlable site crawlable, and no engine currently guarantees it reads the file. Treat it as a cheap orientation layer on top of a healthy site, not as a strategy.
