# llms.txt checker

> Fetches your /llms.txt and reports whether it exists and how it is structured. Ships beside our own published finding that the evidence for llms.txt is weak.

- Canonical page: https://lantad.co/tools/llms-txt
- This file: https://lantad.co/tools/llms-txt.md

## Key facts

- **What it reports:** Whether a file is served, its title, its section and link counts, its size, and a preview.
- **The honest position:** No measurement currently shows llms.txt changes what AI engines do, and one large study points the other way. We ship the checker and publish that finding anyway.
