# LLMS.txt Checker

> Paste the URL of a site or your llms.txt text and get an instant validation report against the llmstxt.org spec. Free, no signup, checking runs entirely in your browser.

## What it does

- Fetches a site's /llms.txt (or takes pasted text) and runs 10 checks against the llmstxt.org spec.
- Reports each check as pass, warning or failure, with a plain-English explanation of what is wrong.
- Computes an overall score so you can see progress as you fix issues.
- Flags common problems: missing sections, bad Markdown links, wrong content-type, unreachable URLs.
- "Copy as Markdown" exports the full report for pasting into a chat, docs or a pull request.

## Who it is for

Developers and site owners who publish an llms.txt for AI crawlers and want to know whether the file actually follows the spec.

## Pricing

Free. No account, no signup. Checking runs locally in the browser; nothing you paste is uploaded to a server.
