Checker
How readable is a site to AI agents?
The checker reads a site's /llms.txt and the pages it lists, the way an
agent would, and scores it from 0 to 100.

Sites that publish an llms.txt
Scores are live and cached for up to a day. Listed as examples only.
How the score works
Five checks, 100 points. The same code runs here, in the badge and in the CLI. Only the first 10 links in an llms.txt are checked, so big files are scored on a sample.
| Check | Points |
|---|---|
| /llms.txt exists, valid H1 title, ≥1 section | 20 |
| Summary blockquote under the title | 15 |
| Markdown copies of listed pages (the link is markdown, or the page has a markdown version) | 25, proportional |
| Listed pages show text without JavaScript | 20, proportional |
| Links in llms.txt resolve (2xx) | 20, proportional |
