How to use it

Check a file in three steps.

  1. 01

    Paste your file

    Copy the contents of your llms.txt into the box. Nothing is uploaded; the check runs in your browser.

  2. 02

    Read the findings

    Errors break what the format requires. Warnings are worth fixing but will not stop the file being read.

  3. 03

    Fix and re-check

    Edit the text in the box and the list updates as you type. Copy the fixed file back to your site.
