Questions and answers

What is an llms.txt file?
llms.txt is a proposed file at a site's root that points AI assistants to its key docs, using one H1, a one-line summary blockquote and Markdown link sections. This generator assembles the file from your project name, summary and link sections, and validates an existing one for missing parts and non-absolute URLs.
How do I build one here?
Enter your project name, a one-line summary, optional details, then add link sections with titles and absolute URLs. The file is assembled live and you can copy or download it.
Can it validate an existing llms.txt?
Yes. Switch to Validate mode and paste a file. It reports structural issues such as a missing H1, no summary blockquote, malformed links, or non-absolute URLs.
Where should llms.txt live?
At the root of your domain, served as /llms.txt. Link to the docs that matter most; an optional section can list lower-priority pages to keep the core list focused.
Is my content uploaded?
No. Generation and validation run entirely in your browser. Nothing you paste leaves the page.
