llms.txt for Squarespace
Squarespace generates robots.txt and sitemap.xml for you but offers no way to serve a custom root file. The workable route for llms.txt is an edge proxy in front of your domain.

The short answer
Squarespace manages robots.txt and sitemap.xml automatically and does not
document a setting to host an arbitrary text file at your domain root. Uploaded files live on Squarespace's
asset paths, not at yourdomain.com/llms.txt. The reliable workaround is an edge
layer you control in front of the domain.
Your options
- Edge proxy. With your DNS on Cloudflare (proxy enabled), a Worker routed on
yourdomain.com/llms.txtreturns the file astext/plainand forwards everything else to Squarespace. The Worker code is identical to the one on our Webflow guide. Check Squarespace's domain-connection requirements before enabling the proxy. - Watch for native support. If Squarespace adds a setting for AI files (their SEO panel evolves), prefer it over a proxy and delete the Worker.
What to avoid
- Linking an asset URL. A file under Squarespace's asset paths is not at the conventional root location.
- A page named llms-txt. An HTML page does not satisfy the spec, which expects plain Markdown served as text.
