# Adding llms.txt to a Notion site

> Notion's native publishing can't serve a root text file, but an edge proxy or a Notion-site platform gets a working llms.txt live. Your options.

Notion's built-in site publishing is locked down — it serves your pages, not custom files — so an [llms.txt](/guide/what-is-llms-txt) needs help from the layer around it.

## Option 1 — an edge proxy on your custom domain

If you serve your Notion site through Cloudflare (or a similar CDN) on a custom domain, serve `/llms.txt` from a small edge worker that returns your text as `Content-Type: text/plain`. This is the most reliable route and keeps the canonical root URL.

## Option 2 — a Notion-site platform that supports it

Tools that publish Notion content as a site (Super, Potion, Notiondesk and others) add capabilities Notion lacks — custom code, redirects, and in some cases an auto-generated `llms.txt` built from your pages. If you use one, check its docs or AEO settings.

## Native Notion alone?

On a plain notion.site with no proxy or builder, there's no supported way to serve a plain-text root file — so use one of the options above.

## Validate

Paste your domain into the [validator](/) to confirm `/llms.txt` is reachable as plain text and every link resolves.
