Common questions
- What is an llms.txt file?
- A short text file at the root of your store that tells AI assistants which pages of your shop are worth reading first. It sits next to robots.txt and complements your sitemap.
- Is the generator free?
- Yes. Generating and checking run entirely in your browser: no account, no upload, and nothing you enter leaves the page.
- Does llms.txt replace my sitemap?
- No. Your sitemap lists every URL for search engines. llms.txt is a short curated list of the handful of pages you want an assistant to read first.
- Where does the file go?
- Save it as llms.txt in the root of your store, next to robots.txt, so it answers at your domain followed by slash llms.txt. The app writes that file for you and checks it daily.
