llms.txt Generator
Fill in a few fields and get a working llms.txt, generated live in your browser. Nothing is uploaded. Check it afterwards with the validator.

Enter a site name to start
Upload the file to your site root so it is reachable at yourdomain.com/llms.txt.
Validate it afterwards →Why a site name alone is not enough
The most common mistake is a file with a title and a few links. That gives an AI system almost nothing — after reading it, the system still doesn't know what the site does, who it serves, or how it differs from similar sites.
The summary line is the most important sentence in the file. It should answer what this is, who it's for and what makes it credible — not read like a mission statement.
How many links: ten to twenty
More is not better. Dumping the whole sitemap in removes the prioritisation. Pick the pages that actually represent the business: services, pricing, the few pieces of content that matter most.
Every link needs a one-line note. The system reads that line, not the URL.
What this tool does not do
- It doesn't write your content. Everything comes from the fields you fill; the tool only assembles the format.
- It doesn't scan your site. Generation and validation are two steps — use the checker for the second.
- It doesn't guarantee anything gets read. llms.txt is a proposal, not a standard, and no vendor has committed to reading it.
- It uploads nothing. Everything runs in the browser; close the page and the data is gone.
What to do after generating
Upload to the site root, then confirm /llms.txt returns text/plain and not HTML. Frameworks with catch-all routes hand this path to the front-end and return a 200 page — it looks like success and isn't.
Then run it through the checker to see whether all six checks pass. Free, no signup.
