Build or check your llms.txt
A small file, honestly
The format
An H1 with your name, a one-line summary in a blockquote, optional prose, then H2 sections of links written as - [name](url): notes. A section called Optional lists what an agent may skip.
Who reads it
Coding assistants, IDE tools and some AI agents fetch it to find docs fast. There is little evidence that ChatGPT, Gemini or Google AI Mode read it when they answer.
What it costs you
Minutes. Keep it to the pages you would hand a new colleague, update it when they move, and leave email addresses out: the file is public and scraped.

llms.txt Generator and Validator FAQ

Does llms.txt help me show up in AI answers?
There is little evidence it does today: the major answer engines have not said they read it, and server logs rarely show them fetching it. Publish it because it is cheap and useful to the agents that do read it, not as a ranking tactic.
Who does read llms.txt?
Coding assistants and developer tools that support it, some AI agents, and people who want a quick map of a site. Documentation sites benefit most.
Where does the file go?
At the root of your domain, as /llms.txt, served as plain text. Most platforms let you upload it as a static file.
Why no email or phone in the generated file?
The file is public and read by scrapers, so contact details invite spam. Link your contact page instead.
How is it different from robots.txt?
robots.txt says which crawlers may fetch which paths. llms.txt is a map of what is worth reading. One controls access; the other only points.
Measure what AI says about you
llms.txt is a small part. Rank Prompt tracks the answers, the sources they cite and the competitors they name instead of you.
