An llms.txt file is a plain markdown file at the root of a site, /llms.txt,
that gives an AI assistant a short description of what the site is and which
pages matter, in one fetch. It has been a proposal since September 2024, not
a standard, and no search engine ranks a page for having one.
Birta publishes its own, and points an agent at it directly: our landing page tells any connected tool to read it and connect itself, rather than making a person click through setup screens.
For a real one shown line by line, what the data says about whether it works, and where it stops, see what is an llms.txt file, a real one explained line by line.
