A plain-text file at /llms.txt that summarises a website for AI assistants: who you are, what you offer and which pages matter.
Also called: LLMs.txt file
llms.txt is a proposed convention, similar in spirit to robots.txt. It gives language models a short, clean overview in Markdown, with links to the most important pages.
It does not replace good content and is not an official ranking factor, but it costs little to add.
Why llms.txt matters in Switzerland
For Swiss companies it is a simple place to state facts AI tools often confuse: languages served, regions, prices in CHF and the legal entity.
Our tip
Keep llms.txt short and factual, and update it when prices or services change.
