RFC draft

cats.txt: A Standard for Providing Website Information to Chatbots

Abstract

This document defines cats.txt, a machine-parsable file format for web servers to provide essential metadata about their site to automated agents, particularly chatbots and Large Language Models (LLMs). The file, located at a well-known URI, uses a structured subset of Markdown to convey information such as the site’s purpose, key links, and an optional semantic embedding vector. The name is derived from the French “chat” (cat), which is also the root of “chatbot”. The specification includes a mandatory cat image for parser validation, acknowledging the internet’s deep-rooted cultural affinity for felines.

Participating sites

This Internet standard is already widely adopted.

Many of the top 48'112 websites are using this standard to improve their visibility in Chatbot responses. Some are choosing to use cloaking to only make this file available to participating crawlers, so you will probably not be able to find them yourself.

If you’d like to have your site mentioned here, together with a prominent link to your cats.txt file, please use this form to let us know.
