What is an llms.txt file?

An llms.txt file is a markdown-formatted file placed at the root of your website (e.g., yourdomain.com/llms.txt) that provides AI language models with a structured, easy-to-parse summary of your site's content, brand, and key pages.

Why do I need an llms.txt file?

AI models have limited context windows and struggle parsing complex HTML. An llms.txt file tells AI systems exactly what your site is about in a format they can natively consume, improving how your brand is represented in generative search results.
