llms.txt explained: the AI-readable summary of your website
llms.txt is an experimental text file that bundles your key facts and links as an optional briefing. Whether an AI system fetches or uses it depends on the provider.
At a glance
llms.txt is a plain-text (Markdown) file at the root of your domain. It can bundle identity, offering and key pages in one place. It does not replace crawlable HTML or structured data, and adoption by AI systems is not guaranteed.
What is llms.txt?
llms.txt is an emerging convention for a file at /llms.txt that gives large language models a curated, machine-readable overview of your site. Instead of letting an AI infer your identity from scattered pages, you state it directly: name, what you do, for whom, and links to the pages that matter.
What it may provide
A focused llms.txt can offer supporting systems a compact set of facts and relevant links. Actual retrieval, processing and any visibility effect are not reliably established today. klarava therefore treats it as an optional, experimental signal.
What belongs in it
- A title and one-line summary of who you are and what you do.
- A short paragraph with the essentials: offering, audience, what makes you relevant.
- Links to key pages grouped by section (product, docs, about, contact), each with a short description.
Example

How klarava helps
The full report can generate an llms.txt draft tailored to your pages. Review facts and links before publishing it; the file is an optional addition, not a guaranteed visibility lever.

Where does llms.txt go?
In the root of your domain, reachable at https://yourdomain.com/llms.txt, as plain text (Markdown).
Is llms.txt an official standard?
No. It is an experimental, community-driven convention. Not every AI system fetches it, and a visibility effect is not guaranteed.
Does llms.txt replace good HTML and structured data?
No. It complements them. Your pages still need to be crawlable, server-rendered and structured. llms.txt is a concise, agent-readable summary on top. More on GEO & AEO
