llms.txt Generator

Automatically generate and host a clean llms.txt file so supported AI tools can understand your most important pages without guessing from messy HTML.

llms.txt is a plain-text file, proposed in 2024, that gives AI systems a curated map of your most important pages with short descriptions. Writing one by hand goes stale the moment you publish something new. geodeck generates yours from your live sitemap, hosts it on your domain, and updates it automatically whenever your content changes.

What is llms.txt?

What is llms.txt and why does it matter?

llms.txt is an emerging proposal, inspired by robots.txt, for giving AI tools a concise Markdown map of the most important pages on your site. It can help supported tools understand your site structure, but it is not a ranking guarantee and Google says it is not required for Google AI Search.

yourdomain.com/llms.txt
# My Site - AI overview

> A short description of what my site is about and who it's for.

What do IndexNow, Google, and schema.org say about hosted files?

Hosting llms.txt at your domain root works the same way IndexNow ownership verification does: a plain text file living at a known path. Google's AI features documentation is explicit that no such file is required for its own AI features, which is why geodeck treats llms.txt as an addition, not a replacement for the structured data schema.org's getting-started guide recommends, or for the Markdown format the file itself is written in.

To submit URLs, you must "prove" ownership of the host for which URLs are being submitted by hosting at least one text file within the host.

FAQ

What questions do people ask about llms.txt?

llms.txt is a plain-text file at the root of your website (like /llms.txt) that tells AI language models which pages and documents on your site are most relevant. It follows a simple Markdown-inspired format with sections and links - think of it as a table of contents for AI crawlers.

Some AI tools and documentation platforms are experimenting with llms.txt, but adoption is not universal. Treat it as a helpful machine-readable map that complements canonical HTML, sitemap.xml, robots.txt, schema, and strong content.

llms.txt is a lightweight index that links to your key pages. llms-full.txt is a richer version that includes the full Markdown content of those pages inline - useful for AI models that want to read everything in a single request. geodeck can generate both formats automatically.

Not with geodeck. You add your domain, verify ownership once, and geodeck generates and hosts /llms.txt on your domain automatically - no server access, no code deployments, no plugins required.
