Managed sites

Set it once. Never stale.

A generate call makes a file once. A managed site keeps it current โ€” forever. We regenerate on your schedule when your content changes, and serve the freshest version from a stable URL.

  • Always current โ€” auto-regenerates weekly or daily, and only when your content actually changes.
  • One line to connect โ€” point your /llms.txt at a stable URL, or have it pushed to your webhook.
  • No runtime dependency โ€” commit it straight into your repo on every change and serve it from your own infra.
  • Built to scale โ€” agencies and platforms manage up to 250 sites from one account.

It's a simple markdown standard โ€” proposed by Jeremy Howard of Answer.AI โ€” that gives AI coding assistants and agents a clean, machine-readable map of your docs. Here's what a well-structured file looks like.

Structured for AI agents

The llms.txt format uses simple markdown that both humans and AI can read.

  • โ€ขH1 title defines the project or site name
  • โ€ขBlockquote provides a concise summary with key information
  • โ€ขH2 headers organize documentation sections logically
  • โ€ขOptional section marks secondary or supplementary resources
  • โ€ขClear links to important content with descriptive text
# Project Name

> Project description with key information necessary
> for understanding the documentation.

Frequently Asked Questions

Common questions about llms.txt and llms-full.txt files

What's the difference between llms.txt and robots.txt?

No! While popular for tech docs, llms.txt works for any website - e-commerce, blogs, corporate sites, and portfolios.
