Do you see how websites today get discovered by Google and also by AI tools like ChatGPT, Perplexity, and Claude? If your content is something you’d like to be accessed by these AI engines, there’s something new you should know: llms.txt.
It’s also called the new robots.txt of AI discovery. Let’s find out what Large Language Model Text is, how to create it, and how to optimise it so that AI tools will be able to get to know your website better.
What Is llms.txt?
In simple words, llms.txt is a plain text file, and it acts as a map for AI crawlers and language models (LLMs). It guides them on where on your site they can read, use, or skip, so they understand your content better when generating responses.
Think of it as an AI directional sign, because it shows AI engines the right path to discover your brand or blog content. Large Language Model Text gives them clear directions, but it also reduces confusion.
Just as robots.txt guides search engines to crawl, Large Language Model Text guides AI discovery, and therefore improves visibility.
Why You Require an Large Language Model Text File
AI technology is already web-crawling for information, but without Large Language Model Text, it may miss context. Because of this, AI systems could use your content incorrectly, and so the meaning becomes unclear.
Some of the most important benefits of Large Language Model Text for SEO are clear and powerful:
- It enables better comprehension of your brand content by AI engines, and so improves accuracy.
- It ensures product pages, guides, or blog posts are being used correctly, because context is preserved.
- It builds authority by giving AI systems permission to cite your website, and therefore improves trust.
- It creates an AI-friendly website sitemap for better indexing, so future AI-powered searches work effectively.
To make your website AI-discovery-ready, just like Digi Segment, you should implement Large Language Model Text.
Think of it as an AI directional sign, because it helps engines discover your brand or blog content. Large Language Model Text gives them clear directions, and it reduces confusion.
Just as robots.txt guides search engines to crawl, Large Language Model Text guides AI discovery, and therefore visibility.
llms.txt vs Robots.txt
You’re probably thinking, “Aren’t I already using robots.txt?”
Yes, but there’s a difference:
- robots.txt → Created specifically for search engines like Google, Bing, or Yahoo.
- llms.txt → Created for language models and generative engines.
So, while robots.txt diverts unwanted bot crawling away from you, Large Language Model Text deals with AI models. They coexist but have different roles.
llms-full.txt vs llms.txt
A common point of confusion arises when comparing llms-full.txt with llms.txt.
- llms.txt → Basic file with basic rules regarding what AI can fetch.
- llms-full.txt → More detailed, often with framed examples, metadata, and broader permissions.
Novice users will be fine with Large Language Model Text. Power users can turn to llms-full.txt for greater control.
How to Create llms.txt
Developing an Large Language Model file is simpler than it may initially appear. Here’s a quick tutorial:
- Open a plain text editor like Notepad.
- Type simple instructions on what AI tools can and can’t see.
- Save the document as llms.txt.
Upload it to your root directory of your website (like robots.txt).
llms.txt Format and Markdown
You can leave Large Language Model bare, but most webmasters today use markdown for easier reading.
Best Practices for llms.txt
If you desire your file to work at its best, follow these Large Language Model best practices:
- Keep it short and simple.
- Use a consistent style.
- Include an AI attribution contact or source URL.
- Update it whenever you publish new meaningful content.
Try out your file using an Large Language Model generator tool to test for errors.

FAQs
llms.txt is a plain text file placed in the root directory of a website. Its purpose is to guide AI crawlers and large language models (LLMs) on what parts of your website they are allowed to access, use, or ignore. It works similarly to robots.txt but is designed specifically for AI discovery and generative engines.
While both files act as instructions for crawlers, their audiences differ. robots.txt is meant for traditional search engine bots like Google or Bing, whereas llms.txt is designed for AI platforms and language models such as ChatGPT, Perplexity, or Claude. In short, robots.txt manages search engine indexing, while llms.txt manages AI-driven discovery.
llms-full.txt is a more detailed version of the standard llms.txt file. Instead of just providing basic access rules, it can include structured examples, metadata, and additional context for AI crawlers. This gives webmasters more control over how AI models interpret and use website content.
