llms.txt Generator

Understanding llms.txt

llms.txt is a configuration file that allows website owners to control how Large Language Models (LLMs) can access, index, and train on their content. Similar to robots.txt for search engines, llms.txt gives you control over AI model access to your site.

Why Use llms.txt?

• ✓ Protect your content: Control which AI models can access your material
• ✓ Manage training: Decide whether your content can be used for model training
• ✓ Require attribution: Demand proper credit when your content is used
• ✓ Path-specific rules: Allow different access for different sections of your site
• ✓ Future-proof: Be prepared as AI integration increases

How to Install llms.txt

Once you generate your llms.txt file:

1. Download or copy the generated content
2. Create a .well-known folder in your website root if it doesn't exist
3. Place the llms.txt file at: /.well-known/llms.txt
4. Verify it's accessible at yoursite.com/.well-known/llms.txt

Will llms.txt stop LLMs from accessing my site?

Not entirely. Some LLMs may not respect llms.txt directives. However, responsible AI companies will honor the configuration. It's similar to robots.txt — it's a standard that ethical actors follow.

Do I need both robots.txt and llms.txt?

Yes. robots.txt controls search engine crawlers, while llms.txt controls AI model access. They serve different purposes and can have different rules.

Which LLMs respect llms.txt?

Major models like ChatGPT, Claude, Gemini, and others from responsible companies are adopting llms.txt support. Smaller or less scrupulous models may ignore it.

Can I update llms.txt later?

Yes! You can regenerate and update your llms.txt file anytime. Just replace the existing file with the new version. Changes take effect immediately.

Is llms.txt an official standard?

llms.txt is a growing standard in the AI community. Visit llmstxt.org for official specifications and updates.
