A Complete Guide to llms.txt: Everything You Need to Know about llms.txt
As large language models (LLMs) become deeply embedded in modern websites, apps, and digital platforms, the need for transparency in AI usage is more crucial than ever. Enter llms.txt — a simple yet powerful file designed to disclose how AI models are being used on your digital property.
In this complete guide, you’ll learn what llms.txt is, why it matters, how to structure it, and how to implement it effectively.
Introducing llmstxt.org
To encourage widespread adoption, llmstxt.org has been launched as the official hub for the llms.txt initiative. This platform offers:
- Detailed documentation on creating and structuring llms.txt
- Easy-to-use templates for quick setup
- Real-world examples from active websites
- Best practices for ethical and transparent AI implementation
- Tips to ensure compliance with regulations like the EU AI Act
The project is open-source and community-driven, making it easier for developers, businesses, and regulators to adopt standardized AI disclosure practices.
As a leader in ethical AI integration, DGTLmart supports the llms.txt initiative to promote responsible AI use across digital platforms.
What is llms.txt?
llms.txt is a plain text file hosted at the root of a domain (e.g., https://yourdomain.com/llms.txt). Modeled after robots.txt, it allows organizations to publicly share information about the LLMs they use—what they’re used for, who provides them, and how user data is handled.
It supports the growing call for transparency in AI usage, especially in light of increasing regulatory oversight.
Why Use llms.txt?
As powerful generative AI models like GPT-4, Claude, and Gemini are integrated into more digital services, it’s important to:
- Use AI ethically
- Disclose AI-generated content
- Respect user privacy
- Build trust with your audience
- Comply with AI regulations
DGTLmart encourages the use of llms.txt for organizations looking to maintain AI compliance and transparency at every touchpoint.
llms.txt makes all of this easier by offering a simple, standardized disclosure format.
Where Should You Place It?
The llms.txt file must be hosted at:
https://yourwebsite.com/llms.txt
Placing it in the root directory ensures easy access for users, crawlers, and compliance auditors.
