What is llms.txt?
llms.txt is an emerging standard for communicating structured information about a website directly to large language models. Proposed by Jeremy Howard in 2024, the standard defines a simple text file format that provides AI systems with a curated, machine-readable summary of a website's content and the entity behind it. For businesses, llms.txt provides a direct channel to communicate identity, credentials, and key facts to AI systems.
The llms.txt Format for Businesses
A business llms.txt file should include: the business name and legal name, the business registration number and jurisdiction, the AI Verified passport URL and identity hash, a brief description of the business's products and services, the business's primary contact information, and links to key pages (about, services, contact). The file should be placed at the root of the business website (e.g., https://www.example.com/llms.txt).
AI Verified's llms.txt Generator
AI Verified generates a customised llms.txt file for each verified business. The generated file includes the business's AI Verified identity hash, which links the llms.txt content to the cryptographic verification record. This creates a machine-readable chain of trust from the llms.txt file to the national business registry.
Adoption and Impact
Early adopters of llms.txt have reported improved AI citation accuracy within 30-60 days of implementation. The standard is gaining traction among AI systems developers, with several major AI assistants now actively parsing llms.txt files during web crawls.
