llms.txt
Definition: llms.txt is a proposed standard file that websites serve at their root domain to provide structured information to AI language models about their product, service, or content. It is similar in concept to robots.txt (which tells search crawlers what to index) but designed specifically for AI systems.
Detailed Explanation
An llms.txt file contains a structured summary of what your product does, who it is for, key features, pricing, and other information that helps AI systems accurately represent your product in generated answers. It provides a single, authoritative source of truth that AI crawlers can reference.
The file typically includes: product name and description, target audience, key features, pricing tiers, use cases, competitive positioning, and FAQ answers. Some implementations also include an llms-full.txt with extended documentation.
Why It Matters for Founders
AI engines synthesize information from many sources, which can lead to outdated or inaccurate representations of your product. An llms.txt file gives you a direct channel to communicate accurate, current product information to AI systems. It is one of the simplest AEO optimizations a founder can implement.
