llms.txt Checker

An llms.txt file is a structured text file that you place in the root directory of your website, similar to robots.txt. The difference is that llms.txt is specifically designed for AI search engines and large language models. The file tells tools like ChatGPT, Claude, and Perplexity exactly what your business does, which products or services you offer, and how users can contact you. Without this file, AI must try to interpret your website on its own, which often leads to incomplete or incorrect information.

The shift from traditional search engines to AI tools is already in full swing. Millions of people worldwide use ChatGPT, Perplexity, and similar tools daily to find answers to their questions. When someone asks "What's a good bakery in Amsterdam?" or "Which company can design my website?", you want AI to know your business and recommend it. A well-crafted llms.txt file increases the likelihood that your website will be included in the answers AI gives to these users. This is the next step in online visibility, after SEO for Google.

Setting up an effective llms.txt file requires more than just a list of links. The content must be structured according to a specific format that AI models can process efficiently. Your business description must be clear and concise, your services must be properly categorized, and your contact information must be complete. Our tool analyzes your entire website and automatically generates a professional llms.txt file that meets all requirements.
