llms.txt is the new standard for communicating with AI systems. Like robots.txt tells search engines how to crawl your site, llms.txt tells AI models what your business does, what services you offer, and how to accurately represent you. We implement and maintain llms.txt files that ensure AI systems describe your brand correctly.
What Is llms.txt?
**llms.txt** is a proposed standardised text file placed at the root of your website that provides AI language models with structured information about your business. It's designed to be the robots.txt of the AI era — a simple, machine-readable file that tells ChatGPT, Claude, Perplexity, and other AI systems who you are, what you do, and how to accurately describe you. Without llms.txt, AI systems rely on whatever information they can find, which often leads to incomplete or inaccurate brand representations.
Less than 1% of websites currently have an llms.txt file — early adopters gain a significant visibility advantage

What is llms.txt?
llms.txt is a text file placed at your website's root (like robots.txt) that provides AI language models with structured information about your business. It tells ChatGPT, Claude, Perplexity, and other AI systems who you are, what you do, and how to accurately represent you.
Is llms.txt an official standard?
llms.txt is a proposed standard that's gaining adoption. While not yet universally formalised like robots.txt, major AI platforms are increasingly recognising and using llms.txt files. Early adoption gives you an advantage as the standard matures.
Which AI platforms use llms.txt?
Claude (Anthropic) actively supports llms.txt. ChatGPT and other platforms are beginning to recognise it. As the standard gains adoption, more platforms will use it. Having llms.txt ready positions you for immediate benefit as each platform adds support.
What's the difference between llms.txt and llms-full.txt?
llms.txt is a concise summary — your brand identity, core services, and key facts in a brief format. llms-full.txt is the comprehensive version with detailed service descriptions, case studies, team bios, and extended brand information. We typically create both.
How is llms.txt different from robots.txt?
robots.txt tells crawlers what pages to access. llms.txt tells AI systems about your brand identity and how to represent you. They serve different purposes — robots.txt controls access, llms.txt controls representation. You need both for optimal AI visibility.
Do I need llms.txt if I already have good schema markup?
Yes. Schema markup helps AI systems parse individual pages. llms.txt provides a holistic brand overview — your identity, positioning, services, and how you want to be represented. They're complementary, not redundant.
How long does llms.txt implementation take?
Initial creation and deployment typically takes 1-2 weeks, including the discovery interview, draft writing, client review, and deployment. The file itself is simple — the value is in getting the content right.
How much does llms.txt implementation cost?
llms.txt implementation is one of our most affordable services. It's a one-time project with optional quarterly maintenance. Contact us for a quote based on your business complexity.
Can I write llms.txt myself?
You can, but most businesses benefit from professional implementation. We know what AI systems look for, how to structure the information for maximum impact, and how to avoid common mistakes that reduce effectiveness.
What happens if I don't have llms.txt?
AI systems will still describe your brand — they'll just use whatever information they can find on the web. Without llms.txt, you have no control over how AI represents you, which often leads to incomplete or inaccurate descriptions.
How often should llms.txt be updated?
We recommend quarterly reviews and updates whenever your business changes significantly — new services, team changes, product launches, rebranding, or strategic shifts. Keeping llms.txt current ensures AI representations stay accurate.
Where does the llms.txt file go?
At your website's root — accessible at yourdomain.com/llms.txt (and yourdomain.com/llms-full.txt for the extended version). This is the same convention as robots.txt and sitemap.xml.
Will llms.txt help my Google rankings?
llms.txt primarily targets AI language models, not Google's traditional search algorithm. However, it contributes to overall AI visibility, which increasingly influences Google AI Overviews. It's a complement to SEO, not a replacement.
Can competitors see my llms.txt?
Yes, llms.txt is a public file (like robots.txt). This is by design — AI systems need to access it freely. The competitive advantage isn't in secrecy but in being among the first to implement it and getting the content right.
What should llms.txt include?
A good llms.txt includes: company name and description, core services or products, target audiences, geographic coverage, key differentiators, team expertise, and any specific instructions for AI representation. We structure all of this in the format AI models prefer.
