For as long as the web has existed, we've had ways to communicate with machines: sitemaps tell search engines what to index, robots.txt tells crawlers where to go and where not to. These files are quiet infrastructure, working in the background so the visible surface of your site can do its job.
The AI era needs the same kind of infrastructure. And right now, most websites don't have it.
What is llms.txt?
The llms.txt standard is a simple, emerging convention: a plain-text file hosted at the root of your domain that tells large language models — ChatGPT, Claude, Gemini, Perplexity, and others — what your site is about, who you are, and how your content can be used. A companion file, llms-full.txt, goes further: it includes the full text of your site's key pages in a structured, AI-readable format.
The idea is straightforward. When an AI system needs to understand your content before surfacing it in an answer, these files give it something clean to work with rather than crawling raw HTML, wrestling with JavaScript rendering, or skipping you entirely.
What Seedfile does
Seedfile is a new Had A Farm product that takes the complexity out of the process. You enter your domain, Seedfile scans your site, runs a series of AI visibility diagnostic checks, and generates both your llms.txt and llms-full.txt files ready for download and deployment.
The diagnostic layer is what separates Seedfile from a file template. Before generating your files, it evaluates your site against a set of AI visibility signals: whether your key pages are crawlable, whether your content is structured in a way AI systems can parse, whether you have the basic signals in place that make a site worth citing rather than overlooking.
You get the diagnosis. You get the files. You drop them at the root of your domain and you're done.
Why now?
Answer engine optimization isn't a future concern anymore. It's a present one. A growing share of search queries are answered directly by AI systems, and those systems are making choices about which sources to cite and which to skip. The sites that get cited share common traits: clean structure, clear authorship, well-organized content, and the technical infrastructure to signal all of that.
llms.txt is part of that infrastructure. And right now, the overwhelming majority of websites don't have one.
That's a gap Seedfile closes in minutes.
Getting started
Seedfile is live at seedfile.app. Enter your domain, run your diagnostic scan, and download your files. Pricing is simple and the first scan gets you oriented.
