Try adding: /llms.txt to the end of an AI company’s documentation website. It’s basically a clean, AI-readable map of the website, written in Markdown so LLMs and AI agents can understand the important pages without fighting through navigation menus, JavaScript, buttons and all the other wonderful things humans added to websites. 😂 For example, several companies in the Voice AI / AI Agent ecosystem already use it: 🎙️ Vapi → /llms.txt 📞 Retell AI → /llms.txt 🤖 Bland AI → /llms.txt 🔊 Cartesia → /llms.txt 🗣️ LiveKit → /llms.txt ☎️ Twilio Docs → /llms.txt And it goes beyond Voice AI: 🔎 Perplexity uses it 🔥 Firecrawl uses it 🧠 Anthropic / Claude uses it 🌪️ Mistral uses it So what exactly is llms.txt? Think: robots.txt → instructions for crawlers sitemap.xml → map for search engines llms.txt → curated map for LLMs & AI agents Instead of forcing an agent to figure out an entire website, the file can point it directly toward things like: → Documentation → API references → Pricing → Tutorials → Integrations → Product information → Important Markdown pages Some sites even provide llms-full.txt, which can contain a much larger version of the documentation specifically designed to be consumed by an LLM. ⚠️ One important distinction: This isn't some secret "rank #1 in ChatGPT" SEO hack. llms.txt is still an evolving convention, and not every AI system is guaranteed to use it. But when companies building AI agents themselves are publishing these files, it's definitely something worth knowing about. And here's where it gets interesting for those of us building Voice AI… 👀 Imagine giving your voice agent, RAG system or research agent the /llms.txt file of documentation instead of telling it: "Go crawl this entire website and hopefully figure it out." Much cleaner. 🧪 Try it yourself: Find an AI tool you use, go to its documentation site and add /llms.txt. You might be surprised how many already have one. 👇 Has anyone here already added an llms.txt file to their own website?
