Show HN: Instantly generate /llms.txt to make your website AI-readable

Hey HN,

I just built a small web app that helps you generate /llms.txt files for your website: https://llmstxt-cyuh.vercel.app GitHub: https://github.com/mandarwagh9/llmstxt

What is /llms.txt? Think of it like robots.txt, but for large language models. It’s a new emerging standard that gives LLMs a clean, Markdown-based map of your most important content (docs, guides, APIs). Instead of crawling bloated HTML, they get straight to the point.

The idea was popularized by Jeremy Howard and is gaining adoption across devtool companies like LangChain and Mintlify.

Why I built this I wanted a dead-simple way to auto-generate /llms.txt from any docs site or URL. This tool scrapes your site, extracts key Markdown links, and gives you a copy-paste-ready llms.txt.

No setup, no install, just paste your URL and download.

Stack

Frontend: Vercel + vanilla JS

Backend: Uses Gemini API (but can swap in any LLM)

Built with a focus on minimal UI + performance

Would love feedback, feature ideas, or suggestions for edge cases to cover (like private docs, multi-language support, etc.)

Thanks!

The link https://github.com/mandarwagh9/llmstxt is broken, and gives 404.

I assume this is to help tool-enabled agents navigate websites? I'm curious how this balances against the otherwise anti-LLM position a lot of website owners / artists are taking.

The link originally pointed to the GitHub repository, but I've made it private for obvious reasons.

The purpose of this file is to help AI scrapers index your website more effectively. OpenAI and other platforms are planning to prioritize these files, which can reduce scraping costs and improve the quality of indexed content.

This also gives your site an advantage in AI-powered search engines like Perplexity and ChatGPT Search.

For anyone in the emerging tech space, adding this file is a no-brainer — it can significantly improve your site's visibility compared to others.
