About

What is markdowner?

Markdowner is a fast and free tool designed to convert any website into LLM-ready markdown data. Built by Supermemory.ai, it addresses the need for structured and predictable data when interacting with Large Language Models, leading to much better AI responses. Key features include LLM filtering to remove unnecessary information, a detailed markdown mode, and an auto-crawler that works without a sitemap. It supports both text and JSON responses and is easy to self-host. The tool utilizes Cloudflare's Browser rendering and Durable objects to spin up browser instances and convert content to markdown using Turndown, offering a robust solution for data preparation.
