What it does

mdream converts HTML to markdown quickly, optimized for large language models and streaming, allowing founders to easily convert HTML content to markdown format

When to use it

•You need to convert HTML blog posts to markdown for a new website
•Your team wants to migrate HTML documentation to markdown for easier editing
•You're building a web scraper that needs to convert HTML pages to markdown for further processing

Ready-to-paste prompt

const html = '<h1>Hello World!</h1><p>This is a paragraph.</p>'; const markdown = mdream.convertHtml(html); console.log(markdown);

Heads up: Make sure you're using a compatible version of Node.js, as mdream is built with TypeScript and may not work with older versions
