Web2md: Chrome extension to copy webpage as Markdown

That looks like a <i>really</i> old version of turndown.js, pre-ES6. The link to turndown in the readme is the old one, too. How long ago did you make this? Anyway, you need to put turndown&#x27;s license in the js file or someplace if you&#x27;re not going to use npm for some reason.

If you use Joplin, their extension for Chromium-based browsers will also copy pages as Markdown and save them to your (encrypted) notebook in Joplin.
