Clipper

Clipper is a Node.js command line tool that allows you to easily clip content from web pages and convert it to Markdown. It uses Mozilla's Readability library and Turndown under the hood to parse web page content and convert it to Markdown.

Clipper provides a quick and simple way to save bits of content from the web for personal archival or note taking purposes, similar to browser extensions like Evernote Web Clipper or Notion Web Clipper. However, Clipper runs entirely in the terminal so you don't need to install any extensions or sign up for accounts.
