Marcus - Markdown For AI by locustfist

Marcus browser extension is a tool for Firefox that converts web pages, specifically articles and blog posts, into clean and readable markdown files.

It works by intelligently extracting the main content from a webpage, removing clutter such as ads, navigation menus, and sidebars. The user can then view the extracted content in a slide-out panel, either as a formatted preview or as raw markdown code. The extension provides options to copy the content to the clipboard or download it as a .md file. All processing happens locally in the browser, ensuring user privacy.
