Web highlighter prompts users to explain highlights for better learning

A developer has created Markpin, a free Chrome extension designed to improve learning from online articles by incorporating active recall principles. Unlike simple bookmarking, Markpin prompts users to explain why they highlighted a sentence, saving this explanation alongside the quote in Markdown format. The extension utilizes IndexedDB for storing page content and clips, while chrome.storage manages user settings, and the saved data is structured into Markdown files with machine data embedded in HTML comments for compatibility with tools like Obsidian.
