If you happen to find a good article filled with links you want to check out later, you usually need to save each one individually. GrabLinks is a bookmarklet that pulls every link out of the text you select, then turns that into a clean and easy to read Markdown list.
With GrabLinks installed in your bookmarks bar, you simply click the bookmarklet, and then select the section with links you want to collect. GrabLinks briefly does its thing, and then kicks out the links inside that page as a Markdown list. It's really handy when you're doing research.
