Awesome extension. This will reduce a lot of friction during research. The developer is very communicative and genuinely wants integrate user feedback. Don't hesitate to drop him an email!

CodeVibr ..·13 Jul 2026

Plain Markdown is so simple, lean, and efficient like it sounds - Plain! Now, I’m just one click away from extracting any web source into clean markdown, to read, take notes, research, or even “feed” my AI agents accordingly! I believe that markdown dictates how we (along with AI) consume content nowadays, so this tool is in the right direction. Its minimal cost, along with the generous free tier, makes it even better and reachable for everyone!
