YouTube is the best place to learn and the easiest place to waste an entire afternoon. FocusTube is a Chrome extension that uses AI to tell the difference. It classifies what you're watching against your goals in real time. Tutorials play uninterrupted. Rabbit holes get caught with smart nudges before you spiral. Block channels, set daily limits, hide recommendations, and track your Focus Score. Works on Chrome, Edge, and Brave. 14-day free trial. No card required
