Best feature
very useful and helpful for learning
Pi Lens genuinely makes studying on YouTube way more effective. The notes, summaries, quizzes, and PYQs being available directly alongside lectures save a huge amount of time and make revision much easier. I especially like how clean and distraction-free the interface is, and the instant quizzes help test concepts right after learning them. It feels specifically designed for Indian students preparing for boards, JEE, NEET, and other exams. Definitely one of the most useful study extensions I’ve used.
