LaserFocus is a free Chrome extension designed to transform passive video watching into engaging active learning sessions. It captures audio from the active tab, transcribes it, and generates multiple-choice questions (MCQs) at customizable intervals to keep users focused. The extension's features include a pro mode offering extended capabilities, support for multiple languages, and enhanced performance for longer sessions. Users can set question frequency and count, ensuring a tailored learning experience.

The extension's core functionalities include auto-pause for questions, a clean overlay for MCQs, and a strong emphasis on privacy, as it only captures tab audio without microphone access. LaserFocus is suitable for students and professionals seeking accountability during online lessons, providing a structured approach to learning that encourages retention and engagement.
