YouTube talks. Guru lets you talk back.

A lecture is one-way: the presenter speaks, the student listens. Guru turns any YouTube lesson into a two-way class — ask questions mid-video, extract the important points, take notes in 8 languages, revise with frameworks and sit an exam on exactly what you watched.
