Not because you were not paying attention. Because watching and learning are different things. This is what Ravenote does about it.
One button. Ravenote reads the transcript and writes the notes. Not a summary. The actual things you would have written yourself if you were fast enough and paying full attention the whole time.
You can sit through an hour of content and understand almost none of it. After your notes are ready, Ravenote asks you a few questions about what was just taught. Not to grade you. To show you which parts actually landed.
The gap between "I watched that lecture" and "I actually know that concept" is where most learning disappears. Ravenote tracks that gap for every concept across every lecture in the course. The bars do not lie.
The instructor explained it clearly. You still do not have it. Ravenote notices when you keep going back to the same section and offers to explain that exact concept using completely different language. Not a repeat. A different angle.
Generic notes do not work for everyone. Tell Ravenote what you are actually trying to get out of the course and it adjusts how it takes notes, what it pulls as concepts, and how it writes quiz questions. Once. Then it just works that way.
Better to know upfront than find out after installing.
Install it, open a lecture you have been putting off, and find out if it is actually useful for how you learn. Takes 30 seconds to set up.
