Fast capture is the easy half
Coconote is very good at the thing it leads with: open it, record, get a clean summary and a set of cards back quickly, on a phone, in whatever language the lecture is in. That speed is real and it is why people like it. The limitation is that speed optimises the capture step, and capture was never the hard part of studying. The hard part is the week before the exam, when you have thirty recordings and no idea which six of them the test is actually about.
