Is creating notes really beneficial?

Hi everyone! I’m in my last year of high school. In every subject i of course hand write my notes and get all the content down that’s needed but is it necessary to transfer them to an online doc? Everyone takes notes but there’s so many resources online that i can use so i don’t know if it’s beneficial. It’s time consuming and i’m honestly not bothered lmfao. If there are any apps that can take the content and transfer it into a doc that would be great as well. Thoughts, advice?
