If a prospective employee told me a story about how they used a note-taking app like this to optimize their school grade output I would be extremely worried for a lot of reasons and consider it a major red flag.

What would be encouraging is an app that does not REPLACE your note taking but rather amplifies the capabilities.

You must take notes to learn deep. Handwritten is very important.

You will miss some things, which an AI could be tracking and summarize

What I would consider valuable is an app that supplements your notes. It would need two components... the app you have now, and reading in the notes that you have taken. Then if you asked it to go deep on a particular note or section you took notes on, it could add to the notes that you took without stealing the important part of the learning process
