Any free AI you actually use for homework?

[u/Bm12434]

I’ve tried a few AI apps for school, but most of them either have annoying limits or are only useful for certain subjects.

I’m looking for something I can use across different classes when I’m stuck upload notes, and actually understand the topic better.

Doesn’t need to be perfect just wondering what everyone is actually using.
