Similar(ish) boat, but I never got as into as you, really sorry to hear that and really proud you are trying to get away from it. I used the very first version of ChatGPT to get through a very annoying CS class (yeah, it was a really bad class). I messed around with some small local models in Ollama, but eventually realized I was too dependent on technology as a whole. I was using DuckDuckGo to get answers to questions I should be working through myself and using AI to take notes I would never reference. So I actually started sitting down and reading the textbooks, Wikipedia, and carrying a physical notebook (yeah, I know, way old-school). I started downloading information in forms I knew was AI-free (like Wikiepdia from 2024), and working offline. Even went so far as to ditch my phone this semester. It ended up working really quite well for me. I started getting much better grades in some really hard classes like aerodynamics, and annoying entry-level classes like thermo. So, really, my suggestion boils down to, read. Read encyclopedias, textbooks, and documentation. phone, bad book good.
