Flashcard and Practice Test Generator for Study Notes

I like to make my own notes from lectures and study material (lecture slides, books, articles, pdfs) but after that I'm not the best about studying the material I've created. I've noticed tools where I can upload my notes and use flashcards and practice tests really help. I've tried a few services such as Studley (it was always adding weird terminology or strange structuring/formatting that made actually learning difficult. It also felt really shallow) and I've tried Gradius (big fan in the beginning, took a break to try Studley and came back to it and it was genuinely phenomenal. It made me connect ideas and compare and contrast topics and made me really reach deep. However, the site has been down for like a month now and that seems to happen frequently. Devs/founders have gone absolutely silent when they used to be active on Discord. Somehow the sites being down almost always aligned with me having a big quiz coming up so I never got to see if there was a payoff). I've also tried Google Notebook and couldn't get it figured out in a way to be meaningful. Now I've tried Study Fetch. It seems okay. I've only used it for about 2 days but there doesn't seem to be the problem I had with Studley. The app is admittedly not the best but that's not a deal breaker by any means for me. I also don't particularly care about summarising tools or AI chat stuff, the big things for me are flashcards, practice tests, and podcast tools are pretty cool too. So, could I get some recent feedback? I've seen very mixed reviews from the last year and I'm not sure if I should take the plunge with a subscription. If anyone uses any other tools they'd like to mention I'm all ears! If it matters at all I'm studying social services.
