Like other users, I haven't found that the documents provided by Studocu have been worth buying; they seem about on par with those provided by my university for free. Still good enough to be an average 3 stars.However, what I find very problematic and worth just 1 star is that the website is now filled with LLM chatbots. Chatbots for skimming documents, chatbots for taking quizzes, etc.To put it mildly: I find this abhorrent. For one, LLMs are still not competent at specialised topics, which people who use this website would ask for, and commonly hallucinate. But even more concerning, said AIs try to replace finding good papers and learning with other students, both of which are VITAL for students in higher education.Due to how much the website pushes "AI features" (half of the sidebar options are about AI) and due to how they must have known how bad of a fit LLMs are for this kind of platform, I can only assume they implemented these "features" because of the AI bandwagon. The fact they would intentionally reduce the learning quality of their platform just so they cram a buzzword feature into it tells me that they don't care about quality.Would it still have been 2 stars if the chatbots were more hidden away? Maybe. But with how Studocu shoves them into your face, begging you to learn in a worse way, it's deserving of just 1 star.
