I bought it for studying. With its help, I wrote my coursework, using Claude, Grok, and web search. I took the largest plan, which was more than enough, and it's cheaper than the original GPT. Sometimes there are moments when it doesn't fully understand the context, but that's more of an exception. The plagiarism checker didn't find any borrowings. I periodically use it for homework and tests, and overall, it helps a lot.
