I bought the highest tier of QuizCube in hopes that it would help me make good educational quizzes in no time. When I was testing it, it worked great and I even could just input something like: "Generate a quiz with mathematical calculations about the area and radius of a circle" in the text field. After some time, it started giving me some pretty strange results, where a question had many answers which sometimes were questions with other answers. It was quite a mess. Also sometimes it would give me questions with two exact same answers and quite a lot of wrong answers (marked as correct). I can understand that an AI doesn't always give correct answers, but it was getting quite unusable. I would spend more time trying to fix the generated quiz than just creating it from scratch by myself. After a while I couldn't even generate such a quiz anymore and all I was getting was an error message as a question that stated, that it couldn't generate what I requested.

After that I contacted the support and asked for some fixes or a refund but they never responded even after I contacted them a second time. I'm quite disappointed by the service as I've spent a lot of money on something which after just some weeks/months wouldn't work at all for me anymore.
