Ratings and reviews

the UI is clunky in general. on top of that, the AI is weak, and requires you to buy premium if you want to use it for more than a few times per day. when you type your question to the AI, your phones' keyboard blocks the textbox, so you can't see what you're typing. when you look through the cards, it doesn't even have an option to view the upgraded versions. you're better off using chatgpt and google
