Ratings and reviews

"Why does the 'Send' button appear instead of the 'Enter' button at the bottom right when the typing keyboard opens? When I'm typing or trying to add something to a new line, all the text ends up next to each other. This is a very inconvenient situation. I think you need to update this. There's already a 'Send' button (like an arrow) in the typing window. The ability to go to a new line by pressing 'Enter' must definitely be activated on the typing keyboard.

The app is really buggy, you should fix it. It gets incredibly slow when typing in the AI chat. We also should be able to organise and save chats. Chat history system is weak, it's not synced through devices and you can save specific chats. There should also be an option to save an AI note created in the chat. You have a separate AI Note feature, which is good, but also need to save the AI Notes that we create during the chat. Otherwise the app is really well thought. Congratulations.

Honestly, I spend more time in this app than I expected. I kept seeing this App in several social medias, at first I didn’t want to actually download this because usually it comes with a lot of payment or subscriptions. I downloaded it because I am left behind in my mathematics algebraic lessons so I downloaded it and not gonna lie I ACED my exam. I suggest this app, there are also NO DISRUPTIVE ADS—I can study whenever I want to without an ad interrupting me.
