Not bad

I’ve still got privacy concerns because I know this is getting up stored somewhere so it’s like an earworm, you keep going back to it to ask questions and then you feel guilty. But hey, this is how AI works so I’m going to use it as assistive intelligence. It’s like I am engineering it so I like having a part of my didactic memory right here on my phone. It’s just my own database- the only issue is. Can somebody create a duplicate of me? So authentication is absolutely essential.

Reported Bugs

3 issues

Takes a long time to load if it can even answer. Waste of time and money.

Bug

The app is really slow and it always answers to where you have to scroll up to start. Also, there is no audio, which is disappointing. And whenever you ask a question, you always have to scroll up on an iPhone 12 to see the box where you type. It's just a little thing, but it's annoying. I was hoping for better and hopefully in time this will be better. Thank you.

Bug

I have only had this version for 5 minutes and it has already asked me for feedback. I just want to try it for three days but see that I am 'subscribed.' So how go I cancel should this version not work out. And, if it is working, how do I find the rules for use? Thank you
