Horrible and mad

It doesn’t save my work ask me all the time how I need to down load what o told it to say I’m being charger for something I do all the work for I’m no longer going to pay for it sorry it tricked me at first then when I paid for it it turned bad

Please fix

The second I got on it said I had to pay… I don’t get why apps make you pay because you should just be grateful that people are even wanting the app… I want this app and I think it would be really great but nobody wants to pay to use an app!! I know you guys might not be able to fix it but if you can I would really like that because nobody wants to pay and you’re just getting less five star reviews so if you can please explain to me why you need us to pay…

I hate this.

I cant figure out how to use the app I paid for. The free version is user friendly and much better. I’ll be working to get my money back.

Has no idea what’s going on in the real world

This AI bought is horrible as it does not have any connections to the real human connection, which is all social media and other sites besides publications and journals. The app will never be a great app. If you cannot reach the human connection and what they are going through.

Response from developer

Thank you for your feedback, it's very valuable to us. Our AI models are trained on real data and have access to the internet. However, you may have a misconception about how AI models can be used. They are not designed to browse content on social media. In any case, please write to our support team and provide more detailed information about what exactly isn't working as you expect. This information is very valuable to us and will help us identify weak points in the app and fix them

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
