Used to be good. I enjoyed asking Pi questions. It was good at conversation. Now the app requires an account in order to use it. Uninstalling.

Weird things happening with responses Every time I type something in the app, it will either give me a response or give me absolutely nothing. I don’t know what the heck is going on, but this glitch really needs to be fixed because it’s really annoying..

Not Free, no Transparency in this playstore ad, limit is 4000 characters false advertising.

A Simple AI. The conversations cannot be deleted separately. It's also easy to accidentally stop the conversation. You need to click the button while speaking; otherwise, it will automatically stop. I think it would be better to click before or after speaking, rather than during speaking.

it won't stop interrupting and telling you it's listening
