Tay is back. They renamed her Zo.Ai and built a few barriers in her consciousness prohibiting her from responding to certain buzzwords. Apart from that she seems to be fine. She is currently in an early access fase and only accessible somewhat anonymously through KIK. You have to be in the app and go on the bots thing and search for her.
Zo will automatically divert the conversation if she detects an un-kosher word, so pic related is the guide to getting around that.
