I used sign in for $2 and was claimed that I cancel at any time.I could not easily cancel. They keep forwarding me to payment page for adding my credit card information in subscription.The whole experience was disturbing. I was just communicating with AI. The answers where cliché and with no practical value. There were text book answers with no touch of reality of court and legal system.Finally cancelation cost me $28.16. Meanwhile I gort charged for the monthly fee of $86.Just a scam and indecent advertisement.
