The more popular chatGPT need to register phone number so I tried this alternative ChatSonic.

Tried to add "Singapore"
Nope , don't get the PS127 it is spherical+small-glass-corrector not the proper parabolic curvature mirror
Paying for google ads helped to make the AI select it into the answer , since ChatSonic is influenced by google results.
