This is an amazing extension!! The ability to chat with anyone, anywhere and on any website is genius!! I look forward to talking with and meeting people from all over the world. I can't wait to see where this extension goes- it feels like the next big thing!!

Erika Almodovar·17 Jun 2021

idea is very good but it needs more users and that global chat need not to be there it doesn't make any sense. only website specific chat is required since global chat feels like chatting on omegle.

Suman Sourav·7 Feb 2021

I guess this idea was like one of those eureka moments !!!
