I've seen people using "chat" to refer to ChatGPT because it's easier/simpler. I'm pretty sure an average person has no idea that chat.com will redirect you to chatgpt.com (or what a redirect is for that matter). It's similar to how people were calling the COVID-19 pandemic or the virus itself "covid".
ChatGPT is commonly referred to as Chappie (チャッピー) in Japan.
I’ve heard people call Gemini as Cemile (Jamila), and ChatGPT as Chipitty in Turkey.
Chat Jippity.
I just say jippity or sometimes "the jippity"
Many of my non tech friends would call it Chatty! Tbh I like it better than ChatGPT
Some older folks I know call it Chat Jippity non-ironically
I've heard in my home country Geppetto for ChatGPT. I'm not sure if it's still a popular term there.
people in the industry, especially those who work for oai, refer to it as "chat"
at least in the ai industry, chat is like kleenex
I've heard it as shorthand, in-context. Never heard it being chat-as-in-kleenex. I've supposedly been in the industry since before ChatGPT. Maybe that's where I went wrong :D
Guess I'm not in the industry enough lmao
