Meaning

OpenAI's AI chatbot; the tool that introduced millions of Japanese people to generative AI in 2023, often shortened to GPT or チャGPT.

ChatGPT became a cultural phenomenon in Japan in 2023, with its usage spreading from tech enthusiasts to students, office workers, and creators almost overnight. Japanese users frequently shorten it to GPT (ジーピーティー) or affectionately write it as チャGPT. Discussions range from practical uses like writing emails and summarising documents to concerns about academic cheating and job replacement. The term is now part of everyday Japanese tech conversation.

Examples

1. レポートの参考にChatGPT使ったら先生にバレた。 I used ChatGPT as a reference for my report and my professor caught on.
2. ChatGPTに頼んだらめっちゃいい文章書いてくれた。 I asked ChatGPT and it wrote me an amazing piece of text.
3. このメール、ChatGPTで作ったっしょ？なんか硬いんだよね。 This email — you had ChatGPT write it, didn't you? It sounds way too stiff.
