Qu'est-ce que ChatGPT ?

ChatGPT is a general-purpose AI assistant from OpenAI. You type or speak a request and it answers in conversation, helping with writing, research, coding, analysis, learning and everyday questions. It runs in the browser and in desktop and mobile apps. It suits students, professionals and anyone who wants one assistant for many kinds of tasks. What sets it apart is its breadth: in a single chat it can search the web, read uploaded files, analyze data, create images and hold a voice conversation. Custom GPTs and saved instructions let you shape it around repeated work.
