What is ChatGPT?
ChatGPT is an AI chatbot made by OpenAI. You type a message, and it replies in plain language, a bit like texting a very knowledgeable helper.
People use it to write emails, explain difficult topics, brainstorm ideas, plan trips and study for exams. It launched in November 2022 and is now one of the most widely used AI tools in the world.

Clear explanations, practice questions and Study Mode for step-by-step help.
Professionals
Emails, reports, summaries and brainstorming in seconds.
Everyday users
Recipes, trip plans, gift ideas and quick answers to everyday questions.
How does ChatGPT work?
ChatGPT runs on a large language model, a type of AI trained on huge amounts of text. It learned the patterns of language, so it can write a helpful, natural reply to almost anything you ask.
It can also use tools: searching the web for current information, reading files you upload and creating images. Because it predicts answers instead of looking them up in a fixed database, it can sometimes make mistakes, so check important facts.
