What is ChatGPT?
ChatGPT is a conversational AI assistant from OpenAI. You describe a task in plain language and it responds with drafts, explanations, summaries, tables or code. Most people use it for writing and editing, turning rough notes into structured documents, brainstorming and working through problems step by step.
Beyond chat, ChatGPT organizes work into projects, can read uploaded files on supported plans, and lets paid users build custom GPTs: reusable assistants with their own instructions. Business, Enterprise and Edu workspaces add administrative controls, and OpenAI states that content from those workspaces is not used to train its models by default.
Like every large language model, it can state incorrect information confidently. Treat its output as a draft, and verify facts, figures and quotations against primary sources before you publish or act on them.
What can you use ChatGPT for?

- Summarizing long documents or meeting notes you upload
