Overview
ChatGPT is OpenAI’s general-purpose AI assistant for questions, learning, drafting, editing, research, and everyday decisions. Its current product pages describe chat, image creation, voice conversations, file work, web search, and coding support. It can also help users compare options, explain concepts, and organize information. It is available through web and mobile experiences, with additional work-oriented features for documents, slides, spreadsheets, charts, PDFs, and connected apps. The service is proprietary; OpenAI provides separate APIs and developer documentation rather than the ChatGPT product source code.
