About ChatGPT
ChatGPT is OpenAI's conversational AI assistant, available through the ChatGPT app and web experience. It can answer questions, write and revise text, explain concepts, analyze uploaded files and images, help with code, and perform web searches when that feature is enabled. Some capabilities, such as image generation and advanced voice interaction, depend on the user's plan, device, and region.
ChatGPT is a general-purpose tool rather than a subject-matter authority. Its responses are generated based on patterns in training data and available context, so they should be reviewed before being used for high-stakes decisions.

ChatGPT is useful for drafting and thinking, but it can also be wrong while sounding confident. Check key facts against reliable primary sources, avoid entering confidential information you are not authorized to share, and maintain human judgment for high-risk or professional decisions.
