ChatGPT is a conversational AI platform built by OpenAI that uses the GPT model family to handle a broad range of tasks through natural language input. Users can ask questions, request written content, generate and debug code, analyze uploaded files and images, perform web searches with citations, create AI images via DALL-E, and interact through voice mode. The interface supports custom GPTs — specialized agents configured for particular domains or workflows — and a ChatGPT agent mode for multi-step task execution that can operate across documents, tools, and data sources. ChatGPT is used across virtually every professional and personal context where AI assistance is applicable. Students use it for writing support and concept explanation.
