ChatGPT is a conversational AI product built around OpenAI’s family of large language models. Users interact with the system through chat-style conversations where the model can answer questions, draft and edit text, brainstorm ideas, summarize content, translate, and assist with coding and data analysis. The product continuously expands its capabilities (for example adding image and voice inputs, code editing, shopping research, and multimodal understanding) so it can handle text, audio, and images in many workflows.

Key features include an easy-to-use chat interface across web and mobile, memory and personalization settings, tools for uploading and analyzing files, built-in code editing and data analysis utilities, and the ability to create and use custom GPTs (user-configured assistants). ChatGPT also integrates features such as voice conversations, image generation and interpretation, a projects/tasks workspace, and search/real-time web access in supported modes. Business and enterprise offerings add team and admin features, enhanced security controls, data residency options, and higher usage limits.

Common use cases span productivity and creativity (drafting email, reports, and marketing copy), research and knowledge work (summarization, literature synthesis, and data exploration), software development (code generation, debugging, and documentation), learning and tutoring, and customer support or internal knowledge assistants. Audiences range from individual consumers and students to professionals, developers, startups, and large enterprises seeking to embed conversational AI into workflows or to accelerate content and software tasks.

ChatGPT’s commercial model separates its consumer-facing app from the OpenAI API: the web/mobile ChatGPT product provides interactive features, subscriptions, and collaboration tooling, while the API lets developers integrate models into their own applications and products. OpenAI maintains content and usage policies, privacy controls, and paid plans that increase performance, access to advanced models, and enterprise-grade controls for security and compliance.
