ChatGPT
ChatGPT is a conversational AI system developed by OpenAI based on GPT models, available via web interface, mobile app, and API. It powers web search and answer synthesis features.
Definition
ChatGPT uses OpenAI's GPT models to engage in multi-turn conversations, answer questions, and generate content. The system was trained on data up to April 2024 and can access current web search through integration with Bing when the web search feature is enabled. ChatGPT supports both text and image inputs.
ChatGPT's conversational interface and search capabilities make it one of the most-used AI systems for answer generation. Its adoption influences search behavior, citation patterns, and user expectations for AI-powered answers. ChatGPT's success accelerated broader adoption of generative answer engines.
Why it matters for AI visibility
ChatGPT's search feature surfaces your brand to millions of users daily as part of synthesized answers. Your content visibility depends on being indexed by Bing and retrievable within ChatGPT's context window. ChatGPT's market dominance makes it a primary target for AI search visibility optimization.
