Overview
ChatGPT is OpenAI's flagship conversational AI assistant that launched in November 2022 and became the fastest-growing consumer application in history. In 2026, it has evolved into a comprehensive AI platform that can read documents, browse the web, generate images (via GPT-4o native image generation), transcribe and synthesize speech, run Python code in a sandbox, remember things across conversations, group related work into Projects, schedule tasks, and host user-built Custom GPTs. With over 1 billion monthly active users and 900 million weekly active users, ChatGPT dominates the generative AI chatbot market with approximately 77% of the AI search market share.
