ChatGPT

ChatGPT is a conversational artificial intelligence application developed by OpenAI, designed to help individuals and teams solve everyday and professional tasks through a simple, fast, and increasingly multimodal chat interface. It enables writing, summarizing, researching, analyzing information, generating ideas, coding, and working with different content types from a single place. ChatGPT is available on the web, iOS, Android, and as a desktop app for macOS and Windows. A key differentiator is that it is not limited to text — depending on the plan, it can work with real-time web search, file uploads, data analysis, image generation, voice, and in higher tiers, deep research, tasks, projects, custom GPTs, and agents. The freemium model offers a free version with limited access to relevant capabilities, plus paid plans (Plus, Pro, Business, Enterprise) for different usage levels. For individual users, ChatGPT is especially useful for writing, editing, summarizing information, ideation, learning, and resolving complex questions. For teams and businesses, it adds value in productivity, research, document analysis, content generation, and knowledge work.
