ChatGPT is OpenAI's general AI assistant. It can handle conversation, document summaries, image understanding and generation, voice interaction, coding help, and research inside one app, so it functions less like a narrow work tool and more like a default AI interface for daily and professional tasks. It has adoption paths for individuals, teams, enterprises, and developers.

Its strength is scale and ecosystem. OpenAI has said ChatGPT reaches more than 900 million weekly users, and the product connects custom GPTs, mobile and desktop apps, workspaces, and the developer platform under one brand. Users can start free, then move into Plus, Pro, Business, or Enterprise paths for broader model access, higher usage, and administrative controls. Korean input and output are also practical for everyday use.

The tradeoff is plan design and data operations. Newer model access, higher limits, and workplace controls are concentrated in paid plans, so the free tier can feel constrained for repeated work. Teams using company material should review workspace settings, data-use terms, permissions, and security policy before rollout. The broad surface can also feel excessive if the need is only lightweight writing.

ChatGPT is the default benchmark for users who want one app to cover many AI tasks. It is especially useful when research, writing, ideation, and coding support all matter. If cited search answers are the priority, compare Perplexity; if long-form writing and artifact collaboration matter more, compare Claude as well.
