ChatGPT

ChatGPT is OpenAI's flagship conversational assistant, built on the GPT family of large language models. It can draft and edit text, explain complex topics, write and debug code, analyze uploaded files, and hold long multi-turn conversations with context.

Beyond plain chat, it supports custom GPTs, web browsing, image understanding, voice conversations, and data analysis with charts. Teams use it as a general-purpose thinking partner across research, support, and content workflows.

The free tier covers casual use, while Plus, Team, and Enterprise plans unlock the strongest models, higher limits, and admin controls. Its ecosystem of integrations and a mature API make it the default starting point for most people exploring AI.
