Overview
ChatGPT is OpenAI's flagship conversational AI and a widely used AI tool in the world. Built on GPT-5.5, OpenAI's stable flagship model, it handles an enormous range of tasks with consistent reliability: content drafts across almost any format, research summaries, coding in all major languages, data analysis directly within the chat window, and real-time web search. The custom instructions feature lets you define your role, tone, and working style once, the model applies those preferences across every conversation.
The free tier provides access to GPT-5.5 with usage limits, making it the most accessible frontier AI available at no cost. ChatGPT Plus at $20/month removes rate limits, adds ChatGPT Images 2.0 for image generation, advanced data analysis with file uploads, and access to a growing library of custom GPTs and third-party integrations. For teams, ChatGPT Enterprise adds SSO, expanded context windows, and administrative controls.
Its defining strength is versatility: no single AI tool handles as wide a range of everyday knowledge work tasks as reliably, which makes it the natural starting point for anyone building an AI-assisted workflow for the first time.
