ChatGPT

ChatGPT is a general-purpose AI assistant from OpenAI that runs in a web browser, as a desktop app, and on iOS and Android. You describe what you need in plain language, and it answers with text, images, files, or working code. The free plan covers everyday chatting, while paid tiers add stronger reasoning models, longer memory, deeper research, and higher usage limits. Teams can move into a shared workspace with company context and admin tools.

Key Features

• Conversational assistant with unlimited text chats on every plan, including the free tier.
• Deep research that works through a topic and returns a longer write-up.
• Image creation and editing inside the same conversation thread.
• Voice conversations for hands-free back-and-forth.
• Memory and context that carry preferences and earlier details into new chats.
• Codex, a coding mode that works across a codebase to implement features, fix bugs, and return reviewed changes.
• Plugins, custom GPTs, scheduled tasks, and Projects that turn repeated prompts into reusable workflows.
