What it is
ChatGPT is OpenAI’s conversational AI assistant and the product that brought large language models to the mainstream. It is no longer just a chat box: web search, image generation, a code interpreter, deep research and scheduled tasks all live in one interface, backed by a large ecosystem of custom GPTs.
Who it is for
Almost everyone. The free tier covers everyday Q&A and writing; heavy users should consider Plus for deep research and higher limits; developers can integrate through the API with the most complete documentation around.
How to use
Open the website or app and start chatting. Turn on web search for fresh information, upload files for data analysis, and use Canvas to draft and edit documents side by side. Enable memory in settings so it learns your preferences over time.
Pricing
The free tier includes the flagship model with caps. Plus is a monthly subscription unlocking deep research, higher limits and early access to new features. API usage is billed separately per token.
FAQ
Free vs paid? Mainly usage limits and premium features such as deep research and early model access.
Are my chats used for training? You can opt out in settings so your conversations are not used to improve the models.
