The best-known AI chat assistant: ask anything, get a written answer.
ChatGPT by OpenAI is a chat assistant. You type a question or task in plain language and it writes an answer: an email draft, an explanation, a plan, a list of ideas. It also works on your phone, including by voice.
For everyday writing and questions the free version is plenty.
OpenAI says the free version of ChatGPT is available to everyone. Paid plans (Go, Plus, Pro) add more messages, uploads, image creation and newer models.
