ChatGPT is a natural language processing tool driven by AI technology that allows you to have human-like conversations and much more with a chatbot. The language model can answer questions, and assist you with tasks such as composing emails, essays, and code.
Usage is currently open to public free of charge because ChatGPT is in its research and feedback-collection phase. As of Feb. 1, there is also a paid subscription version called ChatGPT Plus.
