Also: How to use ChatGPT
ChatGPT is a conversational AI chatbot by OpenAI that can produce text for you based on any prompt you input, generating emails, essays, poems, raps, grocery lists, letters, and much more.
ChatGPT was released last November and because of its massive success, it became the blueprint for many of chatbots to enter the scene, including Bing Chat.

In addition to writing for you, ChatGPT can chat with you about simple or complex topics such as "What are colors?" or "What is the meaning of life?" ChatGPT is also proficient in STEM and can write and debug code, and even solve complex math equations. The best part is that the service is completely free to the public right now because it is still in its research and feedback-collection phase.
The big downside is that the chatbot is sometimes at capacity due to its immense popularity. However, ChatGPT Plus gives users general access even during peak times when the free version is at capacity.

Another major perk of ChatGPT Plus is that it gives users access to GPT-4, OpenAI's most advanced language model, access to the internet and citations on answers -- all features Bing Chat has for free. However, the subscription cost for ChatGPT Plus is $20 per month.
