How do I use ChatGPT?
To access ChatGPT, go to chat.openai.com and create a user by providing an e-mail and a phone number for verification. Currently, you can access the 3.5 version for free and the newer version for a subscription fee. After login, the ChatGPT interface looks like an internet search engine start-page, and it starts replying as soon as you hit enter after writing something. The difference is that instead of getting a long list of web pages with content related to your question, ChatGPT generates a complete answer in a format that is relevant to the question. We have included a link to a video that illustrates the process (supplement 1).
