What is ChatGPT?

ChatGPT is a conversational AI assistant launched by OpenAI, officially positioned as "chatting, working, creating, and coding with AI", covering daily scenarios such as question and answer, writing, image generation, and programming. It offers a web version, desktop application, and mobile version, and has both free and paid usage options. The official page emphasizes "getting tailored responses for you": after logging in, responses can combine saved chat history, and users can also create images and upload files, turning historical conversations and materials into the context of responses. It is currently one of the world's largest general-purpose AI assistants. Whether for work, study, or creation, users can start from the same dialog box and use it without additional learning, as the way of asking questions is consistent with daily chatting. The homepage after logging in also provides a starting guide of "What do you want to do?" and displays popular searches, helping new users quickly find suitable ways to use it.

Who is it for?

Individual users who use AI as a daily general assistant, as well as creators and teams that require comprehensive capabilities such as writing, programming, and data processing. The free version can cover most lightweight needs, while heavy users can upgrade as needed; in team scenarios, it can also serve as a unified writing and information processing assistant to reduce redundant work. For beginners who have never used AI before, the guided homepage and a questioning method consistent with daily chats make it almost zero learning cost.

How to use ChatGPT

You get the fastest results by starting with scenarios like writing, summarization and brainstorming.
In daily use, you can first build your proficiency by asking questions and rephrasing, then gradually try image generation and in-depth research.
The more specific your task descriptions are and the clearer the examples you provide, the higher the quality of the answers will usually be.
When dealing with important facts or code, treat the AI output as a draft rather than a final draft, and verify the key conclusions by yourself.
For team use, follow the norms of account and data management to avoid sensitive information from entering the conversation.

Things to know
