What ChatGPT Is
ChatGPT is your main thinking, writing, study, planning, and problem-solving tool inside this Command Center.
Use it to explain hard topics, organize work, write faster, debug code, and break big tasks into clean next steps.

Use ChatGPT Like an Operator
Don’t treat it like a random chatbot. Treat it like a work surface. Use a fresh chat for a new job, upload files when context matters, and pick the right model for the problem.
Use ChatGPT for school help, writing, planning, coding, research, and breaking down hard ideas fast.
Best default move
Use GPT-4o for most work. It is the best general-purpose option for reading, writing, explaining, planning, and working with files.
Clean workflow rule
New subject = new chat. That keeps context clean and makes it easier to find or reuse work later.
