Content last verified May 4, 2026 · by the AI Tools Set Research Team

ChatGPT is OpenAI's conversational AI, widely used to brainstorm essay topics, create outlines, draft and revise text, and explain concepts. It can adopt an academic tone, structure arguments, and help you improve your own writing through dialogue.

As a general-purpose assistant, it is one of the most popular tools for essay help, best used to support your thinking and revision rather than to submit generated work.
