Today, I’ll show you how to use ChatGPT-5 in the Cursor IDE and use it to take a messy app and make it much better. We’ll go step-by-step, from turning on GPT-5 model to using it for real coding tasks. ChatGPT-5 Cursor What is Cursor and why use ChatGPT-5 in it? Cursor is a code editor (similar to VS Code) but with AI built in. It lets you: Cursor is a code editor Chat with AI about your code Ask for code changes directly inside the editor Make multi-file edits without switching tools Chat with AI about your code Chat with AI about your code Ask for code changes directly inside the editor Ask for code changes directly inside the editor Make multi-file edits without switching tools Make multi-file edits without switching tools With ChatGPT-5 inside Cursor, you get: ChatGPT-5 Better reasoning Smarter refactoring Cleaner explanations Better reasoning Smarter refactoring Cleaner explanations How to Turn on ChatGPT-5 in Cursor Open any project and navigate to the right column with the chat.

Don’t apply changes without reading them. Ask for explanations. Use Chat to explain diffs in plain English. Work in small chunks. Big changes are harder to debug. Keep testing. Run your app after each step. Be specific. Short, clear prompts work best. Be specific Review everything. Don’t apply changes without reading them. Review everything Ask for explanations.
