How to Use ChatGPT for Code Review (with Prompts)

Can ChatGPT actually review code? ChatGPT can review code. If you paste a function, a class, or even a few hundred lines of source code into the chat window and ask it to find bugs, it will often identify real issues. It can spot null reference errors, missing error handling, SQL injection vulnerabilities, race conditions, and inefficient algorithms. For a general-purpose language model that was not specifically designed for code review, its ability to catch real problems is genuinely impressive. But "can it review code" and "should you rely on it for code review" are two different questions, and the answer to the second one depends entirely on what you expect from it. What ChatGPT does well ChatGPT excels at reviewing isolated code snippets. When you give it a single function or a small module with clear boundaries, it can provide surprisingly thorough feedback. Here is what it handles reliably: Bug detection in contained logic - Off-by-one errors, incorrect boolean conditions, missin
