Rubber-Ducking Bugs With an AI Chatbot
Explaining your bug to an AI chatbot like ChatGPT or Claude often shows you the answer before the AI even replies.

The big idea
Rubber-ducking means explaining your bug out loud to a rubber duck on your desk. Half the time you spot the fix while talking. AI chatbots like ChatGPT or Claude are rubber ducks that talk back — and the talking-back part is a bonus, not the main event.
Some examples
- You paste a broken function into Claude and start typing 'I expected X, but I got Y'. Mid-sentence you realize you forgot a return statement.
- You describe a CSS layout that won't center to ChatGPT and notice the parent has display:inline.
- You explain a failing test to GitHub Copilot Chat and spot the typo in your assertion.
- You walk Cursor's chat through your data flow and realize you mutated the array you meant to copy.
Try it!
Next time you're stuck for more than 10 minutes, open a chat and write a paragraph explaining the bug like the AI knows nothing. Send it. See if you solved it before the reply finishes streaming.
