Cleaning the Chat When Claude or ChatGPT Gets Confused
When Claude or ChatGPT starts repeating bad answers, start a fresh chat — the context window is poisoned.
7 min · Reviewed 2026
The big idea
AI chats remember everything in the current conversation. That's great — until you've gone in circles for 10 messages and the AI keeps suggesting the same wrong fix. Once a chat goes off the rails, it's faster to start a new one than to argue your way out. This is called context poisoning, and the cure is free: ⌘N.
Some examples
Claude keeps suggesting `useState` when you need `useReducer` — you start fresh and it gets it first try.
ChatGPT keeps including a deprecated import you mentioned 20 messages ago — new chat, problem gone.
Cursor's chat insists on TypeScript syntax in your JS file because of an earlier confusion — clear and restart.
Copilot Chat keeps referencing a function you renamed — fresh thread, real progress in 30 seconds.
Try it!
Next time you're three replies deep and the AI is still wrong, hit new chat. Paste only the current code and current question. Notice the speed.
