ChatGPT History Cleaner – Fix Lag & Speed Up Long Chats
🚀 Is ChatGPT getting slow in long conversations?
If you experience laggy scrolling, slow typing, or freezing when chats get too long (50+ rounds), this extension is for you.
ChatGPT History Cleaner helps you instantly speed up ChatGPT by keeping only recent conversation rounds visible — making the page fast, smooth, and responsive again.
