GPT Cleaner

ChatGPT can start lagging in long conversations, especially when many messages are loaded in the UI. GPT Cleaner solves this problem by keeping your ChatGPT interface fast and responsive. Important: This extension does NOT delete your conversations. Messages are only removed from the user interface (UI) to improve performance. Your full conversation remains safely stored in your ChatGPT account. Key features: • Fixes ChatGPT lagging in long conversations • Manually clean messages with a single click • Automatically clean messages as new replies appear • Choose how many recent messages to keep • Works only on chatgpt.com • No data collection, no tracking, no analytics How it works: GPT Cleaner removes older messages only from the page display.
