Keep long ChatGPT conversations responsive by reducing browser rendering and memory pressure. Long conversations can overwhelm a browser with thousands of interface elements, heavy message rendering, and rising memory use. ThreadTamer keeps supported conversations responsive by limiting how much older history is rendered at once. Choose how many recent messages to keep visible, reload the page, and continue working with less browser overhead. Your complete conversation remains on the service. Turn Long Chat Mode off and reload whenever you need the full history again. ThreadTamer also includes an optional local diagnostic recorder. It measures main-thread blocking, DOM size, JavaScript heap pressure, layout shifts, and slow resources so you can understand what is slowing a page down. Reports are created only when you explicitly export them. KEY FEATURES - Reduce the amount of conversation history rendered in the browser - Choose between 10 and 100 recent messages - Restore the complete conversation at any time - Diagnose browser rendering and memory pressure - Export a local, privacy-conscious performance report - No account, advertising, analytics, or remote service PRIVACY BY DESIGN Conversation data is processed transiently on your device only to reduce rendering load. ThreadTamer does not store or transmit conversation content. Diagnostic reports are saved locally only when you choose Export. COMPATIBILITY ThreadTamer currently runs on chatgpt.com and chat.openai.com. Website updates may temporarily affect compatibility. INDEPENDENT SOFTWARE ThreadTamer is an independent browser extension. It is not affiliated with, authorized by, sponsored by, or endorsed by OpenAI. ChatGPT is a trademark of OpenAI.
