ChatGPT Performance Long Chats is a lightweight Chrome extension that eliminates lag and improves responsiveness in long ChatGPT conversations. As chats grow larger—especially with detailed explanations, long‑form writing, or extensive code blocks—performance often slows down due to the growing number of rendered messages in the browser. This extension optimizes how conversations are displayed to keep ChatGPT smooth and fast.
Instead of rendering the entire conversation at once, the extension automatically collapses older messages and keeps only the most recent ones visible. This significantly reduces DOM size and improves scroll performance in long chats. When you scroll upward, previously hidden messages are revealed automatically, so you never lose access to your full chat history.
You can configure how many recent messages remain visible by default, letting you balance performance and context based on your workflow. Whether you are reviewing code, writing long technical prompts, doing research, or managing extended discussions, the extension keeps ChatGPT responsive even in very large conversations.
The extension runs entirely client‑side. It does not collect data, does not track you, and does not send any information to external servers. All processing happens locally in your browser on chatgpt.com.
If you frequently experience slow scrolling, UI lag, freezing, or reduced responsiveness in long ChatGPT threads, ChatGPT Performance Long Chats provides an immediate performance boost without altering your content or deleting conversation history.

So far, does PRECISELY what I wanted an extension like this to do. The auto-reveal is such a simple but significant functionality, which I've not seen in competing extensions. I also like the minimal and non-intrusive design. Integrates very well into the overall ChatGPT UI / UX. Most importantly, I enjoy that there isn't a paywall.
That's incredible, bro, thank you so much! I already thought to create own, but first tried to Google and found your extension. It works as well. Thanks!
Amazing extension, basically no lag now. Except when ChatGPT is writing an answer it slows down a lot. Is there a solution to this? Would give 5 stars otherwise.
It simply works. Nice job.
Its basically like reverse lazy loading. Pretty neat.
