ChatGPT Speed Booster

Stop ChatGPT from Freezing and Lagging in One Click

Speed Booster for ChatGPT is the Chrome extension to fix ChatGPT lag, freezing, slow scrolling, and high CPU usage in long conversations on Windows, Mac, and Chromebook.

If you use ChatGPT for coding, writing, research, or long discussions, you already know the problem. After dozens of messages, Chrome slows to a crawl, scrolling becomes jittery, CPU usage spikes, and the tab starts freezing. Speed Booster for ChatGPT fixes that instantly, automatically, and privately.

How It Fixes ChatGPT Lag and Freezing

ChatGPT loads every single message into your browser at once. In long chats, Chrome has to render thousands of elements simultaneously, which tanks performance. Speed Booster manages rendering intelligently so only the messages visible on screen are active at any time. The result is smooth typing, smooth scrolling, and far lower CPU load even in chats with 500 or more messages.

What It Does

Lazy Load History loads older messages on demand as you scroll up. Your full chat history stays completely intact without any lag.

Performance Mode strips unnecessary DOM elements, disables heavy animations, and reduces rendering overhead for maximum speed.

Fast Scroll uses optimized scroll handling that eliminates jitter and stuttering in long conversations.

Density Modes let you choose between Default, Compact, or Ultra-Compact layouts to fit more content on screen.

Strip Code Colors removes syntax highlighting by default to reduce rendering weight. You can re-enable it from settings anytime.

Disable Animations kills all CSS animations and transitions for a snappier, faster interface and is enabled by default.

Disable Avatars hides avatar images and collapses their column to reclaim horizontal space and is enabled by default.

Optimization Profiles let you switch between Balanced, Max Speed, Reading, and Dev Mode presets that automatically configure all settings for your workflow.

Search in Conversation lets you instantly find any text in the current chat with highlighted results and keyboard navigation using Ctrl Shift F.

Conversation Map uses auto-detected topic sections so you can jump between different parts of a long conversation using Ctrl Shift M.

Export Conversations lets you download your chats as Markdown, Plain Text, or print to PDF.

Advanced Settings give you full control over DOM limits, observer timing, scroll debounce, lazy load buffer, and rendering options.

Quiet Mode disables all notifications for a completely clean interface.

Why You Will Love It

Smooth zero-lag typing and scrolling even in massive threads with hundreds of messages. Lower CPU and memory usage keeps Chrome fast and extends battery life. No lost messages because your complete history stays intact at all times. Works automatically so you just install once and ChatGPT instantly feels faster. Every feature is fully configurable right from the popup. No account required to use the extension.

100% Private

All optimization logic runs entirely on your device. Your chat data never leaves your browser. No data collection, no tracking, no uploads, and no chat deletions ever.

A Note from the Developer

This extension is built specifically to eliminate browser-side rendering lag, which are local slowdowns caused by large DOM trees in long ChatGPT conversations. It cannot fix OpenAI server outages or response delays, but it dramatically improves how your device handles large chats. If you run into any issue, please reach out at [email protected] before leaving a review. I respond to every message and use your feedback to improve the extension for everyone.
