Speed Booster for ChatGPT – Fix Lag & Freezing in Long Chats

Stop browser freezing and lag in long ChatGPT conversations. Instantly speeds up the entire UI and reduces memory usage.

Stop ChatGPT from freezing and lagging - in one click. Speed Booster for ChatGPT makes huge conversations smooth again by rendering only a configurable number of messages at a time — no lost context, no data collection, no slowdown. If you use ChatGPT for coding, writing, research, or long discussions, you know the problem: once a chat gets long, Chrome slows to a crawl, scrolling becomes jittery, and CPU usage spikes. Speed Booster for ChatGPT solves this instantly. 🚀 What it does Makes ChatGPT fast again — even in threads with 500+ messages — by rendering only the latest set of messages at first. You can configure exactly how many messages to keep visible! Older messages are easily restored: just scroll up in your chat and press the "Load more messages" button. This keeps your full chat history accessible without the lag and without losing context. ✅ Why you’ll love it - Smooth, zero-lag typing & scrolling — even in massive threads - Lower CPU & memory usage — keeps Chrome fast and extends battery life - No lost messages — your complete history stays intact - Works automatically — install once and ChatGPT instantly feels faster 🔒 100% Privacy All trimming logic runs entirely on your device, and your chat data never leaves your device. No data collection, no tracking, no uploads, and no chat deletions — ever. 💎 Boost Your Workflow with PRO While the free version is perfect for most, you can upgrade to PRO for a small one-time fee to unlock unlimited fast chats. - No daily limits: Remove all daily usage limits on the lag-reduction engine for your longest conversations. - Quiet Mode: Work in a completely clean interface by disabling all UI hints and notifications. - Custom Thresholds: Gain full control over exactly how many messages are rendered at once to perfectly match your hardware's power. - By buying PRO, you support the development.

While I cannot fix OpenAI’s server-side issues, this extension significantly optimizes how your device handles large chats. Please note: I am a solo developer managing this project in my spare time alongside a full-time job. I do my best to keep the code updated and answer most important emails personally. I kindly ask for your patience and constructive feedback as I work to make the tool better for everyone and keep it working as long as possible. If this extension helps save you time, like it does for so many other people, please consider supporting the development by buying a PRO license - it makes a huge difference! If you run into an issue, please contact me via contact@gptspeedbooster.com before leaving a negative review. Constructive feedback helps me make the tool better for everyone! This extension is an independent project and is not affiliated with, endorsed by, or sponsored by OpenAI or ChatGPT. ============ UPDATE v2.1.5: FURTHER OPTIMIZATIONS & BUG FIXES WHAT’S NEW: Improvements to trimming logic: Significant further optimizations for long chat sessions.
