ChatGPT Long Chat Optimizer

About

Long Chat Optimizer keeps long ChatGPT conversations fast from the moment they load — and responsive as you keep chatting.

Long conversations can slow down because the current ChatGPT page has to manage a lot of old messages, page state, and rendering work. Long Chat Optimizer reduces that load by keeping only your selected recent exchanges active on the current page.

Older turns are hidden from the current page and removed from the page’s local active conversation state, but they are not deleted from your saved ChatGPT conversation.

What makes it different:

• Fast initial loading for long ChatGPT conversations
• Recent messages stay responsive as you continue chatting
• No reload-only workflow — pruning can take effect while you use the chat
• More than visual hiding: reduces visible page weight and local active conversation state
• Targeted render/read caches for smoother long-chat performance
• Optional browser-native offscreen rendering optimization
• Optional scrollbars for long prompts and large code blocks
• Popup controls for recent exchanges kept and performance options

You stay in control:

Choose how many recent exchanges stay active, turn the speedup on or off, and adjust optional rendering and scrollbar settings from the popup.

Privacy:

Long Chat Optimizer runs locally in your browser. It does not collect, sell, transmit, or share your conversation data. It does not use analytics, telemetry, advertising, or tracking.

Important:

This extension affects only the currently loaded ChatGPT page. It does not delete your saved conversations and is not affiliated with OpenAI.
