SpeedGPT — Lag Fix & Speed for ChatGPT

Speed up long ChatGPT conversations by hiding older messages, reducing lag and keeping every chat smooth and responsive.

Long ChatGPT conversations can become slow, laggy, or unresponsive as more messages accumulate. SpeedGPT reduces the unnecessary load created by older messages, helping long conversations remain smooth, fast, and responsive. SpeedGPT keeps the newest part of your conversation visible while temporarily hiding older messages. This reduces the amount of content your browser needs to process and render at once. Your messages are never deleted or modified, and you can bring older content back whenever you need it. KEY FEATURES • Automatic performance boost Open a supported conversation and SpeedGPT automatically detects the chat and applies its performance optimization. • Adjustable message limit Choose how many recent messages remain visible, from 1 to 200. A lower limit can provide a lighter page, especially in extremely long conversations. • Load older messages without refreshing Use “Show 5 older messages” to reveal previous content gradually without refreshing or reloading the conversation. • Restore everything with one click The “Show all” option makes every hidden message visible again. No conversations or messages are deleted. • Real-time performance panel See how many messages are visible or hidden, which optimization mode is active, and the estimated amount of conversation data skipped during processing. • Persistent performance history Track today’s boosts, total optimizations, hidden messages, and skipped data from the built-in history screen. • Network and DOM optimization Whenever possible, SpeedGPT reduces older conversation data before it is processed. A page-level DOM optimization method is available as a fallback when needed. • English and Turkish interface The extension interface is available in English and Turkish based on your browser language. HOW DOES IT WORK? SpeedGPT keeps the most recent part of the conversation on screen and temporarily hides older sections. This approach helps reduce browser processing and rendering load, especially in chats containing hundreds or thousands of messages. YOU STAY IN CONTROL Enable or pause Performance Mode whenever you want. Change the visible message limit, reveal older messages five at a time, or restore the entire conversation with a single click. PRIVACY SpeedGPT does not store the contents of your messages in its performance history. Only technical performance metrics—such as message counts, optimization time, and skipped data—are recorded. Google sign-in provides secure, passwordless account access. SpeedGPT never asks for your ChatGPT or Google password. If slow pages, input lag, delayed scrolling, or freezing make long AI conversations difficult to use, SpeedGPT provides a lighter and more responsive chat experience. SpeedGPT is an independent browser extension and is not developed, endorsed, or sponsored by OpenAI.
