SmartChat - for ChatGPT

Speeds up ChatGPT rendering and page loads. Full conversation history with on-demand loading and real-time performance stats.

SmartChat supercharges your ChatGPT experience. Long conversations on ChatGPT get painfully slow — pages freeze, scrolling stutters, and switching between chats takes forever. SmartChat fixes all of that. How it works SmartChat intercepts how ChatGPT loads conversations and applies smart rendering: only the messages you actually see are rendered in the DOM. As you scroll, older messages are loaded on demand from a local cache. The result? Conversations with hundreds of messages load just as fast as brand new ones. Key features • Instant page loads — conversations render up to 50% faster, even with 500+ messages • Full conversation history — scroll up to access every message, loaded on demand as you need it • Searchable history — find past messages without waiting for the entire conversation to load • Image support — generated images and uploaded files are preserved in history • Real-time performance HUD — see exactly how much time SmartChat saves on every page load • Fully configurable — adjust how many messages to keep visible, rendering batch size, and more Privacy first SmartChat never sends your conversation data anywhere. Everything stays in your browser. Cached conversations are automatically purged every 4 hours, when you close the tab, and are limited to 5 conversations at a time. The only network call SmartChat makes is for license validation — zero tracking, zero analytics, zero third-party dependencies.
