ChatGPT Lag Remover

Solves the lag issue in big chats. Deletes older ChatGPT turns from the DOM. Fast prune, eager detach, and optional auto-reload

Long ChatGPT conversations can get painfully sluggish. ChatGPT Lag Remover trims older turns from the page so Chrome renders less, uses less memory, and stays responsive—without touching your server-side history. If this extension helps you, please consider supporting development (and future updates)—or just buy me a beer 🍺: What it does Keep last N messages (default 10). Auto-prune on new turns or Prune now on demand. Auto reload when an answer finishes (optional) to clear buildup while keeping the latest reply visible. Duplicate & close original: reopens the current chat in a fresh tab to reclaim memory. Preserves code blocks, edit buttons, and normal UI behavior. Why it helps Very long threads accumulate thousands of DOM nodes and style rules. Pruning older turns reduces layout/paint work and memory pressure—especially once you pass ~200 messages. Safe by design Does not delete your chat history. It only removes nodes from the current page. Refresh to see the full thread again. No data collection.
