Make long ChatGPT threads fast and predictable.
ChatGPT Optimizer keeps the interface snappy by reducing live DOM size and loading older messages in fixed batches. The result: smoother scrolling, fewer layout spikes, and lower memory use on big conversations.
Why it’s faster
DOM windowing: keep ~50 recent messages in the DOM; older nodes are hidden to reduce style and layout work.
Batch lazy-load: reveal older messages in fixed steps (e.g., 25 at a time) for bounded, predictable work.
Observer orchestration: MutationObserver (subtree) keeps counts accurate; optional IntersectionObserver loads one batch per distinct scroll—no cascade.

Store average score: 4.7. The bars below are calculated from synced review text only, so they may be empty for extensions that have public ratings but no synced comments yet.
