ChatGPT Lightsession Chrome extension

I’ve been using ChatGPT a lot for lengthy project conversations lately. After a while the browser tab becomes unbearably slow and unresponsive — scrolling lags, typing feels delayed, and sometimes the tab just freezes entirely. The cause is the massive DOM that builds up over hundreds of messages in a single chat.

The ChatGPT Lightsession extension fixes this by removing older messages from the DOM while keeping the session intact. Simple and effective.
