Chatbonsai

ChatBonsai keeps AI chatbots fast and responsive, no matter how long your conversation gets.
AI chat apps like ChatGPT, Claude, Copilot, and Gemini keep every message permanently rendered in the DOM. After a long session you can have thousands of elements sitting in memory, causing sluggish scrolling, slow responses, and a browser that feels like it's wading through mud.
ChatBonsai fixes this by virtualizing off-screen messages — trimming what your browser holds in memory while you chat, and silently restoring messages the moment you scroll back to them.
