Long AI chats make your browser crawl. ThreadLite keeps them usable.
When a project chat gets heavy, ThreadLite keeps recent messages active first and moves older chat UI out of the browser's working load. No chat upload, no screenshots, no analytics.

The demo is the proof point: a heavy AI chat stays easier to use when ThreadLite keeps the browser focused on the messages you are working with now.

Long chats can slow down because the browser is still carrying a lot of old message UI. ThreadLite reduces that load by keeping recent messages active first and loading older batches only when you need them.
Built for the chat pages where long work piles up.
ChatGPT is the primary tested surface. ThreadLite also includes selected support for Claude, Gemini, Perplexity, Copilot, and Grok, with conservative behavior for each chat page.
