How it works
Less to render.
More room to work.
Long ChatGPT threads can leave the browser rendering a large conversation at once. The extension reduces that work while preserving access to your loaded history.
Reveals older messages on scroll
Keeps only your latest loaded messages visible, then reveals older ones step by step when you scroll toward the top.
Show more
Collapses long prompts
Long user messages are shortened automatically with a Show more control, keeping oversized prompts from dominating the page.
Local by design
Conversations stay yours.
The extension runs on chatgpt.com and processes conversation rendering locally. It does not collect your data, track you, or send your conversations to an external server.
No account required No external server No tracking
