About

This Chrome extension applies a small CSS modification to enable full-screen chats in ChatGPT, improving readability and focus. It has no scripts, no tracking, and no data collection—just a simple style adjustment. The footprint is minimal, ensuring no impact on performance or security.

Using Extension:
Activate the extension by starting a chat (asking ChatGTP a question) and then refreshing the page after the response has completed.
