Zuo GPT Plugin

Zuo GPT Plugin is a free Chrome extension that does one small job and does it directly: it customizes the CSS of the ChatGPT web interface so the chat window becomes much wider and closer to full-screen. Many users find the stock ChatGPT layout leaves large empty margins on wide monitors, which wastes horizontal space when reading long answers or pasting wide code blocks. This extension tweaks those styles so the conversation takes up far more of the viewport.

The extension was published in the Chrome Web Store on May 15, 2024, is offered by developer Zuo Zonglin (Hangzhou, China) and is distributed at no cost. It is a very small package, roughly 23 KiB, written to work with the ChatGPT site in Chinese-language environments. It requires no account, no API key and no server-side service, because it only restyles a page you are already viewing.

Because the tool simply applies CSS to the page, it is a styling utility rather than an AI model or a chatbot of its own. It does not send your prompts anywhere else, does not store conversations and does not interact with OpenAI's API on your behalf. It also declares that it only handles website content and that data is not sold to third parties. It suits users who want a cleaner, wider ChatGPT reading and writing surface without installing a full sidebar assistant.
