Hide ChatGPT Sidebar

Hide ChatGPT Sidebar addresses a simple but persistent complaint about the ChatGPT web interface: the conversation history column takes up screen real estate whether or not you are using it. This extension hides that sidebar automatically as soon as the page loads, so the chat takes the full width and nothing competes with the answer you are reading.

The behaviour is intentionally unobtrusive. Clicking the extension icon toggles the sidebar back whenever you want to browse past conversations, so nothing is lost, just moved out of sight. For ChatGPT Plus subscribers it also selects the GPT-4 model on load, saving a manual step each session. It is built to stay light, with automatic updates and a privacy stance that avoids unnecessary permissions, interacting only with the ChatGPT site.

This is a small quality-of-life tweak rather than a productivity suite. It has built a genuinely useful install base and a Featured badge on the Chrome Web Store, and its narrow scope is the point: it does one thing and does it without adding friction or asking for data it does not need.
