GlueGPT — Pin Sidebar is a Chrome add-on designed to enhance the user experience on ChatGPT and Gemini by keeping the sidebar permanently open. With a simple one-click pin feature, users can easily lock the sidebar in place, preventing it from collapsing during use. This functionality is particularly useful for those who frequently switch between tabs or need constant access to sidebar tools while engaging with content.

The add-on ensures a persistent pinned state that is saved across page loads, providing a seamless experience. It supports tab synchronization, meaning that if the sidebar is pinned in one tab, all other tabs will reflect this change. GlueGPT also features smart reopening capabilities for Gemini, preserving the content rendering, and allows for independent management of pinning settings via the toolbar popup.
