After installing and signing in, a Sider AI icon appeared at the bottom right of my screen. Once I clicked on it, a sidebar with a chat interface opened. From there, I could select a specific AI model from the "Sider Fusion" menu.

During daily use, Sider AI became a practical companion for my routine tasks. It automatically understands the context of the webpage you're viewing. As a result, I only needed to choose an action from the sidebar to work with it. For example, selecting "Summarize" instantly generates a concise summary of the page content.
