The Multi-Model AI Chat: Your Command Center

At the heart of Sider is its AI chat panel, a central hub where you can tap into multiple cutting-edge AI models simultaneously. Unlike other platforms, Sider doesn’t lock you into one engine.

Even better, its Group AI Chat lets you pose a single query to multiple models at once and compare answers side by side.

Plus, the in-context chat understands the webpage you’re browsing, meaning you can ask questions about what you’re reading or watching without retyping anything. With Sider, your browser becomes a true AI command center.
