Sider AI is a browser sidebar assistant that integrates top AI models like GPT‑4, Claude, Gemini, and more. What makes it special is its all-in-one setup—chat, writing, summarizing web pages or PDFs, translating, researching, and even image generation—all without leaving your browser. It’s best for researchers, writers, and professionals who want AI power right where they work.

✅ It works smoothly: open the sidebar, pick a model, and ask anything—from drafting essays to extracting key points from a YouTube video or PDF.

❌ But because it crams so many features into one tool, the interface can feel a bit overwhelming, and mastering each function takes time.

Still, for anyone seeking multi-modal AI help in one handy place, Sider is a productivity game-changer.
