Build me a Chrome extension called CourseChat that helps students study from their own class materials.

I want to be able to open it in the Chrome side panel, upload things like PDFs, slides, Word docs, notes, and maybe code or notebooks, then ask questions in plain English and get clear answers with citations back to the source file and page number. It should support a free Gemini API key, keep the key stored safely in the browser, and use the uploaded material to answer from the most relevant parts instead of sending everything every time.

Please make it feel polished and easy to use, with file previews, drag and drop upload, dark mode, exportable chat history, text to speech, and simple settings. If the backend is needed for the study search and answer flow, wire that up too so the app can index documents and reuse them across sessions. If you need to check current docs online for any API details, go ahead.
