File Uploads in AI

Could you enable file uploads to Leo, if not already available? This would include documents, pictures, etc., allowing Leo to interact with them. For instance, uploading a picture of a toaster to search Brave for where to buy one, or uploading Microsoft Word, Excel, and PowerPoint files for interaction. I know Brave can open PDFs and the AI can interact with them, but this request is mainly for Word, Excel, and PowerPoint files.
