Search uploaded knowledge documents (PDFs, Word documents, Excel files, etc.) for relevant information. Generate a professional, context-aware email response using AI. Save the generated response as an email draft (do NOT send automatically). I will review the draft, make edits if necessary, and manually click Send. Knowledge Base The platform should allow me to upload and organize: PDF documents Word documents Excel files Compliance manuals SOPs Policies Guidelines Previous response templates The AI should use Retrieval-Augmented Generation (RAG) so that responses are grounded in my uploaded documents rather than relying only on general AI knowledge.
