## Overview

AI Mail Assistant is a small Streamlit app for turning a pasted customer email into structured guidance and a reply draft. The user submits an email; the app reads its OpenAI settings, requests analysis, displays the result, and offers a text download. The requested analysis covers category, priority, sentiment, summary, next steps, and a same-language reply. The README also emphasizes human review and that replies are not sent automatically. The graph reflects the single sampled implementation file; its capabilities are not separate modules.

Main entry points: [`app.py`](https://github.com/moseskakuno/ai-mail-assistant/blob/main/app.py) (Streamlit app)
