Key User Benefits:

1. Personalized Interaction
   Choose from four distinct personalities (Friendly, Professional, Humorous, Wise) that shape your companion’s responses to match your mood and needs.

2. Emotional Support
   The friendly and wise personalities offer compassionate listening and thoughtful responses, providing comfort during stressful times.

3. Adaptive Learning
   While this demo version uses predefined responses, a full implementation would remember user preferences and conversation history for increasingly personalized interactions.
