🎯 What It Does

PosturePal analyzes a user's posture using their webcam and provides instant feedback. It detects key body landmarks, calculates posture metrics, and assigns a score based on alignment.

🚀 Features:

• Detects and evaluates posture in real-time using machine learning.
• Generates summaries and personalized improvement strategies using AWS Bedrock and Mistral AI (Mistral Large 24.02).
• Tracks posture history with visualizations for long-term insights.
