The Idea

What if AI could actually feel what you're feeling —

not just read your words?

That was the spark behind EmpathIQ. Built solo in 24

hours for the Replit 10 Buildathon.

What It Does

EmpathIQ combines:

👁️ Facial emotion detection via webcam

🎙️ Vocal emotion analysis via Hume EVI

🤖 Claude API responses calibrated to both signals

The result? An AI that responds to how you actually

feel — not just what you type.

The Feature That Surprised Me Most

Smart Glasses mode 🥽

Point the camera at someone ELSE. EmpathIQ reads

THEIR emotion and gives YOU real-time coaching

on what to say.

Angry person in front of you?

→ "Lower your voice and acknowledge their concern

without arguing"

The future vision is Meta Ray-Ban integration —

real-time emotional coaching in every room you

walk into.
