About EVII

Inspiration

The inspiration for EVII came from observing a growing disconnect in our digital age: while we're more connected than ever, genuine emotional support remains surprisingly inaccessible. We noticed that:

  • Traditional therapy is often expensive and hard to access
  • People need emotional support at unpredictable times
  • Many feel uncomfortable sharing feelings with others
  • Current AI solutions lack emotional intelligence

We wanted to create something that could bridge this gap – an AI companion that doesn't just chat, but truly understands and responds to emotional nuances.

What it does

EVII is an emotional intelligence interface that:

  • Analyzes voice emotions in real-time using Hume AI
  • Displays emotional patterns through elegant visualizations
  • Provides a responsive 3D avatar for natural interaction
  • Offers a safe space for emotional expression
  • Maintains conversation history for emotional journey tracking
  • Adapts to user preferences with dark/light mode

How we built it

We built EVII using a modern tech stack:

  1. Frontend:

    • Next.js 14 for the core application

    • Spline for 3D avatar visualization

  2. AI Integration:

    • Hume AI for emotion recognition
    • Voice analysis for real-time feedback
    • Custom emotion visualization algorithms

  3. User Experience:
