Nilo AI: Human-like AI Avatar Platform 🤖🌐

🚀 Inspiration

We were inspired by the lack of human-like, real-time, and multilingual interactions in sectors like healthcare, HR, and customer service. Current bots felt robotic and detached — we wanted to build an emotionally intelligent AI avatar that speaks, listens, understands, and acts like a real human.

“What if support felt like a conversation, not a command?”

💡 What it does

Nilo AI delivers:

  • Real-time, voice and text-based interactions
  • Multilingual responses with lip-syncing avatars
  • API task execution
  • Emotion-aware, context-sensitive replies

It's a plug-and-play AI avatar for any industry.

🏗️ How we built it

Frontend:

  • React JS
  • JS-based lip animation with visemes

Backend:

  • Node.js for API execution
  • Google Gemini API for text generation
  • Web Speech API & Microsoft Speech SDK for voice

Graphics:

  • Avatar modeling with Photoshop, Canva, Ezgif, Viseme tools

AI Stack Table:

Feature Tool/Model Used
Text Generation gemini-2.0-flash
TTS Lip Sync Google Translate TTS + Visemes
Emotion Detection Custom Engine (JS-based)
