Lyra - AI Teacher Joins Your Calls

Lyra is your AI teacher that joins group study calls on Discord, explains concepts in voice, keeps sessions focused, and auto-generates personalized notes and takeaways after each call.

Inspiration

Lyra was inspired by my own high school study sessions — where “group studying” often turned into confusion, arguments, or distractions. We wanted to build something that keeps the collaboration but adds focus and instant help when we need it.

What It Does

Lyra is an AI study partner that joins your Discord calls. She listens to your group conversations, explains concepts in real time, answers questions in voice, and can quiz you on any topic — making group studying productive, social, and fun. We also built a companion website where students can upload notes, share topics, and sync their study progress with Lyra.

How We Built It

  • Gemini Live API for real-time reasoning and responses
  • ElevenLabs TTS for natural, engaging voice output
  • Auth0 + Supabase for authentication and data management
  • Discord API for multi-user voice and chat integration

Challenges We Faced

  • Significant latency in voice responses from Gemini Live
  • Frequent interruptions and inconsistent conversation flow
  • Debugging AI-generated “fixes” that made things worse — we learned the hard way to understand our stack before patching it

Accomplishments We’re Proud Of

  • Reduced latency to a usable and smooth experience through creative optimizations
  • Built a complete dashboard and mock integration that actually feels usable
  • Designed a system that feels authentically social, not just another chatbot

What We Learned

  • The Gemini Live API is powerful but unstable, requiring heavy handling for real-world use
  • Understanding your code matters — AI can accelerate, but not replace, comprehension
  • Human-centered design (meeting students where they already are) is key to adoption

What’s Next for Lyra

  • Further latency optimization and improved conversation flow
  • Flashcard generation and personalized review sessions
  • Integration with Instagram and other platforms students already use
  • Visual teaching mode, where Lyra can see screens or draw on a whiteboard
  • Long-term vision: a multi-modal AI teacher that collaborates like a real study buddy
