Challenges & Solutions
1Multi-AI Model Management
6 different AI providers had different API formats, pricing models and response structures.
Created abstraction layer with Factory pattern. Separate service class for each provider, unified management with common interface. Users can switch models seamlessly.
2Real-Time Voice Chat
Students needed to talk with AI via voice. Latency and sound quality were critical.
WebRTC + OpenAI Realtime API integration. Optimized connection management for low latency, automatic transcription and credit tracking.
3Math Formula Support
Math questions needed proper formula rendering.
KaTeX integration for LaTeX formula rendering. Automatic formula detection and conversion in AI responses.
4Dynamic Credit Calculation
Each AI model has different token pricing. Fair and transparent pricing needed for users.
Token-based cost calculation system. Automatic credit deduction based on input/output token count and model price for each API call.
Behind The Scenes
- Token count calculated for each AI response, credits deducted based on actual cost
- Voice chat has per-second credit calculation
- Homework creation with dynamic pricing based on question count (1-30 credit range)
- DALL-E image generation with different pricing by size and quality
- Bulk student import system for institutions (CSV)
- 21 database migrations for version control
- 61-page technical documentation
