Course Generation Logic
The AI doesn't just generate random text - it follows a structured approach:
- Topic Analysis: Understanding the subject matter and complexity
- Learning Path Creation: Building a logical progression of concepts
- Content Generation: Creating detailed explanations with examples
- Assessment Integration: Including questions to reinforce learning
Memory and Performance Optimization
Running AI in the browser requires careful resource management:
- Lazy Loading: Only load the AI model when needed
- Memory Cleanup: Proper garbage collection after course generation
- Progressive Enhancement: Graceful degradation for less powerful devices
Challenges and Solutions
Challenge 1: Model Size vs. Quality
Problem: Larger models produce better content but are slower to load and run.
Solution: I implemented model quantization and compression techniques, reducing the model size by 70% while maintaining 95% of the content quality. I also added progressive loading so users see immediate feedback.
Challenge 2: Consistent Course Structure
Problem: AI can be unpredictable in output format and structure.
Solution: I developed a sophisticated prompt engineering system with strict formatting guidelines and post-processing validation to ensure every generated course follows a consistent, learnable structure.
Challenge 3: Browser Compatibility
Problem: Different browsers have varying support for AI/ML operations.
Solution: I built a feature detection system that automatically chooses the best available method (WebGPU, WebAssembly, or fallback) for each user's browser and device capabilities.
Challenge 4: Content Quality Control
Problem: Ensuring AI-generated educational content is accurate and helpful.
Solution: I implemented multiple validation layers:
- Content structure verification
- Fact-checking prompts within the AI pipeline
