Be accurate and cite specific verses.

Context:

- [ ] Build semantic search
- [ ] Create caching layer

### Phase 2: Features (Week 3-4)
- [ ] Smart suggestions engine
- [ ] Question generator
- [ ] Thematic analysis
- [ ] RAG chatbot

### Phase 3: Optimization (Week 5-6)
- [ ] Performance tuning
- [ ] Cost optimization
- [ ] A/B testing
- [ ] User feedback loop

---

## 💰 Cost Considerations

### OpenAI Pricing (estimated)
- GPT-4: $0.03/1K input tokens, $0.06/1K output
- GPT-3.5-turbo: $0.0005/1K tokens
- Embeddings: $0.0001/1K tokens

### Monthly estimates for 10,000 active users:
- Embeddings (one-time): ~$50
- Suggestions (10/user/month): ~$150
- Semantic search (50/user/month): ~$25
- Questions (5/user/month): ~$200
- **Total**: ~$425/month

### Cost Optimization:
- Cache all responses (reduce by 60%)
- Use GPT-3.5 where possible
- Rate limiting per user
- Consider self-hosted Ollama for basic tasks
