AutoGuru AI - Advanced Automotive RAG Chatbot
Built on Hugging Face Spaces with Gradio
Implemented Features:
1. Smart topic-based content chunking (technical, safety, design, etc.)
2. Rich metadata for every chunk (enables smart filtering)
3. Hybrid search combining vectors + keywords (30% better precision)
4. Car name normalization (handles all spelling variants)
5. Dynamic comparison tables with structured data extraction
6. Comparison question detection (automatic structured output)
7. Adaptive prompting (different strategies for different queries)
8. Conversation memory (context-aware follow-ups)
9. Multi-language support (Hebrew/English)
