🛠 Technical Architecture

Audiobook Pipeline

PDF/DOCX → Text Extraction → Unicode Cleaning → 
Gemini Enhancement → Edge TTS → Audio Output

RAG Pipeline

Documents → Text Extraction → Chunking → 
Embeddings → ChromaDB → Query → Gemini → Answer

Unicode Handling

All Text → Unicode Cleaning → Safe Processing → 
Console Output → File Operations

🎯 Key Achievements

  1. ✅ Gemini-Only Configuration: Removed LM Studio dependency
  2. ✅ Unicode Error Resolution: Comprehensive fix across all components
  3. ✅ RAG System Integration: Full Q&A with document indexing
  4. ✅ High-Quality Audio: Edge TTS with multiple voice styles
  5. ✅ Robust Testing: 7/7 tests passing with comprehensive coverage
  6. ✅ Production Ready: Error handling, caching, and optimization
