1. Translator (95% ready)
→ Real-time streaming with <900ms latency
2. Document Analyzer (100% ready)
→ 8 document types, AI-powered structured data extraction
3. Chat with RAG (70% ready)
→ Personal context from your documents/correspondence
4. SMS Integration (100% ready)
→ Read/send SMS with AI contact analysis
📝 PLANNED (5 scenarios):
5. Multilingual Conference

```
### 2. **Personal RAG (Retrieval-Augmented Generation)**
**SmartRAG v3** - proprietary system for working with personal context:
- **Local storage** (ObjectBox + HNSW indexing) - data doesn't leave device
- **15 modules** with full embeddings, language detection, NER support
- **Persona-centric** - linking documents, SMS, email with personas (contacts)
- **On-device AI** - ONNX Runtime for generating embeddings without cloud
- **Compression** - ZSTD + int8 quantization to save space
**Advantage:** Your AI assistant knows your context, but data stays with you.
### 3. **Hybrid LLM Strategy** (Cost + Quality + Latency)
**For REAL-TIME (voice translation):**
- **PRIMARY:** DeepInfra Qwen 2.5 72B ($0.23/$0.40 per 1M tokens)
- 3.3x cheaper than competitors for high-context tasks
- Geographic proximity to Deepgram STT (US East) → ~10ms latency
- Tight coupling: Deepgram → DeepInfra → Device TTS
- **FALLBACK:** Gemini 2.0 Flash (free tier) when DeepInfra is unavailable
**For BATCH (documents, summaries, notes):**
- European providers (Germany/UK/Finland)
- Priority: quality + cost, latency not critical
**Result:** $0.20-0.50/month with active use (100 phrases/day) vs $10-30/month for competitors.
### 4. **Enterprise-grade Architecture**
- **Clean Architecture + MVI** - separation of concerns, testability
- **32 modules** with clear separation of responsibilities
- **Centralized error handling** - 17 DomainError types, type-safe errors
- **Type-safe localization** - UiString system without hardcoded strings
- **Security by design** - Voice command fuzzy logic, CAPTCHA, encrypted storage
### 5. **Openness and Extensibility**
- **Dynamic Features** - PDF/Office parsers loaded on demand (APK savings)
- **Plugin architecture** - easy to add new STT/TTS/Translation providers
- **Conductor routing** - automatic selection of best model based on latency/cost/quality
- **Future:** Scenario marketplace from community
