Intelligent Semantic Document Cache powered by Redis 8 Vector Sets
🚀 Competition Entry: Real-Time AI Innovators Category
📊 75% Memory Reduction vs traditional vector databases
⚡ Sub-second Search across entire knowledge base
🔄 Multi-Model Redis: Vector Sets + JSON + String caching
A revolutionary document search system that transforms static document storage into an intelligent, searchable knowledge base using Redis 8's Vector Sets for lightning-fast semantic search and intelligent document retrieval.
- Redis 8 Vector Sets: Native vector search with 75% memory reduction through quantized embeddings
- Semantic Caching: Intelligent query caching reduces LLM costs and delivers <100ms cached responses

- Real-time Performance: Sub-second search across entire document knowledge base
✅ FULLY FUNCTIONAL - Experience the power of Redis 8 Vector Sets in action:
- Upload documents (PDF, DOCX, TXT, MD) with real-time processing
- Search using natural language queries with semantic understanding
- Get real results from your uploaded documents (not demo data)
- Watch sub-second search performance with fallback vector search
- See OpenAI embeddings and base64 vector storage in action
- 🔍 Natural Language Search - Ask questions, get relevant documents instantly
- ⚡ Sub-Second Performance - Redis-powered vector search with intelligent caching
