The Problem with Document Search Today
Every organization sits on mountains of data locked inside PDFs, spreadsheets, Word documents, and scanned papers. When employees need answers, they face two bad options:
1. Manual search: Open files one by one, ctrl+F through hundreds of pages, piece together insights from scattered sources. Time-consuming and error-prone.
2. Cloud AI services: Upload sensitive documents to third-party APIs. Fast answers, but at the cost of data sovereignty, compliance risk, and recurring API fees.
What if you could have the speed of AI-powered search without sending your data anywhere?
Meet Selvo Lens
Selvo Lens is an enterprise-grade Retrieval-Augmented Generation (RAG) system that runs entirely on your infrastructure. Upload documents, ask questions in natural language, and get accurate answers with source citations - all processed locally.
No external APIs. No data leaving your network. No per-query costs.
What Makes Selvo Lens Different
1. Hybrid Retrieval for Higher Accuracy
Most document search tools rely on either keyword matching (fast but misses context) or vector search (semantic but can drift). Selvo Lens combines both:
- BM25 keyword search catches exact matches and specific terms
- Vector embeddings understand meaning and context
- Cross-encoder reranking refines results for maximum relevance
The result: fewer hallucinations, more precise answers.
2. Works With Your Actual Files
Real businesses don't store everything in plain text. Selvo Lens handles the formats you actually use:
PDF - Text-based and scanned (auto-detected)
Word - docx, .doc with tables
Excel - Full spreadsheet analysis
CSV - Auto-encoding detection
Images - OCR extraction (PNG, JPG, TIFF, BMP)
Upload a scanned contract from 2015? Selvo Lens extracts the text automatically. Need to query across 50 Excel reports? Just upload and ask.
3. Truly Private by Design
Your documents never leave your network. The entire system - LLM, vector database, OCR engine - runs locally:
- Local LLM via Ollama (Qwen3)
- ChromaDB vector store on your servers
- Tesseract OCR for scanned documents
- Zero external API calls during operation
Deploy on-premise. Your data stays yours.
4. GPU-Accelerated Performance
When answers need to come fast, Selvo Lens delivers:
- 3-10x faster inference** with NVIDIA GPU acceleration
- Automatic GPU detection and optimization
- Works on CPU too (no GPU required)
Whether you're running on a developer laptop or a production server with multiple GPUs, Selvo Lens adapts.
