Private Knowledge Assistants
AI assistants that answer questions from internal documents, policies, manuals, reports, contracts, tickets, and knowledge bases with traceable sources.
Production RAG Systems
Reliable RAG systems for private knowledge, documents, and business workflows.
We design and build retrieval-augmented generation systems that connect language models with trusted company knowledge, structured documents, semantic search, reranking, citations, evaluation, and production deployment.
Production AI engineering
From AI demos to production knowledge systems
Many RAG projects work in a demo but fail in real business use. The issue is usually not the language model alone. It is the retrieval pipeline, document structure, chunking strategy, metadata, access control, evaluation, latency, and reliability. Cognivox Labs helps teams build RAG systems that are designed for real users, real documents, and real operational constraints.
Knowledge systems
What we build
Semantic Search Systems
Search experiences that understand meaning, not only keywords, using embeddings, vector search, hybrid retrieval, filters, metadata, and ranking strategies.
Document Intelligence Workflows
Systems that extract, structure, search, summarize, compare, and explain information from PDFs, manuals, forms, reports, and other business documents.
RAG for Customer and Employee Support
Knowledge systems for support teams, onboarding, help centers, service desks, internal operations, and expert assistants.
RAG Evaluation and Optimization
Evaluation workflows for faithfulness, answer relevance, context recall, context precision, retrieval quality, latency, and cost.
Production Deployment and Monitoring
Backend APIs, secure infrastructure, logging, observability, feedback loops, usage analytics, prompt versioning, and continuous improvement.
Retrieval quality
Core RAG engineering capabilities
Knowledge Ingestion
Document parsing, cleaning, chunking, metadata enrichment, indexing, and update pipelines.
Embedding and Retrieval
Vector search, hybrid search, metadata filtering, query rewriting, multi-query retrieval, and retrieval strategy design.
Reranking
Neural reranking, cross-encoder reranking, relevance scoring, ranking optimization, and retrieval quality improvement.
Grounded Generation
Prompt design, context assembly, citation-aware answers, source attribution, refusal behavior, and hallucination reduction.
Evaluation
RAG quality evaluation using faithfulness, answer relevance, context recall, context precision, retrieval accuracy, and human review.
Security and Access Control
Private knowledge access, role-based permissions, tenant-aware retrieval, secure APIs, and data isolation.
Good fit
When this service is a good fit
- You have valuable company knowledge locked inside PDFs, manuals, reports, policies, or internal tools.
- You need an AI assistant that gives grounded answers with citations and source visibility.
- Your current chatbot gives generic answers and cannot reliably use your private knowledge.
- You want better search across technical documents, customer support content, research material, or business knowledge.
- You need to evaluate RAG quality instead of relying only on subjective demos.
- You want to move from an AI prototype to a production-ready knowledge system.
Process
How we build production RAG systems
- 01
Knowledge and use case discovery
We identify the target users, documents, workflows, answer types, risks, and success criteria.
- 02
Data preparation and ingestion
We prepare documents for retrieval through parsing, cleaning, chunking, metadata design, and indexing.
- 03
Retrieval architecture
We design the retrieval pipeline using embeddings, vector search, hybrid search, filters, query expansion, and reranking where needed.
- 04
Grounded answer generation
We connect retrieval results to language models with citation-aware prompting, source handling, response rules, and fallback behavior.
- 05
Evaluation and optimization
We measure retrieval quality, answer relevance, faithfulness, context precision, context recall, latency, and cost.
- 06
Deployment and improvement
We deploy the system with APIs, monitoring, logs, feedback loops, admin tools, and iteration cycles.
Engineering notes
