RAG Development — Turn Your Data into Intelligent Knowledge Systems
We build retrieval-augmented generation (RAG) systems that let your team and customers query your company's knowledge — documents, manuals, policies, code, and data — using natural language with accurate, cited answers.

ZTABS provides rag & knowledge systems — We build retrieval-augmented generation (RAG) systems that let your team and customers query your company's knowledge — documents, manuals, policies, code, and data — using natural language with accurate, cited answers. Our capabilities include custom rag pipelines, enterprise knowledge bases, customer-facing ai search, and more.
How We Approach RAG & Knowledge Systems
Large language models are powerful but they hallucinate when asked about your specific company, products, or processes. RAG solves this by grounding LLM responses in your actual data. When a user asks a question, the system first searches your documents for relevant passages, then feeds those passages to the LLM alongside the question.
The result: accurate answers with source citations, not fabricated responses. We build production RAG systems that go beyond basic vector search. Our pipelines use hybrid retrieval (combining semantic and keyword search), reranking models that prioritize the most relevant passages, query expansion that handles ambiguous questions, and agentic RAG that breaks complex queries into sub-questions and synthesizes answers from multiple sources.
We built Chatsy — our own AI chatbot platform with RAG at its core — which processes thousands of queries daily. That production experience informs every system we build. Data ingestion is where most RAG projects fail silently.
PDFs with tables, scanned documents, nested folder structures, and inconsistent formatting all require custom parsing. We build ingestion pipelines that handle messy real-world data, not just clean markdown files. Every system includes evaluation frameworks that measure retrieval precision, answer accuracy, and hallucination rates against ground-truth datasets so you can track quality and improve over time.
Common Use Cases for RAG & Knowledge Systems
- Internal knowledge base that lets employees search HR policies, SOPs, and company wikis using natural language
- Customer-facing AI assistant that answers product questions using documentation and help center articles
- Legal document search system that finds relevant clauses, precedents, and contract terms across thousands of documents
- Technical documentation assistant that helps developers find API references, code examples, and troubleshooting guides
- Medical knowledge system that surfaces clinical guidelines and research papers for healthcare providers
- Sales enablement tool that retrieves relevant case studies, pricing details, and competitive intel for sales reps
- Compliance assistant that checks policies against regulations and flags gaps in coverage
- Training and onboarding system that answers new employee questions from company handbooks and Slack history

Frequently Asked Questions About RAG & Knowledge Systems
Find answers to common questions about our rag & knowledge systems.
RAG is a technique that combines a search/retrieval system with a large language model. When a user asks a question, the system first retrieves relevant documents from your knowledge base, then feeds them to an LLM to generate an accurate, grounded answer with citations. This dramatically reduces hallucination compared to using an LLM alone.
