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.
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.
Core capabilities we deliver as part of our rag & knowledge systems.
Ingest, chunk, embed, and index your documents for fast, accurate retrieval with any LLM.
Internal knowledge systems that let employees search across wikis, SOPs, contracts, and Slack history.
Give your customers an AI assistant that answers product questions using your documentation and help center.
Pull data from PDFs, web pages, databases, APIs, Google Drive, Notion, Confluence, and more.
Every answer includes source citations so users can verify and trust the information.
Continuously improve retrieval quality with evaluation frameworks, feedback loops, and reranking.

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.
We build production-grade AI systems — from machine learning models and LLM integrations to autonomous agents and intelligent automation. 23 AI-powered products shipped, 300+ clients served.
We build modern web applications using Next.js, React, and Node.js — from marketing sites and dashboards to full-stack SaaS platforms. Every project ships with responsive design, SEO optimization, and performance scores above 90 on Core Web Vitals.
We build native iOS, Android, and cross-platform mobile apps using Swift, Kotlin, React Native, and Flutter. From consumer apps with social features to enterprise tools with offline sync — we deliver polished, high-performance applications from concept to App Store and Play Store.
End-to-end SaaS development from MVP to scale — multi-tenancy, Stripe billing, role-based access, and cloud-native architecture. We have built and shipped 23 SaaS products of our own, serving 50,000+ users. Next.js, Node.js, PostgreSQL, AWS and Vercel.
