RAG Systems & Knowledge Bases
AI reads your documents and answers questions based on your data — not public internet data. For internal search, customer support, and document analysis. Price: €2,000–15,000.
What is a RAG system?
RAG (Retrieval-Augmented Generation) is an AI architecture that combines two components: document retrieval and text generation.
You ask a question → the system finds relevant sections in your documents → AI generates a precise answer based only on your data. Result: AI "knows" your internal policies, product information, and processes — and does not hallucinate.
Your documents
PDF, Word, Excel, Notion, Confluence, website content
Indexing
Text is chunked and converted into vector format (embeddings)
AI answers
Questions → precise answers drawn from your data
Most popular use cases
Internal employee knowledge base
Employees ask AI about internal policies, procedures, and instructions and get instant, accurate answers.
Customer support AI
Chatbot that answers customer questions based on your exact product descriptions and FAQ documents.
Legal document analysis
AI analyses contracts, identifies key clauses, compares documents, and drafts summaries.
Technical documentation
Engineers ask AI about APIs, code, or technical specs and receive precise references to the documentation.
Product catalogue search
E-commerce: a customer describes a need → AI finds the most suitable products from the catalogue.
Financial report analysis
AI analyses financial statements, detects anomalies, compares periods, and generates summaries.

Frequently asked questions
What is a RAG system?+
RAG (Retrieval-Augmented Generation) is an AI architecture that finds relevant sections in your documents and generates a precise answer. The AI does not hallucinate because it only uses your data.
What document types can be used?+
PDF, Word (.docx), Excel (.xlsx), PowerPoint, Notion pages, Confluence, website content, emails, and more.
How much does RAG system development cost?+
Simple RAG (single document type) — €2,000–5,000. Mid-size (multiple integrations, authentication) — €5,000–10,000. Enterprise — €10,000–15,000+.
Is my data secure?+
Data is stored on your server or in a private cloud (not on OpenAI servers). A specialist can build a RAG system that operates without sending data to third parties.
