RAG Knowledge Base Development

Your team loses 9+ hours per week per person searching for answers that should be instant. A RAG knowledge base gives them cited answers from your own documents in under 2 seconds. Production-ready in 3-4 weeks.

Knowledge workers spend 1.8 hours per day searching for information across documents, wikis, and shared drives (McKinsey). For a 50-person team, that is over $100,000 per month in lost productivity. A RAG (Retrieval-Augmented Generation) knowledge base cuts that waste by 70-90% by transforming your existing documents into an AI-powered system that answers natural language questions with accurate, cited responses in under 2 seconds. Unlike ChatGPT or generic AI tools that hallucinate, RAG grounds every answer in your actual content and shows exactly which document, page, and section the answer came from. Unlike SharePoint search or Confluence search that miss results when users do not know the exact terminology, RAG understands meaning and finds what your team needs regardless of how they phrase the question. We build production-ready RAG applications that ingest 15+ document formats, scale to 100,000+ documents, and include role-based access control so sensitive content stays restricted.

The problem you already know

The Hidden Cost of Bad Document Search

Every day your team cannot find answers quickly, your business pays for it in wasted hours, lost deals, compliance risk, and institutional knowledge that walks out the door.

$6,750 /day

Lost to Bad Document Search

Knowledge workers spend 1.8 hours per day searching for information (McKinsey). For a 50-person team at $75/hr, that is $6,750 per day in wasted productivity. Over $135,000 per month spent on searching, not working.

6-12 months

To Replace Lost Knowledge

When your senior architect or compliance lead leaves, years of institutional knowledge walk out the door. Recruiting, onboarding, and ramping a replacement takes 6-12 months and costs 1.5-2x their annual salary.

15-45 min

Per Document-Dependent Ticket

Support and operations tickets that require looking up document answers take 15-45 minutes to resolve manually. With 200+ such tickets per month, that is $5,000-$15,000 per month in avoidable labor cost, plus customer churn from slow responses.

A RAG knowledge base eliminates all three costs.

Starting at $15,000, most RAG deployments pay for themselves within the first 1-2 weeks of operation. Your documents become an asset that works 24/7, not a liability your team has to manually search.

What Is RAG (Retrieval-Augmented Generation)?

RAG is an AI architecture that combines document retrieval with text generation to produce accurate, cited answers from your own content, not the internet.

Instead of relying on a model's training data (which can be outdated or hallucinated), RAG retrieves the most relevant content from your document library in real-time and uses it as context to generate precise, grounded answers. Every response includes citations to the exact source documents, so your team can verify answers instantly.

1

Query

User asks a natural language question

2

Retrieve

System searches your documents using semantic understanding

3

Augment

Retrieved passages are fed to the AI model as context

4

Generate

AI produces a cited answer grounded in your content

Why RAG Matters for Enterprise Knowledge Management

  • Answers are grounded in YOUR content, not the internet or outdated training data
  • Every response cites specific documents, pages, and sections for instant verification
  • Documents can be updated, added, or removed anytime without retraining the AI model
  • Sensitive data stays in your infrastructure and is never used to train third-party models
  • Scales to 100,000+ documents with sub-2-second response times

Why Choose Salt Technologies AI for RAG Development

We are not a generic dev shop. Here is what makes our RAG knowledge base development different.

Every Answer Cites Its Source

Our RAG systems link every response to the specific document, page, and section it came from. Users can verify answers instantly with a single click, eliminating trust issues with AI-generated content and creating auditable answer trails for compliance.

Support for 15+ Document Formats

We ingest PDF, DOCX, XLSX, CSV, HTML, Markdown, Confluence pages, Notion databases, Google Docs, SharePoint libraries, Zendesk articles, and more. Custom parsers are available for proprietary formats, scanned documents, and legacy file types.

Hybrid Search for Maximum Accuracy

We combine semantic search (understanding meaning) with keyword search (matching exact terms) in a single retrieval pipeline. This hybrid approach catches results that pure semantic or pure keyword search would miss, achieving 85-95% answer accuracy.

Role-Based Access Control Built In

Different teams see only the documents they are authorized to access. Sensitive HR, legal, financial, and executive documents are restricted by role, department, or security clearance level. Access rules sync with your existing identity provider.

Admin Panel for Non-Engineers

Your team can add, remove, and update documents, view usage analytics, identify knowledge gaps from unanswered questions, and tune retrieval settings through a web dashboard without writing code or filing engineering tickets.

Built to Scale to 100,000+ Documents

Our RAG architectures use production-grade vector databases (Pinecone, Weaviate, Qdrant) optimized for large-scale semantic search. Retrieval speed remains under 2 seconds even with 100,000+ indexed documents. Ingestion pipelines handle batch and incremental updates efficiently.

RAG Knowledge Base Development: Frequently Asked Questions

How much does RAG knowledge base development cost?
Our RAG Knowledge Base package starts at $15,000 for a standard deployment with one to three document sources and a web-based interface. Pricing depends on document volume, number of sources, access control complexity, and accuracy requirements. Enterprise RAG systems with HIPAA or SOC2 compliance typically range from $20,000 to $35,000. Multi-department deployments with role-based access and API integrations may range from $25,000 to $40,000. You receive a fixed quote after the data audit phase, before any build work begins.
What is RAG and why is it better than fine-tuning for enterprise knowledge bases?
RAG (Retrieval-Augmented Generation) searches your documents in real-time and feeds relevant context to the AI model before generating an answer. Unlike fine-tuning, RAG does not require retraining the model when documents change, works with documents you add or update at any time, provides citations for every answer, and keeps your data separate from the AI model. Fine-tuning bakes knowledge into model weights, which means it goes stale, cannot cite sources, and requires expensive retraining when content changes. For enterprise knowledge bases where documents update frequently and citations are required, RAG is the superior approach.
What document formats does your RAG system support?
We support 15+ document formats: PDF (including scanned PDFs with OCR), DOCX, XLSX, CSV, HTML, Markdown, plain text, Confluence pages, Notion databases, Google Docs, SharePoint libraries, Zendesk articles, Intercom help center content, and email archives. We build custom parsers for proprietary formats, legacy file types, and structured databases. During the data audit phase, we inventory all your document sources and confirm format support before building.
How accurate are the answers from a RAG knowledge base?
RAG accuracy depends on document quality, chunking strategy, and retrieval tuning. We typically achieve 85-95% answer accuracy for well-structured document sets after the testing and tuning phase. Every answer includes citations to the source document, page, and section so users can verify. Low-confidence answers are flagged automatically. We establish accuracy benchmarks during the data audit phase and test against them with real questions from your team before deployment.
How long does it take to build a RAG knowledge base?
Typically 3-4 weeks from kickoff to production deployment. Simple RAG systems with a single document source and straightforward access rules can be ready in 3 weeks. More complex builds with multiple sources, strict compliance requirements, role-based access, and API integrations may take 4 weeks. Timeline is defined during the data audit phase and fixed before development begins.
Can I add, update, or remove documents after the RAG system is deployed?
Yes. The admin panel lets you add new documents, update existing ones, or remove documents at any time. New documents are automatically parsed, chunked, embedded, and indexed without system downtime. Incremental updates typically process within minutes. Bulk re-indexing for large document library changes can be scheduled during off-peak hours.
Is your RAG system HIPAA compliant for healthcare use?
Yes, we build HIPAA-compliant RAG systems for healthcare organizations. This requires encrypted storage at rest and in transit, comprehensive audit logging, role-based access controls, a Business Associate Agreement (BAA) with the cloud provider, and PHI-safe model configurations. HIPAA-compliant RAG deployments typically range from $25,000 to $40,000 depending on complexity. We have experience building compliant knowledge retrieval systems for healthcare clients handling clinical guidelines, patient education materials, and internal medical documentation.
How does RAG handle very large document libraries with 100,000+ documents?
RAG scales well to hundreds of thousands of documents. We use production-grade vector databases (Pinecone, Weaviate, Qdrant, or pgvector) optimized for large-scale semantic search. Retrieval speed remains under 2 seconds even with 100,000+ indexed documents. For very large libraries, we implement tiered indexing strategies, metadata filtering to narrow search scope, and caching for frequently asked questions. The ingestion pipeline handles both batch imports and incremental daily updates.
What is the difference between RAG and traditional keyword search?
Traditional keyword search matches exact words: if you search for "vacation policy" it only finds documents containing those exact words. RAG uses semantic search to understand meaning: searching "how many days off do I get" finds your PTO policy even though those exact words never appear in the document. RAG also generates natural language answers instead of just returning a list of documents, cites the specific source, and handles follow-up questions. The result is dramatically higher findability and faster time to answer compared to SharePoint search, Confluence search, or Google Drive search.
Can the RAG system integrate with Slack, Microsoft Teams, and other tools?
Yes. We expose the RAG engine as a REST API that can power integrations with Slack bots, Microsoft Teams apps, internal portals, CRM systems, helpdesk tools, and custom applications. The web UI is one interface; the API lets you build any interface you need. Most clients deploy the web UI first and add Slack or Teams integration as a fast follow-up.
How do you prevent the RAG system from hallucinating or giving wrong answers?
We implement multiple layers of hallucination prevention. First, RAG grounds every answer in retrieved document content, not the model general knowledge. Second, every answer includes citations that users can verify. Third, we implement confidence scoring that flags low-confidence answers. Fourth, we configure the system to respond with "I could not find this in the documents" rather than guessing when retrieval confidence is low. Fifth, we test accuracy extensively with real questions before deployment and tune the system until it meets your accuracy benchmarks.
Can RAG work with multiple languages?
Yes. We configure multilingual RAG using embedding models that support cross-language retrieval. Users can ask questions in one language and retrieve answers from documents written in another. We support English, Spanish, French, German, Portuguese, Chinese, Japanese, Korean, Hindi, and 20+ additional languages. Multilingual support adds $2,000 to $5,000 depending on the number of languages and document translations required.
What vector database do you use for RAG?
We select the vector database based on your requirements. Pinecone for fully managed, serverless deployments with minimal operational overhead. Weaviate for hybrid search with built-in keyword and semantic capabilities. Qdrant for high-performance, self-hosted deployments. pgvector for teams that want to keep everything in PostgreSQL. Each has trade-offs in performance, cost, and operational complexity. We recommend the best option during the data audit phase based on your document volume, latency requirements, and infrastructure preferences.
Can RAG handle structured data like spreadsheets and databases, not just documents?
Yes. While RAG is most commonly used for unstructured documents (PDFs, articles, policies), we also build systems that query structured data from spreadsheets (XLSX, CSV), databases (PostgreSQL, MySQL, MongoDB), and APIs. For structured data, we use text-to-SQL and tabular retrieval techniques alongside traditional document retrieval. This lets users ask questions that span both documents and structured data in a single query.
Do we own the RAG system code and intellectual property?
Yes. All source code, documentation, configurations, custom parsers, and prompt templates created during the engagement belong to you. There are no licensing fees, no lock-in, and no restrictions on how you use the deliverables. You can modify, extend, or migrate the RAG system independently after handoff. The vector database and infrastructure run in your cloud account. Your documents never leave your infrastructure.
