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.
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.
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.
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.
See How Much RAG Could Save YouWhat 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.
Query
User asks a natural language question
Retrieve
System searches your documents using semantic understanding
Augment
Retrieved passages are fed to the AI model as context
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
RAG Knowledge Base Use Cases
See how businesses use RAG-powered knowledge bases to solve real problems and drive measurable results across industries.
Enterprise Document Q&A
Let employees search thousands of internal documents with natural language questions and get cited answers instantly. Reduce the time spent digging through SharePoint, Confluence, Google Drive, and shared folders from hours to seconds. Companies with 10,000+ documents typically see 70-90% reduction in time spent searching for information.
Customer-Facing Help Center AI
Replace static FAQ pages and keyword search with an AI that answers customer questions from your documentation, product guides, and knowledge base articles. Reduce support ticket volume by 40-60% by giving customers instant, accurate answers with links to source documentation.
Compliance and Legal Document Research
Enable legal and compliance teams to query regulatory documents, contracts, policies, and audit trails in natural language. Every answer cites the specific clause, section, and document for verification. Reduce research time for compliance questions from hours to minutes.
Technical Documentation Search
Help engineering teams find answers across API docs, runbooks, architecture documentation, and internal wikis. New team members get up to speed 3-5x faster when they can ask questions in plain language instead of reading through hundreds of pages of documentation.
HR Policy and Employee Self-Service
Give employees instant answers about benefits, leave policies, onboarding procedures, and company guidelines. Reduce HR ticket volume by 50-70% while ensuring employees always get the most current policy information with citations to the official source documents.
Product Knowledge Base for Sales Teams
Enable sales teams to instantly find competitive intelligence, product specifications, pricing details, and case study data during live calls. A RAG-powered knowledge base gives sales reps the specific numbers, features, and comparisons they need in seconds instead of searching across multiple spreadsheets and presentations.
Medical and Clinical Knowledge Retrieval
Build HIPAA-compliant RAG systems for healthcare organizations to query clinical guidelines, drug interactions, treatment protocols, and medical literature. Every answer cites the specific guideline or study, supporting evidence-based decision-making with auditable trails.
Financial Research and Regulatory Compliance
Enable financial analysts and compliance officers to search across regulatory filings, internal policies, audit reports, and market research documents. RAG provides cited answers that create auditable trails for regulatory compliance requirements like SOC2, PCI-DSS, and SEC reporting.

For enterprise knowledge bases where documents change and citations matter, RAG is the clear winner. Fine-tuning is better for brand voice and classification tasks. Traditional search works for simple, keyword-known lookups.
Read our detailed comparison: RAG vs. Fine-TuningWhy 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.
