RAG System

RAG System Development

We build RAG (Retrieval-Augmented Generation) systems that let generative AI instantly search, summarize, and answer from your vast internal documents. From vector DB selection to document preprocessing and hybrid search, we deliver precision-focused architectures.

Common Challenges We Solve

  • Need a way to search across internal manuals and FAQs
  • Knowledge gets buried in existing document management systems
  • Want to reduce onboarding time for new employees
  • Cross-department information sharing is not working well
  • Want AI to answer questions based on company-specific data

Benefits

Dramatically Better Search

Semantic search understands intent, not just keywords, leading to faster discovery

Instant Knowledge Access

Extract relevant information from scattered documents and auto-generate answers

Always Up-to-Date

Index updates automatically when documents change, ensuring answers reflect the latest info

Services

Vector DB Design & Setup

We select the optimal vector database (Pinecone, Qdrant, pgvector) for your use case, balancing search accuracy and cost in the architecture.

  • Vector DB Selection & Benchmarking
  • Schema Design & Index Optimization
  • Scalability Planning
  • Cost Estimation & Operations Design

Document Parsing & Preprocessing

Parse documents from diverse formats (PDF, Word, Confluence, Notion) and apply effective chunking and embedding strategies.

  • Multi-format Support
  • Chunking Strategy Design
  • Metadata Extraction & Tagging
  • Embedding Model Selection

Hybrid Search Implementation

Combine vector and keyword search with re-ranking to deliver highly accurate, relevant results at the top.

  • Semantic Search
  • Keyword Search Fusion
  • Re-ranking Model Integration
  • Search Accuracy Tuning

Security & Access Control

Implement role-based access control within the RAG system to prevent sensitive data leaks, with built-in audit logging.

  • Role-Based Access Control
  • Document-Level Permissions
  • Audit Logs & Usage Tracking
  • Sensitive Data Filtering

Implementation Process

01

Requirements & Data Survey

Understand document types, volume, and update frequency. Clarify search requirements and integration points.

02

Architecture Design & PoC

Select vector DB, embedding model, and search method. Validate search accuracy with a small dataset.

03

Full Build & Tuning

Index all documents and optimize search quality. Develop UI and API integrations in parallel.

04

Launch & Continuous Improvement

Analyze usage logs to continuously improve accuracy and maintain the document update pipeline.
