Retrieval-Augmented Generation

RAG Application Development: AI Knowledge Base & Search

Your company knowledge sits in PDFs, drives, wikis, tickets and databases. We build RAG systems that search all of it and answer questions in plain language, citing the exact source, so people stop hunting for information.

  • Your data stays yours
  • Accuracy tested before go-live
  • Works with your CRM, ERP & WhatsApp

What this covers

  • AI Search Engine
  • AI Knowledge Base
  • LangChain Development
  • Vector Database Integration
  • RAG Systems

Typical timeline

Proof of concept in 3–4 weeks; production rollout typically 6–12 weeks.

Who it is for

Who our RAG Development service is for

Good RAG is mostly engineering: clean ingestion, smart chunking, hybrid search, re-ranking and permissions that mirror your existing access rules. We build and evaluate each layer so answers stay accurate as your content grows.

Capabilities

What is included in RAG Development

AI knowledge base

A single question box across documents, wikis and FAQs, answering with citations and links to sources.

AI search engine

Semantic plus keyword search that understands intent, synonyms and Hindi-English queries.

Vector database integration

Embeddings stored in pgvector, Qdrant, Pinecone or Weaviate with metadata filters and fast retrieval.

LangChain & LlamaIndex pipelines

Ingestion, chunking, re-ranking and answer generation pipelines built on proven frameworks.

Permission-aware retrieval

Users only see answers from documents they are allowed to access, enforced at query time.

Evaluation & freshness

Automated accuracy tests and scheduled re-indexing so answers stay right as documents change.

How we work

A clear, step-by-step delivery process

You always know what happens next, who is responsible and what you will receive at each stage.

Typical timeline

Proof of concept in 3–4 weeks; production rollout typically 6–12 weeks.

  1. 01

    Source inventory

    We list content sources, formats, owners and access rules.

  2. 02

    Ingestion pipeline

    Documents are parsed, cleaned, chunked and embedded.

  3. 03

    Retrieval tuning

    Hybrid search and re-ranking are tuned on real questions.

  4. 04

    Answer layer

    Prompting, citations and refusal rules are implemented.

  5. 05

    Evaluation & launch

    Accuracy is measured on a question bank before go-live.

Deliverables

What you receive

  • RAG pipeline and indexed knowledge base
  • Chat and search interface (web, Teams, Slack or WhatsApp)
  • Access-control integration
  • Evaluation question bank and accuracy report
  • Re-indexing and monitoring jobs
  • Admin console and documentation

We recommend tools based on your scale, budget and existing systems, not on what is fashionable. Every choice is explained in the proposal.

Engagement models

Choose how we work together

Proof of concept

A 3–4 week pilot on your own data with agreed accuracy targets, so you see real results before scaling.

Most chosen

Production build

Hardened integration, guardrails, monitoring and admin controls, delivered in milestones with a fixed quote.

Managed AI operations

Ongoing prompt and model tuning, evaluation runs, cost monitoring and feature additions on a monthly plan.

How pricing works: AI projects are priced in two stages: a fixed-price proof of concept, then a production quote based on what the pilot proves. Model and API usage costs are estimated upfront and billed at actuals.

FAQs

RAG Development: frequently asked questions

What is RAG and why not just use ChatGPT?

Retrieval-augmented generation first finds the relevant passages in your own documents and then asks the model to answer only from them. Public ChatGPT does not know your internal content and cannot cite it; RAG does, and it keeps data under your control.

Which document types can you index?

PDFs, Word and Excel files, scanned documents (via OCR), web pages, Confluence or Notion wikis, Google Drive, SharePoint, helpdesk tickets and database records are all supported.

How do you stop the AI from making things up?

Answers are generated only from retrieved passages, each answer cites its sources, and the system says it does not know when the documents do not cover a question. We measure this on a test set before launch.

Will employees see documents they should not?

No. Retrieval respects the permissions of the source systems or the roles you define, so each user only gets answers from content they are allowed to read.
