The data problem every organisation has

Your company has years of accumulated knowledge — internal documents, meeting notes, Slack conversations, support tickets, research reports, contracts, product specs. This knowledge is valuable, but it’s scattered across dozens of tools and impossible to search effectively.

According to a 2024 IDC report, knowledge workers spend an average of 2.5 hours per day searching for information they need to do their jobs. That’s over 30% of a workday lost to hunting through shared drives, Confluence pages, email threads, and Slack channels.

Traditional enterprise search is keyword-based. If you search for “customer churn analysis Q3,” you’ll find documents that contain those exact words. But you won’t find the presentation titled “Retention Metrics Review — September” that contains exactly the analysis you need, because it uses different words for the same concept.

AI-powered data intelligence solves this by understanding meaning, not just matching keywords. It lets your team ask questions in plain language and get accurate, sourced answers from your own data.

How it works: RAG systems explained simply

The technology behind this is called Retrieval-Augmented Generation, or RAG. It sounds complex, but the concept is straightforward:

📄
Your Documents
✂️
Chunk & Embed
🗄️
Vector Database
User Query
🔍
Retrieve Context
🤖
LLM Answer
  1. Your documents are processed — Every document, page, and record is broken into small sections (called “chunks”) and converted into a mathematical representation that captures its meaning (called an “embedding”). These embeddings are stored in a specialised database.

  2. Someone asks a question — When a user types “What was our customer churn rate in Q3 and what caused it?”, the system converts this question into the same kind of mathematical representation.

  3. Relevant chunks are found — The system compares the question’s representation against all the stored document chunks and finds the most relevant ones — even if they use completely different words.

  4. An LLM generates the answer — The relevant document chunks are passed to a large language model (like GPT-4o or Claude) along with the question. The LLM reads the retrieved context and generates a conversational answer, citing the specific documents it used.

The result: instead of spending 45 minutes searching across five different tools, the user gets a sourced answer in under 10 seconds.

The technology stack

Vector databases

These are the specialised databases that make semantic search possible. The most popular options:

  • Pinecone — A fully managed cloud service. You don’t need to set up or maintain servers. It’s the most popular choice for companies that want to get started quickly without infrastructure complexity. Used by companies like Shopify and Notion.

  • Weaviate — An open-source vector database that can be self-hosted or used as a cloud service. Popular with companies that want more control over their data and infrastructure.

  • Chroma — A lightweight, open-source option that’s excellent for prototyping and smaller datasets. Many teams start with Chroma to prove the concept, then migrate to Pinecone or Weaviate for production.

  • Qdrant — A high-performance vector database built in Rust. Popular with teams processing very large datasets that need fast query times.

Orchestration and retrieval

  • LangChain — The most widely used framework for building RAG systems. It handles the entire pipeline: document loading, chunking, embedding, retrieval, prompt construction, and LLM querying. Think of it as the plumbing that connects all the pieces.

  • LlamaIndex — Similar to LangChain but specifically optimised for document-heavy applications. It excels at handling complex document structures like PDFs with tables, nested hierarchies, and mixed-format content.

Evaluation and monitoring

  • RAGAS — An open-source framework specifically for evaluating RAG systems. It measures answer relevance, faithfulness (does the answer match the source documents?), and context relevance (did the system retrieve the right documents?).

  • Langfuse — Tracks every query, retrieval, and response in production. Essential for understanding where the system struggles and what needs improvement.

Real-world applications

Internal knowledge base Q&A

The most common application is a “chat with your docs” system for employees. Instead of searching a wiki, employees ask questions in natural language and get immediate answers.

Dropbox built an AI-powered search feature called Dropbox Dash that searches across connected tools (Google Docs, Slack, Notion, Salesforce) and returns unified answers. Their internal testing showed employees found information 30% faster compared to searching each tool individually.

A practical example: a new employee at a 500-person company needs to understand the expense reimbursement process. Instead of searching the HR wiki, scrolling through a 20-page policy document, and messaging their manager for clarification, they ask: “How do I submit an expense report for a client dinner over $200?” The system retrieves the relevant policy section and responds with the specific steps, approval thresholds, and required documentation.

Customer-facing knowledge bases

E-commerce companies, SaaS platforms, and service businesses are building AI-powered help centres where customers can ask questions and get instant answers from the company’s documentation.

Shopify’s Sidekick assistant uses RAG to answer merchant questions about their platform — everything from “How do I set up international shipping?” to “What’s the best way to handle returns for custom products?” It draws from Shopify’s extensive help documentation, community forums, and best-practice guides.

According to Zendesk’s 2025 Customer Experience Trends report, 72% of customers prefer finding answers through self-service when the option is good enough. AI-powered knowledge bases make self-service dramatically better than traditional FAQ pages.

Law firms deal with enormous volumes of documents — contracts, case files, regulations, correspondence. Finding specific clauses, comparing terms across agreements, or identifying risks requires hours of careful reading.

Harvey AI, built specifically for legal work, uses RAG to let lawyers query document sets in natural language. A lawyer can upload 50 contracts and ask: “Which of these agreements have a change-of-control clause, and what are the notification requirements?” The system identifies the relevant clauses across all documents and presents them with citations.

Casetext CoCounsel offers similar capabilities for legal research — searching case law, analysing depositions, and drafting document summaries.

Financial research and analysis

Investment firms and financial analysts process hundreds of reports, earnings calls, and regulatory filings. AI systems can ingest these documents and answer specific analytical questions.

Kensho, used by S&P Global, processes financial data and research documents to answer analyst queries. An analyst might ask: “What did the CEO of Company X say about margin expansion in their last three earnings calls?” and get a synthesised answer with direct quotes and citations.

For smaller firms, a custom RAG system built with LangChain and Pinecone can provide similar capabilities over their proprietary research library.

Healthcare documentation

Hospitals and clinics generate massive amounts of documentation — patient records, clinical notes, research papers, protocol documents. AI systems can help clinicians find relevant information quickly.

Nuance DAX (used by over 550,000 physicians according to Microsoft) combines AI-powered documentation with intelligent retrieval, helping doctors access patient history, drug interaction information, and clinical guidelines during consultations.

Research and academic applications

Universities and research organisations use RAG systems to search across their published papers, grant applications, and internal research notes. A researcher can ask: “What methods have we used for sentiment analysis in published papers since 2022?” and get a comprehensive answer drawing from the institution’s entire research output.

Building a data intelligence system

Step 1: Audit your data sources

Before building anything, catalogue where your organisation’s knowledge lives:

  • Internal wikis (Confluence, Notion, Google Sites)
  • Document storage (Google Drive, SharePoint, Dropbox)
  • Communication archives (Slack, email, Teams)
  • Ticketing systems (Zendesk, Jira, Intercom)
  • CRM records (Salesforce, HubSpot)
  • Specialised databases and tools

Step 2: Prioritise by value and feasibility

Not all data sources are equally valuable or easy to integrate. Start with structured, text-heavy sources like wiki pages and help documentation. These are easy to ingest and produce the best results quickly. Slack messages and email archives are harder to work with because they’re noisy and context-dependent.

Step 3: Build the pipeline

A specialist sets up the ingestion pipeline: connecting to each data source, extracting text, splitting it into meaningful chunks, generating embeddings, and storing them in the vector database. This is the most technically complex step and typically takes 1–3 weeks depending on the number of sources and their formats.

Step 4: Tune retrieval quality

Raw RAG systems work reasonably well out of the box, but tuning makes a significant difference. The specialist adjusts chunk sizes, embedding models, retrieval strategies, and re-ranking algorithms to improve answer quality. They also craft the system prompt that instructs the LLM on how to answer — what format to use, when to say “I don’t know,” and how to cite sources.

Step 5: Deploy and iterate

The system goes live — typically as a chat interface, a Slack bot, or an API endpoint that other tools can query. Usage data reveals what people ask, where the system struggles, and what data sources are missing. The specialist iterates based on this feedback, adding data sources, improving retrieval, and refining prompts.

What to expect

A well-built RAG system answering questions from a company’s internal documentation typically achieves:

  • 85–95% answer accuracy on questions that are answerable from the indexed documents
  • Under 5 seconds response time for most queries
  • Significant time savings — most organisations report 40–60% reduction in time spent searching for information

The system improves over time as more data is indexed and retrieval is tuned based on real usage patterns.
