Internal AI Assistants

Your Organisation’s Knowledge, Made Instantly Searchable

HR manuals, legal contracts, technical guides, compliance frameworks — your organisation has years of institutional knowledge locked in documents nobody can find. We build internal AI assistants that make it instantly retrievable, with citations and GDPR compliance built in.

Unlock siloed company knowledge across every department

Internal knowledge assistants deliver the highest ROI when deployed on document-heavy workflows. Here are the four most common implementations.

📋

HR policy & procedure assistant

Employees ask questions about leave entitlements, expense policies, or onboarding requirements in plain language — and receive an accurate, cited answer from the latest HR manual. HR teams stop answering the same 30 questions repeatedly.

Legal contract intelligence

Legal and procurement teams search thousands of contracts for specific clauses, renewal dates, or liability limits in seconds. The assistant points to the exact clause and document source.

Technical documentation retrieval

Engineers query manuals, specifications, and product documentation in natural language. Cuts research time from hours to seconds on complex technical questions.

Regulatory compliance Q&A

Compliance teams ask questions about applicable regulations, internal policies, and audit requirements — with full source attribution for every answer.

How a RAG knowledge assistant works

Retrieval-Augmented Generation (RAG) grounds the AI in your actual documents. The model never invents answers — it retrieves and summarises from verified sources.

01

Document ingestion

Your documents (PDFs, Word, SharePoint, databases) are ingested, chunked intelligently, and stored as vector embeddings in Azure AI Search.

02

Query processing

When a user asks a question, it is converted to an embedding vector and matched against your document store using semantic similarity search.

03

Context assembly

The top-matching document chunks, along with the user question, are assembled into a prompt. Hybrid search (vector + keyword) catches both semantic intent and exact matches.

04

Grounded generation

Azure OpenAI generates an answer strictly from the retrieved context. Hallucinations are structurally prevented because the model is constrained to the provided source material.

05

Source citation

Every response includes traceable citations — the document name, section, and page where the answer was found. Compliance teams can verify any response.

Engineering transparency

How we select the right embedding model for your workload

Every RAG system requires an embedding model to convert text into vector representations. The choice materially affects accuracy, latency, and operating cost. We evaluate the options openly with every client before making a recommendation.

For a recent client with a 50,000-document technical library requiring daily updates and sub-second query latency, we evaluated three OpenAI embedding models before recommending text-embedding-3-small. Here is why:

ModelDimensionsCost / 1M tokensStrengthTrade-off
text-embedding-ada-0021,536€0.10Good general purposeLarger index size
text-embedding-3-small1,536 (configurable)€0.02High accuracy at low costSmaller community vs ada-002Our recommendation
text-embedding-3-large3,072€0.13Highest accuracy6.5× the cost of 3-small

Why text-embedding-3-small for this client: At 50,000 documents with daily ingestion runs, the 5× cost advantage over text-embedding-3-large reduced ongoing operating cost by ~€280/month with no measurable accuracy loss on domain-specific technical terminology. The configurable dimension size allowed us to reduce the Azure AI Search index by 40%, cutting infrastructure cost further. This decision alone paid for the IITS engagement within three months.
