What Is RAG? Retrieval-Augmented Generation Explained for Business Applications
RAG lets AI answer questions from your own documents and data. Here is how it works, where it helps, and what to get right.

We integrate large language models into the applications and workflows you already run — with the same engineering standards as the rest of your system. Software engineers applying proven AI APIs, not an AI research lab.
Practical AI features that solve a specific problem in your product or operations, integrated through well-tested APIs.
Add summarization, drafting, classification and extraction to your application using LLM APIs.
Integrate OpenAI models directly or through Azure OpenAI for Azure-hosted, enterprise-governed deployments.
Build on Claude models via the Anthropic API for long-document reasoning, drafting and tool use.
Question answering and search over your documents using embeddings, vector databases and citation of sources.
Customer-facing or internal assistants that answer from your knowledge base and hand off to humans.
Agents that call your own APIs as tools — with permissions, confirmations and audit logs around every action.
Extract structured data from invoices, forms, contracts and emails into your systems, with human review where needed.
Automate business processes with LLM steps, using code or tools such as n8n connected to your APIs.
Semantic search across your content and natural-language questions over reports and operational data.
A typical retrieval-augmented generation architecture. The model never gets direct access to your database — your backend decides what it sees.
Pick one valuable, measurable task. Collect real examples.
Test models, prompts and retrieval against those examples.
Build it into your backend with security, logging and fallbacks.
Track quality, latency and cost; improve with real usage.
API keys server-side, per-user permission filtering on retrieval, and no direct model access to your database.
Only necessary data is sent to providers; retention and residency requirements agreed up front.
Test sets from real examples so prompt or model changes can be checked before release.
Token usage logging, caching and model selection matched to the task.

Both give you access to OpenAI models. The difference is in security controls, networking, compliance, billing and how fast new models arrive.
Read the articleNo. We integrate established model APIs — such as OpenAI, Anthropic Claude and Azure OpenAI — into your software. We do not train proprietary foundation models. For most business use cases, well-engineered integration of existing models is faster, cheaper and easier to maintain.
Retrieval-augmented generation (RAG) retrieves relevant passages from your own documents or data and gives them to the model with the question, so answers are grounded in your content. You need it when the model must answer from information it was not trained on, such as your policies, manuals or records.
Yes. We commonly add AI features through a backend service in ASP.NET Core or Node.js, which the web or Flutter app calls. API keys and data access stay on the server.
We design integrations so only the data needed for a task is sent to a model provider, use enterprise API terms or Azure OpenAI where required, keep credentials server-side, and log usage. Data-handling requirements are agreed with you before build.
It depends on your quality, cost, latency and data-residency requirements. We often build a thin abstraction so you can compare or switch providers without rewriting your application.
We build a small evaluation set from real examples at the start, test prompts and retrieval against it, and monitor quality and cost once the feature is live.
Bring the problem, the data involved and the system it needs to fit into. We will give you an honest view of what is feasible and how to start small.
