About Question and Answer Chain
Question and Answer Chain is an n8n AI node that connects a language model to a knowledge base, enabling it to answer questions based on your own documents and data. Rather than relying on the model’s general training, the chain retrieves relevant context from your vector store or document collection and feeds it to the LLM alongside the user’s question — a pattern known as Retrieval-Augmented Generation (RAG).
This is the foundation for building internal knowledge bots, customer support assistants, and document Q&A systems. Instead of employees searching through PDFs, wikis, or shared drives, they ask a question in plain language and get an accurate answer grounded in your actual content. The chain handles the retrieval, context assembly, and response generation in a single workflow step.
At Osher Digital, we use the Question and Answer Chain node as a core building block for RAG-based AI agents. For one client, we built a medical document classification system that answers clinician queries against a library of clinical guidelines — detailed in our AI medical document classification case study. Our custom AI development team configures the chain with the right retrieval strategy, prompt templates, and model settings for each use case.

How it works
We work hand-in-hand with you to implement Question and Answer Chain
As Question and Answer Chain consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate Question and Answer Chain with integrate and automate 800+ tools.
Step 1
Process Audit
We review your existing knowledge management setup — where documents live, how employees currently find answers, and which questions come up repeatedly. This tells us what content to prioritise for the knowledge base and where the Q&A system will deliver the most value.
Step 2
Identify Automation Opportunities
We identify specific use cases for the Q&A Chain — internal help desk, customer support, compliance queries, or technical documentation lookups. Each use case has different requirements for accuracy, speed, and source citation that shape the implementation.
Step 3
Design Workflows
We architect the full RAG pipeline: document ingestion, vector store configuration, retrieval strategy, prompt templates, and the Q&A Chain node setup. The design includes how users will interact with the system — via Slack, a web chat, email, or an internal tool.
Step 4
Implementation
We build the document processing pipeline, set up the vector store, configure the Q&A Chain with your chosen LLM, and connect the user interface. This includes tuning chunk sizes, overlap settings, and retrieval parameters for your specific content.
Step 5
QA Review
We test the system with real questions from your team, comparing answers against known correct responses. We tune the retrieval and prompts until accuracy meets your standards, and verify that source citations correctly point to the right documents.
Step 6
Support & Maintenance
We maintain the system as your knowledge base grows — monitoring answer quality, updating the ingestion pipeline for new document types, and tuning the retrieval as your content library expands. Regular quality reviews keep the system accurate over time.
