Quick answerA RAG chatbot is a conversational assistant that retrieves relevant passages from your knowledge base at each turn and uses them to answer, with citations, instead of relying on the model’s memory. It stays current as content changes, handles phrasing it has never seen, and can say “I don’t know” when the evidence is weak.

Scope of work

Conversation design

Turn handling, memory, clarifying questions, and a tone that fits your brand.

Escalation & handoff

Warm transfer to a human agent, passing the conversation and the sources used.

Permissions & PII

Retrieval scoped to entitlements where relevant; PII handling and redaction.

Analytics & improvement

Deflection and escalation metrics, plus a feedback loop into the evaluation set.

RAG Chatbot Development Services: frequently asked questions

A RAG chatbot is a conversational assistant that retrieves relevant passages from your knowledge base at each turn and uses them to answer, with citations, instead of relying on the model's memory. It stays current as content changes and can say 'I don't know' when evidence is weak.

Traditional chatbots follow scripted intents and decision trees that are costly to maintain. A RAG chatbot answers open questions directly from your content, handles phrasing it has never seen, and is updated by updating documents — not by rebuilding flows.

Your website and help centre, in-product, Microsoft Teams or Slack, and support platforms like Zendesk, Salesforce and ServiceNow — with escalation and warm handoff to a human agent, passing along the conversation and sources.

A versioned evaluation set of real questions with graded answers, groundedness and helpfulness scoring, deflection and escalation analytics, and a feedback loop that turns thumbs-down and agent corrections into new evaluation cases and retrieval fixes.

A RAG chatbot is conversational and usually customer- or support-facing. An AI knowledge assistant is oriented to internal knowledge work and tooling — search, drafting and synthesis across many sources. We build both; the retrieval core is shared.
