What is a RAG chatbot and how is it different from ChatGPT

A RAG chatbot answers using your documents, not generic knowledge. Here's how it works and when it pays off.

ChatGPT knows a bit of everything, but nothing about your business: your prices, your hours, your procedures. A RAG chatbot (Retrieval-Augmented Generation) fills exactly that gap.

How it works, in plain words

Before answering, the chatbot searches your documents (price lists, FAQs, manuals, contracts) for the passages relevant to the question. It then builds the answer from those texts, citing real, up-to-date information. If the answer isn't in the documents, it says so instead of making things up.

When it pays off

RAG shines when the same questions arrive every day: customer support, product and service information, onboarding new team members. The chatbot answers instantly, 24/7, in multiple languages, and your team only handles the genuinely complex cases.
