Retrieval-augmented generation grounds every AI answer in your own product docs. For sales chatbots, that's the difference between accurate quotes and hallucinated features.

How RAG works, in 4 steps

Retrieve When a visitor asks a question, the top matching chunks are pulled by semantic similarity.
Augment Those chunks are inserted into the prompt as context for the LLM.
Generate The LLM answers using the retrieved context, grounded in your source of truth.

Lower cost, higher accuracy on your specific product.

Frequently asked questions

What is a RAG chatbot?

A RAG (retrieval-augmented generation) chatbot retrieves relevant chunks of your own content docs, URLs, pricing, FAQs and passes them to the LLM as context before it answers. The result is grounded in your product, not the model's training data.

Why does RAG matter for sales?

Sales visitors ask specific questions: integrations, pricing tiers, security posture, edge cases. A non-RAG chatbot will hallucinate. RAG ensures the answer comes from your source of truth.
