Frequently Asked Questions
What is RAG and why do I need it?
RAG (Retrieval-Augmented Generation) combines a vector search engine with an LLM. When a user asks a question, the system retrieves the most relevant documents and uses the LLM to generate an answer grounded in that content — eliminating hallucinations.
What types of documents can the RAG system handle?
PDFs, Word documents, Excel files, CSVs, HTML pages, text files, Confluence pages, Notion docs, SharePoint content, and any structured/unstructured text.
How do you prevent the AI from making up answers?
We implement strict grounding — if relevant content isn't found in the knowledge base, the system responds with 'I don't have information on this.' We also include confidence scoring and source citations.
Is our data secure?
Yes. Your documents are stored and processed in your own cloud environment. We never send raw document content to LLM providers — only the retrieved context needed to answer each query.
