RAG Chatbot: How to Build an Assistant with Company Documents
RAG is an architecture that lets AI answer using your company's documents and data. Instead of relying only on the model's general knowledge, the system retrieves relevant passages and uses them as context.
When RAG makes sense
- You have many PDFs, manuals, proposals, or internal policies. - The team loses time searching for answers. - Answers need to cite a source. - Content changes often. - You do not want to train a model from scratch.
Good practices
- Show the source used in the answer. - Admit when there is not enough information. - Separate documents by area and permission. - Measure unanswered questions to improve the base. - Provide a panel for document updates.
Conclusion
A well-built RAG chatbot saves time and preserves internal knowledge. The key is a clean knowledge base, access control, and measurable usage.
