AI assistant
What is an AI assistant?
An AI assistant helps a person with a task, such as writing, searching or summarising, but takes no actions by itself unless the user asks.
ChatGPT, Microsoft Copilot and Claude are well-known examples. They make individual employees faster, but the person keeps doing the work and deciding. That is how an assistant differs from an AI agent, which carries out tasks in your systems by itself.
An assistant only becomes truly valuable when it knows your company’s knowledge. With RAG you let it answer from your own documents, with the source attached.
See also Microsoft Copilot.
