AI enterprise search connects to the places a company's knowledge already lives — documents, wikis, chat, tickets, code — and answers questions across all of them in one place, with the source attached. The hard part is not the model; it is permissions. A good tool shows each person only what they could already open, in real time, as access changes. Evaluate that before anything else, because a search that leaks a document is worse than one that misses it.

A chatbot answers from what its model was trained on; enterprise search retrieves from your company's own documents and systems, respects who may see what, and cites the source. The model only writes the answer; the retrieval layer is the product.
Often yes, at least the passages used to write an answer, unless the vendor runs models inside your environment or offers a private deployment. The data-processing terms and the model provider's retention policy are the two documents to read before a pilot.
