Ask HN: Any good use cases for an NLP Search based data assistant for ur team?

I love the idea of having a personal(custom) search tool, making instant reports/proposals/concepts and able to track data with easy keywords. The only thing, I'm doubtful about is the information accessiblity within the organization and the teams. Can we limit and share relevant information team-wise and individually? Please talk about security of the data with the tool. This tool applies to every sector and that is it's biggest speciality. Would like to explore more.
