Something that can scour a confined set of structured and unstructured data and return information when queried based on that data. Imagine a bunch of word documents containing letters and reports and memos. Now I want to query all of that info and ask for things based on a prompt and which files would be relevant. edit: Do tell me if you work on this. I came to "ask hn" to literally ask someone to work on this.
