If you've ever used Apple's Siri, you're using a natural language interface. If you've ever picked up the phone to your IT department and asked them to find some data for you, you're still using a natural language interface. Delver lets you ask plain-English questions, and get answers from your own database or app.
You've got the data, but perhaps people are struggling to get answers out of it. Delver gives you and your users a natural language interface to your data - ask plain English questions, get the answers out.
With Delver, there's no more need to phone the IT department, create new reports or constantly upgrade your app's dashboard. Deploy one text box, and you're done!
