It's called Relic AI (https://relic-app.com) and it's in open beta. You can ask it questions, and it answers only from what you've saved, with links back to the sources.
I'm a computer science engineer and Relic's COO. Before Relic I built SquadUp, an app for organizing sports activities in Sarajevo.
