If anyone wants to steal my million dollar startup idea, please credit my HN username in your IPO announcement: we need an app that integrates simple itinerary creation (airbnb/tripadvisor/google-sheets), itinerary management (tripit), restaurant selection (yelp), expense tracking (Splitwise), and this (ad-hoc location-based information of a vaguely “historical” or “informative” nature). Of course all with a sprinkling of LLM-magic on top for UX niceties.
So one app could connect a group over the course of a trip, helping them plan it both in advance and in the moment. Call it… _The Worldbook_.
