A nugget is the portable form of a paper.
Academic writing is long. Curiosity, on most days, is short. Nugget cuts the idea down to what you can read today.
A card does not replace the source. It carries the core. You keep what you like, you choose your fields, and another nugget arrives the next day.
Nugget is a Turkish product. The interface also speaks English. The daily dose is personal: on the same morning, two people do not read the same six.
