Every quiz app gives you four options to pick from, and recognizing the right answer is much easier than knowing it. Nadir has no multiple choice. You type your answer in plain text and an LLM grades it 0-100 against a reference solution, then tells you what you missed.
I built this to prepare myself for technical interviews but the trivia topics turned out to be more popular among my friends, so Nadir has more than just technical topics - there's trivia about TV shows, movies and books too.
