About

Miruma

Miruma starts with a simple feeling: you open a dictionary to look up one word and end up learning something completely different. You read its definition, then the definition of a word you didn’t know. Little by little, you came for one answer and you’re leaving with a handful of discoveries. You weren’t looking for any of them, yet you learned far more than you expected. That’s exactly the idea behind Miruma. Miruma is general knowledge through connections. History, science, nature, art, words, inventions, sport: every topic takes a few minutes to read and ends with questions. Follow the one that intrigues you, then pull the thread as far as you like. ◆ ONE QUESTION LEADS TO ANOTHER Why did 1816 have no summer? How did the bicycle come to be? Where does Frankenstein come from? The fun facts keep coming, and there’s a reason they connect. You don’t just stumble on a random fact: you learn where it comes from, and where it leads. ◆ EVERY LINK SAYS WHY A link with no explanation is just a “see also”. Here, every connection comes with its sentence, and its status: established, debated or legend. When a good story is disputed, Miruma tells you. Spot a mistake? Report it in two taps. ◆ YOUR MAP OF KNOWLEDGE Everything you read connects. Topic after topic, your map grows and shows you the trails you haven’t opened yet. ◆ REMEMBER WHAT STRUCK YOU Save the topics you loved. The quiz only covers your bookmarks, and questions come back at the right time so it sticks. No exam, no grade: only what you chose to remember. ◆ FIVE MINUTES A DAY Topics picked around what makes you curious, a streak to keep alive, a reminder at noon if you want one. The less you come, the less we insist. ◆ AND ALSO • No ads • Topics you’ve read stay available offline • Light or dark, in your color • In English and French Did you know? General knowledge isn’t learned from lists, it holds together through connections. Miruma isn’t another trivia game or an endless feed of facts: it’s a way to understand the world, one question at a time. Learn something new every day, and actually remember it.
