About Mnemoz
Last updated: October 13, 2026
Mnemoz is a free website to learn and remember general knowledge: history mini-courses, country profiles, geography games and quizzes on history, geography, science, sports, film, nature, society… Every quiz comes with an explanation after each answer, so you learn something even when you get it wrong.
What you will find here
- history mini-courses and a profile for each of the 193 countries, to learn before you practise;
- geography games (capitals, flags, mountains, seas, rivers) on a world map, and spaced repetition of missed questions to remember for longer;
- hundreds of quizzes sorted by theme and by difficulty, from very easy to expert;
- the site fully available in French, English, Italian and Spanish;
- a daily challenge, an Endless mode, rankings, multiplayer live games and ranked duels;
- the ability to create your own quizzes and rate other people's.
How the quizzes are designed
Questions are written or assisted by artificial intelligence tools, then reviewed and organized by theme and by level. Each question comes with a short explanation that gives the context of the answer. We favor stable, verifiable facts and avoid figures that change quickly.
No content is perfect: if a question seems wrong or ambiguous to you, report it from the quiz. Reports are reviewed and questions are corrected or removed.
