NOTABR

NOTABR とは？

NOTABR turns studying into a weekly competition. Pick a subject - maths, physics, history, English and more - and you land in a league division, Bronze up to Legend. Answer AI-generated multiple-choice quizzes, earn points for accuracy and speed, and every Monday the top 7 of your division are promoted while the bottom 5 drop. Each question is independently re-solved by an AI and discarded if the answer key is wrong or ambiguous. Free plan, no card needed. In Portuguese and English.
