SifuSays

SifuSays turns curiosity into real knowledge, one short video at a time.

Swipe through Shorts, each about one surprising fact: how long a new habit really takes to form, how a $35 drawing became Nike's logo, or the quick rule that tells you when your money doubles. Every fact comes from a real source, such as a study, a book or an official body, and you can open that source yourself.

WHAT YOU CAN DO

• Watch Shorts: under a minute each, with captions you can follow.

• Go deeper: tap "There's more to the story" to see the facts, charts and numbers behind any Short.

• Ask Sifu: an AI mentor that answers your follow-up questions and shows where each answer came from.

• Explore 8 topics: psychology, business, money, health, history, sport, tech and AI.

• Track your progress and keep a daily streak, with an optional daily reminder.

• Choose light or dark.

HOW SIFU ANSWERS

Sifu answers from the material in the app first, and says so when an answer is general knowledge instead. Sifu's answers are written by an AI model and can be wrong, so check the linked source when it matters.
