How it works
Ask → understand → practice → remember. In your language, on your phone.
- Step 1Ask
Snap a problem, type a question, or ask out loud — in any language.
- Step 2Understand
Sugar explains it your way: direct, Socratic hints, or Feynman-style.
- Step 3Practice
Turn the explanation into a quick quiz or flashcards, so you use it instead of copying it.
- Step 4Remember
Sugar keeps what you got wrong and brings it back before the test.
