Retriv is the flashcard app you talk to. It reads each question out loud, you say the answer, and it tells you right away whether you got it — like studying with a tutor instead of flipping through a stack of cards. Hands free and eyes free, so you can review while walking, cooking, or getting ready in the morning. WHAT MAKES IT DIFFERENT • Answer out loud. Real voice grading that accepts how people actually talk — say "fifty six" or "56" and both count. • The Recap Round. Miss a question and it comes back at the end. Write it out, type the answer, then say it aloud. The celebration only unlocks once every miss is verified. • AI Smart Scan. Photograph a page of notes or a textbook and get a ready-to-study lesson in seconds. • Spaced repetition. Cards come back right before you would forget them, so your review time goes where it is actually needed. • Highlight to build. Drag a finger across a question and answer in a photo to turn it into a card. FOR TEACHERS AND STUDENTS Create a class, hand out a 6-character code, and every student who joins gets your lessons automatically — nothing for them to set up. • Post announcements the whole class sees • Share lessons that appear on every student's device • See who has finished the work and who has not, lesson by lesson • Students' personal study stays private.
