AI Quiz Maker & Test - Odabi

Odabi is an AI quiz maker that turns your paper workbook into a digital quiz. Snap a photo or upload a PDF, and AI builds a practice test you can solve question by question, with instant grading and an automatic review of every mistake.

Stop copying questions out by hand. Photograph a workbook page or an exam sheet, and Odabi pulls out the questions, answer choices and answers for you. Then solve them one at a time, see your score right away, and let the app collect everything you got wrong into a review note.
