Vizia is a free online tool that allows users to create video-based quizzes by importing videos from YouTube or Wistia and adding multiple choice, short answer, poll, or call-to-action questions along the video timeline. Responses to the questions are collected in a spreadsheet that can be downloaded or opened in Google Sheets. Users create a Vizia account, upload a video, add questions, and have the option to require viewers to provide their name and email before viewing or make the first question a name prompt.
