Hypersay is an audience engagement tool built for those who teach, deliver lectures, hold meetings, do workshops or speak at conferences. The idea is simple: just upload your powerpoint, share the unique session code with your audience, add interactions (live quizzes, ask questions, share videos) and boom! now you are live. Think live slide sharing, private note-taking and other goodies. Best part? You keep a good degree of control over your audience: know when they are not paying attention, add polls on the fly, have all data saved. Hypersay is currently in beta trial with several universities, schools, event organisers and other companies. Would love to see what YOU can do with it!
