Built from 4 years of research with 300+ reluctant readers, now used by 80,000+ readers

Created by Elliott Hedman (PhD, MIT Media Lab), Wonder Stories were developed using emotional sensors and eye-tracking technology at Boys & Girls Clubs and Title 1 schools. The research found that questions are the strongest engagement point in reading — so every Wonder Story is built around inquiry-based reading.
