AR Book is a Ukrainian educational platform that helps teachers transform ordinary lessons into engaging and innovative sessions. We combine learning materials with augmented and virtual reality (AR/VR) technologies, interactive 3D models, experiments, games, and exercises that truly engage students in the learning process. AR Book provides teachers with ready-made materials, significantly saving time on lesson preparation. With deep analytics, educators receive detailed data on students' performance, allowing them to adapt the learning process for each student and improve their results.
