Socratic by Google provides resources from the web when students take a photo of a question or use voice input. It identifies underlying concepts in the question to surface relevant videos, explanations, and online materials. For textbook content or handouts, users photograph pages to access alternative explanations. Subject guides cover over 1,000 high school and higher education topics with key points and deeper web resources. Algorithms analyze questions to break down concepts into smaller lessons.
