What Is Socratic by Google?
Socratic by Google is a free AI-powered homework help app that lets students photograph a question and receive a detailed step-by-step explanation. Unlike Photomath which focuses purely on math, Socratic covers science, history, English, social studies, and more — making it the most broadly useful photograph-based homework help tool available. The AI identifies the question, finds the most relevant educational content, and provides a clear explanation with diagrams, definitions, and worked examples. It is a student-facing tool — teachers benefit by recommending it as an independent study resource, and by understanding how students use it when thinking about assignment design.

Our Verdict
Recommended as Student Homework Support Tool
Socratic is one of the best free homework help tools available and the broadest in subject coverage. Recommend it to students as a 'stuck at home' resource. Design your assignments to require process and reflection (not just final answers) to prevent copying, and discuss with students how to use it as a learning tool.
