Socratic
FreeGoogle's completely free homework helper that uses photos to find explanations and educational resources
What is Socratic?
Socratic by Google is one of the few truly free AI homework helpers on the market. Acquired by Google in 2018 and integrated into the broader Google app and Google Lens ecosystem, Socratic lets students take a photo of a homework problem and get instant explanations drawn from Google's curated educational content — covering Algebra, Geometry, Trigonometry, Biology, Chemistry, Physics, History, Literature, and more. Unlike AI chatbots that generate potentially unreliable answers, Socratic pairs AI with curated educational resources (videos, articles, examples) so students see vetted content explaining concepts rather than just a chat response. Because it is a Google product, Socratic has no subscriptions, no premium tiers, no ads, and no hidden fees — it is completely free forever. The tradeoff is that Socratic is less feature-rich than paid competitors: no live tutoring chat, no flashcard generation, no essay writer. It is laser-focused on 'take a photo of a problem, get an explanation with learning resources.' For middle school and high school students doing homework, that is often exactly what they need. Socratic is available as a standalone iOS and Android app and integrated into the Google Lens app. The standalone iOS app is no longer being actively developed per recent reports, but the core functionality lives on through Google Lens integration.

FAQ
Is Socratic really free?
Yes, Socratic by Google is completely free with no subscriptions, premium tiers, ads, or in-app purchases. Google acquired Socratic in 2018 and has maintained it as a free educational tool. All features — photo homework help, curated content, video explanations, and multi-subject support — are available at no cost. This makes Socratic one of the only truly free AI homework helpers on the market.
How does Socratic work?
You open the Socratic app or Google Lens, take a photo of a homework problem, and Socratic uses Google's AI to identify the problem and return relevant explanations, video tutorials, and educational resources from curated partners. Unlike AI chatbots that generate answers, Socratic shows you vetted content that explains the underlying concept, helping you actually learn.
What subjects does Socratic cover?
Socratic covers Algebra, Geometry, Trigonometry, Biology, Chemistry, Physics, History, and Literature at the high school level. It works best for standard secondary school curriculum in these subjects. For college-level specialized content, Socratic is less comprehensive and students may get better results from ChatGPT or dedicated tools.
Is Socratic still available?
Yes, Socratic continues to be available through the standalone iOS and Android apps plus integration with Google Lens. Reports suggest Google is shifting Socratic functionality into the broader Google Lens app rather than actively developing the standalone iOS app, but the core features remain available through both paths. Android users continue to get regular updates.
Socratic vs Photomath for math?
Both handle photo-based math help. Photomath specializes in step-by-step solutions for math problems specifically, with strong handwriting recognition. Socratic is broader (covers all subjects, not just math) but less detailed on math-specific step-by-step work. For pure math homework, Photomath is better. For multi-subject help, Socratic wins.
Is Socratic safe for kids?
Socratic is generally considered safe for middle school and high school students. As a Google product, it follows Google's standard child safety practices and privacy policies. It is ad-free, has no in-app purchases, and surfaces curated content from trusted educational partners. For younger children, parental supervision is still recommended, but Socratic is safer than free-form AI chatbots.
