QANDA
AI-powered homework solver for math and science, used by 95M+ students.
QANDA is a reliable tool for quick homework help, especially in math. Its photo-based interface and step-by-step solutions are strong, but it may not replace a full tutoring experience for complex topics. If you need instant step-by-step math solutions on the go, QANDA is a solid choice—especially the free tier for light use. For deeper conceptual help or advanced science, consider pairing it with a tutor or a more comprehensive platform like Khan Academy or Chegg.

About QANDA
QANDA is an AI-powered learning platform that helps K-12 and university students solve problems across math, science, and other subjects. Originally known for its photo-based math solver, it now offers a conversational AI assistant that handles a wide range of academic questions. Students can take a photo of a problem or type it in, and QANDA provides step-by-step solutions, explanations, and related study resources. The platform has been adopted by over 95 million students worldwide and claims billions of answered questions over the past decade. QANDA targets students who need quick, reliable homework help. The experience is mobile-first, with dedicated iOS and Android apps, but also accessible via web browser. Beyond solving specific problems, QANDA offers learning features like subject-wide practice, chat history, and personalized recommendations to reinforce understanding. What sets QANDA apart is its AI that goes beyond just answering—it provides detailed step-by-step reasoning, similar to a tutor. The chat-based interface ('ask questions') expands its utility beyond static image uploads, making it interactive. The platform integrates with other study tools and offers a free tier, making it accessible to a broad audience. QANDA is built by Mathpresso, a South Korean edtech company, and is available in multiple languages. It combines computer vision for math problem recognition with natural language processing for conversational queries, aiming to reduce friction in studying and make learning more engaging. Compared to alternatives like Photomath or Socratic, QANDA offers broader subject coverage and a more conversational interface.
Behind the Verdict
QANDA excels at providing fast, accurate step-by-step solutions for math problems through its photo recognition feature. The conversational AI adds flexibility, allowing you to type out questions or follow up. The free tier is generous—daily usage limits still let you solve several problems. The platform's 95M+ user base and billions of solved problems speak to its reliability and reach. However, QANDA is less effective for non-standard notation or complex multi-step problems that require deep reasoning. The free tier's daily limit can be restricting for heavy users. Advanced features like unlimited usage and ad-free experience are locked behind Premium, whose price is unconfirmed. Unlike Photomath, which focuses solely on math, QANDA covers science and other subjects, but the depth in non-math areas is limited. It's not ideal for research-grade tasks or users who need citation-worthy sources. Mobile apps are well-designed, but offline mode is absent. Overall, QANDA is a strong companion for K-12 and early college students, but not a replacement for human tutoring or advanced study tools.
