QANDA
AI homework solver that scans math and science problems with your phone camera
QANDA is a practical pick for students who want quick, photo-based solutions across multiple subjects. The free tier's daily question cap can feel limiting for heavy users, but the premium tier offers unlimited queries if you need them. For exam prep and homework, it's more versatile than pure math solvers, though deeper conceptual learning may still benefit from human guidance.

The free tier limits you to a set number of questions per day; hitting the cap means waiting 24 hours or paying for more.

About QANDA
QANDA is an AI-powered homework solver designed for K-12 and university students tackling math, science, and other subjects. It started as a photo-based math solver and has grown into a conversational study assistant that answers typed and voice questions too. With over 95 million students worldwide and billions of questions answered, QANDA has built a reputation as a reliable companion for quick academic help. The platform is mobile-first, with iOS and Android apps, but you can also use it from your browser on the web. Key features include photo-based problem solving, chat-based question answering, step-by-step explanations, learning history tracking, personalized recommendations, and multi-language support. The chat interface makes it interactive — you can ask follow-up questions, not just upload images. This conversational layer sets QANDA apart from older, image-only solvers. QANDA is built by Mathpresso, a South Korean edtech company, and uses computer vision for problem recognition and natural language processing for conversational queries. It covers a broad range of subjects beyond math, including science and other academic areas, making it useful for a wider audience than pure math solvers. The free tier gives you a set number of questions per day, which is enough for many students, and a premium subscription removes those limits for heavier users. Compared to alternatives like Photomath or Socratic, QANDA offers broader subject coverage and a more conversational interface. If you're a high school student stuck on calculus or a college student double-checking physics problems, QANDA aims to reduce friction and make studying more efficient.
Behind the Verdict
When you're in a bind at 11 PM with a calculus problem you can't parse, QANDA earns its keep. Snap a photo, get a step-by-step solution, and move on. That's the core use case, and it's what the tool was built for. For everyday homework and quick verification, it beats digging through generic search results or waiting for a friend to reply. Where QANDA really stretches beyond competitors like Photomath is the breadth of subjects it handles. It's not just math — science and other academic areas are in scope, which makes it a more versatile companion if you're juggling multiple classes. The chat-based follow-up lets you dig into a solution rather than being stuck with a single image answer, which is a genuine upgrade over older solvers. The catch? The free tier's daily question limit can run out fast, especially if you're solving problem sets in bulk. When that hits, you're either waiting for the next day or paying up for premium to remove the cap. For students on a tight budget, that's a real consideration. You can get a lot out of the free version, but power users will feel the squeeze. If your goal is deep conceptual understanding rather than getting unstuck, QANDA isn't a substitute for a tutor or a good textbook. The step-by-step explanations are designed to help you follow the logic, but they don't replace the back-and-forth of a live human who can adapt to your gaps. Think of it as a bridge — it gets you over the hurdle, but it doesn't do the learning for you. For the price of entry (free), it's hard to argue with having QANDA on your phone. Compared to buying a tutor or a premium solver subscription, the free tier already covers a lot of ground. If you hit the daily cap regularly and find yourself relying on it, a premium sub is a reasonable unlock, but start
