How to Use QANDA in 2026: Step-by-Step Guide
AI-powered math and science homework helper from Korean edtech company Mathpresso — photograph a problem and get step-by-step solutions in seconds, drawing on a database of 10M+ problems and used by 95M+ students worldwide.
QANDA turns a phone camera into a homework tutor: point it at a math or science problem and get a step-by-step worked solution, not just a final answer.
Core Capabilities
Photo-to-Solution Snap a picture of a handwritten or printed problem and receive an instant, step-by-step breakdown covering math and science subjects.
Follow-Up Chat Ask clarifying questions about a solution conversationally rather than re-scanning the problem.
Exam & Curriculum Coverage Includes past exam and mock-test question banks alongside a broader learning-content library, extending beyond single-problem lookup.
Positioning
Distinguishes itself from single-subject calculator apps (Photomath, Mathway, both already in this catalog) through scale — 98M+ generated answers and a global, Asia-rooted user base — and by covering science alongside math rather than math alone.
Pricing
Freemium — the core snap-and-solve flow is free; QANDA Premium unlocks ad-free and expanded features, priced regionally from roughly $7.50/month equivalent.

Create Your Account

Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. QANDA supports photo-problem-solving, step-by-step-solutions, science-qa, exam-prep, homework-chat — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show QANDA what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
