What Is Question AI?
Question AI is a mobile and web application built for students who need help with homework. The app’s primary interface is simple: point your camera at a problem, and the AI returns a solution with explanations.
The product launched in May 2023 under Zuoyebang, a major Chinese education technology company. Its overseas operations run through D3 Dimension Technology, a Singapore-registered entity . The app found traction quickly, reaching the top of US App Store education charts by early 2024.
Question AI is not a general-purpose chatbot. It is purpose-built for academic tasks, with dedicated handling for math equations, science problems, and written assignments. The app also offers a summarizer, writing assistance, and a Chrome extension for desktop use .
How Question AI Works
The workflow is designed for speed and low friction.
Step 1: Capture the question. Users take a photo of a textbook problem, upload a screenshot, or type the question directly. The app supports handwritten equations and printed text.
Step 2: AI processes the input. Question AI uses multimodal models to recognize the problem type and generate a solution. For math, this includes step-by-step derivations rather than just final answers.
Step 3: Review the explanation. The app presents the solution with intermediate steps. Users can ask follow-up questions about specific parts they do not understand.
Step 4: Access additional tools (paid). Deeper AI tutor explanations, PDF parsing, and certain advanced features require a subscription.
The Chrome extension extends this workflow to desktop browsers, allowing users to capture questions from any webpage or learning management system .
Key Features
Photo-Based Problem Solving
This is the core feature. Users snap a picture of a question and receive an answer within seconds. The app handles math equations, chemistry problems, and text-based questions across multiple subjects .
A reviewer on the Chrome Web Store noted: “can use screenshots really useful” . The visual input method reduces typing friction, especially for complex equations.
Step-by-Step Explanations
Question AI does not just provide final answers. It walks through the reasoning process, which matters for learning rather than copying. The depth of explanation varies by subscription tier.
A Trustpilot reviewer highlighted this: “The thorough explanations from Question AI made the difficult physics ideas easier for me to understand” .
Multi-Subject Coverage
The app supports math, biology, chemistry, physics, history, literature, and social science. It also handles language-related tasks like grammar correction and translation.
This breadth positions Question AI as a general academic assistant rather than a math-only solver.
Chrome Extension
The browser extension brings the same capture-and-solve workflow to desktop. It integrates with Google Forms and learning platforms like Canvas and Blackboard, allowing users to get help without switching tabs .
AI Summarizer
Users can upload PDFs or paste text for summarization. This feature is useful for condensing textbook chapters or lengthy articles into digestible notes.
Pricing: What You Actually Pay
Question AI operates on a freemium model. The basic photo-solving feature is free. Advanced features require a subscription.
| Plan Type | Price Range | What It Includes |
|---|---|---|
| Free | $0 | Basic photo solving, limited daily questions |
| Subscription | $0.49 to $99.99 per item (in-app purchases) | AI tutor explanations, PDF parsing, unlimited access |
Sensor Tower data lists in-app purchase items ranging from $0.49 to $99.99, suggesting multiple subscription tiers or credit packs . The exact pricing structure is not clearly disclosed on the app’s website, which creates evaluation friction.
Important billing concern: A Trustpilot reviewer reported being charged $99.99 for a subscription they did not knowingly purchase. They stated the company initially asked for an order ID to process a refund, then claimed they could not trace the order after receiving it . This is a single complaint, but it signals a need for careful subscription management.
Users should verify what they are signing up for during the free trial or initial purchase. Check the renewal terms before entering payment details.
Accuracy and Reliability
Question AI markets itself as highly accurate. Independent user feedback presents a more mixed picture.
What works well: Straightforward algebra, grammar corrections, and definition-based questions generally produce reliable results. The step-by-step format is genuinely helpful for understanding the logic behind a solution.
Where it struggles: Complex multi-step physics problems and nuanced literary analysis can produce errors. A Screenwise review noted: “When it comes to nuanced literary analysis or multi-step physics problems, it can occasionally trip over its own logic” .
A Chrome Web Store reviewer offered a balanced assessment: “like every other AI, it messes up. Not perfect but way better than others i tried” .
The practical takeaway is straightforward. Treat Question AI as a study aid, not an answer key. Verify important results, especially for high-stakes assignments.
Who Should Use Question AI?
Question AI fits well for:
- Middle and high school students working through homework problems
- Students who need step-by-step explanations rather than just answers
- English language learners who benefit from simplified explanations
- Parents helping children with subjects they have not studied in years
Question AI may not fit for:
- College-level work requiring deep subject expertise
- Students who need guaranteed accuracy for graded assignments
- Anyone uncomfortable with subscription-based billing models
- Users who need help with highly specialized or advanced topics
A Screenwise evaluation noted the app is “best for ages 10 and up,” with the caveat that younger users may lack the discernment to handle AI errors or resist the temptation to skip actual learning .
Privacy and Data Protection
Question AI’s Google Play listing states that the app may collect location data, personal information, and three other categories of data. Data is encrypted in transit, and users can request deletion of their data .
The app shares some data with third parties, according to the listing. The exact nature of these sharing arrangements is not fully detailed in publicly available documentation.
For users in regions with strict privacy regulations, the key question is how long data is retained and whether it is used for model training. Question AI has not publicly disclosed SOC 2 certification or Zero Data Retention policies. GDPR compliance, if applicable, is a legal framework rather than a technical safeguard.
Parents should review the app’s privacy policy before allowing children to use it. The Screenwise review notes that Question AI includes standard AI safety guardrails and a kids’ mode, but no system is perfect .
Question AI vs. Alternatives
| Platform | Target User | Key Strength | Pricing Transparency | Core Limitation |
|---|---|---|---|---|
| Question AI | K-12 students | Photo solving, step-by-step explanations | Low (in-app purchases unclear) | Accuracy issues on complex topics |
| Photomath | Math students | Focused math accuracy | High (clear subscription tiers) | Math only |
| ChatGPT | General users | Versatile, handles any subject | High (free tier, $20/month Plus) | No dedicated photo-solve workflow |
| Khan Academy | Self-directed learners | Free, structured curriculum | High (free) | No instant answer generation |
Photomath remains the stronger choice for pure math accuracy. ChatGPT offers broader capabilities but lacks Question AI’s streamlined capture-and-solve interface. Khan Academy serves a different need entirely: structured learning rather than homework assistance.
The choice depends on what you need. For quick homework help across multiple subjects, Question AI is competitive. For focused math support, Photomath is more reliable.
Common Mistakes When Using Question AI
Skipping the free tier test. Use the free version first to assess accuracy for your specific subjects and grade level. Do not subscribe based on marketing claims alone.
Ignoring billing terms. The Trustpilot complaint about an unexpected $99.99 charge is a warning. Check renewal terms and cancel before the trial ends if you do not intend to continue .
Trusting answers without verification. For high-stakes assignments, verify Question AI’s output against a textbook or another source. The app is a study aid, not an authority.
Using it as a replacement for learning. A Screenwise review captured the risk clearly: “If they use it to automate their education while they play Roblox on another screen, it’s a net negative” .
Overlooking the Chrome extension. Desktop users often miss that Question AI has a browser extension. It integrates with Google Forms and learning platforms, which can be more efficient than switching to a phone.
