QuestionAI Review 2026: Pricing, Features and Verdict
This review is researched from each provider's official pricing, plans and public user feedback — see our editorial process for how we keep it accurate.
Is QuestionAI worth using for homework help?
QuestionAI is a free-to-download chatbot app (iOS, Android, web) that answers homework questions from a typed prompt, a photo, or an uploaded PDF, covering math, biology, history, social science, English, and business. It's a reasonable pick if you want a quick, no-setup answer to a single question on your phone — it's a weaker choice if you want structured study materials like flashcards, quizzes, or organized lecture notes, since that's not what it's built for.

| Standout feature | Photo-to-answer: snap a picture of a math problem (or any question) and get a worked answer in seconds |
What QuestionAI actually is
QuestionAI is built by FlowMind Technology Inc., a Delaware-registered company, with the mobile app itself listed on the App Store under publisher D3 Dimension Technology Pte. Ltd. — a common setup where a regional entity handles app-store distribution for a product marketed under a different company name. The product is reachable at questionai.com and through iOS/Android apps branded "Question.AI - Math Calculator" and similar names.
Unlike a lot of AI study tools that stay quiet about their underlying model, QuestionAI's own App Store listing states its answers are "powered by DeepSeek V3." That's a specific, checkable claim from the vendor, though as with any AI model claim, treat it as what the vendor states rather than something independently verified against the app's live responses.
The core interaction is simple: type a question, upload a PDF, or take a photo of a printed or handwritten problem, and the app returns a text answer with (for math and science problems) a step-by-step breakdown. There's also a basic chat mode for general questions, a calculator, and a translation feature the app describes as supporting 140+ languages — useful if it's also used as a general-purpose assistant rather than strictly for schoolwork.
Pricing
QuestionAI doesn't publish a public pricing page the way most SaaS tools do. Its own Terms of Use state only that "Plus services are available in monthly or yearly plan with multiple service level choices" and that actual prices are shown on "the value-added Services and in-app purchase page" — meaning the number you'll actually pay only appears once you hit a paywall inside the app itself, not on questionai.com.
| Plan | Price | What's included |
|---|---|---|
| Free | $0 | Limited number of questions per day, photo scanning, basic chat |
| Plus (monthly) | Not published on the marketing site — shown at in-app checkout | Vendor states higher/unlimited daily question limits and priority answer speed |
| Plus (yearly) | Not published on the marketing site — shown at in-app checkout | Same Plus features billed annually, typically at a lower effective monthly rate for this style of app |
Refunds are handled under a stated 14-day window from the transaction date, and subscriptions renew automatically until cancelled at the end of the current billing period — standard app-store terms, nothing unusual to QuestionAI specifically.
Because the exact Plus price isn't disclosed publicly, don't take any third-party figure you see quoted elsewhere as current — check the in-app purchase screen for your region before subscribing. Pricing, free-tier limits, and feature availability here were accurate as of this post's publish date (2026-09-18) and can change quickly, since subscription apps frequently adjust prices by region and promotion.
Features walkthrough
Photo-to-answer scanning. Point your phone camera at a printed or handwritten question — a math problem, a multiple-choice item, a short-answer prompt — and QuestionAI returns a typed answer, usually with a worked-through explanation for math and science. This is the feature the app is built around, and it works without needing to retype anything.
PDF upload. You can upload a PDF (a worksheet, a reading, a problem set) instead of scanning page by page, which is faster for longer documents but works best when the PDF is a clean digital file rather than a scanned image with poor contrast.
Multi-subject coverage. QuestionAI's own site lists math, biology, history, social science, English, and business as covered subjects. That's a broad net for general homework help, though it also means no single subject gets specialized tooling (there's no dedicated citation manager for English essays, or graphing tool for advanced math, the way a subject-specific app might offer).
General chat mode. Beyond scanned homework questions, the app doubles as a general AI chatbot for open-ended questions, which is useful if a student wants one app for both "explain this equation" and "explain this historical event in a sentence," but it also means the product's focus is split between "homework solver" and "general assistant" rather than being purpose-built for one.
Built-in translation. The app advertises translation across 140+ languages, aimed at non-native English speakers working through English-language coursework or communicating across language barriers generally — a feature most single-purpose homework apps don't bother with.
Who it's actually for
- A student who needs a quick answer to one question right now (a tricky algebra problem, a vocabulary definition, a quick fact-check) is the clearest fit — snap a photo, get an answer, move on.
- A student juggling coursework in a non-native language benefits from the translation layer more than a homework tool with no language features at all.
- A student who wants organized study materials — flashcards from a full lecture, spaced-repetition review, or auto-summarized notes — is better served by a tool built around that workflow (see the comparison below), since QuestionAI is optimized for one-off Q&A rather than ongoing review.
- A teacher or parent evaluating academic-integrity risk should know this app, like any instant-answer homework tool, can be used to bypass genuine problem-solving rather than support learning it.
Pros and cons
| Pros | Cons |
|---|---|
| Fast, simple photo-to-answer flow with no setup | No public pricing page — exact Plus cost only shown at in-app checkout |
| Names its underlying model (DeepSeek V3) rather than staying vague | No structured study tools like flashcards, spaced repetition, or lecture-to-notes conversion |
| Broad subject coverage (math, biology, history, social science, English, business) | Broad-but-shallow coverage means no subject gets specialized depth |
| Built-in translation across 140+ languages | Encourages one-off answer-getting over building understanding, which can hurt retention if used as a shortcut |
| Free tier available with no signup friction for a first try | Auto-renewing subscription model — easy to forget to cancel if you don't track the billing date |
Integrations and ecosystem
QuestionAI is a standalone consumer app, not a platform with a developer ecosystem. There's no public API, no Zapier/Slack integration, and no LMS (Canvas, Google Classroom) integration documented on its site or app-store listings — fine for individual student use, but not something a school or tutoring service could wire into existing tools.
Where it's a strong fit
QuestionAI earns its place for the narrow but common case of "I have one question right now and want an answer fast." The photo-scan flow removes the friction of retyping a problem, subject coverage is broad enough for most K-12 and intro-college coursework, and naming its model (DeepSeek V3) is more transparency than many competitors offer. The free tier is also usable for occasional questions rather than a locked demo.
Where to think twice
Skip QuestionAI if you need real study-material generation — flashcards from a textbook chapter, spaced-repetition quizzes, or auto-generated lecture notes with timestamps — since that's simply not what this app does; a note-taking-first tool built for that workflow will serve you better. Also think twice if not knowing the exact subscription price until you're at the in-app paywall bothers you; most competitors publish a pricing page up front, and QuestionAI currently doesn't. And if you're a parent, teacher, or school weighing academic-integrity concerns, know that an instant photo-to-answer tool is easy to lean on as a shortcut rather than a learning aid — a real limitation of the category, not unique to QuestionAI, but worth factoring in before recommending it to a student.
How QuestionAI compares to other AI study tools
QuestionAI is closest in spirit to Mindko — both are instant-answer tools for one question at a time, scanned or typed, rather than tools that generate ongoing study material. The practical difference: Mindko runs as a Chrome extension with a stated $19.99/month price after a 3-day trial, while QuestionAI is a mobile-first camera-scan app with a free daily-question tier and Plus pricing revealed only at in-app checkout.
If the actual goal is turning a recorded lecture, slide deck, or long PDF into organized notes, flashcards, and quizzes for ongoing review, TurboLearn AI and YouLearn AI are built for that workflow specifically and will do it better than any instant-answer app — they're solving a different problem (studying over time) than answering one question right now.
Bottom line
QuestionAI does one thing — answer a single homework question from a photo, a typed prompt, or a PDF — and does it with a low-friction free tier and a model claim (DeepSeek V3) it's willing to name. It's a sensible app for quick answers, but it's not a study-management tool, doesn't publish Plus pricing up front, and won't replace a note-taking or flashcard-focused app if that's what you actually need. Treat it as a fast lookup tool, not a study system.
Frequently asked questions
Is QuestionAI free to use?
There's a free tier with a limited number of questions per day. A paid "Plus" tier removes some limits, but its exact price shows only at in-app checkout, not on the marketing site.
What AI model does QuestionAI use?
Its App Store listing states answers are powered by DeepSeek V3 — the vendor's own claim, not independently verified here.
Does QuestionAI work for subjects beyond math?
Yes — math, biology, history, social science, English, and business, plus a general chat mode for other questions.
Can QuestionAI read a PDF instead of just photos?
Yes, you can upload a PDF directly instead of photographing each page; it works best with clean digital PDFs rather than low-contrast scans.
How does QuestionAI handle refunds?
Its policy states refund requests must be submitted within 14 calendar days of the transaction date, reviewed under the policy and the payment provider's rules.
Is QuestionAI good for building long-term study habits, like flashcards or spaced repetition?
Not really — it's built for one-off answers, not ongoing review. A tool built around notes and flashcards, like TurboLearn AI or YouLearn AI, fits that need better.
Who makes QuestionAI?
FlowMind Technology Inc. operates questionai.com; the mobile app is listed under D3 Dimension Technology Pte. Ltd., a common app-store distribution arrangement.
Is QuestionAI easy for a first-time user?
Yes — no account setup is required to try the free tier, and the core flow (photo or text in, answer out) has no real learning curve.
