Read all FAQs
How does Tutor Wong help parents check homework?

Tutor Wong 補習天王 is an AI homework helper for Hong Kong families. Photograph homework or a worksheet to review marking and feedback for each question. Guided hints, step-by-step explanations and targeted practice help children work through topics they need to revisit. Parents can use it alongside schoolwork or tutoring.

Will my child see the full answer as soon as they open it?

Guided mode starts with hints and encourages your child to try. Step-by-step solutions and follow-up questions are also available when they need more explanation. Different modes suit different learning needs.

Can it check primary and secondary Chinese, English and maths homework?

The app supports learning profiles from kindergarten through primary school to S6, with subjects including Chinese, English, maths, science and humanities. Available subjects and marking guidance vary by year group. Include clear, complete questions and answers in your photos so the app can read them.

How can an AI tutor support learning between tutoring lessons?

With Tutor Wong, children can photograph completed homework, review feedback question by question and note what they still need to ask their teacher or tutor. Guided hints, step-by-step explanations and targeted practice help them revisit what they learnt between lessons.

How can we use Tutor Wong when preparing for TSA or HKDSE?

Photo homework checking and step-by-step explanations can support everyday written practice during TSA or DSE revision. Select the relevant year group and subject, then check feedback against the marking guidance from your teacher or practice paper. AI feedback is not an official TSA or DSE assessment and cannot predict exam levels.

Can we check homework from photos for free?

Yes. The free plan includes 20 homework checks per month, up to 2 a day, plus limited step-by-step solutions and AI Tutor sessions. Paid plans add worksheets, learning reports and more usage. See the pricing page for the full allowances.

Should parents review AI homework checking results?

Yes. AI can misread handwriting, images or the meaning of a question, so parents should review marking and explanations. If something looks unclear, compare it with the original question, the school’s answer guide or ask a teacher. AI feedback can support learning but does not replace a teacher’s judgement.
