Marking worksheets you didn't generate

Feature D · 5 min read

Every Singapore parent has a stack of assessment books somewhere. Tuition-centre worksheets. School topicals. That one popular assessment book everyone in the cohort is working through. The material is good — what's missing is time to sit and mark it all.

So the app doesn't limit itself to its own questions. If the page is in front of you, it can mark it.

What you can upload

• Printed worksheets with handwritten answers. Photograph the page after the child has done it.
• Pages from an assessment book. Snapshot the page, the AI reads the questions, reads the answers written on it, marks the lot.
• School handouts and topical worksheets. Same flow — photograph, upload, get feedback.
• Pages from past-year practice books. Useful for self-testing before a real exam.

How the flow works

1. Photograph the page. On the phone, in good light, the page flat. The app guides you on framing.
2. Upload. The image goes to the AI, which reads the questions and the student's answers.
3. Marking. Each answer is scored using the same rubric the app uses for its own generated questions — Singapore syllabus, SEAB-style marks.
4. Feedback. Score per question, what's strong, what's missed, a model answer for the open-ended ones.

Why this matters

The honest truth is that most of a Singapore student's practice still comes from books, not apps. Books are familiar, schools hand them out, and parents know which ones to buy. An app that ignores those is an app that only gets opened occasionally.

By marking whatever's in front of the child — generated, uploaded, or handwritten — Professor Turtle fits into the existing routine instead of trying to replace it.

The pain points this closes

Three things, mostly:

• Workload for parents. Marking a stack of assessment book pages on a Saturday afternoon isn't anyone's favourite job. The app does it in minutes.
• Feedback delay. The longer the wait between "do the work" and "see the mistakes", the less the child remembers about why they answered the way they did. Same-day feedback is the difference between learning and forgetting.
• Wherever you are. Photographing a page and getting it marked on the phone means marking happens on the MRT, in the car, at the dining table. The work doesn't pile up at the kitchen counter any more.

On the go

This is the most phone-friendly feature in the app. Camera, upload, results — all in one sitting of a few minutes. No printer, no scanner, no laptop. A child finishes a page in the back seat, photographs it, and has the feedback by the time you've parked.
