About Ottiwise

PSLE prep that finds the gap, fixes it, and feels like play.

Why we built it

Ottiwise is made in Singapore by a parent of a primary school child. Like many families, we saw how much of PSLE preparation depends on tuition: someone to find exactly what a child is missing, pick the right next question, mark open-ended work and check in every week.

AI can now do much of that, every day, for every child. Ottiwise is a short daily plan across Maths, Science, English and 华文 that diagnoses gaps at skill level, gives practice that stays PSLE-hard, and marks handwritten working, Science answers, compositions and speaking the way the exam does.

What we believe

Each subject, its own way

Maths is fluency and choosing the right model. Science is fixing misconceptions and writing answers that link concept to set-up. English is patterns, evidence and writing craft. 华文 is building the language every day.

Marked the PSLE way

Method marks for working, concept points for Science answers, bands for compositions, always with the reason shown.

The child fixes it

Hints and nudges come before answers. Every mistake comes back as a fresh question until it is fixed.

Habits over scores

Rewards come from finishing the plan, reviewing and fixing old mistakes. A wrong answer never costs anything.

Accurate and safe

Every question is original. Maths answers are checked by code, and every item passes automated checks before it is used.
We are working with teachers to review questions and AI marking. Anything the AI is unsure of goes to a parent first.
There is no open chatbot. AI gives hints, marks work and runs short speaking and teach-back practice, all limited to the topic.
Parents can see and change every mark.

Ottiwise is in an early pilot. We would love to hear from parents and teachers.
