Three tools our teachers built and use in class, right now.
Students draw their working, an AI tutor nudges them toward the answer with a question instead of giving it away, and teachers have the final say on every mark.
Sign in with your school Google account (@moe.edu.sg / @students.edu.sg).
Students get a question back instead of the answer, and work toward it hint by hint.
Every correct step earns marks (M / A), so good working counts even when the final answer slips.
AI feedback is only a draft. Teachers award or withhold any step and override the verdict anytime.
Record, transcribe, and grade oral responses in English, Chinese and Malay with AI — aligned to SEAB rubrics.
Record oral responses directly in the browser — no app install needed.
Automatic English and Mandarin speech-to-text powered by Gemini and Claude.
SEAB rubric-based scoring with detailed feedback via Claude.
