Can you tell if a student used AI to write this? Two ways we can.
-two signals that cross-check each other, built into every submission
We listen to how they said it
-Natural hesitations, self-corrections, and genuine phrasing are detected directly from the video — a scripted or AI-written answer doesn't sound like a kid thinking out loud in real time.
When the two don’t line up, we tell you
-A video can sound confident. A reflection can miss the point. On their own, either one could be a fluke. Together, a mismatch is hard to fake — because it means passing two independent tests, not performing for one.
We ask them to reflect — before they see their score
-With Reflection Mode enabled, we don't ask a generic question — we ask a question built from their own explanation, before they ever see their score. Answering it well means actually understanding what they said
Most tools can tell you whether an answer sounds right. This tells you whether the student actually knows why.
