Feedback built on actual research

-adapted from Dr. Ishii’s model of mathematical communication

One consistent rubric -Every time, automatically

  1. Routine

    -The steps they followed

  2. Structure

    -How the explanation flows

  3. Reflection

    -Why each step works

  4. Language

    -Precise math vocabulary

  5. Correctness

    -Is the math right

Capture Thought AI was designed from the ground up with a research-based rubric built in.‍ ‍

No need to recreate the wheel

Teacher reviews and acts

-You verify, add a personal note, and share directly with the student.

Screenshot of an online assessment showing an overall suggested score of 8.5 out of 10, labeled 'Excellent'. There is a note explaining that Lucy provided a clear explanation but made a minor verbal calculation error, and her written work was correct. A blue information box states that the score considers the quality of the explanation as a whole. A green box confirms the explanation is likely authentic.

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.

Screenshot of an AI assessment dashboard showing an overall score of 9.0 out of 10, with feedback on a student's explanation of finding the inverse of a function, and a trustworthiness indicator of 'Likely Authentic' with a caution flag for high explanation score.

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.
