The class mastery heatmap — best check score per unit, gold star at 90%+. (Shown with sample data.)
Every student gets the same patient one-on-one tutor — and you get the classroom view: who's mastered what, who needs help, and where the whole class is stuck.
69 seconds: what your classroom looks like in Mr. Cadabra's Classroom.
The class mastery heatmap — best check score per unit, gold star at 90%+. (Shown with sample data.)
Add students to a class with their login codes — no student emails, no new personal data collected. Works for a family of three or a class of thirty.
Cell colors come from real scored checks, not participation points. "Needs attention" surfaces the unit your class is actually weakest on.
Click any student for their full dashboard: units, accuracy, streak, and honest time-on-task (idle time doesn't count).
A voluntary, friendly assessment maps each student's strengths and recommends a path — foundation gaps first.
A 9th grader can quietly work in Pre-Algebra fractions without ever seeing a grade level on screen — built for intervention without stigma.
Students talk with Mr. Cadabra through a headset mic — speech is transcribed and the audio deleted immediately, never stored. Quiet classroom? Students can type instead.
Every Friday, one email with a summary for each student in your class: their real minutes, what they mastered, where they're stuck, and who needs you most this week. The Monday-morning picture, delivered before Monday. Included with classroom plans at launch.

The mastery heatmap: every student against every unit, colored by their best real quiz score, gold star at 90%+. "Needs attention" surfaces the unit the class is weakest on, and clicking any student opens their full dashboard — units, accuracy, streak, honest time.
No. Adult views are read-only by design. Every number comes from a quiz the student actually took, which is exactly what makes the heatmap worth trusting.
No. Headset mics make it a real conversation, but typing works everywhere — including a silent classroom — and the youngest students say their answers or tap big answer buttons.
This term we're running free pilots with a limited number of classrooms, co-ops, and microschools — you get the product, we get honest feedback. Email support@mrcadabra.com and tell us about your class.
It was built for exactly that: no grade level ever appears on the student's screen, so a 9th grader can quietly rebuild Pre-Algebra fractions without stigma while the rest of the class works elsewhere.
A first name or nickname and a code — that's it. No student emails, phones, or photos. When students talk with the tutor, speech is transcribed and the audio is deleted immediately, never stored. Nothing is sold and there are no ads.
Yes — the class view works the same for three students or thirty, and setup is minutes, not meetings. Mixed ages and mixed courses in one roster are exactly what it's for.
