Project any problem — your slides, a worksheet, a past exam — circle it live, and Margin poses the guiding question while you walk the room. It gives hints, never answers, so the thinking stays with your students.

The whole class sees this. Try the buttons — hints escalate, and steps reveal only when the teacher clicks.
Try u = x. Then du = dx, and dv = eˣ dx gives v = eˣ. What does uv − ∫v du become?
Votes are anonymous — you see counts, never names. Switch to a student’s seat and vote to watch these numbers move.
On the projector now
Tap one — it reaches your teacher as a count, never your name.
Project the warm-up, circle it, and put Margin's guiding question on the board while you take attendance. Students argue about the approach — not copy an answer.
Instead of revealing your full solution, let Margin point at the next step and ask the class to predict it. "Reveal one step" keeps the pace in your hands.
During independent work, a stuck student circles their own problem and gets a nudge in your course's notation — while you help the student who needs you most.
Circle a finished solution with a planted mistake and ask Margin to point near — not at — the error. First table to find it explains it to the class.
Load your syllabus, slides, and textbook chapters. Margin explains with your notation, your methods, your vocabulary — so it reinforces your teaching instead of contradicting it.
Run review sessions on past exams knowing Margin won't blurt the final answer on the projector. The full solution needs a deliberate click — yours.
Run a session and every student works the problem set on their own Mac, at their own pace, with their own hints-only tutor. You see the room the way you wish you always could: who's cruising, who's leaning on hints, and who needs you next — ranked, live.
This is live in beta — start a class now.
Picked u = eˣ, and Margin nudged her to compare d/dx of each factor — no retry in 2 minutes. Confidence rated low before attempting.
Three rapid submissions with different answers — looks like guessing, not reasoning. Margin switched to a prerequisite check on basic antiderivatives.
Needed one hint to set up ∫ u dv, now progressing steadily on their own.
No hints all session. Third week in a row trending more independent.
Finished in 9 minutes. Margin offered the transfer problem (same concept, different surface) to keep her busy.
Progress signals only — you see how each student is doing, never their screen.
Evaluate the integral:
Each student's tutor follows your class rules — and "Request teacher help" pings you, not the AI.
Students enroll once in the Mac or Windows app. Homework, tests, course context, and live sessions arrive in Student Home without another class-period setup ritual.
Keynote, PowerPoint, PDFs, Google Slides in a browser, Desmos, an IDE — if it's on your screen, you can circle it. Your existing materials are the content.
Local mode runs the entire tutor on the Mac itself — no cloud calls, nothing leaves the building. Course files are processed on-device either way.
Pedagogy stays yours. Margin's defaults are deliberately conservative: identify the problem type, point at the key step, ask one guiding question, stop. It's designed after the research on effective tutoring — guide, don't tell — and the full solution is always behind an explicit click that you control in class.
Private suggestions mid-lesson: the next guiding question, a simpler analogy, a check for the misconception it spotted — visible only to you, used only if you want.
Topics covered, misconceptions observed, what explanation finally worked — structured session notes you approve, not an hour of video to scrub through.
What the student practiced since last time, where they slipped, and a suggested agenda — so the session starts at minute zero, not minute fifteen.
A demo takes fifteen minutes: bring one of your own worksheets or slide decks and we'll run it live. Pilot classrooms use Margin free, and we build around your feedback.
