For university STEM instructors

Classroom polling for large STEM lectures

Photograph a slide, and the AI Assistant drafts a question with a wrong answer for each common mistake. Students answer on their own devices, with no app and no account, and the report shows which mistakes the room made.

Start freeSee a sample report

From your slide to a ready question

Describe what you want, paste your notes, or attach your slides, your outline or a photo of the board. The AI Assistant drafts the question beside your lecture, and nothing changes until you apply it.

Wrong answers from real mistakes
Each wrong option names the mistake that leads to it, so the report can tell you which one your class made.
Equations, graphs and molecules that display
Every formula, graph, diagram and molecule it writes is drawn and checked before you see it.
Never in front of the class
It never appears on the projector or on a student's device, and reports use no AI.
Included
Pro includes it, and so does the free plan with a university sign-in.

Equations, graphs, molecules and code, on every device

Write the source you already use, or ask the AI Assistant to write it, and each student's device draws it. If a device can't, it shows the source, so no one sees a blank. Photos of a board or a slide work too.

How it works

  1. 1

    Write the questions

    Ask the AI Assistant to draft them from a description, your notes or a photo of a slide, or write them yourself.

  2. 2

    Ask them in class

    Students scan the code, answer on their own device and say how sure they are. You see the results before the room does.

  3. 3

    Read the report

    It is ready the moment you end the session.

Every wrong answer has a reason

The report shows how many students chose each wrong answer, and how sure they were.

Session report · Sep 21, 2026

On question 1, 47% of the answers were correct. 38% chose “Zero” (thinks the ball stops at the top), and 61% of them were confident.

Question 1: confidence and correctness

31%
Right and confident
16%
Right but unsure
29%
Wrong and confident
24%
Wrong but unsure

Unsure includes guessing.

Sure and wrong
Confidence is set against correctness, so a guess and a misconception look different.
The same question, next year
Ask it again, and both runs appear side by side, each with its date.
Questions that need work
Ask the AI Assistant which questions need work, and it reads your results to tell you.
One result as an image
Export any question's result for the first slide of your next lecture.

Anonymous by design

Students never sign in, and nothing we keep identifies them. For each question, we keep only figures for the whole room. The AI Assistant never receives anything about a student, and we don't keep your conversations with it.

Questions

What if the lecture runs over?
End whenever you need to. Next time, the lecture picks up at the first question you didn't ask.
Do I have to use the AI Assistant?
No. Every part of Tapsity works without it, and reports never use AI.
What does the AI Assistant see?
What you write or attach, your course, and a question's result from a session only if at least 5 devices answered it in that session. It never receives your name, your email or anything about a student.
Can it take attendance?
No. By design, Tapsity can't tell who answered.
Is it only for STEM?
It is built for large STEM lectures, and works just as well in any subject.
