An AI physics tutor you can watch work
DuckyHelper is an AI physics tutor that shows you why things move the way they do. Ask why a pendulum keeps time and Eddy opens a pendulum you can drag and time yourself. Ask why you feel lighter in an elevator and it works the forces through with real numbers. It explains out loud, draws on the blackboard, and gives hints before answers, in the DuckyHelper Mac app.
Ask why. Then try it.
Physics questions have answers you can test. Two from our films, worked the way the tutor works them.
Why does a pendulum keep time?
Eddy opens a pendulum you can play with. Drag the start angle from 25 degrees down to 10 and one swing there and back barely changes, 2.03 seconds to 2.01. For small swings the time depends on the length of the string, not on how far it swings, which is why a clock can count on it.
Why do you feel lighter in an elevator going down?
The floor pushes up on you less while the elevator speeds up downward. For a 60 kg rider whose weight is 588 newtons, an acceleration of 2 meters per second squared downward means the floor pushes 60 × (9.8 − 2) = 468 newtons: you feel about 80 percent of your weight.
Pull it, let go, read the numbers
Ask how a pendulum, a projectile or a circuit works and you can get a small simulation to play with: drag the ball, move the sliders, and read the numbers as they change. Change one thing at a time and you find the rule yourself, which is the part that sticks.
In the Eddy tab the simulation opens on Eddy's desk while Eddy talks you through it. With Ducky it opens in the pill, next to the homework you are working on.
Ask to graph position or velocity against time and you get a graph you can hover, pan and zoom, with sliders for the letters.
Every force, every step
Ask for a problem step by step and you get 3 to 6 steps, one move each, with the math: draw the forces, write Newton's second law, solve. Ask Eddy to explain it on the blackboard and it writes and draws in time with its voice, then hands you a your turn problem.
Press fn and ask about the problem on your screen. Ducky draws numbered marks on your worksheet for each step, circles the quantity it means, and writes the next line in the margin.
Stuck halfway? Ask for a hint. On a Mac, Hint opens a ladder: a nudge, a bigger hint, the worked step, then the answer if you still want it.

Ask Eddy
Say one of these out loud. Eddy picks how to show it: words, a picture or the board.
How to use it
Frequently asked questions
Can an AI tutor help with physics problems?
Yes. Say or paste the problem, or open your worksheet in Eddy, and ask for it step by step. You get each move with the math, a hint before the answer, and a graph or a simulation when seeing it helps.
What kinds of simulations can I play with?
Small sandboxes such as a pendulum, a projectile and a circuit: you drag, move sliders and read the numbers. They open on Eddy's desk in the Eddy tab and in Ducky's pill. Ask for one by describing what you want to see move.
Does it explain the idea or only the math?
Both. Ask why and Eddy explains the idea out loud, often with a picture or on the blackboard, before the equations. Then it checks the idea stuck with a your turn question or a quick quiz.
Does it work in a browser?
Not right now: DuckyHelper is a Mac app (macOS 14 or later, Apple silicon), with no Chromebook or web version. In the app, Eddy teaches in its own tab, and Ducky draws on your own worksheet on screen.
