In the DuckyHelper Mac app." updated: "2026-10-09" --- Mac app # 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. [Download for Mac](https://duckyhelper.com/download/)[Meet Eddy](https://duckyhelper.com/eddy/) One question, shown ## 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. Simulations ## 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. [Guide: simulations](https://docs.duckyhelper.com/study/simulations/) In Eddy and in the Mac pill 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. Graphs you can move Ask to graph position or velocity against time and you get a graph you can hover, pan and zoom, with sliders for the letters. Forces and steps ## 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. [Guide: the blackboard](https://docs.duckyhelper.com/eddy/blackboard/) On your own worksheet (Mac app) 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. Hints, then the answer 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. ## Physics study guides ### All physics guides Motion, forces, energy, waves and circuits, each with a worked example. ### Newton's laws of motion Inertia, F = ma and equal and opposite forces, with examples. ### Work and energy Where energy goes when something speeds up, climbs or stops. ### Projectile motion Split the motion into across and up, then solve each. ### Ohm's law and circuits Voltage, current and resistance in series and parallel. ## Ask Eddy Say one of these out loud. Eddy picks how to show it: words, a picture or the board. What is E = mc² saying? Show me how a projectile moves Why is the sky blue?

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. ## More subjects ### Math: worked steps, moving graphs, and hints before the answer An AI math tutor that explains one move at a time: worked steps, graphs you can move, hints before answers. In the Mac app, right over your homework. ### Biology: labelled pictures you can tap, read and quiz yourself on An AI biology tutor that answers with labelled pictures: ask how blood clots or how muscles move, tap any part to ask more, then quiz yourself. On a Mac. ### Chemistry: see the atoms, then work the equations step by step An AI chemistry tutor that shows what atoms are doing: labelled pictures of bonds, steps for every equation, quizzes and flashcards. In the DuckyHelper Mac app. ### History: labelled pictures, maps, timelines and sources you can check An AI history tutor that shows the past: labelled pictures, maps and timelines you can explore, and sources read with you and cited. In the DuckyHelper Mac app. ### Writing: feedback on your own draft, never a ghostwriter An AI writing tutor that reads your own draft with you, asks what you mean and points to what is unclear, and leaves the writing to you. On a Mac. ### Languages: speak out loud, get scored, and keep what you miss An AI language tutor you practice with out loud: hear a word in syllables, say it back, get each word scored, and keep what you miss as flashcards. ### Computer science: run it, step through it, and write it yourself An AI computer science tutor: run your code against tests, step through it line by line to see the variables change, and get hints instead of the solution. ### Music: chords on a labelled keyboard, strings, scales and rhythm An AI music theory tutor that shows the sound: why a minor chord sounds sad on a labelled keyboard, how a string makes a note, rhythm in numbers. On a Mac. ### Art: perspective you can change, and paintings explained part by part An AI art tutor that shows how pictures work: perspective drawn on a picture you can change, paintings explained part by part, art history read with you. ## Keep reading Free high school physics study guides: kinematics, projectile motion, Newton's laws, free body diagrams, energy, momentum, circuits and waves. ### Try Eddy: four things to say out loud in your first minute Try Eddy in the DuckyHelper Mac app: open the Eddy tab, press Talk to Eddy and ask one of these questions out loud. ### Eddy: the voice tutor in the DuckyHelper Mac app's Eddy tab Eddy is the voice tutor in the DuckyHelper Mac app: talk out loud and it teaches on a blackboard, with labelled pictures, quizzes and your own homework file. ### Small sandboxes you run yourself: drag the ball, move a slider, read the numbers Ask DuckyHelper to show you how a pendulum, a projectile or a circuit works and get a small sandbox to run yourself: drag, change a slider, read the numbers. ### A picture made for your question, labelled as Eddy explains; tap any part to ask about it Ask Eddy to show you and a picture made for your question comes into focus, labelled as Eddy explains. Tap any part to ask about it, or change it. ### Every subject: one question per subject, shown on screen DuckyHelper is an AI tutor for any subject: math, the sciences, history, writing, languages, code, music and art, each explained out loud and shown on screen.
