Draw physics and circuit diagrams with AI, using textbook symbols
Describe the problem and the tool builds an inclined plane with a block and its forces, a pulley system, a pendulum, a ray diagram through a lens, or a circuit with ammeter and voltmeter. Forces are vectors anchored at the correct point of application; components use standard symbols.
- Mechanics: inclined planes, blocks, applied force, weight, normal force, friction, pulleys, springs, pendulums
- Optics: light rays, plane mirrors, converging and diverging lenses, images of objects
- Circuits: sources, resistors, bulbs, switches, capacitors, ammeters, voltmeters, series and parallel

What you can draw for physics
Every object is a block with physical meaning and anchor points for attaching forces, hanging strings or connecting wires, so the diagram stays connected as you drag.
Pulleys, strings, springs
Fixed and movable pulleys, strings holding blocks, two masses connected over a pulley. Horizontal or vertical springs with adjustable coil count, simple pendulums displaced from the vertical.
Geometric optics
Rays with arrows showing direction, plane mirrors with incident and reflected rays, converging and diverging lenses with focal points and principal axis, objects and images constructed with principal rays.
Series and parallel circuits
Sources, resistors, bulbs, open or closed switches, capacitors, diodes, motors. Ammeters and voltmeters connected in the right place. Wires run at right angles; junctions are dotted.
Labels and values
Write R1 = 10 Ω, U = 12 V, m = 2 kg, angle α = 30° directly on the diagram. Dimension lines with arrows at both ends for lengths and heights.
Standard symbols, print-ready
Electrical components follow the conventional textbook symbols, thin black lines, no garish colors — still clear when printed in black and white.

How to draw physics diagrams in AI mode
Physics has two tabs: Physics for mechanics and optics, Circuits for electrical diagrams. They work the same way.
Choose the Physics or Circuits tab
The Physics tab has inclined planes, blocks, forces, pulleys, springs, pendulums, mirrors and lenses. The Circuits tab has sources, resistors, bulbs, switches, meters and wires.
TipFor a problem with both parts, such as a motor pulling a block, draw two figures and combine them in Word.Describe the problem in physical order
State the object, the surface, then the forces. For example: A 2 kg block on a 30° incline, draw the weight, normal force and friction. For circuits, state the connections: two resistors in series, an ammeter measuring the total current, a voltmeter across R1.
TipSay which forces to draw — the tool will not add forces you did not mention, to stay faithful to the problem.Click Draw and compare with the problem
Check the points of application, arrow directions and meter positions. The AI sees line lists the number of objects, forces and components for a quick comparison.
TipArrow lengths follow relative magnitudes; drag an arrowhead to change the magnitude.Edit with short commands or suggestion chips
Type Change the incline to 45 degrees, Add a pulling force F up the slope, Change R1 to 20 Ω, Add an ammeter to the main branch, Close the switch. Chips are generated from the current diagram — click one to fill it in.
TipChanging a value only changes the label and proportions; the layout stays the same.Drag and adjust by hand
Drag a block and its forces follow. Drag an arrowhead to change direction and magnitude. Select a component to get scale and rotate handles. The library in Advanced mode lets you drop more resistors, bulbs or pulleys exactly where you want.
TipClick a vector to make it dashed for component forces, or turn a segment into an arrow.Copy into Word or export a file
Copy figure to paste into an exam, export transparent PNG for slides, or SVG for Word and PowerPoint. Name the figure and pick a background in the Export panel.
TipCircuit diagrams printed in black and white look best as SVG so component lines stay thin.
Sample prompts for physics
Copy a prompt below, paste it into the description box and change the values to match your problem.
A 2 kg block rests on a 30° inclined plane. Draw the weight P, the normal force N and friction, and label the angle.
Forces are applied at the block's center; angle α is labeled at the foot of the slope.
Two masses m1 and m2 are connected by a string over a fixed pulley; m1 lies on a table and m2 hangs vertically.
The string follows the pulley groove; drag the pulley and the string and both masses follow.
A simple pendulum of length 1 m hangs from point O, displaced 30° from the vertical. Draw the weight and the tension.
Includes a dashed vertical line and the displacement angle arc.
Object AB stands perpendicular to the principal axis in front of a converging lens, beyond the focal length. Construct the image A'B' with two principal rays.
Ray through the optical center and ray parallel to the axis; the image is real and inverted.
A circuit with a 12 V source, resistors R1 = 10 Ω and R2 = 20 Ω in series, an ammeter measuring the current and a voltmeter across R2.
The ammeter sits on the main branch; the voltmeter is in parallel with R2.
Two bulbs L1 and L2 in parallel across a source, switch K controlling the whole circuit, show the direction of current.
Junctions are dotted; the switch is drawn open.
Uses in teaching and learning physics
A few situations where teachers and students use the tool every day.
Mechanics problems with figures
Problems about inclined planes, pulleys and springs almost always need a figure. Type the problem, get the right angle and the right forces, paste into Word.
ExampleA set of 10 incline problems with different angles — change one number and a new figure appears.
Circuit diagrams for tests
Series, parallel and mixed circuits with meters in the right place and standard symbols — no more drawing with Word shapes.
ExampleA question asking for the ammeter reading: the diagram is ready in a minute.
Force analysis on the board
Project the diagram and drag an arrowhead so the whole class sees a force change as the angle increases, or make component forces dashed.
ExampleRaise the angle from 30° to 60° and the component Px grows in front of the students.
Step-by-step optics constructions
Draw the object in front of the lens, add each principal ray with an edit command and capture each step for a guided slide deck.
ExampleSlide 1 object and lens, slide 2 the ray through the center, slide 3 the parallel ray and the image.
Students draw their own diagrams
Students describe the problem in words and compare the figure with their own thinking, practicing force analysis and circuit reading.
ExampleA group draws a parallel circuit and adds the ammeter to the correct branch.
Editing and exporting
Drag and the figure follows, relationships stay true
Drag vertex B and the altitude AH stays perpendicular to BC, midpoint M stays in the middle, a right triangle stays right. The tool stores constructions, not strokes, so you can edit freely without breaking the mathematics.
Toolbar right where you click
Click a segment to make it dashed, add an arrow or show its length. Click a triangle to make it free, right, isosceles or equilateral and to show angle measures and side lengths. No property panel to open.
Scale and rotate like Figma
Select an object to get handles: drag a corner to scale uniformly, drag an edge to change width or height, drag the round handle to rotate. Drag a whole group and every dependent point follows.
Paste into Word at the right size
Copy figure puts an image on the clipboard for Word, PowerPoint or Google Docs. Export SVG for crisp printing — one grid cell equals 1 cm, so printed measurements are exact. Transparent PNG for slides.
A share link carries the whole figure
The share button creates a link that contains the full drawing. Send it to a colleague; it opens ready to edit, no account needed.
Frequently asked questions
Do the electrical symbols follow textbook conventions?
Sources, resistors, bulbs, switches, ammeters, voltmeters and capacitors use the conventional symbols found in secondary-school physics textbooks: resistors as rectangles, bulbs as circles with a cross, meters as circles marked A or V.
Are forces drawn with the correct magnitude?
Force arrows are scaled to the magnitudes you state and stay consistent within one figure. Drag an arrowhead to adjust, or type an exact value in the properties panel.
Can it draw mixed circuits with several branches?
Yes. Describe each branch, for example R1 in series with R2 parallel to R3. If the layout is not tidy, drag components and wires in Advanced mode — wires keep their right angles.
Can it plot motion graphs or i-t graphs?
Graphs use the Function Graph tab of the math tool: same axes and drawing, with the axes renamed t and v or i. See the math diagram page for how to describe them.
What if AI misses a force or draws it the wrong way?
Type an edit such as Add friction opposite to the motion or Reverse force F. The tool keeps what is already correct and only adds or changes the force you mention. Dragging an arrowhead also changes direction and magnitude.
How much is free?
Manual drawing, editing, copying and exporting are unlimited and need no account. The AI part has a daily limit for anonymous users.
