Never touched AI before? Seven interactive labs that teach the core ideas by letting you break things and watch what happens.

AI for Beginners

The Automated Mailroom

See exactly how a computer turns your sentences into numbers to sort the mail.

AI for Beginners

The Galactic Talent Audition

An AI judge picks singers fairly — until you see exactly where its hidden bias comes from.

AI for Beginners

The Maze Runner Puppy

A robot puppy learns to solve a maze from nothing but points and punishment.

AI for Beginners

The Alien Fruit Island

Drop an AI into a pile of nameless alien fruit and watch it find its own groups.

AI for Beginners

The Smart Flashcard School

Train a robot student with picture-and-answer flashcards, then test what it actually learned.

// Learn By Simulating

Simulation Labs →

Interactive ML and DSA simulations — learn by breaking things, not reading slides.

ML Lab

Vectors & Broadcasting Lab

ML Lab

Statistics Arcade

A game-like sandbox for core statistics: mean, variance, and distributions.

ML Lab

Probability Playground

Build intuition for probability distributions through interactive experiments.

ML Lab

Noise & Overfitting Lab

Add noise to data and watch how models react — and where they break.

Robotics Lab

Coordinate Frames

Coordinate frames are reference systems fixed to each joint and link to calculate the precise position and orientation of the robotic arm.

Interactive Simulation 🤖 Robotics

Robotics Lab

Roll Pitch Yaw

Roll, pitch, and yaw represent the three rotational movements that determine the orientation of a robotic arm's wrist in 3D space.

Interactive Simulation 🤖 Robotics

Robotics Lab

Robotic Arm Parts

A robotic arm uses a controller to command actuators that move joints and links to position the end-effector.

Interactive Simulation 🤖 Robotics

Robotics Lab

Jacobians Lab

The Jacobian matrix maps joint velocities to end-effector velocities.

Interactive Simulation 🤖 Robotics

Robotics Lab

Inverse Kinematics Lab

Find joint angles for desired end-effector position.

Graphs & Maths in ML →

Calculus, linear algebra, probability, and optimization — made visual.

$Jaccard Similarity$ Math Lab

Jaccard Similarity

Compare sets visually and see how Jaccard similarity measures overlap.

$The Chain Rule Gearbox$ Math Lab

The Chain Rule Gearbox

A gearbox metaphor for the chain rule — turn one gear, watch the rest follow.

$ROC & AUC$ Math Lab

ROC & AUC

Slide a classification threshold and watch the ROC curve and AUC respond live.

$The Jacobian Matrix$ Math Lab

The Jacobian Matrix

Explore the Jacobian and how it maps small input changes to output changes.

$Support Vector Machines$ Math Lab

Support Vector Machines

Watch an SVM find its separating hyperplane, margin, and kernel trick live.

29 real computer vision algorithms, running live in your browser — from raw pixels to object tracking.

CV Lab

Object Tracking

Lock onto a moving target and keep tracking it even through a total occlusion.

CV Lab

Image Pyramids

Shrink an image level by level, then rebuild it pixel-perfect from the tiny top.

CV Lab

Template Matching (SSD/SAD/NCC)

Watch three matching formulas fight the same lighting change — only one survives.

CV Lab

Watershed Segmentation

Flood a 3D terrain built from image gradients until dams form between touching objects.

CV Lab

Panorama Stitching

Match two overlapping photos, warp one into the other, and watch the seam disappear.
