Three domains, each with step-by-step interactive visualizations

Sorting, searching, trees, stacks, queues — every step visualized with full interactive control.

Regression, clustering, classification — adjust parameters and watch the model adapt in real time.

Search algorithms, game trees, and intelligent agents — see how AI reasons through decision spaces.

01
Choose an algorithm
Pick from 30+ algorithms across DSA, ML, and AI. Generate a random dataset or supply your own. Adjust parameters like array size or cluster count before you begin.
02
Watch every step
Hit play and watch each comparison, swap, or iteration animate in real time. Pause at any moment, step forward or backward, and change the speed to match your pace.
03
Build real intuition
Enable debug mode to see why each decision is made. Experiment with edge cases — nearly-sorted arrays, single clusters, adversarial inputs — until the algorithm's logic becomes second nature.
