10 visualizers

Every concept,
rendered live.

Paste real C# or Java code. Get interactive diagrams back. Built on Roslyn AST, .NET 8, and a Rust/WASM microkernel.

▶
FLOWCHART
Paste any C# or Java method and instantly generate a control-flow diagram — decision diamonds, loop back-edges, and function call nodes.
☷
DATA STRUCTURES
Step through code and watch arrays, linked lists, stacks, queues, and binary trees update on a live heap + stack canvas.
◇
OOP CONCEPTS
Watch the heap, call stack, and virtual dispatch table update live as your class hierarchy executes. Supports inheritance, polymorphism, and encapsulation.
↻
RECURSION
Trace recursive calls step by step. Watch the call tree grow, inspect each frame's arguments and return values, play/pause/step at any speed.
▼
ALGORITHMS
Watch sorting and searching algorithms animate step by step. Compare two algorithms side-by-side with live operation counters.

COMPLEXITY
Paste any code and instantly get its Big O notation, a growth curve graph, and a plain-English explanation of why — powered by GPT-4o-mini.
⚙
DFOS — OS CONCEPTS
Explore a live microkernel in your browser. Watch PCB state transitions, CPU scheduling Gantt charts, and physical memory frames — powered by Rust + WebAssembly.
∿
AUTOMATA
Build DFAs, NFAs, PDAs, and Turing Machines interactively. Run input strings step-by-step and watch state transitions animate.
∑
NUMERICAL METHODS
Root-finding, integration, interpolation, ODEs, and linear algebra — visualized with convergence graphs, iteration tables, and interactive zoom/pan.
⊕
BOOLEAN ALGEBRA
Enter any boolean expression and explore it as a truth table, logic gate circuit, step-by-step simplification, and an interactive 3D Karnaugh map.

CS ASSISTANT

Your built-in AI tutor

Ask anything about your code. Powered by Ollama running locally — no internet, no API key required.

youHow does binary search work?
csBinary search divides a sorted array in half each step, eliminating half the search space every iteration — achieving O(log n) time.
