Algonote

AlgoNote helps you truly understand algorithms by seeing them in motion. Instead of memorizing pseudocode, watch each algorithm run step by step with clear, interactive visualizations.

Whether you are preparing for coding tests and technical interviews, studying computer science, or refreshing the fundamentals as a working engineer, AlgoNote turns abstract concepts into intuitive visuals you can follow at your own pace.

WHAT YOU CAN DO

• Watch algorithms execute step by step with smooth animations
• Follow the running code in sync with each visualization
• Compare how different algorithms solve the same problem, side by side
• Read concise concept explanations that build real intuition
• Replay any step as many times as you need, at your own pace

TOPICS COVERED

• Sorting: bubble, selection, insertion, merge, quick, and more
• Searching: linear and binary search
• Graphs: BFS, DFS, and shortest paths
• Trees and traversals
• Dynamic programming
• More topics added over time

WHO IT IS FOR

• Job seekers preparing for coding tests and technical interviews
• Students learning data structures and algorithms
• Developers who want to refresh the fundamentals

AlgoNote is free to use. Optional rewarded ads let you earn points to unlock additional learning content.

Start seeing algorithms, not just reading about them.
