INDEX // 01 REASONING ENGINE
Paste any function, class, or LeetCode solution. AlgoLens steps through the real execution line by line, no console.log needed.
Watch variables, arrays, trees, and heap structures update live as the code runs. Every state change is visualized as it happens.
See the shape of the algorithm, not just the output. Recursion, pointers, and traversal patterns become visible instead of imagined.
Import any LeetCode problem, paste your solution, and witness variables, pointers, and iterations morph into visual state trees in real-time.
AlgoLens runs a secure custom Python interpreter in the backend. As you step through code, it traces local scopes, registers operations, and feeds state mutations directly to the visual canvas.
