Stop Reading. Start Seeing. Algorithms finally click when you watch the data move. Algora turns 11 core computer-science algorithms into interactive, step-by-step animations you control — and explains the reasoning behind every important step. EVERY ALGORITHM, FIVE WAYS - LEARN — a plain-English breakdown, an everyday analogy, and its speed/memory character. - VISUALIZE — play, pause, step forward and back at 0.5×, 1×, or 2×, with the “why” behind key moves. - PLAYGROUND — feed in your own data (or a preset that exposes a worst case) and run it. - QUIZ — lock in what you learned with next-step and complexity questions. - PATTERN — the core strategy, its strengths, and its constraints on one card. WHAT’S INSIDE - Sorting: Bubble, Selection, Insertion, Merge, Quick - Searching: Linear, Binary - Trees & Graphs: Breadth-First Search, Depth-First Search - Interview Patterns: Two Pointers, Sliding Window BUILT FOR - CS students who want intuition, not just pseudocode - Bootcamp learners filling the fundamentals gap - Anyone prepping for technical interviews who’s tired of re-reading the same explanations WHY IT WORKS Reading about Quick Sort tells you what a pivot is. Watching the pivot get placed — step by step, at your speed, with the reasoning on screen — is how it sticks. Every number in every animation reflects the real algorithm state. Nothing is faked. FREE TO START Bubble Sort, Binary Search, and BFS are free forever, plus a preview of every locked algorithm’s quiz.
