Algorena

Don't just watch algorithms. Call their next move. Algorena teaches algorithms the way they actually make sense: by running them. Every lesson is the same four steps. Watch the algorithm run, step by step, with every decision narrated. Then the machine stops mid-execution and asks you to call the next move — which cell does binary search look at now? Which neighbor does the queue serve? You answer, you find out immediately, and a wrong answer tells you exactly which idea slipped. Then three questions prove you understood the concept, not just the animation. Nothing here is a video. Every animation is the real algorithm executing on real data, generated fresh each time you practice — so you can never memorize a run. WHAT YOU LEARN • 58 skills across 18 tracks, from linear search to A* pathfinding • Free forever: arrays and search, two pointers and sliding window, prefix sums, the first sorts, stacks, queues and linked lists — 15 complete lessons, full quality, no teasers • Pro adds the advanced 43: merge and quick sort, heaps, radix, Timsort, hash tables, Bloom filters, LRU caches, BSTs, BFS and DFS, Dijkstra, topological sort, union-find, Kruskal, Prim, Bellman-Ford, Floyd-Warshall, recursion and backtracking, dynamic programming, flood fill, A*, KMP, Rabin-Karp, Boyer-Moore, tries, Huffman coding, minimax, alpha-beta pruning, quadtrees, convex hulls and Monte Carlo HOW IT WORKS • See — the algorithm runs on a live stage, with pseudocode highlighting the exact line executing • Predict — the run pauses at every real decision point and hands you the wheel • Understand — miss one and you get the specific misconception, not a red X • Prove it — three concept questions close every lesson A COACH THAT ACTUALLY WATCHES Algorena remembers which mistakes you repeat — not how many, but which kind. "You've been eliminating the half the target is actually in." Then it offers a three-round drill on exactly that. The Daily 5 mixes five skills a day, weakest first. BUILT FOR THE INTERVIEW, AND FOR AFTER IT Mastery per skill, a rank that climbs with the whole curriculum, and a streak that only asks for five minutes. ALGORENA PRO • All 43 advanced lessons • The Coach's drills and the Daily 5 across all 58 skills • No ads, ever • Every future lesson — included as the curriculum grows • One payment, shared with your family — no subscription PRIVACY, FOR REAL No account. No sign-in. No analytics of our own. No servers. Your progress never leaves your device — we couldn't see it if we wanted to.

The clearest difference is ads: Kodi AI at none against Algorena's shown. Kodi AI also leads on update cadence (every 4 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
