Three Ways to Master DSA
Practice. Visualize. Interview.
Most platforms give you a blank editor and good luck. AlgoInsight gives you a visualizer to understand, an AI to grade you, and a mock interviewer to pressure-test you - all three, every problem.
AI-Powered Code Practice
Write real solutions in a Monaco IDE across Python, JavaScript, Java, C++, TypeScript, and Go. Our AI evaluates correctness, time & space complexity, edge cases, and code quality - giving feedback like a senior engineer at your side.

From Zero to Offer-Ready
A structured loop that compounds: understand → code → interview → review. Repeat it for every topic.
Pick a Topic
Browse 500+ problems across 18 topics - Arrays, Trees, DP, Graphs and more. Filter by difficulty or company tag.
Visualize First
Before writing a line of code, watch the algorithm execute step-by-step. Build real intuition, not just memorized patterns.
Code It
Solve in the Monaco editor in your language of choice. AI checks correctness, complexity, and edge cases instantly.
Simulate the Interview
Run a timed mock session with an AI interviewer who asks follow-ups, gives hints, and scores your solution like a real screener.
Review & Improve
Get model answers, a score breakdown, and weak-area insights after every session. Every rep makes the next one sharper.
