170+ step-by-step lessons covering every DSA pattern — from Big-O basics to Hard problems — with quizzes and flashcards to lock it in. Built to actually understand, not just memorize.
Most DSA resources are walls of text. AlgoViz is visual, pattern-first, and interview-focused.
Each topic starts with a master map — learn the pattern, then drill problems. Never brute-force memorize again.
Every problem is a 24-slide arc: intuition → trap → insight → solution → interview playbook. Walk through it at your pace.
800+ questions and active-recall flashcards on every topic — check your understanding and prep for interviews, not just read.
Full-text search across every slide. Jump straight to any concept, pattern, or problem in a tap.
Every problem includes what to SAY out loud, common mistakes, and follow-up questions interviewers actually ask.
A curated 6-phase curriculum takes you from zero to Blind 75 coverage. No gaps, no random jumping.
Built dark from the ground up. Code blocks, diagrams, and tables — all readable at 2am before your interview.
17 topics, each with a master overview deck, individual problem deep dives, and quizzes.
All 170+ lessons, every quiz, every flashcard, full-text search. Open /app/ and start reading — no sign-up required.
