Everything you need to know about getting started

You tell us what you are weak at — Arrays, Trees, DP, Graphs, etc. Our AI analyzes your input and pulls targeted problems from top platforms. Each problem is chosen to close a specific gap in your understanding, not just random practice.

Yes, CrackCode is completely free. All core features including problem curation, AI suggestions, and personalized problem lists are available at no cost.

Random practice wastes time on topics you already know. Our AI focuses only on your weak areas, giving you a curated list that maximizes improvement in the shortest time. Every problem has a purpose.

Yes. Beginners can start with foundational topics and build up. The AI scales with you — as you improve, the problems get harder. You are always solving at the right level.

We curate problems from LeetCode, Codeforces, HackerRank, AtCoder, and other major competitive programming platforms. You get the best problems from each, tailored to your needs.

No. CrackCode works standalone. Just tell us your weak areas and we generate your problem list. No account syncing required.
