How every problem is made
Real questions, not AI filler.
Sourced from real interviews
Every problem traces to a candidate-reported question — interview debriefs, people we've coached, and each firm's real process.
AI cleans, never invents
AI only tidies the wording, standardizes notation, and lays out the solution steps — it never makes up the problem.
Authored & verified by us
Each solution is written by hand and independently checked for correctness before it ships.
Questions
Can I cancel anytime?
▶
Yes. Cancel anytime from your account settings. You'll keep Pro access until the end of your billing period.
What payment methods do you accept?
▶
We accept all major credit and debit cards through Stripe. Your payment information is handled securely by Stripe and never stored on our servers.
Which problems are free?
▶
400 problems are free across all difficulty levels and topic areas. Free problems are selected to give you a representative sample of easy, medium, and hard questions across the full problem set.
Do I need an account?
▶
A free account (Google or GitHub sign-in) is needed to track progress and unlock Pro. Sign-in takes seconds.
Are the problems AI-generated?
▶
No. The ~400 free problems are built exactly the same way as the Pro ones — the only difference is how many you get. The best way to judge is to work through the free set and decide for yourself before paying anything.
