30-second insight recall instead of 30-minute re-solves. Pattern-level retention tracking. A scheduler that adapts to your forgetting curve.
Can you state the core insight?
Not SM-2. Not Anki defaults. A state-of-the-art algorithm that models your personal forgetting curve. Stability, difficulty, and elapsed time per card.
Your intervals are not guesses. They are computed.30-second pattern recall instead of 30-minute re-solves. Each card isolates the core invariant. The one line of reasoning that unlocks the problem.
Recall the pattern, not the syntax.Retention tracked per pattern: sliding window, monotonic stack, dp on trees. Not per problem. When a pattern decays, you get a different problem in it.
Weak on graphs? You will know before the interview.Daily time cap with auto-deferral. Reviews do not pile up into an unmanageable backlog. A 7-day forecast shows what is coming.
25 minutes a day. No more, no less.Per-company readiness percentage. Coverage, retention, and recency combined into one score. Know exactly how prepared you are for Meta, Google, or wherever you are targeting.
A number, not a feeling.Blank, Hint needed, Solo slow, Solo fast, Trivial. Each button shows your projected next interval before you click it.
See the future before you rate.Anki reviews cards. leetprep reviews patterns. Each insight card isolates the invariant, the mental model that transfers across problems. The FSRS-5 scheduler is a generation ahead of SM-2.
No. You solve on LeetCode. leetprep handles the retention layer. It is a recall engine, not a code editor. Post-launch, a browser extension will auto-sync your submissions.
Free gives you 10 reviews per day and 3 tracked patterns. Enough to see if FSRS-based recall works for you. Pro removes all limits and adds the readiness dashboard, workload forecast, and full pattern coverage.
Yes. Monthly subscriptions cancel instantly. Annual subscriptions are refundable within 14 days. Lifetime is forever.
Curated, not scraped. Sliding window, two pointers, monotonic stack, topological sort, union-find, dp on trees, backtracking with pruning, binary search on answer, and 20+ more. Each tagged to specific problems, not broad LeetCode categories.
All data is user-scoped with row-level security. We do not sell data, run ads, or share your problem history. You can export everything anytime on Pro.
The interview is pattern recognition under pressure. Train the recall, not the typing.
