Algomind uses spaced repetition — the same technique used by memory champions — to make sure algorithms and data structures stick in your long-term memory, not just for the next interview.
In 1885, Hermann Ebbinghaus discovered the Forgetting Curve: without reinforcement, we forget ~50% of new information within an hour, and ~70% within 24 hours.
You can grind 200 LeetCode problems and still blank on a binary search during an interview — not because you're bad at algorithms, but because your brain naturally discards information it doesn't see repeatedly.
Memory retention over time (without review)
Memory retention with spaced repetition
Intervals grow exponentially — reviews become less frequent over time
Spaced repetition schedules reviews at increasing intervals — right before your memory fades. Each review resets the forgetting curve at a higher baseline.
The SM-2 algorithm (used by Anki, Duolingo, and medical schools worldwide) adapts to how well you know each concept. Easy problems get pushed further out. Hard ones come back sooner.
We handle the scheduling. You just focus on understanding.
Paste a LeetCode URL and we automatically pull the problem title, difficulty, and description. No manual entry.
Browse curated notes on every major algorithm and data structure — BFS, DP, segment trees, and more — all in one place.
Each morning, your queue shows exactly which problems are due for review based on the SM-2 spaced repetition algorithm.
See your review streak, problems mastered, and upcoming reviews at a glance. Know exactly where you stand.
Rate each review as Again, Hard, Good, or Easy. The algorithm adjusts your next review interval accordingly.
Spaced repetition is efficient by design. Most users spend under 5 minutes per day maintaining their entire problem set.
