LeetRecall

Hands-free spaced repetition for LeetCode problems.

LeetRecall helps you actually remember the LeetCode problems you solve - not just solve them once and forget. Most people treat LeetCode like a checklist. They solve a problem, move on, and blank out on the same problem two weeks later in an interview. LeetRecall fixes that. HOW IT WORKS LeetRecall runs silently in the background while you use LeetCode normally. Every time you submit a solution, it automatically tracks: - Whether you got Accepted or Wrong Answer - How long you spent on the problem - How many attempts you needed - Whether you peeked at the Solutions or Editorial tab Using the SM-2 spaced repetition algorithm (the same technique behind Anki and other top memory apps), it calculates exactly when you should review each problem again, so you see it just before you'd forget it. PROFICIENCY TRACKING Every problem gets a proficiency level that updates automatically: Novice → Learning → Familiar → Proficient → Mastered The goal is simple: push every problem to Mastered before your interview. FEATURES - Zero setup needed, just install and use LeetCode normally - Automatic submission tracking, no manual input needed - Smart review scheduling using SM-2 spaced repetition - Due Today popup: see exactly what to review each day - Full dashboard with proficiency badges, acceptance rates, and average solve times - Daily 9am reminder notification when problems are due - Badge counter on the extension icon showing due count - Works entirely offline, no account, no server, no data sent anywhere PRIVACY Everything stays on your device. LeetRecall uses Chrome's local storage only. No accounts, no tracking, no data collection of any kind. Perfect for anyone preparing for technical interviews at top tech companies.
