LeetCode Revision Buddy

Daily spaced-repetition revision for LeetCode

Revision Buddy helps you retain algorithmic patterns and prepare for coding interviews by applying spaced repetition to your LeetCode practice. Instead of manually tracking what to review, Revision Buddy selects three problems daily focused on topics you have already practiced and prioritises questions that you haven't done before, bringing back challenging topics sooner and spacing out the ones you have mastered. Key Features Spaced Repetition Algorithm: Automatically adjusts review intervals based on how difficult you find specific topics. Curated Problem Sets: Pulls practice problems from popular lists including Blind 75, NeetCode 150, and Striver's A2Z Sheet. Seamless History Sync: Imports your solved history directly from leetcode.com while you are logged in. Post-Solve Rating: Rate each problem after completing it to continuously fine-tune your personal revision schedule. Daily & Weekly Updates: Optional daily notifications and weekly progress summaries via email to help you stay consistent. Frictionless Authentication: Fast, passwordless sign-in using a one-time email code. Adjustable weights: Customise the importance given to certain topics with ease (increasing the weight of a topic, say two pointers, will increase the likelihood of getting a two pointer question) How It Works Sign In: Log in using a one-time passcode sent to your email. Sync: Log into LeetCode to automatically import your problem history. Practice: Receive three targeted problems daily tailored to your revision needs. Rate & Adapt: Rate completed problems to refine future recommendations.
