Practice LeetCode problems with spaced repetition: track each attempt on the problem page and review when it's due.

Remember the reasoning behind every LeetCode problem you solve. You solve a problem, move on, and three weeks later you can't remember why your greedy approach failed or which edge case broke your first submission. Re-solving at random wastes time on problems you still remember and misses the ones you're about to forget. ankileet schedules the whole problem and brings it back right before you'd forget it, so you review it the way you learned it: by solving it again on LeetCode. HOW IT WORKS 1. Practice: open a problem on leetcode.com and click Start practice in the ankileet panel. Every submission is recorded with its verdict and failing test case. 2. Rate: when a review is due, solve the problem again, finish the session, and rate how it went. FSRS-6, a modern spaced-repetition algorithm, schedules the next review. A first practice comes back a day later. 3. Learn: record why an attempt failed, or let session analysis suggest a cause, and see which skills keep slipping across problems. FEATURES • Practice sessions on the problem page: ankileet tracks when you start, every submission and its verdict, and how long you actively worked. An Accepted verdict doesn't end the session; you decide when you're done. • Reviews on schedule: the toolbar popup shows what's due today and opens the problem with its review session ready to start. • A mistake profile: confirmed causes of failure (approach, invariant, edge cases, complexity, implementation, concept) are counted once per session, so retrying a problem five times doesn't inflate a weakness. • New problems worth trying: each day ankileet suggests a problem you haven't attempted, chosen from the similar questions of problems you practiced, and says why it picked it. • Optional AI session analysis with your own key: after a session, ankileet can explain what went wrong from your attempts, code changes, and judge output, using your own Anthropic, OpenAI, DeepSeek, or Google Gemini API key. Suggested mistakes count only after you confirm them. • Nothing lost offline: practice work is saved in the extension first and syncs as soon as ankileet is reachable. • A web dashboard at ankileet.com: today's reviews, the problems you're most likely to forget, your review history, and a page for every problem with its sessions, notes, and submissions. • English or 简体中文 interface.
