LeetCode Recall: Video Solutions & Spaced Repetition

Watch the best video solution right inside LeetCode, no YouTube rabbit hole, then revise with spaced repetition before you forget.

Stop forgetting the LeetCode problems you've already solved. LeetCode Recall adds two things beside the LeetCode editor: video solutions you watch without leaving the page, and spaced-repetition reviews so solved problems stay solved. 🎯 Watch without the YouTube rabbit hole Looking up a solution on YouTube usually means a feed of recommendations, autoplay and an hour gone. LeetCode Recall plays the explanation in a small player right beside your code, with no feed, no autoplay into the next video and no comments, so you watch, understand and get back to solving. ▶ Video solutions, picked for you - The three most-viewed explanations for each problem, ready in Chrome's side panel. - On a problem list or study plan, every problem on the list gets a video. - A spoiler guard keeps solutions blurred until you choose to look. ⏪ Spaced repetition that actually tests you - After every Accepted submission, answer one question: how did it go? LeetCode Recall schedules the next review with FSRS, the algorithm modern Anki uses. - A 4-week calendar shows what's due today and what's coming. - Review mode resets the editor and hides the videos, so a review is real recall, not re-reading. - Save a one-line insight for each problem and check yourself against it. - A daily reminder, a due count on the toolbar icon, streaks and a readiness score. - Sign in to back up your schedule and use it on any computer.
