Stop forgetting the ones you don't. Leetcode Anki turns LeetCode into a spaced-repetition deck, the same way Anki works for flashcards — except the cards are problems, and a "review" means solving one again from scratch. How it works
  1. Visit the LeetCode problems page. One recommended problem is pinned above the list: your most overdue review, or the next new problem from your queue.
  2. Solve it. When the Accepted verdict appears, rate the recall — Again, Hard, Good, or Easy.
  3. The scheduler (SM-2, Anki's algorithm) pushes the next review out on an expanding schedule: a day, six days, two weeks, a month. Problems you find easy fade into the future; problems that hurt come back soon.
Features • One problem a day, where you already are. No separate app or dashboard — the recommendation lives at the top of the problems page. • Build your deck in one click. Add NeetCode 150 or Blind 75 whole, hit "+" on any problem row, or add from the problem page itself. • A real new-card queue. Lists join the deck unscheduled and are introduced one per day. Skip a week and nothing rots — your real reviews come first, then the queue resumes. • Honest reviews. Opening a due problem resets the editor to the default template, so you recall the solution instead of rereading it. • Multiple decks. Separate decks for NeetCode, interview prep, or weak topics — each problem schedules independently per deck. • Private by design. Your deck lives in your browser's local storage. No account, no server, no tracking. The extension only runs on leetcode.com. Solving a problem once means you knew it that day. Spaced repetition is how you'll know it in the interview. ## Rankings - #106,798 — Overall - #36 — leetcode ## Permissions and access ### Permissions - `storage` ### Content script matches - `leetcode.com` ## Safety - **Risk impact:** Low risk impact - **Risk likelihood:** High risk likelihood ### Analysis details - Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk. - This extension has low user count.
