LeetReminder

Spaced repetition for LeetCode and NeetCode. Saves a problem and reminds you to redo it at 1, 3, 7, 14, 30 and 60 days.

I kept forgetting problems about three weeks after solving them, which is roughly when they tend to come up in an interview. Anki works fine but making cards for code problems is tedious, so I made this instead. Click the button on a LeetCode or NeetCode problem page and it schedules six reviews: 1, 3, 7, 14, 30 and 60 days out. The toolbar badge tells you how many are waiting, and you get one desktop reminder a day if anything is due. There's no easy/hard grading and no way to send a problem backwards. Three things it's deliberately strict about: You can't review early. The checkbox stays locked until the day arrives, because re-solving something the day after you solved it teaches you nothing. You can't miss one either. Nothing expires and nothing quietly advances. A review that came due three weeks ago is still sitting there marked 21 days overdue. Late reviews push the rest back. Do a day-7 review on day 8 and the next one lands on day 15, not day 14, so you always get the full interval from the day you actually did the work. Adding the same problem from LeetCode and from NeetCode gives you one entry with both links. Everything is stored locally on your machine. No account, no server, nothing collected.
