LeetCode Review Planner is a Chrome extension for leetcode.com.
It helps you review solved problems with Ebbinghaus-style intervals, notes, time tracking, and a clean dashboard.
Never forget solved problems again.
Learn once, retain long-term with spaced repetition.
The Ebbinghaus forgetting curve says memory drops quickly after learning, then slows down.
The best strategy is short, repeated reviews at increasing intervals.
| Plan | Review Days |
|---|---|
| Full | 1, 3, 7, 14, 30, 60 |
| Light | 3, 10, 30 |
You can also edit interval plans in Settings.
