LeetSRS — Spaced Repetition for LeetCode Autor: Matt Drake

Know what to practice. And when to review.

LeetSRS is an extension that helps you remember what you learn on LeetCode through spaced repetition. Solve a problem, rate your recall, and review it when it's due. LeetSRS adjusts your review schedule based on your ratings. Follow a roadmap such as Blind 75 or NeetCode 150 for help choosing what to solve next. Your data stays local by default, with optional GitHub sync across devices. It's free and open source, and no LeetSRS account is required to get started.

How it works

1. Solve a problem on LeetCode. Choose your own or open the next suggested problem from a roadmap.
2. Rate your recall directly on the problem page: Again, Hard, Good, or Easy. Your rating and review history determine when to review it next.
3. Open your review queue for problems that are due. Try each problem again and give it a new rating to update its schedule. Check the calendar to see upcoming reviews.

Roadmaps

Choose Blind 75, NeetCode 150, NeetCode 250, or Grind 75. Track your progress and see your next suggested problem while previously rated problems stay in your review schedule. You can also add problems outside a roadmap.

Your data

Your practice data is stored in your browser by default. Export a backup or import your data from Settings. If you want to sync across devices, connect GitHub and enable sync with a Gist in your own GitHub account. GitHub sync is optional.

Get started

Add LeetSRS to your browser, open a problem on LeetCode, and rate your recall after your first attempt to schedule a review.
