Smarana is a spaced repetition platform for mastering algorithm patterns, with a powerful Chrome extension that works directly on coding websites.

It helps developers retain LeetCode, Codeforces, AtCoder, and CodeChef problems using scientifically optimized review schedules instead of relying on random practice.

Smarana ensures you revisit the right problem at the right time so patterns actually stick.
