DSA Spaced Repetition

Master DSA problems with spaced repetition. Smart review scheduling across popular coding platforms.

HOW IT WORKS • Visit any problem page - the widget appears automatically • Mark it as solved and rate your recall: Forgot, Hard, Good, or Easy • The algorithm schedules your next review at the perfect interval • Problems you struggle with come back sooner; easy ones fade away • Override the schedule anytime - reschedule reviews to a custom day • Drag the widget anywhere on the page to keep it out of your way BUILT-IN QUESTION LISTS • Blind 75, NeetCode 150 & LeetCode 75 for interview prep • Path to Guardian - 698 curated problems across 20 topics for deep DSA mastery • Set different problems/day per list (e.g., 2 from NeetCode + 3 from Path to Guardian) • Queue by topic or randomly - focus on weak areas like DP, Graphs, or Trees • Problems are auto-queued daily into your review • Track progress with visual completion rings and topic-wise breakdowns REVIEW QUEUE • See today's due problems at a glance in the popup • Click any problem to jump straight to it • Track your daily streak and progress ANALYTICS DASHBOARD • GitHub-style heatmap showing your entire year of activity • Daily completion ring - hit 100% when all due problems are done • Solve stats: average per day, best day, current streak • Activity chart, difficulty breakdown & review forecast • Platform breakdown across all supported sites • Daily time tracking - see how long you spend practicing • Topic-wise progress bars per list - see exactly where you're strong and weak • Full problem table with ease factors, intervals & status KEY FEATURES • Works across 6 major coding platforms automatically • Path to Guardian - 698 problems across 20 topics for CP mastery • Curated lists - Blind 75, NeetCode 150 & LeetCode 75 with daily auto-queuing • Per-list queue config - customize problems/day for each list independently • Topic-wise queuing - focus practice on specific algorithms • SM-2 algorithm - the same algorithm used by Anki • Draggable widget - move it anywhere on the page • Reschedule reviews - override the algorithm when needed • Daily notifications - get reminded when problems are due • 100% offline - all data stored locally on your device • Zero accounts, zero sign-ups, zero data collection • Clean dark UI that blends with coding platforms • Lightweight - no impact on page performance PRIVACY This extension stores everything locally. No data is sent to any server. No analytics, no tracking, no accounts. Your data stays on your device. Perfect for anyone preparing for coding interviews, grinding competitive programming, or wanting to retain DSA solutions long-term.
