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.
