Overview
Train your pattern recognition! Quiz yourself on algorithmic patterns before seeing LeetCode hints, tags, and solutions.
PatternPulse - Free LeetCode Pattern Trainer Stop memorizing solutions. Start recognizing patterns. PatternPulse is a free Chrome extension that trains you to identify algorithmic patterns BEFORE you see LeetCode's hints, tags, and solutions — just like in a real coding interview where you won't have those crutches. HOW IT WORKS When you visit a LeetCode problem, PatternPulse blurs the spoilers (tags, hints, similar questions) and asks you: "What pattern would you use?" Pick from 18 core patterns, and if you're right, the content unlocks. If you're stuck, use progressive hints without giving up entirely. FEATURES • 256 Curated Problems — Hand-picked from NeetCode 150 and LeetCode 75 with accurate pattern mappings and hints • Smart Shields — Blurs tags, editorial, solutions, and similar questions until you identify the pattern • Progressive Hints — Get help without completely giving up • Progress Tracking — See your completed problems and pattern mastery • Streak Counter — Track consecutive first-try solves (no hints, no wrong guesses) • Random Problem — Jump to any unsolved problem with one click • 18 Core Patterns — Hash Map, Two Pointers, Sliding Window, Binary Search, Dynamic Programming, Greedy, Backtracking, DFS, BFS, Stack, Linked List, Heap, Trie, Union Find, Topological Sort, Math, Bit Manipulation, Graph WHO IS THIS FOR? • Software engineers preparing for coding interviews • CS students learning data structures and algorithms • Anyone who wants to stop relying on LeetCode tags as a crutch • Developers who want to build real pattern recognition skills 100% FREE & PRIVATE • Completely free, no premium tiers • No account required • All data stored locally in your browser • No tracking, no analytics, no data collection • Open source This extension is in beta — your feedback shapes it!
