About LeetClock

Track your LeetCode solve times automatically — with zero manual toggles, stopwatch clicking, or context switching. LeetClock runs seamlessly in the background while you code. It measures your active problem-solving duration, logs your history, syncs metadata into your LeetCode Notes, and delivers instant submission feedback when you get that Accepted verdict. -------------------------------------------------- ⚡ KEY FEATURES -------------------------------------------------- • ⏱️ Live Toolbar Timer Monitor active solve time directly on your browser toolbar (MM:SS format) with a high-contrast Cyber-HUD badge. • 📝 Automated LeetCode Notes Sync When your submission receives an Accepted verdict, LeetClock automatically appends a clean session log (Start Time, End Time, Active Duration) directly into LeetCode's native text editor. • 🎮 Pop-Culture Submission Feedback Receive high-dopamine, dynamic Cyber-HUD popups on Accepted submissions and relatable coping memes for TLE, Wrong Answer, and runtime errors. • 📊 Recent Solve History Keep track of your latest solved problems, solution times, and timestamps directly from the extension popup dashboard. • 🧠 Intelligent Navigation Detection Automatically resets and initializes timing when jumping between different LeetCode problems or daily challenges without requiring page reloads. • 🔒 100% Private & Local No sign-ups, no external servers, and no data tracking. Everything is stored locally using chrome.storage.local. -------------------------------------------------- 📖 HOW TO USE -------------------------------------------------- 1. Open any LeetCode problem — the timer starts automatically. 2. Solve the problem as usual. 3. Submit your code. 4. On Accepted, your timing details are automatically saved and appended to your LeetCode notes! -------------------------------------------------- Built for competitive programmers and interview candidates who care about speed, consistency, and focus.
