About CF UpsolveX Companion
CF UpsolveX Companion: Your Codeforces Productivity Sidebar
Transform the way you practice on Codeforces. CF UpsolveX Companion seamlessly injects a smart, prioritised upsolve queue directly into the Codeforces website, ensuring you never miss a learning opportunity after a contest.
Stop scrolling through endless problemsets or losing track of which problems you failed. Our intelligent sidebar calculates exactly what you need to solve next to maximize your rating growth—all without ever leaving Codeforces.
🚀 Key Features:
• Smart Priority Queue: Automatically tracks the problems you missed in contests and ranks them using a custom priority algorithm based on recency, difficulty (compared to your rating), and failed attempts.
• Seamless UI Integration: Injects a beautiful, dark-themed, glassmorphic sidebar into Codeforces. Access it instantly via the glowing "CF UpsolveX" button in your navbar.
• Live Statistics: At-a-glance KPI cards show your current pending upsolves, completion rate, total upsolved count, and your daily consistency streak.
• Dual-Mode Operation:
-> Registered Users: Syncs with your full CF UpsolveX account for deep analytics.
-> Unregistered Users: Works instantly as a standalone extension! We pull your data directly from Codeforces and calculate your priority queue locally.
• One-Click Practice: Click on any problem in your priority queue to instantly open it in a new tab and start coding.
⚙️ How it Works: The extension detects your Codeforces handle automatically. It then fetches your contest history and submissions to find problems you attempted but didn't solve, or problems from contests you participated in but didn't attempt. Harder problems (relative to your rating) and problems you've failed multiple times bubble to the top of your queue.
Track. Upsolve. Improve.
Turn your missed problems into your biggest rating gains. Install CF UpsolveX Companion today and make deliberate practice your default habit.
