I've been practicing competitive programming for over two years and wanted more control over my training sessions on Codeforces. So, I built Upsolver Tool, a tool designed to help you customize your problem-solving experience.

What does Upsolver Tool offer? Advanced Problem Filtering: Customize your problem selection based on tags (e.g., dynamic programming), difficulty ranges, and contest types. You can include problems with specific tags, exclude certain topics, or even focus only on problems with exactly the tags you want—giving you full control over your training focus.

No Contest Spoilers: Automatically avoid selecting problems from contests you want to join virtually, ensuring your experience remains spoiler-free.

Group Training Support: If you're practicing with friends, the tool ensures you don’t select problems that anyone in your group has already solved, so everyone can work on new challenges together.
