Key Features: Precision Tag Filtering: Easily input the tags you want to practice (e.g., dp, math) and strictly exclude the topics you want to avoid (e.g., geometry, constructive algorithms).

Smart Handle Integration: Enter your Codeforces handle to seamlessly integrate your user data. You can instantly filter out and hide problems you have already solved (AC) to save time.

Spoiler-Free Mode: Toggle the "Hide Tags" option to remove the tags column from the search results, preventing unwanted hints before you attempt a problem.

Popularity Sorting: The results are automatically sorted by the number of successful solves, bringing the most well-known and high-quality problems to the top of your list.
