About Codeforces tags checker
This Chrome extension helps Codeforces users focus on the challenges that match their skills by filtering problems based on key tags, without revealing all the tags upfront. By minimizing unwanted hints, it preserves the problem-solving experience and ensures a more targeted approach to practice. You can also discover new challenges with the random problem generator — filter by rating range and specific tags to get a problem tailored to your level and interests.
