Easily check for specific tags to see if problems are aligned with your expertise or not. 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.
Codeforces Notes

Simple, but powerful! - The idea: Writing “what you learned” once you’ve solved a problem helps you retain the learnings for a long time. This method of practice is used by countless competitive programmers. - Notes are safe: The notes are attached to your email address, this allows them to be retained across machines and codeforces accounts. - “Export to CSV” will be added ASAP. - “All notes” option on your codeforces profile page

The ‘Unsolved Problems’ shows a count of all problems attempted with not correct verdict and also lists them. The extension communicates only with the Codeforces API and runs entirely on the browser.
