Practicing on Codeforces is crucial for improving competitive programming skills, but it lacks some flexibility. Problems don't get official ratings immediately after a contest, making difficulty assessment harder. Additionally, problem tags may give unintended hints, affecting unbiased problem-solving.

To address this, I present CF Problem Insights, a Chrome extension designed to refine your problem-solving experience. It offers estimated problem ratings before official ratings are released and lets you hide/show problem tags individually, ensuring unbiased practice. It also helps track your progress by sorting tags based on your past submissions to highlight weaker areas.
