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.

Features

Estimated Problem Rating

Fetches and displays estimated problem ratings from Clist on the problem page.

Helps users gauge problem difficulty before actual ratings are released.

Allows users to compare estimated ratings with actual ratings once they are available.

Hide/Reveal Tags & Ratings

Hide problem tags and ratings to avoid biases while practicing.

Click to reveal or hide individual tags as needed.

Different colors for each state (hidden/revealed) to ensure a smooth UI experience.

Enhances problem-solving by allowing a more self-assessed approach without prior hints.

Works seamlessly with Codeforces UI, integrating naturally into problem pages.

Sort Tags by User Activity
