## Description

Carrot is a Chrome extension designed to enhance your Codeforces experience by providing fast and accurate rating predictions. For active contests, Carrot calculates and displays real-time rating changes and the delta required to rank up, adding new insightful columns to the ranklist without clutter. Post-contest, it reveals final deltas and rank changes to help users analyze their performance comprehensively.

All computations happen locally in your browser by communicating solely with the official Codeforces API, ensuring privacy and speed. Users can toggle the visibility of Carrot’s additional columns according to their preferences. Note that while Carrot offers precise predictions, its accuracy is affected by the recent changes in Codeforces rating systems. For users with limited data, alternative tools like CF-Predictor might be more suitable. Bug reports and suggestions are welcomed through the project's GitHub repository.
