CF Catalyst is a Chrome extension that enhances problem-solving on Codeforces by providing progressive hints. Designed for users who find themselves stuck on difficult challenges, the extension offers step-by-step insights while preserving the integrity of the original problem. Users can receive hints that are aligned with editorial reasoning, allowing for a deeper understanding without revealing complete solutions. This feature encourages users to engage actively with the problems instead of relying on full answers.

The hint system is coin-based, where each hint costs 10 coins, promoting thoughtful usage. Users earn coins through successful submissions and daily activities, incentivizing continued problem-solving. With its clean and non-intrusive design, CF Catalyst integrates seamlessly into the Codeforces interface, making it a valuable tool for those looking to tackle more complex problems while maintaining a sense of independence in their learning.
