AI product read

Enhance Codeforces problem pages with estimated ratings and customizable tag/rating visibility.

Codeforces problem pages can be cluttered with tags and ratings. Users may want to hide them or see estimated ratings from external sources (clist.by) to better plan their practice. This extension provides controls to hide tags/ratings and displays estimated ratings.

User installs extension, opens popup to enter Codeforces handle (optional for some features) and configure settings (hide tags/ratings, sort tags, colors). When viewing a Codeforces problem page, the extension modifies the DOM to hide tags/ratings if enabled, sorts tags if enabled, and adds an estimated rating section fetched from clist.by.

Target users: Codeforces users / Competitive programmers

The extension relies on external sites (clist.by) for estimated ratings, which may have availability or accuracy issues. The 'Sort Tags' feature requires a valid Codeforces handle and fetches user submission history, which might be slow or fail if the API rate limits are hit.

Monetization

No paid features detected

There is no evidence of paid features, subscriptions, or payment processing in the extension code. The extension uses free APIs (Codeforces API, clist.by) and local storage for settings. No premium features or upgrade prompts are present.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login mechanism. It requires the user to manually input a Codeforces handle in the popup settings, but this is not an authentication flow. The extension functions on the Codeforces website, which allows browsing problems without logging in, although some features (like sorting tags by solved problems) require the handle to be set. There is no extension account or destination service login required to use the core features.
