AI product read

Productivity enhancement tool for CSES Problem Set

Makes solving problems on CSES (Competitive Programming School) easier, faster, and more organized by adding notes, statistics tracking, copy buttons, text-based submission, and sorting/filtering capabilities.

User visits cses.fi → Extension injects UI enhancements → User can add notes, view stats, sort problems, and submit code via text input → Data stored locally in browser

Target users: Competitive programmers using CSES / Students practicing algorithm problems

Source code is heavily minified/bundled (React + ProseMirror + Highlight.js), making some analysis difficult
Could not fully deobfuscate all feature logic due to minification
Assumed CSES requires login based on platform nature and extension features requiring user-specific data

Monetization

No paid features detected

No evidence of paid features in the extension. The extension uses chrome.storage.local for persistence (free), has no payment integration, no subscription gating, and no upgrade/payment UI. The keyword 'upgrade' found in static analysis was from React library error messages ('react.dev/errors'), not related to paid features. The extension appears to be completely free.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension targets CSES (cses.fi), a competitive programming platform that requires user accounts to track progress, submit solutions, and view personalized statistics. The extension's core features (MyStats, Submit by Text, sorting/filtering problems) rely on CSES user sessions. The extension itself does not implement its own login UI but depends on the destination service's authentication.
