CF Simplify bởi 3N1GM4

CF Simplify adds a "Simplified statement" card to Codeforces problem pages. It replaces the story with a short, formal description of what you are given and what you must compute or print, and keeps every limit, guarantee and output rule.

It is built to leave out solution hints. The rewrite rules forbid algorithms, observations and complexity remarks, and an automatic check catches hint-like wording before a statement is shown. You can switch between Simplified and Original with one click, and the examples and notes stay as they are.

Fair use in contests. Codeforces does not allow AI summaries of problems during running contests. CF Simplify checks the contest status and stays paused until the contest is finished.

Free for everyone. Simplified statements come from a shared, pre-built library, so no account or API key is needed. If a problem isn't in the library yet, you can optionally add your own free API key (Google Gemini, Groq, OpenRouter or a local Ollama) in the settings to simplify it yourself. Your key stays in your browser.

Privacy. No analytics, no tracking, no ads. The extension only contacts the shared library and the Codeforces API, and your chosen AI provider if you add a key.

Note: statements are rewritten by AI and can contain mistakes. Use "Report a mistake" under a statement, or switch to Original when something looks off.
