About Cermonix — DSA AI Coach & GitHub Sync

Master Data Structures & Algorithms without ever switching tabs or spoiling solutions! Cermonix is your personal AI coach and solution vault built directly into the world's most popular competitive programming and coding platforms: LeetCode, GeeksforGeeks, Codeforces, and AtCoder. Rather than giving away complete answers, Cermonix acts like an empathetic senior technical interviewer. It provides tiered Socratic hints, analyzes tricky edge cases, and guides you toward optimal time and space complexity. When you solve a problem, sync your code directly to your GitHub repository with a single click! ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✨ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🤖 Socratic AI Coach • Tiered Guidance: Request subtle directional nudges, edge-case checks, algorithmic hints, or complexity breakdowns without spoiling the solution. • Context-Aware: Automatically ingests the problem statement, constraints, your current editor code, language, and recent submission errors. • Dual Reasoning Modes: Fast standard reasoning for quick pointers, or deep high reasoning for rigorous algorithmic proofs and edge-case exploration. • Inline Key Setup: Connect your own Google Gemini API key directly inside the side panel or settings. 🐙 1-Click GitHub Synchronization • Direct Commit Flow: Push solutions with clean formatting, auto-generated commit messages, and customizable directory structures (e.g., `leetcode/`, `gfg/`, `codeforces/`, `atcoder/`). • Interactive Repo & Folder Browser: Search repositories, explore subfolders with an intuitive breadcrumb finder, or create new repositories directly from the extension. • Conflict-Safe: Check existing files before pushing to avoid overwriting your work. 🌐 Multi-Platform Support • LeetCode: Works seamlessly across standard problem pages. • GeeksforGeeks: Full problem parsing and editorial sync. • Codeforces: Problem set, contest, and gym integration with rating-aware metadata. • AtCoder: Contest problem support with exact task score handling. • Contest Anti-Cheat Protection: The extension automatically suppresses interactive hints during live active contests to preserve contest integrity and fair play. 🔒 100% Client-Side Privacy & Security • Zero Intermediate Servers: Prompts and commits travel directly from your browser to Google Gemini (`generativelanguage.googleapis.com`) and GitHub (`api.github.com`) via HTTPS. • AES-GCM 256-Bit Encryption: Sensitive tokens and credentials are encrypted using the browser Web Crypto API and saved in `chrome.storage`. • Zero Telemetry: No analytics, tracking scripts, or data brokers. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 HOW TO GET STARTED ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Install Cermonix from the Chrome Web Store. 2. Open any problem on LeetCode, GFG, Codeforces, or AtCoder. 3. Click the floating Cermonix icon in the bottom right corner (or press the extension toolbar icon). 4. Enter your free Google Gemini API key in the AI panel, or connect your GitHub Personal Access Token in the GitHub tab. 5. Practice, learn, and sync your DSA journey! ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛡️ PERMISSIONS & TRANSPARENCY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Cermonix requires only the permissions strictly necessary to interact with problem editors and push code: • Storage: Securely persists encrypted API keys, tokens, and preferences locally. • ActiveTab: Injects the side panel only when activated on supported coding platforms. • Host Permissions: Connects directly to coding platforms for context extraction, Google Gemini for AI hints, and GitHub for repository sync.
