Cermonix — DSA AI Coach

About

Cermonix is your personal AI coach for Data Structures and Algorithms, built directly into LeetCode. Instead of getting stuck and immediately looking at the solution, Cermonix acts like a real technical interviewer to guide you towards the optimal approach without giving away the answer upfront.

What it does: Cermonix adds a seamless, non-intrusive AI chat interface directly to your LeetCode problem pages. It automatically reads the problem description, your current code, and any compilation or logic errors you encounter when you submit. You can ask for progressive hints, algorithmic explanations, or help debugging why your specific code is failing.

Why you should install it:

Learn, Don't Cheat: Looking at solutions ruins the learning process. Cermonix gives you just enough of a hint to keep you thinking critically, building your actual problem-solving muscles for real interviews.
Context-Aware Debugging: You don't need to copy-paste your code into ChatGPT. Cermonix already knows what you're working on and exactly where your code is failing.
Bring Your Own Key (Complete Privacy): Cermonix uses your own Google Gemini API key. Your API key, code, and conversations are stored locally on your device and never sent to any third-party servers other than Google's API directly.
Customizable Reasoning: Switch between "Standard Reasoning" for fast, efficient hints, and "High Reasoning" for deep algorithmic analysis on complex graph or dynamic programming problems.
Stop getting stuck and start learning faster. Install Cermonix to get the guidance of a senior engineer on every LeetCode problem you solve.
