Step-by-Step Guide

How It Works

1. Generate a Challenge

Select your difficulty level and let our AI generate a unique coding problem for you on the spot. No more memorizing LeetCode questions.

2. Code in the Browser

No setup required. Write your solution in a plain-text environment to simulate a real whiteboard interview without the crutch of syntax highlighting or autocomplete.

3. Run & Test

Execute your code against multiple test cases to verify correctness. See runtime errors or output logs instantly.

4. Virtual Senior Engineer Review

The AI doesn't just check if your code passes; it tells you how to write it like a Lead Dev. Get suggestions on clean code, edge-case handling, and memory efficiency.

The Refactor Suggestion: After your code passes, see exactly how a Principal Engineer would rewrite it for readability and performance.

Why Use This Tool?

Enhance your preparation with features designed to give you the competitive edge.

Zero Environmental Setup

Start coding immediately without configuring local environments or compilers.

Intelligent Hints

The AI acts like a senior engineer, guiding you to the solution rather than just giving it to you.

Interview Pressure Mode

Enable 'Interview Mode' to hide the run button, set a 45-minute countdown, and have the AI ask you to explain your logic out loud while you code.

Multi-Language Support

Practice in your preferred language: Python, JavaScript, Java, C++, and more.

The 'Brutal' Senior Refactor

User: "My solution passes the tests, but is it production-ready?"

AI Mentor: "Your logic is correct, but you're using stateful global variables which could cause race conditions in a concurrent environment. Additionally, if you refactor this to use bitwise operations, you could process the buffer directly and reduce memory overhead by ~15%."
