Ace your next coding interview

1. Configure your setup

Setting up Leetcode Wizard is easy. After logging in, you select the programming language and input source you would like to use. Once everything is ready, you can press solve to start.

Our desktop application can be controlled by undetectable hotkeys, which means you never have to leave the window where your coding interview is taking place.

Leetcode Wizard cannot be seen or captured by most screen-sharing software and is invisible in all screenshots. You can read more on how this is achieved in the Electron documentation. We also offer a separate web view, which can be opened from our desktop application. This will allow you to view all output on another device, e.g., your phone, tablet, or laptop. Make sure to place this second device close to your code input to prevent suspicious eye movements.

If you're taking a proctored coding interview, we recommend opening our web view on a secondary device and putting our desktop application in hidden mode. Some screen-sharing software circumvents the OS flags we set to hide our desktop application. Using our web view guarantees you'll be 100% safe.

• Built with a privacy-first mindset
• Web view for secondary devices
• Controllable with undetectable hotkeys

2. Pick an algorithm

After the AI inspects your problem, you receive a list of possible algorithms that can be used to solve the problem. These are sorted from worst to best time complexity.

We use a custom configured model that can handle any problem, known or unknown. FAANG companies refresh their questions on a regular basis and use questions that can't be found on the internet. Our model will always return at least one possible algorithm for all problems. All outputs of our model pass through our humanizer to circumvent AI detection.

• Works on any Leetcode problem
• Handles unknown problems without issue
• Responds within seconds
• Fully humanized output

3. Output

Based on the algorithm that you pick, the AI will generate code output that meets the latest standards in the chosen language, tests to show that all edge cases are handled, and a complexity analysis.

We have spent many months testing and fine-tuning our application, the AI model, and humanizer. We have extensively battle tested our application in hundreds of real coding interviews, including FAANG companies, and in over 200 mock interviews to ensure the AI model's output passes all detections used by coding interview platforms.

Our users range from students to inexperienced junior engineers to staff engineers with over 25 years of experience. As of December 2024, we have not been detected a single time during our own tests, and we’ve had a 93% (!) pass rate in our real coding interview tests.

Leetcode Wizard is invisible to all other software and can be fully controlled with global hotkeys that run at a privileged level, making them undetectable to any other software or browsers.
