Leetcode Wizard is a desktop application that uses AI to generate solutions to LeetCode-style coding problems during interviews, with a hidden interface and a web view for secondary devices.
About
Leetcode Wizard is a desktop application that uses AI to solve LeetCode-style algorithm problems during live coding interviews. The developers position it as a response to interview formats they view as disconnected from day-to-day engineering work, arguing that timed puzzle-solving does not measure real coding ability. It is worth stating plainly that the product is explicitly marketed as a tool for use during real interviews without interviewer knowledge, which raises serious ethical and professional-conduct concerns, and using it can violate interview policies and employment agreements.
After logging in, the user selects a programming language and input source, and the application analyzes the problem, proposes candidate algorithms sorted by time complexity, and then generates code, edge-case tests, and a complexity analysis. The vendor says the app runs in a hidden mode that screen-sharing and screenshot software cannot capture, is controlled through global hotkeys, and offers a companion web view that mirrors output to a second device such as a phone or tablet.
Key Features
Pricing & Fees
- Pricing: A Pro subscription costs €49 per month, which includes unlimited uses, any input source, full web-view access, and premium support with responses within 6 hours.
- Free trial: A trial version exists but limits input to problems on LeetCode.com.
- Claimed pass rate: The vendor reports a 93% pass rate in its own real-interview tests as of October 2026; this figure is self-reported and not independently verified.
- Ethical caveat: The product's core use case — receiving covert AI assistance in a live interview — constitutes cheating under typical hiring policies and can lead to withdrawn offers or termination.
Who It's For
The vendor targets software engineers and students who face LeetCode-style technical interviews, from junior candidates to staff-level engineers, particularly those applying to large technology companies. Use cases the site describes include timed coding rounds on platforms like HackerRank, CodeSignal, and Codility, including proctored sessions via the secondary-device web view. Prospective users should weigh the operational risks: many employers explicitly prohibit outside assistance during interviews, and discovery can result in rejection, rescinded offers, or blacklisting. The product is not appropriate for legitimate interview practice where the goal is to build actual problem-solving skill.
FAQ
What is Leetcode Wizard?Leetcode Wizard is an AI-powered desktop application that analyzes coding interview problems and generates solutions, tests, and complexity analysis during live interviews, with hidden mode and hotkey controls.
How much does Leetcode Wizard cost?A Pro subscription costs €49 per month; a free trial is available but limits input to LeetCode.com problems.
Which platforms does Leetcode Wizard work with?The trial supports LeetCode.com only, while the Pro version accepts any input source, including HackerRank, CodeSignal, and Codility.
Can Leetcode Wizard be detected during an interview?The vendor claims the app is invisible to screen-sharing and screenshot software and that outputs pass AI-detection checks, but these claims are self-reported and no tool can guarantee undetectable cheating.
Is using Leetcode Wizard risky?Yes. Covert assistance during interviews violates most employers' hiring policies and can result in rejected applications, withdrawn offers, or termination if discovered later.
