Leetcode Wizard targets a specific, uncomfortable moment: the technical interview where a familiar-feeling problem turns out to be one you have never seen. The desktop app runs invisibly on top of the interview environment. After you select your programming language and input source, the model inspects the problem and returns a ranked list of candidate algorithms ordered from worst to best time complexity, followed by code in the chosen language along with edge-case tests and a complexity analysis.
Control is deliberately hands-off. Global hotkeys operate at a privileged level so they remain invisible to browsers and other software, and the window is designed not to appear in screenshots or screen-sharing captures. For proctored sessions, a companion web view can mirror all output to a phone, tablet or second laptop, letting the desktop app stay hidden while the candidate reads from another device. All model output is passed through a humanizer to reduce AI-detection signals, and the vendor reports parity testing against hundreds of real interviews, including FAANG loops, plus more than 250 mock interviews.
The product covers any problem rather than a fixed database, including questions that do not exist publicly, and supports input from platforms such as LeetCode, HackerRank, CodeSignal and Codility on the paid tier. Pricing is a single Pro subscription at €49 per month with free updates; a free trial is available, though trial input is limited to LeetCode.com. Because the tool is designed to be used undetected in assessments, candidates should weigh employer policies and platform terms before relying on it.
