## Leetcode Wizard

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.

**Pricing & Plans:** Paid subscription. A Pro plan is listed at €49 per month and includes unlimited uses, any input source, the secondary-device web view, priority AI responses and premium support, with future updates included. A free trial exists but restricts input to LeetCode.com.

- **Algorithm suggestions in seconds:** The model inspects the problem and returns several viable algorithms sorted from worst to best time complexity, including for problems that are not published anywhere.
- **Code, tests and complexity analysis:** Pick an algorithm and receive idiomatic code for your chosen language, edge-case tests and a written complexity analysis within seconds.
- **Stealth desktop overlay:** Undetectable global hotkeys run at a privileged level, and the window is designed to stay invisible in screenshots and screen-sharing software.
- **Secondary-device web view:** Mirror every output to a phone, tablet or second laptop so you never need to open anything on the machine being proctored.
- **Humanized output:** All responses pass through a humanizer layer intended to strip patterns that AI-detection tools look for in generated text.

**Strengths:** Returns algorithms, code, edge-case tests and complexity notes in one pass; Undetectable hotkeys and a separate web view give genuine operational flexibility; Not limited to a fixed problem database, so fresh or unpublished questions are still handled; Trial available, and the Pro plan includes all future updates

**Limitations:** Explicitly positioned as interview cheating, which conflicts with most employer and platform policies; Uses a subscription rather than a one-time purchase, at €49 per month; The free trial only accepts input from LeetCode.com, so other platforms need Pro

## Marble - LeetCode Tutor

Marble is a lightweight Chrome extension for people grinding LeetCode who want to learn the reasoning behind solutions rather than simply copy them. It injects a small circular pin onto the LeetCode problem page; clicking it opens an AI tutor that walks you through the problem interactively. The approach is deliberately Socratic: the tutor helps you break down the prompt, propose an approach, and translate that plan into working code.

**Pricing & Plans:** Free browser extension. No subscription or paid tiers are advertised on the Chrome Web Store listing.

- **Guided walkthroughs on any problem:** Open any LeetCode problem and Marble follows a structured three-stage routine: understand the problem, build a plan, then implement it. The flow mirrors what interviewers expect to hear in a technical screen.
- **Works across languages:** Help is generated in the language of your choice, so you can keep solving in Python, Java, C++, JavaScript, Go, or whichever stack you interview in.
- **Builds interview thinking, not answers:** Marble coaches rather than solves, nudging you toward the right data structure or edge case instead of pasting a finished solution, which reinforces pattern recognition over time.
- **Lightweight in-page extension:** Activate the tutor from a small pin button directly on the LeetCode problem page, with no separate dashboard or tab juggling.

**Strengths:** Free to install and use directly in the browser; High user rating (5.0 across 23 ratings at time of review); Coaches understanding instead of handing over solutions; Works with any programming language you solve in
