How to Use AI Effectively for LeetCode practice — And During Interviews

In recent years, AI tools have become incredibly powerful at solving coding problems. Whether you're grinding LeetCode for an upcoming tech interview or trying to level up your problem-solving skills, AI can be a great companion — if used correctly.

In this post, we'll explore:

• The best ways to use AI when practicing LeetCode
• Common pitfalls to avoid
• A stealthy tool called Ghostcoder that lets you use AI even during interviews without detection

Using AI to Practice LeetCode (Without Cheating Yourself)

AI assistants like ChatGPT and GitHub Copilot can drastically accelerate your learning — but they can also hinder it if you become too reliant. Here’s how to use them wisely:

✅ Use AI to:

• Understand problems: Paste in a problem description and ask for a breakdown of what it's really asking.
• Get hints: Instead of full solutions, ask the AI to give you a nudge in the right direction.
• Debug your code: Share your code and error message; let the AI help spot logic bugs or syntax issues.
• Learn multiple approaches: Ask the AI to explain both brute-force and optimized solutions.
• Study patterns: Request examples of common patterns (e.g., sliding window, binary search) in action.

❌ Avoid using AI to:

• Solve every problem for you from scratch
• Copy-paste answers without understanding
• Skip writing your own code or test cases

AI is like a tutor — not a substitute for doing the work. Use it to learn, not just to get through problems faster.

Using AI During Interviews — Without Getting Caught

Most coding interviews require screen sharing or live coding in a shared environment. This has made it hard for candidates to leverage AI assistance — until now.

Solution: Ghostcoder

Ghostcoder is a tool that helps you use AI assistance invisibly during interviews. Here’s how it works:

• 🕵️ Invisible on Screenshare: Ghostcoder runs in a floating window that's completely invisible to the interviewer during screen sharing.
• 🧠 Clickless & Keyless AI Help: Just hover or use a shortcut — no visible interaction needed.
• 🔐 Secure and Private: It uses your own OpenAI/Gemini/Anthropic API key, and no data ever leaves your machine.
• 💸 No subscriptions: One-time purchase. Lifetime access.

Whether you’re stuck on a recursive edge case or unsure how to optimize your algorithm, Ghostcoder gives you just enough of a boost — without raising any flags.

Final Thoughts

AI is changing the way we prepare for and perform in coding interviews. Used correctly, it's a powerful ally — and with tools like Ghostcoder, you don’t have to leave it behind just because you're being watched.

P.S. Remember that ethics matter. Ghostcoder is a tool — how you use it is up to you. Aim to learn, grow, and build your confidence, not just get the job by any means necessary.
