Question 1

What is Phantom Code?

Accepted Answer

Phantom Code is an AI-powered desktop application that provides real-time assistance during technical coding interviews. It helps you solve DSA problems, system design questions, and more with instant AI-generated solutions. Available for macOS (Apple Silicon & Intel) and Windows.

Question 2

Is Phantom Code undetectable?

Accepted Answer

Yes. Phantom Code is designed to be invisible to screen-sharing and screen-recording software. It runs as an overlay that cannot be captured by tools like Zoom, Google Meet, Microsoft Teams, or any proctoring software. It does not appear on your dock or in Activity Monitor.

Question 3

How does Phantom Code work?

Accepted Answer

Simply take a screenshot of your coding problem using the app's hotkey. The AI analyzes the problem — whether it's DSA, system design, SQL, or conceptual — and generates a complete solution with approach explanation, optimized code, and complexity analysis. It streams the response in real-time so you can follow along.

Question 4

What platforms does Phantom Code support?

Accepted Answer

Phantom Code works on macOS (both Apple Silicon M1/M2/M3/M4 and Intel) and Windows. It's compatible with all major interview platforms including HackerRank, CodeSignal, LeetCode, CoderPad, and any browser-based coding environment.

Question 5

What programming languages are supported?

Accepted Answer

Phantom Code supports Python, Java, JavaScript, TypeScript, C++, C#, Go, Rust, Ruby, Swift, and Kotlin. You can set your preferred language in settings and the AI will generate solutions in that language.

Question 6

How much does Phantom Code cost?

Accepted Answer

Phantom Code offers flexible plans: Basic at ₹999/month, Pro at ₹2,499/month, and Elite at ₹11,999/year. Each plan includes real-time AI assistance, multi-language support, and screenshot-based problem solving. The Pro and Elite plans include additional credits for more questions.

Question 7

Can Phantom Code solve LeetCode problems?

Accepted Answer

Absolutely. Phantom Code excels at solving LeetCode-style DSA problems. It provides optimal solutions with step-by-step approach explanations, time and space complexity analysis, and well-commented code — exactly what you'd present in an interview.

Question 8

Does Phantom Code work for system design interviews?

Accepted Answer

Yes. Phantom Code handles system design (HLD), low-level design (LLD), database design, and SQL problems. For design questions, it uses a bottom-up approach: explaining key concepts, walking through the design step-by-step, and discussing trade-offs and scalability.

Question 9

Is there a free trial?

Accepted Answer

Phantom Code offers a trial experience so you can see how it works before committing. Check our subscription plans page for the latest offers and pricing details.

Question 10

How is Phantom Code different from Interview Coder?

Accepted Answer

Phantom Code offers several advantages: more affordable pricing with INR-based plans, support for personalized AI prompts tailored to your experience level and target role, two AI modes — Deep Think for thorough analysis and Fast Think for quick answers — and a profile-aware system that adapts responses based on whether you're a student, job seeker, or professional.

Question 11

How is Phantom Code different from Final Round AI?

Accepted Answer

Unlike Final Round AI which focuses broadly on all interview types, Phantom Code is purpose-built for technical coding interviews. It provides specialized DSA solutions, system design breakdowns, and code-first responses optimized for software engineering interviews at FAANG and top tech companies.

Question 12

How is Phantom Code different from UltraCode AI?

Accepted Answer

UltraCode AI charges $899 for lifetime access with no monthly option. Phantom Code offers flexible monthly plans starting at ₹999/mo, two AI modes (Deep Think + Fast Think) instead of a single mode, personalized prompts that adapt to your experience level, and a custom prompt manager. No need to gamble $899 upfront.

Question 13

How is Phantom Code different from Parakeet AI?

Accepted Answer

Parakeet AI is a general-purpose interview assistant that transcribes and answers HR/behavioral questions. Phantom Code is purpose-built for coding interviews — it solves LeetCode/DSA problems, handles system design, generates optimal code in 11 languages, and runs as an undetectable desktop overlay instead of a browser-based web app.

Question 14

Can I customize the AI's behavior?

Accepted Answer

Yes. Phantom Code includes a Prompt Manager where you can create custom prompts to control how the AI responds. You can also set your user profile (student, job seeker, professional) and target role (software engineer, data scientist, etc.) — the AI automatically adapts its tone, depth, and focus based on your profile.

Question 15

What AI modes does Phantom Code offer?

Accepted Answer

Phantom Code offers two modes: Deep Think for thorough step-by-step analysis (great for system design and complex DSA), and Fast Think for quick, concise answers under time pressure. You can toggle between modes with one click depending on the situation.

Question 16

Can I get a refund?

Accepted Answer

You can request a refund within the first 24 hours of plan activation, provided you supply video evidence showing that the software is not functioning on your computer. Contact customer-care@phantomcode.co for refund requests.

Question 17

Is Phantom Code safe to use?

Accepted Answer

Phantom Code is a legitimate software tool. Your data is processed securely, and we do not store your interview screenshots or problem content on our servers beyond the active session. All communication is encrypted.

Question 18

How do I install Phantom Code?

Accepted Answer

Download the installer from our website for your platform (Mac ARM, Mac Intel, or Windows). Run the installer, sign in with your email, and you're ready to go. The entire setup takes less than 2 minutes.

Question 19

Does Phantom Code work with online assessments?

Accepted Answer

Yes. Phantom Code works seamlessly with online assessments (OAs) from HackerRank, CodeSignal, LeetCode, HackerEarth, and other platforms. Since it runs as an invisible overlay, it doesn't interfere with any browser-based assessment tools.

Question 20

Can interviewers detect Phantom Code?

Accepted Answer

No. Phantom Code is specifically designed to be undetectable. It doesn't show up in screen shares, screen recordings, Activity Monitor, or dock. It's click-through transparent, meaning interviewers cannot see or interact with it even if they look at your screen.
