What you get inside PhantomCodeAI
Beyond the invisible overlay — the features that actually move the needle during a live round.
91 Languages & Accents
Live interviewer audio transcribed and answered in the same language across 91 Languages & Accents — Arabic, Bengali, Cantonese, English, French, German, Hindi, Italian, Japanese, Korean, Mandarin, Marathi, Portuguese, Russian, Spanish, Tamil, Turkish, Urdu, Vietnamese, and more. Bilingual modes (Arabic+English, Mandarin+English, Tamil+English, Malay+English) handle code-switching rounds.
Two AI thinking modes
Toggle Fast Think for under-pressure DSA questions where you need an answer in seconds, or Deep Think for system design and tricky algorithms where reasoning depth matters more than latency. Switch mid-round in one click.
11 programming languages
Solutions in Python, Java, JavaScript, TypeScript, C++, C#, Go, Rust, Ruby, Swift, or Kotlin — pick the language per-session and the AI matches your idioms, standard library, and naming conventions.
Resume-aware answers
Upload your resume once. PhantomCodeAI parses it and tailors behavioral answers, 'tell me about yourself' framing, and project-deep-dive responses to your actual experience instead of generic templates.
Profile-aware tone
Tell the app whether you're a student, junior, mid-level, or senior engineer — and which company you're targeting. The AI shifts code style, depth of explanation, and behavioral framing accordingly.
Custom Prompt Manager
Save your own system prompts — 'always answer in Java with comments', 'lead with complexity analysis', 'use Indian English idioms' — and switch between them per round. No more retyping the same context every interview.
How candidates actually use it
Two ways to use PhantomCodeAI
One app, two interview formats. Pick the mode that matches the round you're in — the keyboard shortcut decides.
Mode 1
Live Interview
Real-time coding rounds with a human interviewer on Zoom, Meet, or Teams. The AI listens to both sides and answers in your spoken language.
- Two-way audio transcription — interviewer + you, streamed into a WhatsApp-style chat.
- Same-language replies across 91 Languages & Accents, plus bilingual modes.
- Deep Think for system design, Fast Think for quick DSA — switch mid-round.
Best for: DSA · system design · behavioral · take-home walkthroughs
Mode 2
Online Round
Async coding tests, take-homes, or proctored assessments where no one is speaking. Capture the problem on screen, get the solution.
- Screenshot the problem with ⌘ + H — invisible to the proctor and screen share.
- Optimal solution in your chosen language, with time/space complexity and edge cases.
- Iterate with follow-up screenshots or text — the AI keeps the prior context across turns.

PhantomCodeAI is actually my buddy, I got accepted as SDE intern in product based company.
Aakash Reddy

The HLD round was the one I was dreading. PhantomCodeAI walked me through the design while I just talked — load balancer, sharding, cache layer, everything. Amazon offer two weeks later.
Vikram Iyer
Senior Software Engineer
I did the interview and got the job because of this app! It helped me so much. It gave me answers and I didn’t get caught. Yay!
Karan Verma

Did three Zoom rounds and one Google Meet with it running the whole time. Doesn’t show up on screen-share at all. By round four I wasn’t even nervous.

Everyone sleeps on the behavioral round. I used this for my Amazon Leadership Principles interview and it fed me clean STAR-format answers in real time. Bar Raiser cleared.

My recruiter started in German and switched to English halfway through. PhantomCodeAI just kept up the whole time, didn’t even have to touch it. Didn’t think that would work this smoothly.

Think
Given an array of integers, find two numbers that add up to a target sum. Return their indices.
Here's an optimal O(n) solution using a hash map:
def two_sum(nums, target):
seen = {}
for i, num in enumerate(nums):
complement = target - num
if complement in seen:
return [seen[complement], i]
seen[num] = i
Time: O(n) | Space: O(n)

What I Changed (Read these aloud)
The current solution uses nested loops, resulting in O(n²) time complexity.
We can optimize this by using a hash map to store previously seen numbers.
This reduces time complexity to O(n) with O(n) space trade-off.
Solution
def twoSum(nums: List[int], target: int) -> List[int]:
seen = {} # Value -> Index mapping
for i, num in enumerate(nums):
complement = target - num
if complement in seen:
return [seen[complement], i]
seen[num] = i
return [] # No solution found
Complexity
Time Complexity: O(n)
Space Complexity: O(n)
