Built specifically for the live coding interview — LeetCode, HackerRank, CodeSignal, CoderPad, Karat. Real-time voice, 11 programming languages, invisible to screen recording. The category-defining coding copilot.
Also called an AI coding interview assistant — the terms are interchangeable. We use both.
PhantomCode listens to the question and surfaces the approach in seconds — before you start typing. Sub-second latency where every other tool has a 3-5 second lag that breaks your rhythm.
Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, Swift, Kotlin, Ruby. Set your language per session — the copilot uses the right standard library, naming conventions, and language-specific gotchas your interviewer expects.
Two-pointer, sliding window, dynamic programming, graph traversal, segment trees, system-design trade-offs. PhantomCode names the pattern, then walks you through the implementation — you stay the one explaining.
LeetCode, HackerRank, CodeSignal, CoderPad, Karat, Codility, Mercor, online IDEs — PhantomCode is a desktop app, so it doesn't depend on the platform's UI cooperating. Same UX everywhere.
Your interviewer's recording shows your editor, your terminal, your face on camera. PhantomCode's window doesn't appear in the recording — verified across Zoom, Meet, Teams, OBS, QuickTime.
Hears the question in 50+ spoken languages. Handles when an interviewer drifts between English and Hindi/Mandarin/Spanish/etc mid-question. The technical terms come through clean.
Because PhantomCode is a desktop app — not a browser extension — it doesn’t care which platform your interviewer chose. The UX is consistent across all of them.
An AI coding interview assistant is software that runs during a live coding interview — on LeetCode, HackerRank, CodeSignal, CoderPad, Karat, or any IDE — and helps the candidate draft, debug, and explain solutions in real time. PhantomCode is the highest-real-time option in the category.
PhantomCode is a native desktop app — not a browser extension. It works alongside whatever platform the interviewer chose. It hears the question via voice, drafts the solution, and stays invisible to screen recording.
11 languages: Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, Swift, Kotlin, Ruby. The assistant uses the right standard-library functions and idiomatic patterns for each.
No. The window is invisible to screen recording and screen sharing on Zoom, Google Meet, Microsoft Teams, Webex, OBS, and QuickTime — verified.
It's a candidate-side tool — like having notes or a coach. You're still the one explaining your reasoning. The line is drawn at proctored, NDA-bound assessments, which most live coding interviews are not.
We’ve published honest comparisons against every major coding-interview tool. Including the case for stacking PhantomCode with LeetCode, not as a replacement.
