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.
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.
We’ve published honest comparisons against every major coding-interview tool. Including the case for stacking PhantomCode with LeetCode, not as a replacement.
