Everything Phantum does to get you through an interview without the interviewer noticing a thing.

Sub-second responses

OpenAI Realtime generates the first token while the interviewer is still talking. No awkward lag between the question ending and your answer beginning.

Your resume, baked in

Upload a resume once and every session knows your experience. Answers reference the projects you actually worked on, not generic templates.

Job-description aware

Paste the JD or upload it. Phantum tailors answers to the role — the technologies mentioned, the seniority level, the company's stack.

Invisible overlay

A 600×60 transparent, always-on-top window. Doesn't show up in screenshares, doesn't cover the video call, doesn't scream 'I'm cheating'.

System-audio capture

Hears the interviewer directly from your system output — no awkward mic-to-mic pickup or virtual-audio driver setup.

Keys stay server-side

Nothing sensitive ships in the app binary. Session tokens are minted on our backend and rotate every minute.
