Ace any interview with an invisible AI co-pilot
JB FND listens to your interview audio and streams real-time answers to a separate phone you place next to your monitor. It never touches the browser, never appears on your screen, never gets caught when you share it.
How it works
Three steps. Zero traces on your screen.
The entire flow runs on a separate device. Your laptop only sees the interview — exactly what the recruiter expects.
1. Plug in
Install JB FND on your computer. It captures audio from your headphones — no microphone access, no screen recording.
2. AI listens
Our model transcribes the interviewer's questions in real time and generates concise, structured answers tailored to your role.
3. Read on phone
Answers appear instantly on your phone — clipped beside your monitor. You glance, you answer, you crush it.
Nothing renders on your laptop screen · nothing transmits over your browser · nothing the screen-share can capture
Why you won't get caught
Built for one rule: leave no trace.
Every other "AI interview helper" runs in your browser. That's the first place interviewers look. JB FND is engineered to be the opposite.
Invisible to screen-share
Nothing renders in your browser, OS, or any window. The recruiter sees only what you choose to share.
Separate device
Output lives on your phone, physically detached from the call. No screen recorder can ever capture it.
No browser extensions
Unlike competitors, we don't install Chrome plugins or overlays — common red flags interviewers actively check.
No camera, no eye-tracking risk
The phone sits at eye level beside your monitor — you naturally look at the screen, never down or away.
