Your interview
assistant. Invisible
to cameras.
The interviewer asks. The answer appears on your phone. Your screen stays completely blank to any recorder.
Live answer flow
How it works
Three steps.
Completely invisible.
Your computer listens
The desktop app runs invisibly in the background. It captures the interviewer's audio — from your meeting tab or a microphone — using the source you choose.
AI answers in real time
Groq Whisper transcribes the question instantly. Llama 3.3 generates a detailed, contextual answer — behavioral, coding, system design, anything. Answer in under a second.
Answer appears on your phone
Pair your phone with a QR code — takes 5 seconds. The answer appears as a scrolling conversation. Your computer screen shows nothing suspicious.
Features
Built for the real thing.
Invisible to screen recording
The desktop app uses OS-level content protection (WDA_EXCLUDEFROMCAPTURE on Windows). Recorders, screen shares, and proctoring tools see a blank window.
Behavioral & coding questions
STAR-formatted answers for behavioral prompts. Step-by-step algorithm walkthroughs with working code for technical questions. Context carries across follow-ups.
Works with any meeting tool
Zoom, Google Meet, Microsoft Teams, any browser tab — capture the audio source you choose. No app integrations required.
Answers in under a second
Pre-computed bank covers common questions instantly. Groq Llama handles novel questions in ~1s. The answer is ready before you even start speaking.
Runs silently in background
Close the window and it hides to the system tray. Your phone stays connected throughout the interview without the app ever visible on your desktop.
Your phone is a second screen
Pair in 5 seconds with a QR code. The answer conversation scrolls on your phone — the only screen that matters in the interview.

Testimonials
They got the job.
“I was bombing FAANG behavioral rounds consistently. After three sessions with Quelo I started actually landing the answers — specific, structured, confident. Got the offer.”

SWE · Google
“The coding question answers are insane. Not just 'use a hashmap' — full walkthrough, complexity, working Python. I could glance at my phone and just speak the approach.”
Priya Sharma
Backend Engineer · Stripe
“I panicked when the interviewer asked a system design question I'd never seen. The answer appeared on my phone in under a second. ASCII diagram, key tradeoffs, everything. I crushed it.”
David Chen
Staff Engineer · Atlassian
“Setup takes literally 5 seconds. Scan the QR, phone is paired. The fact that my screen is completely blank on their end — that's the killer feature. No stress.”
Neha Verma
Product Manager · Razorpay
“Follow-up questions are handled so well. It remembers the entire conversation context. When they asked 'can you elaborate on that?' it knew exactly what 'that' was.”
James O'Brien
ML Engineer · OpenAI
“Worth every dollar. I used to freeze on weakness questions. Now I have a crisp, honest-sounding STAR answer ready before I've finished nodding at the question.”

Is my screen really invisible?
