Stealth isn't a single trick — it's a combination of OS-level engineering, behavior design, and privacy architecture that makes our copilot undetectable during live interviews.

Each layer works independently — together, they make the copilot virtually impossible to detect.
The copilot overlay renders in a separate process excluded from screen-sharing APIs. Even full-screen shares on Zoom, Meet, or Teams won't capture the assistant window.
We use OS-level window layering (not browser overlays) to ensure the copilot is invisible to screen recording and sharing software. The overlay auto-hides during screen-share detection.
Answer suggestions appear with natural pacing — no instant robotic responses. The copilot matches human thinking speed to avoid suspicious response patterns.
Built-in response throttling adds 2-4 seconds of natural delay. Suggestions are structured bullet points, not scripted answers, so your delivery sounds authentic.
The overlay appears in your camera's natural line of sight. No suspicious glancing at second monitors or phone screens.
The copilot positions itself near where you'd naturally look at your webcam. Adjustable placement lets you fine-tune for your specific monitor setup.
Explicit start, pause, and end controls give you full authority over when the copilot is active. Every action is predictable and auditable.
One-click activation with global hotkey support. Session logs are available for your review but never stored on our servers after the session ends.
Audio streams and transcriptions are encrypted in transit and processed in real time. Nothing is stored after your session ends.
We use TLS 1.3 for all WebSocket connections. Audio is processed as an ephemeral stream — no recordings, no transcription logs, no data retention.
The copilot doesn't inject scripts, modify browser DOM, or leave traces that proctoring software could detect.
Unlike browser extensions, our native overlay operates at the OS level. No browser fingerprint changes, no suspicious process names, no detectable network patterns.
From audio capture to stealth suggestion in under 4 seconds.
Your device's audio routing captures the interview call audio. Works with Zoom, Google Meet, Teams, phone calls — any audio source.
Audio streams to our transcription engine via encrypted WebSocket. Speech is converted to text with sub-500ms latency.
Our language model identifies the question type, extracts requirements, and maps it against your resume and preparation context.
Within 2-4 seconds, structured bullet points appear on your screen — invisible to screen sharing, positioned in your natural eye line.
Most interview assistants are browser extensions or second-screen tools. Here's why that matters.

We built the copilot with a zero-retention architecture. Audio streams are processed in real time and immediately discarded. No recordings. No transcription logs. No session replays.
Authentication is token-based with automatic expiry. Every WebSocket connection is encrypted with TLS 1.3. We don't track which questions you were asked or what answers you gave.
Your privacy isn't a feature — it's the foundation of how the system is designed. We can't access your interview data even if we wanted to, because it simply doesn't exist after the session ends.

The copilot is most valuable when you need structured thinking under pressure.
STAR-structured talking points based on your resume. No more freezing on "Tell me about a time when..." questions.
Pulls from your actual experienceArchitecture scaffolding — load estimates, component breakdowns, and trade-off frameworks for the specific problem.
Real-time scale calculationsWhen the interviewer goes off-script, the AI generates structured guidance in real time from the actual question.
No pre-built question bank neededContextual hints for follow-up questions — data structures, complexity analysis, and edge cases as the conversation evolves.
Adapts as the interview progressesAdapts suggestions for cultural communication norms across US, UK, India, and Singapore interview styles.
Region-aware response framingMaintains context across multiple rounds in the same day. Fresh suggestions for each round based on what's already been discussed.
Session continuity across roundsEverything you want to know about the stealth copilot.
No. The copilot uses OS-level window layering that is excluded from all screen-sharing APIs (Zoom, Meet, Teams, etc.). Even if you share your entire screen, the copilot overlay is not captured. We test this against every major platform update.
Our native overlay approach operates differently from browser extensions. It doesn't modify the browser DOM, inject scripts, or create detectable network patterns. However, we recommend testing with your specific proctoring setup in a practice session first.
No. Audio is processed as an ephemeral stream — it's transcribed in real time and discarded immediately. We don't store recordings, transcriptions, or session content after your session ends. Your data never persists on our servers.
Typically 2-4 seconds after the interviewer finishes their question. We intentionally add a natural delay so your responses don't seem suspiciously fast. The suggestions are bullet points, not scripts, so you deliver them in your own words.
The AI analyzes questions in real time — it doesn't rely on a pre-built question bank. Whether it's a standard behavioral question or something completely off-script, the copilot generates structured guidance based on the actual question and your resume context.
Minimal impact. Audio is compressed to Opus format at less than 100KB/s — roughly 1/50th of a typical video call's bandwidth. The copilot works reliably even on slower connections.
Currently supported on macOS and Windows desktops. The native app approach is essential for screen-share exclusion — browser-only solutions can't achieve the same level of stealth.
Set up the copilot in under 2 minutes. Use it in your next interview or practice session.
