Nothing between you
and the answer.
ZeroLayer AI rehearses you on the questions you’ll actually get — then rides along in the real interview with quiet, structured guidance. Answers, code, and coaching, generated on your Mac and never uploaded.

“Tell me about a time you led under pressure.”
Start with the outcome, then rewind. When checkout started dropping 1 in 8 payments the week before launch, I owned the war room — traced it to a retry bug and recovered 38% of failed charges in two days.▍

How it works
Prepare like it matters. Perform like it’s easy.
ZeroLayer is two products in one flow: a rigorous prep coach before the interview, and a calm real-time copilot during it.
Set the scene
Paste your resume + the job description, pick the round, and ZeroLayer tailors itself to the exact interview ahead.
Practice until it’s easy
Run realistic mock interviews, get scored, and review a recap that turns weak answers into confident ones.
Walk in, locked in
Start the copilot before your call. It listens, and quietly feeds you the structure, answer, or code the second you need it.
Invisible in the call. Right when you need it.
The interviewer asks. ZeroLayer hears it and streams your answer into an overlay only you can see — hidden from screen-share, recordings, and proctoring software.

Features
Everything the hard interviews demand.
Built specifically for behavioral, coding, and system-design rounds — not a generic meeting notetaker pointed at interviews.
Real-time guidance
ZeroLayer listens, detects the question the moment it’s asked, and streams a crisp, structured answer into a glanceable overlay — STAR-framed for behavioral, to-the-point for everything else.
- Question detection, not key-spamming
- Structured + skimmable
- Follows the conversation thread
Coding & system-design copilot
For technical rounds it reads the problem, lays out the approach, names the time/space complexity, and writes working code in your language — plus battle-tested frameworks for system design.
- Python · Java · C++ · JS & more
- Complexity + edge cases
- System-design templates
Realistic mock interviews
Practice mode generates role-, company-, and JD-aware questions, runs a full mock, then hands you a post-interview recap that scores your answers and shows exactly what to tighten.
- Tailored to the job
- Scored + actionable recap
- Rehearse until it’s muscle memory
Private by design
Transcription happens on your Mac with on-device Whisper. The overlay is a personal window that stays out of screen-shares and recordings — there’s no bot in the call and nothing parked on someone else’s server.
- On-device speech-to-text
- Off screen-share & recordings
- No meeting bot, ever
Tuned to you
Drop in your resume and the job description once. Answers reference your real experience and sound like you — not a generic script a panel has heard a hundred times.
- Resume + JD aware
- Answers in your voice
- Remembers your setup
A quiet, glanceable HUD
A frameless overlay you can dim, move anywhere, and read in a half-second glance. Designed to be felt, not seen — so you stay present with your interviewer instead of staring at notes.
- Adjustable opacity
- Always where you need it
- Zero clutter

Private isn’t a feature. It’s the foundation.
Every competitor talks about being “invisible.” None of them can say your audio never leaves your machine. ZeroLayer can — because it’s the only design we’d trust with our own interviews.
On-device transcription
Your interview audio is transcribed locally with Whisper. It’s never streamed to us or anyone else.
Off screen-share & recordings
The overlay is a private window that stays out of shared screens and call recordings. You control its opacity.
No bot, no data sold
Nothing joins your call as a guest, and we never sell or train on your conversations. Your prep is yours.
Calmer interviews. Better answers.
“I walked into my system-design round actually calm for the first time. It kept me structured without ever sounding scripted.”
“The coding copilot is unreal — approach, full solution, and complexity in one glance. I stopped freezing on the hard ones.”
“A week of mock behaviorals and my STAR stories were tight and specific. The recap told me exactly what to sharpen.”

FAQ
Straight answers.
ZeroLayer is built for preparation and real-time support — the same way notes, a second monitor, or a mock-interview coach help you perform at your best. You’re responsible for using it within the rules of any specific interview or assessment. We deliberately lead with prep and coaching, because that’s where it’s most valuable and always fair game.
Transcription runs on-device with Whisper, so your interview audio never gets uploaded. Answer generation runs through your authenticated account so we can keep models fast and secure — we don’t sell or train on your conversations.
ZeroLayer renders as a private overlay that stays out of screen-shares and recordings, and there’s never a bot in the call. You control its opacity and position, so it’s there for you and invisible to everyone else.
Any of them. ZeroLayer listens to your call’s audio, so it works across Zoom, Google Meet, Microsoft Teams, phone screens, and live coding platforms — no integrations to install.
ZeroLayer AI is macOS-first today (macOS 14+). Windows is on the roadmap — join the list and we’ll tell you the moment it ships.
Yes. Pro is month-to-month with no lock-in, and you can manage or cancel your subscription from your account dashboard in two clicks.
