Grillr is a stealth desktop overlay that hears the question or reads your screen and feeds you the answer in real time — invisible to screen recording and hidden from the taskbar.
STEALTH MODEThe problem
You know the material — but under pressure, on a timer, with someone watching, the right answer hides. Grillr sits quietly on top of your screen and gives you the exact thing to say or type, the instant you need it. No tab-switching. No second monitor. Nothing the other side can see.
The flow
Four moves, all on global hotkeys. From question to answer in seconds.
Grillr opens as a frameless overlay pinned on top of everything. It's hidden from the taskbar, disguised as a system process, and excluded from screen capture at the OS level — so screen-share and recording see nothing.
Hit the hotkey and Grillr captures the interviewer's voice straight from your system audio (WASAPI loopback) — no microphone needed. It transcribes with Whisper in real time.
Coding round or MCQ on screen? Press the capture hotkey to grab it. Long problem that runs past one screen? Scroll and grab up to 4 shots — Grillr reads them together as one problem. If the code errors, screenshot the error and it fixes its own previous answer. It runs a strong vision model and detects whether it's a coding task, a multiple-choice question, or a short answer.
A tight, interview-ready answer appears in the overlay — a full optimized solution in your chosen language for code, the correct option for MCQs, or a crisp spoken reply for behavioral questions. One key copies the code.
Default hotkeys — fully rebindable

Nothing to set up — Grillr runs top models for you. You spend credits from your license, and pick Low / Medium / High power for screenshots. Every license starts with 20 free.
Your key isn't chained to one machine — activate on any PC. One live session at a time, and your settings follow the key wherever you go.
New versions download in the background and install with one click from the title bar. No reinstalling by hand.
No graphics card needed. Screen capture runs on a background thread, so it stays responsive even on low-end laptops.
Stealth is the point
Read this carefully
After payment your unique activation key is shown on-screen and emailed to you instantly. It's yours for life.
Activate on any Windows machine — laptop, desktop, a friend's PC in a pinch. Your settings follow the key.
Only one device can run at once. Activate on a second and the first is signed out instantly — so it's always just you.
A key runs one live session at a time. Share it and every new activation kicks the previous device offline — so a key can't be used by two people at once. Your credits and settings live on the key, not the machine, so you're free to move between your own devices. Keep your key private.
