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. Grillr screenshots the problem, sends it to GPT-4o vision, 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

Stealth is the point
Read this carefully
After payment your unique activation key is shown on-screen and emailed to you instantly.
The key can be activated a single time. On activation it locks to the machine you used.
Grillr binds the key to that one computer's hardware. It will not run activated on any other machine.
Because a key is bound to one machine and can only be activated once, if you reinstall your OS, reset your PC, change core hardware, or lose access to that device, the key cannot be recovered or reused. You will need to purchase a new activation key. Keep your machine and your key safe.
