Install, activate, plug in your AI provider, and walk into your interview ready. Takes about 5 minutes to set up.
Start here
Grillr is a stealth desktop overlay for Windows. During an interview or test it can (a) listen to the question from your system audio and (b) read a problem straight off your screen, then feed you a tight answer — all in a window that's excluded from screen recording and hidden from the taskbar.
Grillr runs the AI for you and you pay per use in credits — nothing to set up, no accounts to wire. Just buy credits and go.
Step 1
Step 2
Paste the license key from your purchase email into the activation window and hit Activate. That's it — you're in.
Use it on any device — one at a time. Activate the same key on a laptop, a desktop, wherever. Only one can run at once: activate on a new machine and the previous one is signed out instantly. Your credits and settings live on the key, so they follow you. Don't have a key yet? Get one for ₹699 →
Step 3
Grillr runs the AI for you. You pay per use in credits (1 credit = ₹1), and every license starts with 20 free. Everything lives in Settings → Credits.
Your live credit balance shows right on the main screen (⚡ chip) and in Settings → Credits. You're only charged for what each answer actually uses. Credits never expire. Recharge on your license key (min ₹100) at grillr.in/recharge.
Pick a power level for screenshot solving — Low / Medium / High. Higher = a smarter model (and a bit more credits per solve). Set it in Settings → Credits, or cycle it instantly with Ctrl + ↑ — the current level shows in the title bar. Voice answers use a balanced model automatically.
Step 4
Step 5
Press M to start capturing (system audio by default — no mic needed), press M again to stop. Grillr transcribes the question and shows a short, interview-ready answer.
Press I to add a screenshot to the batch. A long problem can run past one screen — scroll and press I again for each part (up to 4 shots). A thumbnail tray shows what you've grabbed; ✕ drops any bad one. When you're done, press O to solve — Grillr reads all the shots together as one continuous problem and returns a single answer. Press C to copy any code block.
Just one screen? Press I once, then O — that's a normal single-shot solve.
Grillr remembers the answer it just gave. If the solution fails, capture the error message or failing test (press I, then O) and Grillr fixes its previous code against that error and returns the complete corrected solution. It only iterates when the new capture is clearly feedback on the last answer — an unrelated new problem is solved fresh. Want a clean slate? Press Numpad . to clear the screenshots and reset the context.
Answers appear in the overlay. It stays on top, doesn't take focus when you click it, and is invisible to screen recording.
Reference
All shortcuts are global and fully rebindable in Settings → Shortcut Keys.
| M | Start / stop voice recording |
| I | Add a screenshot to the batch |
| O | Solve the captured screenshots |
| Numpad . | Clear screenshots / start a fresh question |
| Ctrl + ↑ | Cycle answer power (Low / Medium / High) |
| C | Copy code from the last answer |
| Numpad * | Enable / disable shortcuts |
| Numpad − | Panic hide (invisible + click-through) |
| Insert | Restore the hidden window |
Important
The window is excluded from screen capture at the OS level (Windows 10 2004+), hidden from the taskbar, and disguised as a system process.
Panic hide with Numpad − (fully invisible + click-through); restore with Insert.
⚠️ Don't open Settings during a proctored session. Opening Settings makes the window focusable so you can type — which can register as clicking away from your exam tab. Configure everything before you start; during the session, use only the global hotkeys (which never steal focus).
Fixes
Top up at grillr.in/recharge (minimum ₹100). Your live balance shows in the title bar next to the power level.
Bump the power up with Ctrl + ↑ (Low → Medium → High) — the current level shows in the title bar. Higher spends a few more credits per solve.
Press I to grab each screenshot (up to 4), then O to solve them. Make sure your internet is on — Grillr runs the AI in the cloud.
Your key runs one session at a time — if it says 'activated on another device', it was used elsewhere. Just re-activate here to take it back (which signs the other device out).
Click More info → Run anyway. Grillr is unsigned but safe; the disguise + capture-exclusion are intentional features.
Legal
One key is a lifetime license for a single user — usable on any device, one live session at a time, and not for sharing between people (activating elsewhere signs out the previous device). Credits are non-refundable and don't expire. Grillr is sold for educational and personal use; you're responsible for complying with the policies of any test or interview you take.
