HackerRank Assistant for Live Coding Interviews
Real-time AI HackerRank assistant with phone mirroring and deep
stealth for timed coding tests.
Timer ticking. Browser locked. No IDE, No StackOverflow.
CTRLpotato
quietly captures the full HackerRank problem, thinks for you in the
background, and gives you human-sounding explanations and code you can
actually work with.
Why HackerRank coding interviews feel brutal
Timer pressure + blank brain
You get 60–90 minutes for multiple problems. One tricky bug early and the clock owns you. It’s hard to think clearly under a live countdown.
Locked environment, no safety net
No IDE, no StackOverflow, no second tab with ChatGPT. The more “normal” tools you depend on day‑to‑day, the weirder this setup feels.
Proctoring & recordings
Screens can be recorded or monitored. Browser extensions, visible overlays, and second windows are risky. You need help that stays out of sight.
How CTRLpotato works on HackerRank
Capture the entire problem with one key
Use F‑keys to screenshot the full HackerRank task, a specific region, or just the description text.
Stack multiple captures — problem statement, examples, and even your draft code — into one context buffer before asking.
Get coding‑focused answers in your language
Press F4. First you get bullet‑point hints, then a complete solution with time/space complexity and a spoken‑style explanation.
Answers default to your preferred language (Python, Java, JS, C++, and more), and you can regenerate into a different language with one click.
Keep answers off‑screen when it matters
CTRLpotato is designed to stay out of your main screen. When things get strict, you can mirror everything to your phone instead.
Trigger screenshots, answers, model switches, and follow‑ups from your phone while your browser stays focused on HackerRank.
Built for HackerRank and coding platforms
🧠 Language‑aware code generation
- Auto-detect problem language.
- Lock preferred language (Python, Java, JS, C++, C#, Go…).
- One‑click regenerate solutions in other languages.
📈 Time & space complexity included
- Every solution comes with Big‑O time and space analysis.
- Highlights tradeoffs between brute‑force and optimal answers.
- Makes it easier to justify your approach if someone asks.
Use it during practice to internalize patterns like two pointers, sliding window, and BFS/DFS.
🧺 Rolling context buffer
- Layer problem text, examples, error messages, and your partial code.
- Send everything at once for one coherent answer.
- Follow up on the last answer without losing context.
Perfect for multi‑part HackerRank questions or when you discover new constraints after the first attempt.
⚡ Model switching tuned for timers
- Quickly switch between fast and deep-thinking AI models depending on the question difficulty.
You stay in control: pick the tradeoff between “fast enough” and “thinks deeper about edge cases”.
🫥 Stealth‑focused design
- Desktop UI designed to stay out of your shared screen.
- Optional phone mirroring to keep answers off‑screen.
- Deep obfuscation to reduce obvious traces on your machine.
CTRLpotato is built to minimize visual traces.
🌍 Works beyond HackerRank
- Works with coding sites like LeetCode, CodeSignal, Codility, Zoom, Teams, and more.
- Supports 10+ spoken languages for flexible use.
Build one workflow that covers both your practice platform and the actual interview setup.

FAQ: CTRLpotato and HackerRank
Does CTRLpotato work on HackerRank coding interviews?
Yes. CTRLpotato can capture HackerRank‑style problems via screenshots, text selection, or audio, then return coding‑focused hints, full solutions, and complexity notes in your preferred language.
Can HackerRank detect CTRLpotato?
CTRLpotato is designed to minimize on‑screen traces and keep its UI out of your main screen. You can also mirror answers to your phone so nothing extra appears next to the test.
Is this a way to “cheat” on HackerRank or other coding tests?
No. Take it as a stress buffer. It helps you structure your thinking, clarify your approach, and stay calm under HackerRank’s tight timer. You're still writing and owning your solution; CTRLpotato just ensures pressure doesn't overshadow your skill.
Which programming languages does it support for HackerRank problems?
CTRLpotato works well with common languages used on HackerRank: Python, Java, JavaScript/TypeScript, C++, C#, Go, and more. You can set a preferred default language and regenerate solutions into another when needed.
Will answers sound obviously AI‑generated?
No. CTRLpotato’s answers read like real, thoughtful code, clear logic, human naming, and natural structure. Each solution is original and easy to tweak, with concise comments that explain the reasoning instead of dumping boilerplate.
Does CTRLpotato only work with HackerRank?
No. The same workflow works on other coding platforms (LeetCode, CodeSignal, Codility, etc.) and live coding rounds on Zoom or Teams.
Tired of blanking out mid-HackerRank test?
Stay calm, think clearly, and write code that actually feels like yours.
CTRLpotato gives you instant structure and clean solutions so
pressure doesn’t win.
