How it works?

Super simple to use. Absolutely invisible. Powered by GPT-4.

CodeRankGPT detects you are taking a HackerRank coding test and discreetly captures a screenshot of the problem.
GPT-4 processes the screenshot to solve the problem in the specified programming language.
We sent the solution to a phone, tablet or computer you choose, so that you can discreetly refer to it if you get stuck.

Absolutely Undetectable

Rest assured, CodeRankGPT is completely undetectable by HackerRank. We take this matter seriously.

✅ CodeRankGPT runs at the Computer Level

CodeRankGPT runs on the PC, Mac, or Linux level and stays completely invisible from HackerRank. It runs on your computer, not in the browser, so HackerRank's cheat detection can't see it.
✅ Displaying the Solution on a Separate Device

The solution to the coding test will be sent and displayed on another device you choose (mobile phone, tablet, or another computer). In case the interviewers ask you to share your screen, you will be safe.
✅ You can't Copy-Paste the solution

HackerRank's anti-cheat system is capable of detecting contents in your clipboard and notice if you paste code. However, since the solution is displayed on a separate device, you can refer to it when needed and manually type it out, ensuring you stay undetected.
✅ No Tab Switching needed

HackerRank's anti-cheat system can flag tab-switching during a coding test as suspicious behavior. With the solution displayed on a different device, you can discreetly refer to it without the need to switch tabs, avoiding any red flags.
✅ You don't need to copy the problem statement

HackerRank's anti-cheat system can monitor your clipboard for copied content, including if you copy the problem statement. Our solution bypass this by taking a screenshot of your entire screen and automatically identifying the problem statement, ensuring you remain undetected.
✅ HackerRank window always focused

HackerRank's anti-cheat system tracks whether the browser window with the coding test is active or not. Frequent unfocusing could be flagged as suspicious. However, with the solution on a separate device, your test window remains consistently active, eliminating the risk of suspicion.
