Ghost Engineer

Ghost Engineer has a free demo, though the demo gets limited access to the latest AI models and does not cover everything the full version does.

It is an AI interview assistant for coding that gives you on-screen help in real time while you work through a technical interview.

The makers say it is completely undetectable, which is the whole pitch, and you should think carefully about whether using it fits the rules of any interview you sit.

Ghost Engineer can offer hints or complete solutions, so you choose how much help to take.

It handles a wide array of programming languages and several human languages.

The idea is that you spend your time explaining your reasoning instead of wrestling with syntax.

The company says it does not store your data, which matters for a tool running during something this sensitive.

There are two practical catches.

Ghost Engineer currently runs only on macOS, and it needs an internet connection to work.

Windows and Linux users are out of luck for now.
