Earlier this year, a thread on Reddit’s r/cscareerquestions hit a few hundred upvotes from people documenting GhOst AI freezing mid-interview. The specific complaint wasn’t that it got caught. It was that the audio processing lagged 6-8 seconds behind the interviewer’s questions, leaving candidates staring silently at a screen that hadn’t updated yet. That’s arguably worse than going in without a tool at all.
I want to be careful here. I don’t think GhOst AI is a scam or a bad product in principle. It does what it says for a lot of people. But if you’re researching alternatives, the freezing and audio lag issues are real, documented, and worth taking seriously before your next interview.
Here’s what the landscape looks like as of mid-2026.
What “undetectable” actually means for these tools
There’s a lot of marketing language in this space that conflates different things. Worth being specific about what detection actually means, because it affects which tool is right for your situation.
Screen share detection is the most commonly advertised feature. Tools built as desktop overlays render at the OS level rather than inside a browser window, which means standard screen share tools don’t capture them. This is real and it works in most cases. Browser extensions don’t have this property, which is why browser-based tools are generally less reliable for this use case.
Audio isolation is separate. Some interview platforms use audio analysis to detect unusual background audio patterns. Most AI interview tools don’t speak audibly, they display text, so this is less of a concern than it sounds. But it’s worth checking whether the tool you pick routes audio through the system in a way that could show up in a meeting recording.
Process list hiding matters on some enterprise systems with endpoint monitoring software. A desktop app that doesn’t appear in the task manager is harder to flag. Whether your interviewer’s company uses that kind of monitoring is unknowable in advance, which is part of why this category of tool involves inherent uncertainty.
The alternatives worth considering
I’ve looked at five tools that come up most often when people are searching for GhOst alternatives. My honest read on each:
Craqly is the one I have the most direct experience with. It’s a desktop app, not a browser extension, so the screen share invisibility is genuinely solid. Response times are fast, usually under 2 seconds in my testing. The main differentiator is that it covers not just job interviews but also sales calls and meetings, which makes it more useful if you want one tool for multiple use cases. There’s a free tier to try before committing. The onboarding is thin, which is a real criticism, but the core function works.
Interview Coder is coding-interview specific. If you’re going through LeetCode-style technical screens, it’s decent. If the interview has system design, behavioral, or open-ended questions, it falls short. Narrow focus, done reasonably well.
Final Round AI has a broader feature set and has been around longer than most tools in this category. Some people report latency issues similar to GhOst. It’s worth testing on your specific setup before relying on it for a real interview. The company has been around since 2022, which in this space is relatively long-lived.
Cluely has gotten press coverage from The Verge and others in 2025 for its approach to real-time AI assistance. It positions itself more broadly than just interviews. The trade-off is that broader positioning sometimes means less specialization for the specific flow of a technical interview.
Aspect takes a different angle, it’s positioned more as a prep and coaching tool than a live-interview overlay. If you’re uncomfortable with the idea of using an AI overlay during the actual interview, Aspect is worth a look. It won’t help you in the room, but the prep tooling is solid.
Why desktop apps outperform browser extensions here
This is worth explaining because people often assume the difference is minor. It’s not.
A browser extension runs inside the browser process. Most screen sharing tools capture at the OS level, which means they capture everything, including browser windows. A desktop app with an OS-level overlay renders its own window outside the browser entirely. When a screen sharing tool scans for windows to capture, the overlay simply isn’t in the window list it sees.
This is also why GhOst’s audio issues are harder to solve. Audio processing that runs through a browser extension goes through the browser’s audio pipeline, which adds latency and is subject to browser’s background tab throttling. Native desktop audio processing doesn’t have that bottleneck.
Whether or not any of this matters to you depends on your own position on using these tools. That’s a personal decision and I’m not going to argue for or against it here. What I will say is that if you’re going to use something, use something that works reliably. A tool that freezes in the middle of a question is worse than nothing.
One thing I’m honestly uncertain about
I don’t know how these tools perform across all interview platforms. Most of my information is from Zoom and Google Meet. There are reports of variable behavior on HackerRank, CoderPad, and Karat. If you’re going into an interview on a specialized coding platform, I’d test the tool on that exact platform first, ideally in a mock scenario. Don’t assume that “works on Zoom” means “works everywhere.”
The Reddit threads and Discord servers for job seekers are probably the most current source for platform-specific reports. Those communities update faster than any blog post can.
If GhOst isn’t working for you, you have real options. Craqly is the one I’d try first if you want something that covers a broader range of interview types. Interview Coder if you’re primarily concerned with coding screens. Final Round AI if you want more setup customization. Test whichever you pick in a real video call before your next interview, not the morning of.
