Undetectable AI interview assistant: 100% invisible on screen share

Key takeaways

• The operating system itself keeps the overlay out of screen capture, so the call app never receives it.
• The overlay stays out of the taskbar and the Dock, and on a Mac it is hidden from Mission Control.
• Nothing joins the meeting and nothing is installed in your browser: the participant list looks exactly as usual.
• Before the interview, share your screen on a test call with yourself and look at what the other side sees.
• 15 free minutes when you first sign in, no card. Then pay-once packs from ₹299, with no subscription.

What is an undetectable AI interview assistant?

An AI interview assistant listens to the questions in a live interview and suggests what to say. "Undetectable" means the help reaches only you: it doesn't appear on your shared screen, in the meeting's participant list or in the call's audio.

Tools get there in three different ways, and only one of them keeps everything off the call.

How does Helpwing stay invisible on screen share?

Screen sharing is not something Zoom or Teams does on its own. The call app asks the operating system for a picture of your screen, many times a second, and sends that picture to the other side. Helpwing marks its overlay so the operating system leaves it out of that picture.

• On Windows, the overlay carries the display-affinity flag WDA_EXCLUDEFROMCAPTURE. Microsoft's documentation describes it plainly: the window is shown on your monitor and does not appear anywhere else. The flag arrived in Windows 10 version 2004, which is why Helpwing needs build 2004 or later.
• On macOS, the overlay uses window content protection, the system setting that tells macOS not to share a window's contents. It is also hidden from Mission Control.
• On both, the overlay has no taskbar button and no Dock icon, so a full-screen share doesn't show a stray Helpwing icon either.

The audio side is just as quiet. Helpwing hears what your speakers or headphones play, which is the interviewer's voice, and turns it into text on your screen. It sends nothing into the call: no bot, no extra audio, no message in the chat.

What can the interviewer see when you share your screen?

Here is what the other side sees in each app and share mode while the Helpwing overlay is open on your screen.

The overlay is never in the share. A window you share stays visible to the interviewer even when the overlay sits on top of it on your monitor.

What else can and can't they see?

That last row matters more than any software. You can move the overlay with ⌘ or Ctrl plus the arrow keys, so place it just under your camera and glance at it the way you would at your own notes.

How do you set it up on Mac?

1. Download and sign in. Get Helpwing for macOS 14.2 or later, on Apple silicon or Intel, from the download page. Sign in and you get 15 free minutes, with no card.
2. Allow audio access. When macOS asks, allow the screen and system audio recording permission so Helpwing can hear the call. Turn on the microphone too if you want your own side transcribed.
3. Tune Interview. Add the company, your resume, the job description and any notes. Start the session when the call begins.

How do you set it up on Windows?

1. Download and sign in. Helpwing runs on Windows 10 (build 2004 or later) and Windows 11, 64-bit. Get it from the download page and sign in.
2. Check system audio is on. Helpwing listens to what your computer plays, so the interviewer's voice reaches it through your speakers or headphones. You can add your microphone as well.
3. Tune Interview. Add the company, your resume, the job description and notes, then start the session when the interview starts.

Answers come in fixed shapes. A spoken question gets a "Say this" line of one to three sentences, then three to five key points, and sometimes an "If they dig deeper" line. Behavioural questions come in STAR form. A coding problem from a screenshot gets the approach, the code, its complexity and edge cases. System design gets the design in points plus one diagram.

How do you test it before your interview?

Don't take any tool's word for it, ours included. Five minutes of testing tells you exactly what your interviewer will see.

1. Start a call with yourself in the app the interview uses: a Zoom meeting, a Google Meet or a Teams Meet now.
2. Join the same call from your phone so you see what a second person sees.
3. Open Helpwing so the overlay sits on your screen.
4. Share the way you'll share in the interview: entire screen, one window or a tab. Look at your phone.
5. Play a short video of someone asking an interview question and check that an answer appears on your laptop, and nothing new appears on your phone.

If the overlay ever shows up in the test, quit and reopen Helpwing, and on Windows check that you are on build 2004 or later. Test again the day before, after any operating system update.

It is built for live interviews. It is not for exams, online assessments or proctored tests.

Questions people ask

Is Helpwing really undetectable on screen share?

Yes. The overlay is 100% undetectable on screen share: Windows and macOS leave it out of the picture they hand to Zoom, Google Meet and Microsoft Teams, so it isn't in an entire-screen, window or tab share. Run a test call with yourself to see it.

Will the overlay appear in a meeting recording?

No. A meeting recording saves what the call app received, and the call app never received the overlay. Your camera and voice are recorded as usual.

Does Helpwing join the meeting as a bot?

No. Nothing joins the call. Helpwing is a desktop app that hears the call through your computer's audio, so the participant list shows only the people who were invited.

Can the interviewer see Helpwing in my taskbar or Dock?

No. The overlay has no taskbar button on Windows and no Dock icon on a Mac, and it is hidden from Mission Control. If you share your entire screen, there is no Helpwing icon to see.

Which computers does it run on?

macOS 14.2 or later on Apple silicon or Intel, and Windows 10 (build 2004 or later) or Windows 11, 64-bit. There is no phone, Linux or browser version.

Can I use it in an online assessment or a proctored test?

No. Helpwing is for live interviews. Don't use it in exams, online assessments, coding tests or proctored tests.

How much does it cost?

15 free minutes on first sign-in, then pay-once packs: ₹299 for 60 minutes, ₹1,199 for 300 or ₹2,999 for 1,000, GST included ($6, $24 or $60 outside India). No subscription. Details on the pricing page.
