Flintalk uses macOS content protection, so the overlay is excluded from screen capture. Google Meet and Microsoft Teams respect it automatically. Zoom needs one setting, documented below, and the built-in Safety Test lets you verify all of it before the call.
Share your entire desktop on Google Meet or Microsoft Teams and the overlay is left out of the capture. Nothing to configure. We test this against the real apps before every release.
Zoom's full-desktop capture works differently. Turn on Advanced capture with window filtering in Zoom (steps below), or simply share a single window instead of the whole desktop, and the overlay stays out of the share.
Press ⌘⇧T in the app to run the Safety Test. It takes a real screenshot, the same way a screen share captures your display, and shows you exactly what others would see. Flintalk also warns you when it notices Zoom running.
After that, full-desktop shares in Zoom exclude the overlay just like Meet and Teams do. If you are on a machine where you cannot change Zoom's settings, share a single window instead of the desktop; the overlay is its own window and is never part of another window's share. Either way, run the Safety Test once before a call that matters.
Honest limits: content protection is a macOS capability, not magic. A phone pointed at your screen or a capture card sees everything. Within screen-share software, this is tested against the real Zoom, Meet, and Teams apps before every release. Last verified August 24, 2026.
No bot in the meeting, nothing on the shared screen. The copilot sits next to you, not in the room.
