Cluely's stealth is a browser overlay. That works when the user is screen-sharing a single browser tab — the overlay sits above the captured content and isn't included in the share. But on full-screen share or OS-level screen recording, the overlay is visible.
WispherFlow goes a layer lower. On Windows we call SetWindowDisplayAffinity(hwnd, WDA_EXCLUDEFROMCAPTURE) and on macOS we set NSWindowSharingNone on the window. The operating system itself excludes our window from every capture buffer — screen recording, Zoom share, OBS, Loom. There is no workaround at the application layer because the protection happens before the bits ever leave the GPU.
Cluely's a simpler product. If you only ever screen-share a single browser tab (not full-screen), and you don't need resume-grounded answers or multi-model switching, the browser overlay is faster to set up — no installer.
If you're doing FAANG-style interviews, multi-tech-stack consulting work, or anything where the interviewer might full-screen share — WispherFlow's OS-level protection is the safer call.
