I built a screen share with a blocklist — Slack, ChatGPT, and email stay private

Every screen share starts with the same ritual:

Close Slack. Hide ChatGPT. Move email away. Clean the desktop. Turn off notifications. Then hope nothing private appears during the call.

I m building Unshown, a macOS app that gives screen sharing something it should have had years ago: an exclusion list.

Choose the apps you want to keep private, start a Protected Share, and select Unshown as the sharing source in Zoom, Google Meet, or another meeting platform.

Unshown - Keep selected Mac apps out of your screen share

Unshown creates a protected share window that excludes selected apps from live demos, support calls, and recordings. Unshown creates a separate macOS share window that excludes the apps you choose before frames reach your meeting or recorder. Keep Slack, Mail, Messages, Terminal, and internal tools available locally without putting them in the shared output.
