AUTO-DETECTION

It knows when you're sharing. You don't have to.

Curtainly detects screen sharing across Zoom, Meet, Teams, Slack, and Discord - then drops the curtain automatically. No manual toggles. No forgetting.

APP HIDING

Your private apps vanish. Instantly.

WhatsApp, Telegram, Tinder, Bumble, personal email - all hidden the moment your screen is shared. They come back exactly where they were when you're done.
