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

APP HIDING
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.

SMART BLUR
Curtainly blurs browser windows and messaging apps. Need to show a tab? Reveal it with one click. Switch tabs and the blur returns.

Free forever. Pro for life.
