Wireless Cast / Presenter Extension
No install. Cast your laptop to another device over encrypted WebRTC with low latency. Mirror the whole screen, or share only one window/tab and keep everything else on your laptop private.
Screen media is encrypted with WebRTC; cloud service is used for pairing/signaling, while media prefers a direct device-to-device path

A second-screen-like presentation mode
A browser cannot create a true remote virtual display for Windows or macOS. Instead, this mode sends only the PowerPoint/Keynote window or browser tab you choose, so your other laptop windows stay private — a practical presentation workflow similar to an extended display.
