2
Send the link
Drop the link in any chat — Slack, WhatsApp, email
3
They open, they watch
Any browser, any device — the link is your screen

Two ways to use it, zero installs

Zero install
Never making the other person download anything is our first product principle. Sending and watching both live in the browser.
End-to-end encrypted
Video travels directly between devices, encrypted. It never touches our servers — even we can't see it.
Low latency
Direct peer-to-peer transport — low enough to follow your cursor in real time.
Cross-platform
Desktop to phone, phone to tablet — anywhere with a browser works.
