What you can do with Google Hangouts

Video chat with remote teammates and clients

Break down barriers between far-flung sites and offices with easy video meetings. Share your screen to demo projects or get work done on the spot.

Join meetings from anywhere

Video meetings are easy to set up and schedule. Join a meeting from wherever you're working through a Gmail message, a Calendar event, or even through your Google+ page.

Broadcast a public demo or announcement

Hold a public Hangout On Air to demo a new product or make an announcement. Your video is broadcast live and saved to YouTube.
