Video chats can be a great way to communicate, but it often leaves you feeling a little lazy in the process. How many of us are half-aware of our posturing while wearing PJs? If you’re looking to improve your conversation skills on video chats, look no further.

Part art project, part computing experiment, the US+ Google Hangout app from artists and programmers Lauren McCarthy and Kyle McDonald is an artificial intelligence facial recognition app designed to help you improve your video chat skills. Talking too much? The app will mute you. Looking too gloomy and depressed? The app will let you know you should smile a bit more. It’s a personal, real-time coach for all of your video chats if you don’t mind giving up your privacy to a machine analyzing your speech and body patterns.
