If you want to send friends custom emoji using Gboard, you can either tap into your Bitmoji sticker collection... or use the keyboard's latest feature. Google has launched "Mini" stickers for iOS and Android, which use machine learning to craft personalized emoji from your photo. More precisely, the feature uses a combination of machine learning, neural networks and artist illustrations to conjure up the best representation of you, taking into account various characteristics like your skin tone, hair color and style, eye color, face shape and facial hair. Just access Mini from within Gboard and start the creation process by taking a selfie. It will then automatically create your avatar and generate packs of stickers you can use.
