Question: Do you know of a service that allows me to create and share custom sticker packs with friends and family?

For making and sharing custom sticker packs with friends and family, Mirror is a great choice. It combines sophisticated facial recognition technology with a lot of customization options to turn a selfie into thousands of personalized stickers that you can use in any messaging app. It works with 20+ major languages, so it's a good option for multilingual communications. The free version offers some customization, but the premium version offers more.

Another option is more.graphics, a collection of AI-powered tools to create unique graphics, patterns and other designs. The Face AI Sticker Generator lets you turn selfies into custom stickers that you can export to popular messaging apps. It also adds new options to the generator daily and has a community forum for help and discussion.

If you want a more full-featured service, Bobble AI also lets you create custom bobblehead stickers and GIFs from selfies. It supports more than 100 languages and has a transliteration service to convert Latin script to regional languages, so it's a good option for multilingual communications. The company also offers white-label custom keyboard options and brand marketing tools, so it's more useful than just a sticker generator.
