Kettle is a helper in your family's group chat. There's no app and nothing to set up: text it on its own, or start a group message with "Kettle." It remembers the details you tell it, plans dinners around your week, builds a grocery cart for you to review and check out, and sends group or private reminders plus a short morning brief. Getting started: text hi, each person texts once so it knows who's who, then add Kettle to the group. 7 days free, then $19 a month for the whole family.

bonds is the messaging app for the next generation. Every friends' chat gets an AI friend with superpowers. Not an assistant: it gets your inside jokes, keeps the fun going, helps you pull things off together. A little unhinged 💀 "A week without TikTok?" It creates a challenge app with streaks, inside the chat. No downloads. Games, videos, stickers, too. It remembers what matters to each of you, notices when someone's struggling, gets grumpy if you ghost it. You care for it, it cares for you.
