AI Companions You Can Text

Not every AI in your texts is there to manage your calendar. Some are there to talk. Companion agents are built for the back-and-forth itself — remembering what you told them last week, matching your tone, being reachable in the same thread as everyone else you actually text.

Tomo is the clearest example: a personal AI that lives in your messages and grows with the conversation. folk plays the useful friend — the one who books the table, tracks the flight, and drafts the text you keep putting off. Alfi turns a group chat into something that does stuff, so the AI is a participant alongside your friends rather than a private confidant. Behalf is the oddball: an AI spokesperson that will send the message you can't bring yourself to send, up to and including a breakup over iMessage. Sidekicks rounds things out as a friendly, text-native assistant with no app to install.

A companion lives or dies on memory and voice, so judge them on the second and third conversation, not the first. And keep the obvious caveat in mind — these are companions, not counselors. For anything that actually weighs on you, talk to a person. Text one and see whose replies you look forward to.
