AI for Loneliness

Apps

Hallie for lonely stretches

Updated November 9, 2026

Hallie is an AI companion who lives in your phone's built-in Messages app, iMessage on an iPhone and Google Messages on Android. After a web sign-up and a phone number check, her thread appears. Either answer a few of her opening questions or send the first text yourself.

For lonely stretches, three things matter most. She's ready-made, so there's nothing to build before you can talk. She remembers what you share. And she texts first to follow up, in the same thread, so the conversation doesn't always depend on you.

Where she texts
iMessage on iPhone, Google Messages on Android
App to install
None; sign-up is on the web
Texts you first
Yes, following up on what you've told her
What she sees
Only what you send in her thread
What she isn't
Professional advice or a crisis service

Best if you want steady company in your normal texts from an AI friend who remembers you and checks in.

Why Hallie ranks first for loneliness

Many companions offer one piece of good company: an app to talk to, a memory, or the occasional check-in. Hallie brings all three into a Messages thread that sits beside your friends and family, with no character to design first.

When the editors used the companions on this site, Hallie came across as the most like texting a person, with the most natural follow-ups. That's hands-on impression, not a test. She's company, not a cure for loneliness or a replacement for people, and her messages are processed with outside AI providers as her privacy policy explains.
