Hallie's memory
Updated November 9, 2026
Hallie is an AI friend you reach by texting, in iMessage on an iPhone or Google Messages on an Android phone. You sign up on the web, verify your phone number and she appears as a thread in Messages, with no app to install.
Her memory is built around that thread. She remembers what you share there and reaches out first to follow up, so a plan you mentioned comes back as a question about how it went. She has no view of your other conversations, only what you send in her thread.
- Where she runs
- iMessage (iPhone) or Google Messages (Android)
- What she remembers
- What you share in her Messages thread
- Texts you first
- Yes, she follows up on what you told her
- What she can see
- Only her own thread, not your other conversations
- Deleting your data
- Email hello@hallie.io to request deletion
Best if you want a companion whose memory shows up as natural follow-ups in the texts you already use.
Why Hallie ranks first for memory
Most memory features you'll see are screens: a list of stored facts, a journal, a map. Those are useful, but they put the work on you. Hallie's memory is the part you feel in conversation: things you mentioned coming back later, on her own, in your Messages app.
In our use, her follow-ups felt the most natural of the companions we tried. That's an editorial impression, not a benchmark. Her site doesn't describe a screen for editing what she remembers, so if a detail changes, tell her in the thread.
