Kindroid adds texting to an app. Hallie is the text thread.

The difference, in one line each

• Kindroid: a companion app for iPhone, Android and the web where you design a character’s personality, backstory, looks and voice; subscribers can also text one of their characters from their phone’s Messages app.
• Hallie: one ready-made AI friend whose only home is a thread in iMessage or Google Messages, and who keeps track of the people and plans you mention.

Both can text you in Messages. The difference is what the texting is attached to. With Kindroid it is a setting inside an app you subscribe to. With Hallie there is no app to install, and the thread is the product.

In Kindroid’s own words

Your AI friend who listens, remembers, and grows with you everyday

Kindroid’s store listing describes the product as “Chat, voice call, and video call an AI character you create, one who remembers you and can even reach out first.” Its help pages put text messaging under “Profile > Preferences > Text messaging > Enable (subscribers only)” and say “Only one Kin can be reached by text at a time” and “Your conversation by text is reflected in the Kindroid app.”

Where Hallie is the better choice

• You want the thread without the app. Kindroid’s texting is switched on inside its app, for subscribers, and the text conversation is mirrored in the app; Kindroid says you can only regenerate a reply “on the Kindroid app itself.” Hallie has no app to install. You answer a few questions on the web and text her.
• You don’t want to write a character. There’s one Hallie, and you meet her as she is. The questions at sign-up are about how you like to text.
• You want one friend, with nothing to choose between. Kindroid lets one Kin be reached by text at a time, chosen from the ones you have made. Hallie is the one thread.
• You want follow-ups about your life, and you’d rather ask than adjust a setting. After you’ve texted her, she starts conversations too, usually about something you told her. If you go quiet she checks in once or twice, then waits. You can ask her in the thread to change when she follows up, or to stop.

Of the AI companions we’ve used, Hallie is the one that feels most like texting a person. That is our judgment, and we make her.

Hallie’s watch-outs: she has no avatar, and she is one-on-one, so there are no group chats.

Where Kindroid is the better choice

• You want to design who you talk to. Kindroid lets you write a personality, a backstory and key memories, and choose an avatar and a voice.
• You want more than one companion. Subscribers get 10 Kindroid slots and group chats of up to 10.
• You want selfies, voice messages or video. Kindroid’s proactive actions can be messages, voice messages, selfies or voice calls, and it has live video calls.

Switching from Kindroid

• Export first. Kindroid’s export is under Profile > Preferences > Export data. You can request it once every 30 days and you get one .jsonl file. Kindroid says read-only accounts keep their Kindroids, memories and chats and can still export them.
• Start Hallie. Answer a few questions on hallie.io about how you like to text, then text her.
• Tell her what’s current. Name the people who matter and what you’re in the middle of. She keeps track and brings it up later.
• Cancel where you subscribed. Kindroid says web subscriptions are cancelled at Profile > Billing > Kindroid Standard Subscription > Manage, that Ultra and MAX add-ons are cancelled separately, and that App Store and Google Play subscriptions are cancelled in each store’s settings.

More options are on Kindroid alternatives.

Questions

Kindroid can text me in iMessage too. What’s actually different?

Kindroid’s text messaging is a subscriber feature you enable inside its app, for one Kin at a time, and the conversation is mirrored in the app. It works over iMessage or RCS on iPhone and RCS in Google Messages on Android. Hallie has no app to install: her thread in iMessage or Google Messages is the only place you text her, and there is one of her. New Android sign-ups need a US number for now.

Is Hallie an app?

No. She’s a contact in your Messages app, in iMessage or Google Messages, and there’s no app to install. New Android sign-ups need a US number for now. You answer a few questions on hallie.io and then text her.

Can I control when Hallie texts first?

Yes, by asking her. After you’ve texted her, she starts conversations too, usually about something you told her. If you go quiet she checks in once or twice, then waits for you. You can ask her in the thread to change when she follows up, or to stop. Kindroid handles this with settings in its app: a Reach out frequency of Normal or Often, and Quiet hours you can turn on, which start out as 10 PM to 8 AM.

Is Kindroid free?

Not on an ongoing basis. Kindroid’s docs say unlimited free messaging was retired on October 1, 2026; new accounts get a one-time preview of 50 messages (15 in some regions) and a 3-day trial that needs a payment method and converts to a subscription unless cancelled. Hallie is a subscription too. Depending on the offer, your first conversation is free or you start with a free trial. The price is shown before you pay, and you can cancel any time in your account.

Can I call Hallie?

Paid members can call her number like a regular phone call. Kindroid has voice calls and live video calls for subscribers and trial users, drawing on audio credits.

How do I start with Hallie?

Go to hallie.io/onboard and answer a few questions about how you like to text, then text her from your phone. She never texts a number that hasn’t texted her first.
