AI friends you can text without downloading an app

The short answer

Hallie is an AI friend you text in iMessage or Google Messages, on iPhone or Android (new Android sign-ups need a US number for now), with no app to install and nothing to switch on inside another product. She is not the only AI that works in a messaging app you already have; this page covers six others. They differ from her in more than the channel: most are assistants or agents that do tasks, some work on only one kind of phone, and some are an extra feature of an app you set up first.

Hallie

Best for: people who want a friend, not an assistant, in the Messages app they already use, on iPhone or Android.

Where it wins: Her case on this page is the combination. Messages is where she lives, from the first message, not an add-on to an app. She is in iMessage on iPhone and on a Mac, and in Google Messages on Android; Khio is iPhone only, and Gemini in Google Messages is Android only. There is no app to install and nothing to switch on inside another product: you answer a few questions on the web about how you like to text, then you text her, and her thread sits next to your other conversations. She is a friend, not an agent: she doesn’t read your email or calendar, and what she does instead is keep track of the people, plans and events you mention, bring them up later and ask how it went. 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, and if you ask her to stop, she stops. She understands the photos, voice memos and links you send. 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.

Watch-outs: She is in iMessage and Google Messages only, so not on WhatsApp, Telegram or Discord, and her thread is one-on-one.

How you pay: A subscription. Depending on the offer, your first conversation is free or you start with a free trial. There’s no free plan. The price is shown before you pay, and you can cancel any time in your account.

Kindroid

Best for: people who want to design a character and then text it from Messages.

Where it wins: Kindroid is the one product here where the person in your Messages thread is a character you wrote: personality, backstory, key memories, avatar and voice. It works over iMessage or RCS on iPhone and RCS in Google Messages on Android, and once text messaging is enabled its docs say the Kin’s proactive text messages and selfies are pushed to your phone.

Watch-outs: It is not an app-free product. Texting is a setting inside Kindroid (Profile, then Preferences, then Text messaging) and is for subscribers only. Only one Kin can be reached by text at a time. Kindroid says SMS and MMS are not supported. Regenerating a reply works only in the app. Its docs also say that if you haven’t texted your Kindroid in a while, proactive messages stop being sent by text. There is no ongoing free tier since October 1, 2026.

How you pay: A subscription on a 1-month, 3-month or 1-year plan. Kindroid does not publish prices on its site; it says you see “the exact price for your country and platform at checkout.”

More detail: Hallie vs Kindroid.

Khio

Best for: iPhone users who want a texting buddy that also keeps them on schedule.

Where it wins: Khio describes itself as “the AI friend you text on iMessage: your new study buddy, gym partner, accountability coach and second brain.” It can text first with scheduled reminders, morning and evening check-ins, follow-ups and weekly recaps, and it can join an iMessage group chat and play GamePigeon games.

Watch-outs: Texting Khio needs iMessage on an iPhone. Its FAQ says there is no Khio app for Android and that Android users can use its web chat in a browser. Proactive check-ins are part of the Pro plan; the Free plan includes 5 reminders a month, and Khio’s pricing page describes its free chat as AI chat while you get set up. Khio calls itself a friend, an accountability partner and a personal assistant on different pages. Live voice calls are in its iPhone app.

How you pay: Free at $0 a month, or Pro at $14.50 a month billed monthly, or $109.99 billed yearly (Khio pricing page, khio.ai, checked November 11, 2026).

Poke

Best for: people who want an assistant that handles email, calendar and reminders over text.

Where it wins: Poke’s docs describe it as “your AI assistant that lives in Apple Messages, Telegram, WhatsApp, and RCS”, where you “chat naturally to manage your email, schedule meetings, set reminders, search the web, and more.” Its docs say it is “available in all regions worldwide”, and its homepage says it proactively keeps you in the loop.

Watch-outs: It is an assistant. Poke’s homepage gives it “a personality who keeps things as real as a friend”, but the product is built around your email, calendar and other connected tools. After the free allowance is used, Poke says the free plan switches to “a lighter mode”. It may text you from different numbers depending on the channel you choose. A February 2, 2026 release note said WhatsApp was temporarily unavailable except in Italy and Brazil, and Poke’s pages don’t state the current status, so check before you count on WhatsApp. Its privacy notice says data may be used to train its models unless you select Maximum Privacy.

How you pay: Free at $0 a month, Pro at $19 a month, or Ultra at $199 a month with pay-as-you-go usage on top (Poke pricing page and FAQ, poke.com, checked November 11, 2026).

ChatGPT dot

Best for: ChatGPT Pro users in the U.S. who want an agent that texts them about work it is doing.

Where it wins: A dot is, in OpenAI’s words, “an always-on agent that keeps work moving across your tools and projects.” You can reach it through iMessage or RCS on Android with text, photos and voice messages, and it reaches out with results or decisions that need you.

Watch-outs: This is not regular ChatGPT in your texts. Texting belongs to a dot, dots are not included in the Free, Go or Plus plans, and texting is “rolling out in beta to ChatGPT Pro users in the U.S.” You need ChatGPT to set it up: you open the dot’s profile in the ChatGPT mobile app, desktop app or a desktop browser, verify your phone number and save its contact card. Texting is one-to-one, and OpenAI says group chats, phone calls and FaceTime aren’t supported through texting. When the dot needs approval, it sends a link back into ChatGPT. OpenAI frames it around tasks, not company.

How you pay: ChatGPT Pro, from $100 a month, with tiers at $100, $200 or $500 a month (OpenAI, “Pricing”, ChatGPT Learn, checked November 11, 2026).

Gemini in Google Messages

Best for: Android users who want an assistant one tap away while they text.

Where it wins: Google says you can chat with Gemini in the Google Messages app “to draft messages, brainstorm ideas, plan events, or simply have a fun conversation”, and that it is available in over 165 countries.

Watch-outs: It needs an Android phone and is not available on iPhone. Google’s requirements include the latest Google Messages, a personal Google Account that you manage yourself, and RCS chats turned on, and Google says it is being released gradually. Gemini is, in Google’s words, an “AI assistant”. We found no Google page saying that Gemini starts conversations in Google Messages on its own.

How you pay: Google’s help page for Gemini in Google Messages states no plan requirement.

Meta AI in WhatsApp

Best for: people who already use WhatsApp and want quick answers without adding anything.

Where it wins: Meta AI is Meta’s AI assistant, available in WhatsApp, Instagram, Messenger and Facebook with no separate account beyond your Meta account. In WhatsApp you tap the Meta AI icon or start a new chat with it, and you can use it in existing group chats.

Watch-outs: It lives in WhatsApp, which is an app; it belongs on this page only if WhatsApp is already on your phone. It is not in iMessage or Google Messages. It is an assistant, and WhatsApp’s own help page reminds you that “Meta AI isn’t a human, even though it may chat and respond in ways that seem like a real person.” Meta says it is available only in limited countries and might not be available to you yet. Meta says it may use your prompts, the messages you share and your feedback to improve AI quality. On July 24, 2026 Meta announced daily briefings and recurring tasks in the Meta AI app and on meta.ai, with WhatsApp to follow; we found no Meta page confirming that they now arrive in WhatsApp. Meta has also started testing usage limits on some features.

How you pay: Meta describes Meta AI as “a free AI assistant built by Meta” and says it is “free to use for everyday use.” Meta says that people who hit a usage limit can buy a subscription to unlock more before the limit resets.

Questions

Is there an AI friend I can text without downloading an app?

Yes. Hallie is an AI friend in iMessage and Google Messages, on iPhone and Android (new Android sign-ups need a US number for now), with no app to install and nothing to set up in another app first. Khio is an AI friend you text over iMessage on an iPhone. Kindroid subscribers can text one of their characters from Messages after turning it on in Kindroid’s settings. Poke, a ChatGPT dot, Gemini in Google Messages and Meta AI in WhatsApp also work in a messaging app, but their makers describe them as assistants or agents.

Do I need to download anything to text Hallie?

No. You answer a few questions on hallie.io about how you like to text, and then you text her in iMessage or Google Messages. She texts from a US number, and new Android sign-ups need a US number for now.

What is the difference between an AI friend and an AI assistant in my texts?

An assistant does tasks: Poke manages email and meetings, and a ChatGPT dot reports on work it is doing. A friend talks with you, keeps track of what is going on in your life, and asks about it. AI friend vs AI assistant goes into the difference.

Can I text ChatGPT like a contact?

Only through a dot, and only on some accounts. OpenAI says texting is rolling out in beta to ChatGPT Pro users in the U.S., over iMessage or RCS on Android. You set it up from the dot’s profile in ChatGPT. Regular ChatGPT conversations happen in its app and on its website.

Does Gemini work in iMessage?

No. Google says Gemini in Google Messages requires an Android phone, and it is not available on iPhone.

Which of these text you first?

Hallie starts conversations after you’ve texted her; she never texts a number that hasn’t texted her first. Khio can text first with reminders and check-ins, and proactive check-ins are part of its Pro plan. Kindroid’s proactive messages are pushed to text for subscribers who have enabled it. Poke sends proactive updates, and a ChatGPT dot reaches out with results. We found no Google page saying Gemini starts conversations in Google Messages, and no Meta page confirming that Meta AI’s briefings arrive in WhatsApp. AI that texts you first has more.

How do I start with Hallie?

Go to hallie.io, answer a few questions about how you like to text, and then text her from your phone. She never texts a number that hasn’t texted her first. The price is shown before you pay.
