Each of these Characters leads a Story that opens straight into a scene, with the tension Zeta's most played plots are known for already in the room. Open the Story, choose Enter, type the name you want to be called and write your first line.

• Zeno Stokeleigh in Mafia Husband: Is He Like the Rumors?: your sister was promised to the feared mafia boss, they sent you instead, and his arms are already around you.
• Oscar Kessler in The Yandere Husband: you wake up in a rich man's bedroom, he is gentle with your hair, and he has decided you will fall in love with him.
• Dorian Ashcroft in The Villainess's Easy Life: you wake up as the doomed villainess of a romance-fantasy novel and decide the tragic script is not for you.
• Ivern in Mine From the Beginning: your childhood friend was raised to keep you by his side, and he calls the engagement he just announced nothing new.

What is Zeta AI?

Zeta (written in lowercase as zeta, and searched as "Zeta AI") is an AI roleplay and character chat app from Scatter Lab, Inc., a Seoul company. You pick a character or a plot, write your side one turn at a time, and the AI plays everyone else; you can also build your own characters. Zeta launched in Korea on 1 April 2024, came to Japan that May and opened its apps worldwide on 17 May 2026. By September 2026 it had 13 million sign-ups across Korea, Japan and the US. Its website's menu runs Home, Ranking, Discover, Create, Chat and My Page, and the plots on its front page lean on romance, yandere and BL tags.

Is the Zeta app off the App Store?

Yes. As of 13 November 2026, Zeta's iPhone app has no listing on the App Store. Apple's own lookup for the app (id 1619030760) returned no result in eleven storefronts we checked, from the US and UK to Japan, Korea and Brazil; the listing page returns "not found"; and App Store searches for "zeta ai" in the US and "제타" in Korea show other apps. RoboRhythms first reported the listing gone on 7 November 2026.

What still works on 13 November 2026:

Your Zeta chats belong to your account, not to the app, so logging in on the website with the method you used in the app opens the same account and history.

How to use Zeta AI online on a PC

Zeta's website is the official way to use Zeta on a computer. It runs in any desktop browser with nothing to install.

1. Go to zeta-ai.io in Chrome, Edge, Safari or Firefox.
2. Browse Ranking or Discover, or search for a character, then open it and start the chat.
3. Write your first message; the character answers in the same window.
4. Tap Log In at the top right when you want Zeta to keep your chats and your Pieces, its in-app currency.

The website has the same characters and your same chat history once you log in with the account you use on your phone. On 19 October 2026 Zeta's Japanese website also let visitors start a chat before logging in; log in before a long chat so it is saved to your account.

Zeta AI login

To log in to Zeta online, open zeta-ai.io and tap Log In at the top right. The English Login / Sign up sheet offers Continue with Google and Continue with Apple; the Korean site adds Kakao and the Japanese site adds LINE.

• Choose the method you signed up with. Zeta's support site says the login method linked to an account can't be changed later, and signing in another way starts a new, empty account. If your chats seem to have vanished, log out and sign in with your original method.
• iPhone players signed up with Apple. Continue with Apple works on the website too, including in Safari on the iPhone.
• Zeta is down? Its support site posts outage notices under What's New; on 12 October 2026 the service was down from about 8:28 to 9:11 p.m. Korea time.

Can't get in at all? Teasa needs no login for your first 20 turns: start an AI chat roleplay in your browser now.

The Zeta web version: limits and what differs from the app

Zeta's help center says the web version has a daily chat limit that resets every day; at the limit a "That's all for today" message appears. Zeta Pass removes it. With the iPhone app off the App Store, the website and its limit are where iPhone players chat for now.

Zeta's chats are free, with ads, and its premium chat models cost Pieces per turn. Zeta Pass cost $2.79 for a day or $14.99 a month on the US App Store when we checked on 21 October 2026, adding ad-free chat, 200 Pieces a month (not with the day pass), faster replies and unlimited private characters; Zeta's FAQ adds that it "does not improve the performance of the AI model itself."

Can you download Zeta for PC?

No. Zeta offers no Windows or Mac app; the website is the official way to use it on a computer. Two workarounds put Zeta in its own window or run the phone app:

• Install the website as an app. In Chrome, open zeta-ai.io, then the ⋮ menu, Cast, save and share, Install page as app. Edge has the same option under Apps. Zeta then opens in its own window from the taskbar or Dock.
• Run the Android app in an emulator. Android emulators such as BlueStacks install Google Play apps on Windows or a Mac. That means installing the emulator first, and it is the emulator's service, not Zeta's.

Teasa: AI roleplay that starts in your browser

Teasa is built for the browser from the start. Open teasa.ai on a PC, Mac, Chromebook or iPhone and you're one tap from playing: pick a Story, read its opening scene and write what you say or do. Guests play their first 20 turns without an account, and a free account keeps going with Hojicha, free and unlimited. When Teasa asks, create a free account with Google or email and the same Story carries on from where you stopped, on every device you sign in to. Prefer an app? Teasa is on the App Store for iPhone and iPad, on Google Play for Android, on the Microsoft Store for Windows and inside Telegram.

What changes compared with Zeta is where the conversation starts. A Teasa Story opens with an authored scene, a role for you and a cast with something at stake, and it can carry quests with visible objectives and relationship milestones that record the moments you earn with a Character in History. You type dialogue or actions in your own words, regenerate a reply, branch the conversation and come back to saved chats later.

Outside the Story, any Character is a direct message away. DMs need a free account and are free and unlimited, so you can talk about what just happened in the Story or about your own day. A Memory panel shows the facts collected about you and lets you forget any of them. Creator Studio is there when you want to build your own Characters, with AI-generated portraits, and your own Stories, and the interactive AI story app page shows how a Story plays out, like an AI story generator you play from the inside.

Teasa has four chat styles: Hojicha, free and unlimited; Matcha, with a 50-reply welcome and then 3 free replies a day in most countries; Earl Grey, with Teasa Pass; and Oolong, with Teasa Pass Pro. Teasa Pass adds live web lookup in DMs, ad-free play and priority replies. See Teasa's pricing for your region.

Where to start if you came from Zeta

• Yandere & Obsessive Love: devotion with an edge, the tag Zeta's front page leads with, told as a Story you play.
• Mafia & Gangster: dangerous men, arranged vows and loyalties you can test.
• Villainess: wake up inside a romance-fantasy novel and rewrite your ending.
• Contract & Arranged Marriage: a marriage on paper and a slow turn toward something real.
• Regret & Win-Back: the one who let you go, finally sorry, and you decide what happens next.

Play your first Story in the browser

1. Open teasa.ai in any browser on your PC, Mac, Chromebook or phone. There's nothing to install.
2. Pick a Story from one of the collections above, or browse Teasa Characters and start with a face you like.
3. Read the opening scene and write your first line of dialogue or action. The cast responds to what you actually do.
4. Play your first 20 turns as a guest. When Teasa asks, create a free account with Google or email and your Story continues from the same moment.
5. Open Characters, pick someone and tap Message to start a direct conversation, free and unlimited on your account.

Came from another AI chat app?

Teasa answers the same questions for every big AI character chat app: where it runs in a browser, how to log in, what it costs and where to chat free right now.

• Character AI online: c.ai on PC, its login and what the Chapter 11 sale means for your chats.
• Talkie online: Talkie on PC and with no sign-in at talkie-ai.com, now that now.gg no longer streams it.
• PolyBuzz AI online: PolyBuzz on PC and in the browser after its own App Store exit.
• Chai AI online and where Chai players keep chatting: Chai on the web and Android since its iPhone app left the App Store.
• Janitor AI online: JanitorAI in any browser and its free JLLM model.

Not sure which one fits? The best AI roleplay apps puts Teasa, Zeta, Character.AI, Talkie, PolyBuzz and more side by side, and AI chat with no sign-up compares what you can do without an account.
