Looking for an App Like Zeta? Text Roleplay, Then a Character You Can Call

Prelulu is a Zeta AI alternative for readers who love character roleplay and also want to hear and see the character. Zeta, by Scatter Lab, centers on text roleplay with millions of user-made characters, memory and illustrated scenes. Prelulu pairs text chat with live voice calls and, for supported characters, live avatar video calls. Free text has a daily allowance; calls use credits. On iPhone, Prelulu is on the App Store and also runs in Safari.

Definition

Does Zeta have voice or video calls?

Zeta's official notice of May 12, 2026 ended character voice playback on June 12, 2026, and we found no call or video-call feature in the official notices, store listings or help pages we reviewed on September 27, 2026. Zeta does offer Snapshot illustrations and, since September 23, 2026, Visual Novel Mode, where each scene changes the character's expression and background. This is a documentation comparison published by Prelulu, not a hands-on benchmark.

Why it works

Choosing between Zeta and Prelulu is about the kind of scene you want. Zeta is built for reading and writing a story with a huge community cast; Prelulu is built for the moment you want the character to answer out loud, and to see them do it.

Keep the roleplay, add a voice

Prelulu's text chat is roleplay too. When you want to, call the same character by voice and keep the story going, then return to text.

See the character answer

On supported characters, a live avatar video call shows the character answering you face to face, with expressions and a voice that carry emotion.

A different kind of catalog

Zeta's strength is scale: its store listing describes millions of user-made characters and a creator that takes about a minute. On Prelulu you meet written characters with real depth, or create your own.

Different ways to pay

Zeta's basic chat is free, its premium models cost Pieces per turn, and Zeta Pass is a monthly subscription. On Prelulu, text has a daily free allowance, paid plans remove the limit, and voice and video use credits.

FAQ

Questions, answered

Not when we checked. As of November 7, 2026, Zeta's iPhone app was not available on the App Store in the US, UK, Canada and Australia (Apple lookup returned no app; the App Store page returned 404). Its Google Play app and website remain available. The same day, Apple's lookup returned no Zeta app in Korea, Japan, Taiwan or Germany either, and its Korean and Japanese App Store pages returned 404. Zeta posted a notice on November 7, 2026 but gave no reason: it says the app is unavailable for download on the Apple App Store and in-app purchases are temporarily unavailable. Zeta's notice says that if the app is already installed you can keep using it as usual, and that if you deleted it but downloaded it before, you can reinstall it from App Store > your profile icon > Apps & Purchase History > Your Apps, by searching "zeta". If you never downloaded it or cannot reinstall it, the notice points you to Zeta on the web at zeta-ai.io, which you can open in Safari; Zeta's website shows its own usage limit for the web version. Android users can still install it from Google Play, where it was last updated November 3, 2026. The same notice says App Store in-app purchases and subscription renewals are unavailable, subscriptions already bought stay available for the rest of the current period, and payments work normally on the web; a subscription bought through Apple is managed in iPhone Settings > [your name] > Subscriptions. Zeta says it is working to restore App Store access and will announce it in an official notice or on its social channels. If you're new on iPhone, or want an app you can install today, try Prelulu: its iPhone app, "AI Video Call & Chat: Prelulu", is on the App Store (checked November 7, 2026). Text a character the way you would on Zeta, then call them by voice, or on supported characters by avatar video. Prelulu also works in Safari at prelulu.ai, so you can start a chat before you install anything.

On the web and on Android, yes. The Korea Herald reported on January 15, 2026 that Zeta, made by Seoul-based Scatter Lab, was entering the US market through a closed beta, and Zeta's September 29, 2026 notice says buying Pieces on its website was open only in the United States. Apple's US App Store lookup listed "zeta: AI Chat, Story, Play" on October 27, 2026, but returned no app on November 7, 2026. Prelulu is on the US App Store and Google Play, and works in any browser at prelulu.ai.

Prelulu is one option: you can text a fictional character the way you would on Zeta, then switch to a live voice call, or an avatar video call on supported characters. Try a short call first to see whether the voice and pacing suit you.

Zeta's own documents, read October 22, 2026, say the app was rated 13+ on the US App Store (its listing there was gone by November 7, 2026), trains its AI on conversations with an opt-out that only covers future training, and may share identifiers with advertising partners; this is what they say, not our verdict. The app comes from Scatter Lab, Inc., and Zeta's privacy policy says users between 13 and 18 need a parent or legal guardian to review and agree to its terms on their behalf. The policy says Zeta uses conversation data to train, fine-tune and improve its AI models; you can ask to opt out, but that covers new training going forward, and Zeta is not required to retrain or delete models already trained. It also says Zeta may share identifiers and usage data with advertising partners for targeted advertising, and that it does not sell personal information for monetary consideration. For background, The Register reported in April 2021 that South Korea's Personal Information Protection Commission ordered Scatter Lab to pay 103.3 million won in penalties for using conversations from its earlier apps to build the Lee Luda chatbot without proper user permission.

Zeta's support FAQ, read October 22, 2026, says that unless you publish your gameplay yourself, it is not shared with third parties, including character creators, and that its operations team does not individually view your conversations. The same answer says AI-based monitoring (filtering) is applied as a mandatory measure, solely to confirm compliance with its usage policy and terms. Zeta's privacy policy adds that personal information is shared with vendors working on its behalf, including cloud infrastructure, AI model providers, customer support and data labeling.

Zeta's terms say you can close your account at any time through the service, and its privacy policy says you can delete your account information from your account profile page (both read October 22, 2026). After deletion, Zeta says it deletes or de-identifies your personal information, except records the law requires it to keep and information needed for pending disputes, legal matters or enforcing its terms. It also says conversation data already used to train its AI models may not be fully removable from those models, and content you made public may stay available to other users. On Prelulu, you can close your account at any time in Settings; closing ends access but keeps your existing chats and memories stored; to have your personal data erased, email privacy@prelulu.ai.

Not as of September 27, 2026. Zeta's official notice of May 12, 2026 stopped new voice purchases and ended character voice playback on June 12, 2026, describing it as a low-use feature that was hard to maintain.

Zeta opened it to everyone on September 23, 2026. Its official notice describes scenes in which the character's expression and background change, with AI helping generate character and background images. It is a visual storytelling mode, not a live call.

Zeta lists memory as a feature, and its official notice of January 12, 2026 describes up to 4x longer memory for the premium koji model, which costs Pieces per turn. We did not measure memory quality side by side, so test it yourself: share an invented detail with a character on each app, come back in a later session, and see which one recalls it. On Prelulu, your character remembers what matters in your chats and picks up every call where the last one left off.

Zeta describes its basic chat as free. Its premium models cost Pieces per turn (5 for koji and 10 for luca from August 7, 2026, per its official X account). Its October 29, 2026 announcement says Pass subscriptions and 1-day passes are available on the web for around 20% less than in-app prices, with web payments currently limited to the United States. Pieces Auto Top-Up is separate: if you enable it, Zeta automatically buys your chosen quantity when your balance falls below the threshold you set. You can enable or disable it only on Zeta's website. These are paid purchases, not free Pieces. Zeta's November 7, 2026 notice says in-app purchases and subscription renewals through the App Store are unavailable, and that payments work normally on the web.

Your Zeta chat history cannot come over, because the two services are not connected. The character can: on the web, import it by pasting its description or dropping in a screenshot of its profile, then review the draft before you save it. You can also create your own in Prelulu's creator; respect other creators' work either way.

Yes. Prelulu is free: texting is free every day, with no card needed, and paid plans remove the daily limit. Signup welcome credits can fund a short call, and daily check-in adds call credits.

No. It compares what each product officially documents, with source-specific review dates below. The web Pass and Auto Top-Up announcement was checked November 2, 2026, and the App Store check ran November 7, 2026; other feature checks retain their earlier dates. We did not measure speed, memory quality or Korean and Japanese fluency side by side.

We cannot see Zeta's servers, so check its official notices at support.zeta-ai.io first. The most recent outage notice there, dated October 12, 2026, reports that access was disrupted from about 8:28 to 9:11 PM Korea time and has been restored (read October 24, 2026). For a problem with your own account, Zeta's listings give contact@zeta-ai.io. Prelulu is a separate service: if you want to keep a story going in the meantime, it runs in a browser at prelulu.ai and on iPhone and Android.

Yes. Zeta's website, zeta-ai.io, shows its character catalog in a browser, and its September 29, 2026 notice says you can sign in there and buy Pieces from a PC or mobile browser, at about 20% less than in the app; web payments were available only in the United States at the time. For a new iPhone user the website is the way in: Zeta's iPhone app was not on the App Store when we checked on November 7, 2026. Zeta's notice that day points anyone who never downloaded the app, or cannot reinstall it, to the website, and says payments work normally on the web while App Store in-app purchases are unavailable. Prelulu also works in a browser at prelulu.ai, chat and calls included, and has apps for iPhone and Android.

No. Zeta's September 3, 2026 notice describes LIVE Chat as a text panel of simulated viewer messages and donations that appears during broadcast scenes in a story, in plots whose creator turned it on. It is a storytelling effect, not a call with the character. On Prelulu, a call is live: the character answers you by voice, and supported characters appear on an avatar video call.
