Why people look for apps like Chai
Chai (listed on the App Store as CHAI: Social AI Platform- Chat) is a character-chat app from Chai Research Corp. Its US listing, checked October 16, 2026, describes a large selection of characters with authentic voices, free talk, and tools to build and share AI characters. The company site (chai.ml) presents Chai as a consumer platform for AI characters and stories.
That library is Chai’s strength. It is also why people leave. Recent App Store reviews repeatedly mention a Pieces message system that limits free chats, ads interrupting conversation, subscriptions they call expensive, and chats that disappear. Those are user reports on the listing, not our measurements. Chai’s listing itself shows in-app purchases for Pieces packs and Premium or Ultra subscriptions.
Other reasons include wanting pictures of a companion they designed, wanting live voice calls rather than character voices alone, or wanting an app focused on one ongoing relationship instead of browsing thousands of bots. Some people are looking for unfiltered roleplay. We cover that honestly below, because Duple is not that app.

Not included: browser-only NSFW tools that top many “Chai alternatives” listicles (Janitor AI, Crushon, SpicyChat and similar). Those apps do not match what we could verify as a clear, current iOS App Store listing for this guide. This page covers only App Store apps we could verify on October 14–16, 2026.
Which alternative fits you
You want another character library
Character.AI is the closest product model to Chai: millions of user-made characters, creation tools, text and live voice calls. PolyBuzz is another large character marketplace with free conversations and paid memberships. If you mainly want to hop between bots, Character.AI or PolyBuzz are the natural next stops—not Duple. For a deeper Character.AI comparison, see Character.AI alternatives. For PolyBuzz specifically, see PolyBuzz alternatives.
You are tired of Pieces, ads and paywalls mid-chat
Chai’s listing still describes free talk, but recent App Store reviews often describe Pieces limits, ads after a few messages, and pressure to subscribe. Character.AI’s free plan also carries ads and slow mode for some users; PolyBuzz reviews commonly mention ads too. Among companion-style apps, Replika’s free use, Nomi’s free start and Duple’s Lite plan let you try before paying. Kindroid’s trial needs a payment method and renews unless you cancel. For a fuller price breakdown, see how much AI companion apps cost.
You want a companion that remembers you
Nomi lists short- and long-term memory plus Shared Notes. Kindroid lets you write a backstory and implant key memories. Replika says it remembers your people, plans and goals. Duple has long-term memory: it saves facts, preferences and moments from your chats so your companion remembers you across conversations, and you can reset or delete those memories. These are the developers’ claims, not our measurements. For how memory claims usually work, read how AI companion memory works.
You want pictures of your companion
Duple is built around a companion’s look: generated selfies, personalised pictures, outfit design, Live Selfies (short generated videos) and a saved image library. Nomi and Kindroid both list generated selfies, and Replika lists image generation. Character.AI, PolyBuzz and Chai lead with character chat and voices, not a personal image wardrobe.
You want voice calls
Replika lists voice and video calls, Kindroid lists real-time voice calls, and Character.AI lists live voice calls. Nomi lists voice messages. Chai and PolyBuzz describe character voices (and coin- or currency-based voice extras where listed). Duple’s App Store listing focuses on text chat and does not offer live voice calls.
Where Duple fits, and where it doesn’t
Duple is an iPhone app for creating your own companion, or a roster of them: you choose their background, appearance and style, chat by text, receive generated selfies and Live Selfies (short generated videos), make personalised pictures, design outfits and keep favourite images in one library. It is free to download with a Lite plan. Duple Plus costs $6.99 a week, $14.99 a month or $69 a year on the US App Store, and Dokens, Duple’s in-app currency, start at $1.99.
Age rating: the US App Store listed Duple as 16+ on October 16, 2026.
What Duple is not: it is not an unfiltered roleplay app, it does not offer a library of millions of user-made characters the way Chai, Character.AI or PolyBuzz do, and it has no live voice calls. It is iPhone only and needs iOS 26 or later. If you want unrestricted roleplay or a big character catalogue, another app will serve you better.
Before you switch
- Your Chai chats and characters will not move to another app. Do not assume any app can import them.
- Cancel any Chai Premium or Ultra subscription through the App Store if you no longer need it (Settings → Apple ID → Subscriptions).
- Check the age rating and privacy label of the new app on the App Store in your region.
- Read what the new app means by “memory” and whether you can view, reset or delete what it saves.
- Check whether a trial renews automatically, and at what price.

FAQ
What is the best Chai AI alternative on iPhone?
It depends on why you are leaving. If you want another huge character library, Character.AI or PolyBuzz are the closest matches. If you want one companion that remembers you, look at Replika, Nomi and Kindroid. If you want to design a companion’s look and make pictures together, try Duple. Duple publishes this guide.
Is Chai AI free?
Chai’s US App Store listing describes free talk and in-app purchases. Paid options checked October 16, 2026 include Premium Membership at $9.99, Premium Subscription (Monthly) at $13.99, Premium Subscription (Annual) at $134.99, Ultra Subscription (Weekly) at $19.99, Ultra Subscription (Monthly) at $29.99, and Pieces packs from $2.79. Recent App Store reviews commonly describe a Pieces message system and ads on free use.
Does Chai AI have memory?
Chai’s App Store listing emphasises character selection, voices and conversation. It does not headline long-term personal memory the way companion apps such as Replika, Nomi, Kindroid or Duple do. App Store reviews sometimes mention chat history disappearing. That is user feedback, not a measured test.
Is Duple an unfiltered Chai alternative?
No. Duple is not built for unfiltered or explicit roleplay, and it does not offer a catalogue of millions of user-made characters. It is a 16+ iPhone app for creating your own companions, chatting by text and making pictures and Live Selfies together. If unrestricted roleplay is what you want, Duple is not the right fit.
What age rating does Chai AI have?
On October 16, 2026, the US App Store listed CHAI: Social AI Platform- Chat as 18+. The same day, Duple was listed as 16+. Character.AI, PolyBuzz, Replika, Nomi and Kindroid were listed as 18+. Ratings can change, so check the listing in your region.
Did you test these apps hands-on?
No. This is a feature-by-feature comparison based on official App Store listings and developer help pages, checked October 16, 2026 for Chai and Duple, and October 14–16, 2026 for the other apps on this page. We did not publish scored test results.
