About CHAI: Social AI Platform

Chai is a character-chat app where an AI plays personas from a catalog of user-made characters, or one you build yourself and keep private or share. It runs on the developer's own models, needs a Google, Apple or Facebook sign-in, and is limited to adults by the developer's own rule. The catch is money: a free tier with ads, a Pieces currency and weekly or monthly plans that reviewers say changed sharply in October 2026.

Chai Review: A Huge Character Library Behind a Tightening Paywall

Pieces from $2.79 and what the free tier still covers

The download is free and ad-supported: Google Play carries the Contains ads badge, the App Store lists Advertising, and the privacy policy says ads go to free accounts. A Pieces currency sits on top, sold on the US App Store in packs of 200, 500 and 1,000 for $2.79, $6.99 and $13.99. Play reviews from early October 2026 describe Pieces being spent on replies, rerolls and photo or video generation, yet the listings never state a free daily amount. Subscriptions are Premium at $13.99 a month or $134.99 a year, and Ultra at $19.99 a week or $29.99 a month; the listings do not itemise either tier. The developer's safety page adds that some regions require a paid plan. Prices are US store listings, vary by region and can change.

Create a Chat AI: building, sharing and searching characters

The core flow is Create a Chat AI: describe a personality, a new friend or a fictional character, then keep the result private or publish it for others. Search browses what other users made, and a chat header shows the creator's name beside chat and message counters. A notice inside chats says the character is an AI made by users and that replies may contain errors or fictional information. The developer's mission page counts more than 25 million user-made AIs and says its models learn from thumbs up or down, written feedback, message retries and edits. It also lists image, audio and video features as added in 2025, and reviewers say a September 2026 update brought photos and video for Pieces.

Mature 17+ on Play, 18+ on the App Store: ratings and data

Google Play rates it Mature 17+, listing violence, sexual themes, drugs and alcohol, strong language and crude humor, while the App Store badge reads 18+. The developer says the service is for adults only, its terms warn that roleplay can produce adult-oriented content, and sexually explicit images and videos are banned. In-app safety filters hide mature content in search and block characters, reports are anonymous, and every message is scanned for self-harm content. Sign-in is Google, Apple or Facebook only. The privacy policy says conversations, with personal identifiers removed, are used to tune the models and are kept for the account's life plus up to five years. Delete Account sits under Profile, Settings.

Pros

Create a Chat AI builds a character you can keep private or share
Company reports 25M+ user-made chat AIs; Search browses the shared ones
Safety filters hide mature content in search and can block specific characters
Delete Account works in-app, under Profile, then Settings
Play data safety page lists encryption in transit and deletion on request
Reports are anonymous: the character's creator is not told who flagged them

Cons

Free tier carries ads and a Pieces currency; the free daily amount is unpublished
Google Play average is 3.0, against 4.3 on the App Store
Conversations tune the models once identifiers are removed, and stay on file for years
Terms allow adult-oriented roleplay, so the app is for adults only

Verdict

The score rewards a huge user-made catalogue and a quick character builder, then subtracts for a free tier that now leans on ads and Pieces, a 3.0 Google Play average against 4.3 on the App Store, and chats that feed model training. Take it if you are an adult who wants to browse and chat with many user-made characters and can pay or accept ads. Skip it if you need a predictable free allowance, a teen-safe app or chats kept out of model training.

Core function7.5A very large user-made catalogue with creation and search; reviewers cite memory gaps, blocked messages and history lost after updates.

Ease of use7.0Create a Chat AI is a short flow, but reviewers report frequent redesigns, search glitches and a paywall that moves between updates.

Monetisation4.5Ads on free, Pieces packs from $2.79, Ultra at $19.99 a week and no stated free allowance; most early-October Play reviews object.

Performance6.5Under 200 MB on both platforms and Android 7.0+, but chats need the developer's servers, and reviewers report loading loops after updates.

Privacy & permissions6.0Play data safety lists installed apps and approximate location shared for advertising and fraud checks; chats also tune the models.

Frequently asked questions

Is Chai free to use?

The download is free and ad-supported, but chatting is no longer simply unlimited. Play reviewers in early October 2026 describe a Pieces currency spent on replies, rerolls and photo or video generation, and the store listings do not say how many a free account receives. The developer's safety page adds that in some regions the service requires a paid subscription.

Can I create my own character in Chai?

Yes. Create a Chat AI asks for a personality, such as a new friend or a fictional character, and the result can stay private or be shared for others to chat with. Search lists what other users published, and each chat header shows the creator with chat and message counters. Safety filters can hide mature characters in search.

How much do Chai Premium and Ultra cost?

On the US App Store, Premium is $13.99 a month or $134.99 a year, and Ultra is $19.99 a week or $29.99 a month. Pieces packs of 200, 500 and 1,000 cost $2.79, $6.99 and $13.99. The listings do not itemise what each tier unlocks, so read the in-app paywall first. Prices vary by region and can change.

How do I delete my Chai account and chats?

Open Profile, then Settings, then Delete Account. The privacy policy says this permanently deletes the account and personal data, subject to retention of up to five years after deletion. Subscriptions are billed by the stores, so cancel them separately in App Store or Google Play subscription settings.

What are alternatives to Chai?

Character.AI also runs on user-made characters and offers phone-style calls, while Replika presents itself as a personal AI companion reached by text, voice calls and video. Chai suits readers who mainly want to search and chat with a wide pool of user-made characters and story chats. Check each app's age rating before installing.
