Chai AI alternative that does not train on your chats

Chai is a big, genuinely popular app: 25 million user-made characters, mobile first, free to start, and by its own company's account around $70 million a year in revenue by 2026. If you want a huge library of community characters on your phone, Chai delivers that better than we do, and it is worth saying so before anything else.

Short answer

Chai is a mobile-first AI chat app with roughly 25 million community-made characters and a free tier. The tradeoff is stated in its own privacy notice: Chai uses personal data derived from your in-app conversations to fine tune the AI models its chatbots run on, and says data will not be kept longer than the life of your account plus five years after deletion. Depravity is a Chai AI alternative for US adults 18 and over who want candid, uncensored conversation without that tradeoff: encrypted chats that are never sold, never shared, and never used to train advertising, one consistent set of limits instead of per-character roulette, and firm lines against minors, non-consent, and anything illegal. Paid only, from $15 a month.

Last updated July 2026

The reason people look for a Chai AI alternative is usually one of two things. The first is that what happens to your conversations is not ambiguous: Chai's own privacy notice says it uses personal data derived from your in-app chats to fine tune the models those chatbots run on, and that data can be kept for up to five years after you delete your account. The second is consistency, because Chai is a user-generated platform and what a given character will and will not do depends on who made it and how the current moderation layer is feeling. Depravity is built the other way: your chats are never used to train advertising, never sold, never shared, and the limits are written by us and stated plainly.

What makes it feel honest

Chai AI alternative, the way it should feel

Your chats are not training data

Never sold, never shared, never used to train advertising. Encrypted, and yours to export or delete anytime.

Consistent, not crowdsourced

One set of limits written by us, the same in every conversation, instead of per-character behavior that varies by author.

Hard lines that hold

Candid on adult topics, immovable on minors, non-consent, and anything illegal. Written down, not improvised.

Honest comparison

Chai compared with Depravity, from primary sources where they exist

	Chai	Depravity
Trains on your conversations	Yes. Its privacy notice says it uses personal data derived from your in-app conversations to "enhance and fine tune" the models its chatbots run on, with identifiers removed first.	Your chats are never sold, never shared, and never used to train advertising. Encrypted in transit and at rest.
Data retention after deletion	Stated as no longer than necessary, and "not exceeding, in any case, the duration of the account and five (5) years following its deletion."	Export or delete any conversation yourself, from settings, whenever you want.
Character library	Around 25 million community-made characters. Far more variety than we offer, and a real strength.	A small set of crafted personas rather than a marketplace. Fewer choices, more consistent behavior.
Content limits	We could not verify a clear, current NSFW policy from Chai's own pages. Its FAQ answers the question by noting it is a user-generated platform. Third-party reports conflict, so we will not state it as fact.	Candid adult conversation is permitted by default. Minors, non-consent, and illegal content never are, and no persona or prompt changes that.
Free tier	Yes, free to start. We do not have one, and that is a genuine advantage for Chai.	No free tier. Paid only, from $15 a month, or $12 a month billed yearly.
Price	Chai's company site publishes no pricing. Reported figures vary widely between sources and store listings, so treat any number you read as unverified and check in the app.	Published on the site: $15, $29, or $59 a month, cheaper billed yearly. No surprises.

Chai's training and retention rows are quoted from its own privacy notice, reached from privacy.chai-research.com, checked July 2026. Where Chai does not publish something, notably its pricing and a plain statement of its adult-content policy, we say we could not verify it rather than repeating a number from a review site. Credit where it is due: Chai's character library and free tier are real advantages, and it is a much larger product than ours.

Does Chai AI train on your conversations?

Yes, and you do not have to take a competitor's word for it. Chai's privacy notice states that it uses personal data derived from your in-app conversations with chatbots to enhance and fine tune the artificial intelligence models those chatbots operate on. It says personal identifiers are removed before that use. So the conversations themselves feed the product; the claim is that they are stripped of the things that point back to you.

Whether that is acceptable is a personal call, and plenty of people will shrug at it. But it is worth knowing before you type something you would not say out loud, because the same notice sets retention at up to five years past account deletion. If your reaction to reading that is to look for something else, that is the entire reason this page exists.

Chai vs Depravity: which should you use?

Use Chai if you want breadth and a free way in. Twenty-five million community characters is a genuinely huge catalog, the app is polished on mobile, and you can try it without paying. If what you want is to browse and sample dozens of personalities, we do not compete with that and we are not going to pretend to.

Use Depravity if the conversation matters more than the catalog. You get a small set of personas that behave consistently, one written set of limits instead of whatever the character's author configured, and a specific data promise: encrypted, never sold, never shared, never used to train advertising, yours to export or delete. It is paid only, from $15 a month, because the business model is subscriptions rather than scale.

The problem with crowdsourced characters

A user-generated platform means the experience is only as consistent as its authors. One character will hold a scene, the next breaks it. One respects the setup you wrote, another ignores it by the fourth message. And when moderation changes, it lands unevenly across millions of bots that nobody at the company wrote or reviewed. That variance is the price of a huge library, and for casual browsing it is a fair price.

It is a bad price when you actually want to talk. If you are having a real conversation, or building a story across sessions, you want the thing you are talking to to behave the same way tomorrow as it did today. That is why we ship a handful of crafted personas rather than a marketplace. Fewer options, but the one you pick works the same every time.

What "uncensored" means here, and what it does not

Uncensored on Depravity means free of the corporate filters that refuse ordinary adult subject matter, moralize mid-sentence, or end a conversation because it drifted somewhere a brand safety team dislikes. You can talk about sex, grief, anger, money, addiction, or anything else adults actually talk about, without a wall dropping in.

It does not mean free of law or ethics. Nothing involving minors, nothing involving non-consent, and nothing illegal is ever permitted, on any persona, under any prompt or setting. Those lines are published, they are enforced with automated and human review, and they do not move. A company willing to state its limits in writing is usually the one being straight with you about the rest.

Switching from Chai

There is no export or import between the two, so switching means starting a conversation rather than migrating one. In practice that takes a few minutes: pick a persona, tell it who you are and what you want from it, and it carries that forward across sessions instead of resetting.

Before you leave, it is worth going into Chai and deleting your account rather than just uninstalling the app, since the retention clock in its notice runs from deletion. And if you want to compare more broadly first, our honest look at the field covers the same ground for the other major apps, including the ones whose privacy policies we could not verify at all.

Questions about your chai ai alternative

It depends what pulled you away. If you want a bigger character library, nothing beats Chai on volume. If you left because your conversations are used to fine tune its models, Depravity is built for that objection: encrypted chats, never sold, never shared, never used to train advertising, for US adults 18 and over from $15 a month.

Yes. Chai's privacy notice states it uses personal data derived from your in-app conversations with chatbots to enhance and fine tune the AI models those chatbots run on, after removing personal identifiers. The same notice caps retention at the life of the account plus five years after deletion.

It is free to start, which is a real advantage over us. Chai does not publish pricing on its company site, and reported paid-tier figures differ between review sites and store listings, so check the app rather than trusting a number you read elsewhere. Depravity is paid only, from $15 a month.

Yes, for adults. Depravity permits candid adult conversation by default rather than deflecting or lecturing. No filter means free of corporate content gates, not free of law: nothing involving minors, non-consent, or anything illegal is ever allowed, regardless of persona or prompt.

It is a real product from a real company, not a scam. The safety question worth asking is about data, not malware: its own notice confirms conversations fine tune its models and can persist up to five years past deletion. Decide with that in mind, and avoid typing anything you would not want retained.

They are encrypted in transit and at rest, never sold, never shared with data brokers or marketers, and never used to train advertising. You can export or delete any conversation from settings. Automated and human review exists only to enforce the hard lines on prohibited content.
