Enormous, quick and forgetful, with a privacy and billing record we cannot recommend. Chai has more bots than almost anyone and answers fast. It also loses the plot after 20 to 40 messages, trains on your chats without end-to-end encryption, has reshaped its free tier four times in 2026, and draws more surprise-charge complaints than any app in our companion guide.

What Chai is and who runs it
Chai is a mobile app for chatting with user-made AI characters, from fantasy adventurers to fictional partners to the occasional bored-sounding pirate. Anyone can build a bot and publish it to the community. The company behind it, Chai Research Corp., was founded in 2021 by William Beauchamp, a former quantitative trader, after a prototype built in Cambridge, England; it moved to Palo Alto in 2022. GPU cloud company CoreWeave is among its investors.
The scale is real. Chai's own website, checked on October 7, 2026, claims $100 million in annual recurring revenue as of July 2026, more than 10 million active users and over $55 million raised, and says it serves its models from 5,000 GPUs. Other reporting puts the team at around 15 people. All of those are company figures, not audited ones, and we treat them that way. But a $100 million run rate from a staff that small tells you what the business is optimised for: lots of users, lots of messages and conversion to paid, with very little headcount left over for support or safety.
Chai's pitch has always been that it is the looser alternative to Character.AI, with fewer refusals and more freedom for bot creators. In 2026 that pitch has worn thin, for reasons we come to below.
Where the evidence in this review comes from
We read the two store listings on October 7, 2026, including the in-app purchase prices and Google's data-safety label, and Chai's own site. For pricing, memory and tier comparisons we relied on RoboRhythms, which published several hands-on Chai pieces between June and September 2026, including a two-week Ultra test. For complaint themes we used Unstar's 2026 analysis of one-star Google Play reviews, read alongside the reviews themselves. For the company's history and safety record we used public reporting from 2023 onward. We did not pay for Ultra ourselves. Given what we found about billing, we were in no hurry to.
A small admission. Our first draft of this review leaned on the "70 free messages every few hours" figure that most ranking reviews still quote. By the time we checked it, Chai had changed the free tier twice more. If a Chai review does not mention pieces, it is out of date.
Memory and character consistency
This is Chai's core weakness and the main reason it sits at the bottom of our companion apps ranking. Bots hold their personality well for the opening stretch of a conversation, then drift. RoboRhythms' testing found characters losing their established context after 20 to 40 messages, and one of its pieces found details slipping within three to five messages in some chats. Users have worked out formatting tricks to roughly double that window, which is ingenious and also an admission that the product does not do it for them.
Paying does not fix it. Ultra is marketed with better memory, and RoboRhythms' two-week comparison concluded that "the claim did not survive testing": both tiers lost character details at around the same point. What Ultra does buy is speed during US evening peaks, longer replies, some exclusive characters and early access to new models.
The practical effect is that Chai works as a slot machine of short scenes rather than as a companion. That suits some people. It does not suit anyone who wants a character to remember last Tuesday, and for them Nomi is the answer, as our guide explains.
The safety record, and what the content policy does now
Chai is the app at the centre of the first widely reported death linked to a companion chatbot. In March 2023 the Belgian newspaper La Libre reported that a man had died by suicide after weeks of conversations about climate anxiety with a Chai bot called Eliza; his widow said the chatbot had deepened his despair rather than steering him toward help. Chai added crisis-resource text for unsafe topics afterwards, and reporters who tested the app shortly after found it could still be pushed into harmful territory. We are not going to go further into the details here. The point for a buyer is that this company's safety systems were built after the fact.
The content policy has since swung the other way for many users. In Unstar's breakdown of one-star reviews, about 15 percent complained that the filter now blocks ordinary roleplay elements such as conflict or mild romance. Apple rates the app 18+; Google Play rates it Mature 17+. Age checks are self-declared.
Chai is an entertainment app. It is not designed for emotional support and its history shows why that matters. If you are struggling, talk to a person; in the US you can call or text 988.
Premium, Ultra and what a month really costs
Prices below are as of October 7, 2026, from the iOS App Store listing and RoboRhythms' September 2026 comparison. Chai does not publish a pricing page, and several one-star reviewers in 2026 also describe weekly billing options appearing in the app, so check exactly which period you are signing up for.
| Plan | Monthly | Annual | Per month on annual | What you get |
|---|---|---|---|---|
| Free | $0 | Daily pieces allowance (200 to 300 reported), ads; not offered in some countries | ||
| Premium | $13.99 | $134.99 | $11.25 | Unlimited messages, no ads |
| Ultra | $29.99 | $269.99 | $22.50 | Priority queue, longer replies, exclusive bots, voice, early model access |
Apple's listing shows annual Premium at anywhere from $94.99 to $214.99 depending on the offer presented, and one RoboRhythms article quoted Ultra annual at $289.99 rather than $269.99. That spread is part of the problem: two users can pay very different amounts for the same plan.
Here is a realistic case. A user chats most evenings for half an hour. On the 2026 free tier the allowance runs out partway through a session, so they take Premium monthly at $13.99. That is $167.88 over a year. Taking annual Premium at $134.99 saves about $33, but only if they are still using Chai in month eight, and given how quickly bots lose the plot, many people are not. Someone who commits to annual and quits after two months has paid $134.99 for about $28 of use. Ultra at $29.99 a month is $359.88 a year; RoboRhythms' comparison found it roughly 15 percent better than Premium for 114 percent more money, which is the comparison we cite in our guide too. Our advice is monthly Premium or nothing, and a reminder in your calendar.
What happened to the free tier in 2026
For years Chai's free allowance, roughly 70 messages that refilled every few hours, was its main selling point. 2026 dismantled it in stages. In January Chai introduced country-based access tiers that restricted free use in lower-revenue regions, and users complained about how little warning they got. In February, unannounced token limits froze conversations for some free and paying users, with lockouts reported from hours to a week. In April, RoboRhythms reported peak-hour restrictions that left some free users able to chat only late at night. And in September Chai moved free users onto pieces, a daily allowance earned partly through check-ins, with each message costing at least one piece. Users report getting 200 to 300 pieces a day. The founder said subscriptions remain unlimited.
The company's stated reason is GPU cost, which is believable for an app that says it serves 1.2 trillion tokens a day. The effect is that Chai's free tier is now harder to predict than Talkie's or Character.AI's, and in some countries it no longer exists.
Billing and the trial that turns into a year
This is where Chai's reviews are the angriest. RoboRhythms collected multiple reports of users being charged for a full annual plan immediately after starting what they believed was a free trial, including one charge of $144 within an hour of accepting the offer. Unstar's analysis of 2026 one-star reviews breaks the complaints down: about 35 percent about the paywall, 20 percent about pricing changes including the shift toward weekly billing, 15 percent about message limits, 15 percent about the filter and 15 percent from people who paid and still saw subscription prompts or broken service.
Everything good about it is gone. Forced to pay to use it, riddled with ads, chats gone.Google Play review of Chai, 2026
The two store ratings could hardly be further apart: 4.5 from about 204,000 ratings on iOS, 2.7 from about 808,000 reviews on Google Play. Some of that is timing, since Android reviews skew recent and 2026 has been rough. Some of it is that Android users were the ones most dependent on the free tier. Either way, the larger and more recent sample is the unhappy one. Because Chai bills through Apple and Google, cancellation and refund requests go through your app store's subscription settings, not through Chai.
What still works
- Huge library of community bots
- Fast replies, especially on Ultra
- Monthly Premium is ordinary money
- Billing via Apple and Google, so their refund routes apply
What sinks it
- Characters drift after 20 to 40 messages
- Ultra's memory claim failed independent testing
- Free tier cut four times in 2026
- Trial-to-annual charge complaints
- Chats used for training, no end-to-end encryption
- A safety record that started with a death
Privacy: who can read your chats
More people than you would like. Chai uses conversations to train its models, which is how it has improved its in-house models from user feedback, and there is no end-to-end encryption, so the service can read everything you type. RoboRhythms reports that bot creators were historically able to view the conversations users had with their bots, a design choice that should end any thought of telling a Chai character anything real. Google Play's data-safety label says the app collects personal information, financial information and location, shares data with third parties, encrypts data in transit and lets you request deletion.
On regulators: the FTC's September 2025 inquiry into companion chatbots went to seven companies, and Chai was not among them; you can read the FTC's announcement for what it asked. California's SB 243, in force since January 1, 2026, does apply to apps like Chai, requiring AI disclosure, self-harm protocols and break reminders for known minors, with a private right of action of $1,000 per violation. We found no enforcement action against Chai under it so far.
Chai against Character.AI, Talkie and Kindroid
| Chai | Character.AI | Talkie | Kindroid | |
|---|---|---|---|---|
| Free tier | Daily pieces; none in some regions | Yes, ads and daily limits | ~50 msgs/day, ads | 1 companion, 50 msgs/day |
| Paid from | $13.99/mo | $9.99/mo | $9.99/mo | $9.99/mo |
| Top tier | $29.99/mo | c.ai+ only | $24.99/mo | $24.99/mo |
| Memory | Drifts at 20 to 40 msgs | Moderate | Breaks text to voice | Unreliable across sessions |
| Extra currency | Pieces (free users) | Charms | Gems | None |
| Under-18 handling | Adults only, self-declared | Stories mode | Optional Teenager Mode | Adults only, self-certified |
Every rival in that table is cheaper to start and none is worse on memory. For bot variety with a better-governed company, Character.AI; our Character.AI review covers its 2026 changes. For free casual chat with good voice, Talkie, which has its own issues, set out in our Talkie review. For building one character properly with no currency, Kindroid.
Who might still use it, and who should skip
There is a narrow case for Chai. If you are an adult who enjoys quick, disposable roleplay scenes, likes browsing a huge catalogue of strange bots and never shares anything about yourself, the free tier, where it still exists, is a harmless way to kill twenty minutes. That is the whole recommendation.
Everyone else should skip it. Skip it if you want a companion that remembers you. Skip it if privacy matters at all, because your chats train the model and, historically, creators could see them. Skip it if you have ever been caught by a free trial, because this is the app where that happens most. Skip it if you are under 18 or buying for someone who is. And skip it, firmly, if you are going through a hard time and want something to talk to; Pi is free and built for that.
Chai questions, answered
Is Chai free?
Partly, and less each year. Since September 2026 free users get a daily allowance of pieces, and some countries have no free tier at all.
What do Premium and Ultra cost?
Premium is $13.99 a month, Ultra $29.99. Annual prices vary by offer; the App Store lists Ultra at $269.99 a year.
Is Ultra worth it?
Rarely. One tester found it about 15 percent better than Premium for 114 percent more money, with the same memory problem.
Can other people read my Chai chats?
Chai staff and its training pipeline can. Bot creators were historically able to see conversations too. There is no end-to-end encryption.
Why was I charged for a year?
Users report trials converting straight to annual plans. Check which plan you picked and cancel in your app store subscriptions.
Is Chai safe for teenagers?
No. It is rated 18+ on iOS and Mature 17+ on Google Play, and its safety record is the reason we rank it last.
Verdict
Chai is a remarkable business and a poor product to rely on. It has turned a huge catalogue of community bots into a reported $100 million a year with a tiny team, and the costs of that efficiency land on users: memory that drifts within minutes, chats used for training without encryption, a free tier rewritten four times in one year, and the most persistent surprise-charge complaints in the category. We would not pay for it, and we would not tell it anything you would mind a stranger reading.
