Chub AI vs Character AI: which trade-off suits you?

Character AI allows no NSFW content, full stop. In return it gives away a lot: its FAQ promises free and unlimited messaging for all users, on web, iOS and Android, with ads and a slow mode when traffic is heavy. It is the generous, careful one of the pair.

Chub AI goes the other way. Its content policy allows NSFW roleplay, but the free start is thin. There is no standing free plan, only one-time trial credits worth a few dozen messages, sent out to new users regularly.

After that you either pay for Mars at $20 a month or host a model yourself through Kobold or Ooba, which is free if you have your own setup. It runs on the web only. Chub AI also lists paid API access, which Character AI does not offer, though that matters only if you build your own tools.

That is why I see Chub AI as a Character AI alternative mainly for one reader: someone who hit Character AI's content line and wants it gone. If that is not you, I struggle to see why you would trade unlimited free chat for trial credits and a $20 plan. Honest answer, not a knock on Chub AI.

The comparison table after this section lays the two apps out side by side, row by row. My tip: look at the content row and the free tier row together, since the whole choice lives there. Memory and group chat come out close, so they rarely decide it.

For the full story on the paid plan, the trial credits and the self-hosting route, see my Chub AI review, which goes further than this page can.

Chub AI is said to hold a character's voice well across many characters, yet other reviewers report dialogue confusion and repetition, including the AI writing both sides of a conversation. My call: a draw on quality, with Character AI's pins as the tiebreaker.

The one practical difference is where you can reach your characters: Character AI on web, iOS and Android, Chub AI only in a browser. If you chat on the sofa more than at a desk, that small point favours Character AI.

Chub AI's Imagine tool reportedly looks like a photo at first sight but clearly AI-made up close, with inconsistent likeness. Content is the real split: Chub AI allows NSFW roleplay, Character AI allows none. That one row matters more than everything else here.

Neither is kind to a change of heart. More on the free app's plans sits in my Character AI review.

Upgrading costs little. The lite plan at $4.99 cuts ads and adds 30 memory pins plus chat customization, and c.ai+ at $9.99 drops ads and slow mode entirely, with unlimited premium chat styles and premium support. Billed yearly, c.ai+ is $94.99 instead of $119.88, a 21% saving that I would take once the app has proven itself.

Where Character AI loses readers is the content policy, which allows no NSFW material. For many people that is fine, even welcome. For those who find it frustrating, no plan changes it, so do not pay hoping it will. Renewal is automatic until you cancel, so note the date if you only want c.ai+ for a month.

Two smaller catches. Long chats can drift, with a promise from ten messages earlier forgotten despite Auto Memories, going by one review. And one reviewer describes two different cards being declined repeatedly at c.ai+ checkout over three weeks. If you run into that, the app stores are another way to buy, with refunds then handled by Apple or Google.

Cancelling on the web runs through Settings > Account > Manage and on to the Customer Portal.

My full list of app matchups puts Character AI against several other names if you want a wider view.

• Starting free: Free tier
• Lowest price: $4.99 monthly ((c.ai) lite)
• Allowed: unconfirmed
• Runs on: web, ios, android

The pricing is refreshingly simple: one plan, Mars, at $20 a month. For that you get every Chub language model with no cap, Soji among them, plus unlimited voice and multimedia generation and first access to new models. I like that nothing is metered on Mars.

What I do not like is that there is no cheaper step and no annual plan on file, so $20 is the entry price, full stop.

The free side is where Chub AI is weakest. There is no standing free plan, only one-time trial credits worth a few dozen messages, which new users are sent regularly. The genuinely free route is self-hosting a model through Kobold or Ooba. That suits tinkerers; most readers will find it a lot to ask just to chat. Custom characters and group chat are both listed, so the hub side matches Character AI.

Mind the refund rule before you subscribe. A secondary source quotes it as no refunds outside exceptional cases, and says the policy is firm. Cancelling is described as self-serve. I would use the trial credits fully before paying, so the $20 goes on something you already know you like.

It is web-only, with no app for either phone store on file, so on a phone you open it in your browser.

To see how these facts are gathered and weighed, read how I check the apps.

• Starting free: Free tier
• Lowest price: $20.00 monthly (Mars)
• Allowed: mature chat permitted
• Runs on: web

At $0, Character AI gives you unlimited messaging with ads and slow mode. Chub AI gives you one-time trial credits worth a few dozen messages, plus free self-hosting if you run your own model. For most readers, only one of those is a free plan you can live on.

At the entry level, Character AI's lite plan is $4.99 a month. Chub AI's only plan, Mars, is $20, which is $15.01 more. Against c.ai+ at $9.99, Mars costs $10.01 more each month. Twelve months of lite at $4.99 come to $59.88, just under three months of Mars at $60.

Over a year the gap grows. c.ai+ billed annually is $94.99. Chub AI has no annual plan on file, so 12 months of Mars at $20 comes to $240, which is $145.01 more than a year of c.ai+. That is a real sum, and I would only pay it for what Chub AI offers that Character AI does not: a policy that allows NSFW roleplay, and unlimited voice and multimedia generation on Mars.

So my reading is simple. If the content line does not bother you, Character AI is the cheaper app by a wide margin at every level. If it does, $20 a month for Mars is a fair price for unlimited models and media, and I would not call it overpriced. Just do not pay it by default.

And if images and video are the real reason you are shopping, compare apps built around them. My Candy AI vs OurDream AI page does that math with coin allowances included.

Its trial is short, in the same spirit as Chub AI's credits. The figure varies by source: 5 messages in total in one, and 3-5 messages with 3-5 images in the dated check from 2026-09-22.

Price is its strongest card. The yearly plan is €47.88 upfront, which is €3.99 a month and well under both c.ai+ and Mars, and a 70% sale on it was listed on 2026-09-23. Whatever length you choose, 100 tokens arrive each month, and the 3-Month Plan is the middle option at €26.97, or €8.99 a month.

Two things to weigh: refunds for non-EU/UK buyers close 24 hours after payment, and the bill shows as EverAI, which I find discreet.

If the line does bother you, that is the moment Chub AI makes sense, and I would move in this order:

• Spend the one-time trial credits on Chub AI before paying anything.
• If you are handy with your own setup, try free self-hosting through Kobold or Ooba first.
• Only then subscribe to Mars at $20 a month, knowing refunds are limited to exceptional cases.
• Keep Character AI's free plan for SFW chats; there is no reason to cancel something free.

The part I like about this route is that you never pay to discover a preference. Every step gives you real information before any money moves. And if you mostly chat on your phone, remember that Chub AI is web-only, while Character AI also has iOS and Android apps.

And if what you actually miss on both apps is a companion who remembers you over weeks rather than a library of characters, look elsewhere. My Candy AI vs Nomi AI comparison is the better next read, with Nomi AI's free plan of 50 messages a day as the easy first step.
