This is the comparison people run when Character AI stops feeling like enough. Character AI is the mainstream option with a huge character library and a filter that will not move. Pygmalion AI grew out of the open-source Pygmalion model project and hands you the controls instead. They look similar on the surface and behave very differently once you spend an evening on either.

Pygmalion AI in brief
Pygmalion is the platform for people who want to see the machinery. You browse an Explore library of community character cards with tags, ratings and download counts, then open a chat that streams responses and narrates scenes properly. Behind that sits a settings panel most sites do not offer at all: model selector, samplers, author note, include-names and use-all-info toggles.
- Model roster from fast free models up to premium 131k-context options such as Hermes IV 405B and GLM 4.5 Air
- Grimoire long-term memory system on paid plans
- Portable versioned character cards you can build, import and export
- Free plan with unlimited free models, though memory is squeezed from 16K down to 8K
The honest downside is that all of this is a lot if you only want to point and flirt. The interface is functional rather than polished, community art quality varies, and it is text-first, so there are no photorealistic images or video of your companion.
Character AI in brief
Character AI is the one everybody tries first. The library runs into the millions of user-made characters, the app asks nothing of you, and the chat is good enough that it built the category. What it will not do is bend on content. The NSFW filter is still in place in 2026, and roleplay that drifts toward mature territory gets redirected.
- Very large character library covering essentially every fandom and archetype
- Basic memory within a session, with enhanced memory sold on the paid tier
- c.ai+ at $9.99 per month or $94.99 per year, which removes ads and adds priority access, unlimited voice calls and unlimited swipes
- Free tier now carries mid-chat ads and gates swipe regeneration behind a Charms currency
For a lot of people that trade is fine. If you are here because a scene keeps getting cut short, though, no plan on Character AI fixes it, and that is the single reason most of this comparison’s traffic exists.

Pricing compared
| Plan | Pygmalion AI | Character AI |
|---|---|---|
| Free | Unlimited free models, 8K memory, possible ads and slower generation | Full library, mid-chat ads, Charms-gated swipes |
| Entry paid | $6.50 per month, Low-Cost (Grimoire memory, 16K context, faster generation, 150 premium messages) | $9.99 per month, c.ai+ |
| Top plan | $17.99 per month, Premium (unlimited models, higher context, fastest generation) | $94.99 per year, about $7.92 per month |
| Extra costs | None, caps are message-based | Charms currency on the free tier |
Pygmalion’s limited free tier also gives 200 messages per day on better models, which is more generous than the word free usually means in this category.
Pros and cons
Pygmalion AI
- Pro: genuinely usable free tier, not a three-message tease
- Pro: the best in-site model variety in the category, and it is clear about what a plan buys
- Pro: deep card system and settings normally reserved for separate front-ends
- Pro: portable, exportable cards and an active community
- Con: the depth is a lot for casual users
- Con: functional rather than glamorous interface, and uneven community art
- Con: message caps and cooldowns push heavy users to pay, and free memory is short
Character AI
- Pro: the largest character library available anywhere
- Pro: nothing to configure, which is why it is most people’s first stop
- Pro: cheap entry point at $9.99 per month, cheaper annually
- Con: the filter is the product’s defining limit and no plan removes it
- Con: ads and a Charms currency now sit on the free tier
- Con: memory gains on the paid tier are widely described by users as small
Which one should you pick
- You want a specific fandom character right now: Character AI, on library size alone.
- Your scenes keep getting redirected: Pygmalion AI. That is the whole reason to switch.
- You want to choose the model: Pygmalion AI, which is the only one of the two that lets you.
- You want long collaborative stories: Pygmalion AI, with Grimoire memory on a paid plan.
- You want to spend nothing: Pygmalion AI has the better free experience.
- You want pictures of your companion: neither. Both are text-first, so start with our roundup of apps with real image generation instead.

Common questions
Does Pygmalion AI allow adult roleplay?
Pygmalion is not marketed as an adult platform. It is a general roleplay site with relatively unfiltered models, so mature roleplay is possible if you steer it. The framing is fiction-first rather than adult-first, which is a real distinction if explicit content is your main goal.
Has Character AI removed its filter?
No. The filter is still in place in 2026, and it applies on the paid tier as well as the free one.
Is Pygmalion AI hard to use?
It is harder than Character AI, and that is deliberate. The model selector, samplers and author note are the point of the platform. If you never open the settings panel you are paying for depth you are not using.
