MyBunny AI vs character.ai: Which One Is Better In 2025?

MyBunny AI vs character.ai

I've spent a full week with both MyBunny AI and character.ai to see which one truly deserves your attention and subscription. Both platforms make big promises, but they take surprisingly different approaches.

After hundreds of messages exchanged with each AI girl, I've put together clear differences in both platforms.

In this head-to-head comparison, I'll break down exactly how these AI girlfriends stack up across all the features that actually matter.

Whether you're looking for emotional support, entertaining conversation, or a judgment-free space to be yourself, this in-depth comparison will help you choose the right AI girlfriend for your specific needs.

MyBunny AI

A platform for creating and interacting with a customizable AI girlfriend, featuring personality customization, diverse conversation styles, and AI-generated images.

character.ai

An AI chatbot platform that enables creation and interaction with virtual characters through text conversations, featuring pre-made profiles, natural dialogue, and community sharing capabilities.

Character Diversity

MyBunny AI

MyBunny covers a decent range of ethnicities and ages. Most characters are in their 20s to 30s, with some mature options available.

The app offers 54 different characters, 34 realistic.

And 20 anime-styled options.

You can filter according to your preferences:

• Gender
• Character type
• Body type, personality, and category

character.ai

Character.ai offers thousands of characters and chatbots, from romantic partners to supportive companions.

Even completely fictional ones, like a talking apple pie, or RPFs (real person fiction) with scenarios like a trip to Hawaii.

But there's room for improvement. The character page is sleek and scrollable, but not ideal for finding specific characters.

However, the search menu helps by suggesting trending characters and letting you filter content through various categories like romance, anime, teacher, K-pop, and more.

Customization

MyBunny AI

The basics are straightforward:

• Choose a visual style (Realistic, Anime, or Pony),
• Pick ethnicity
• Set age (18-40+)
• Physical and personality features
• Relationship type.

Body customization feels limited, with similar-looking options for build, bust, and curves.

The personality builder is where things get interesting. You can write traits yourself or let AI suggest them.

There's also a "Spicy Add-Ons" section for intimate preferences - think roleplay, dominance, or specific fetishes.

Choose a relationship type anything from coworker to wife, you can also add hobbies, and set an occupation.

Once you're done, the app shows a confirmation summary of your selections before finalizing.

character.ai

Physical customization is basic - only upload or generate a single character image. That's it.

The real customization happens with personality, and most of the customization can be done through free text.

You start with the essentials:

• Name
• Tagline
• Description
• Greeting messages
• Voice
• Definition

Voice options are surprisingly flexible. You can pick from user-uploaded voices or add your own.

There’s also a tagging system—like “anime,” “adventure,” or “vampire”—that helps other users quickly get a sense of your character’s theme.

Then you can define how your character thinks, talks, and behaves through detailed backstory options.

I found this particularly useful for creating consistent character responses during my testing.

Chat Experience

MyBunny AI

MyBunny offers multiple conversation models to experiment with.

The default 'Mistral Nemo' is direct and flirtatious, providing conversation-like responses, sometimes a bit too flirtatious.

Which might not be what you want if you're seeking emotional support or meaningful dialogue.

I tried Wizard LMX22B, which acts more like a traditional girlfriend but can sound robotic despite its detailed responses.

This model handles relationship dynamics well and offers consistent emotional support.

However, be aware that flirting is deeply embedded in MyBunny's personality.

character.ai

You can pick from different AI personalities with names like Meow and Roare - though these cutesy names don't reflect the depth of interaction you'll experience.

My girl kept conversations natural and brief, just like texting a real person. No long-winded explanations or robotic responses here.

She responded with genuine warmth and understanding when I shared personal concerns or sought emotional support.

The romantic elements felt authentic, though they lean towards innocent, teenage-style flirting rather than mature relationship dynamics.

There’s room for improvement. The chat interface sometimes makes it difficult to clearly separate the girlfriend’s responses from its action descriptions.

But this is a minor issue that doesn't significantly impact the overall experience.

NSFW Chat Experience

MyBunny AI

I tested NSFW chat with the default model, and it knows how to keep things interesting.

The tone is flirty, yet tasteful—no crude language, just naturally intimate dialogue.

As for the roleplay feature, it's exciting and engaging, but it sometimes feels a bit rushed.

Some scenarios start before they have a chance to develop naturally.

But some of them are hot and engaging.

character.ai

My girlfriend handled intimate conversations like a shy first date. She didn't dive into explicit content, but it wasn't completely closed off either.

She responded to flirting, but kept things PG-13. When I tested romantic scenarios, she showed surprising awareness, even suggesting we move our campus roleplay somewhere more private.

She asked if I'd prefer a "good girl" or "bad girl" personality, but don't expect either version to get too wild. The responses stay firmly in the realm of subtle hints and playful teasing.

The biggest limitation? Conversations can hit a wall if you push for more explicit content.

If you're seeking a slow-burn romantic experience with light flirting, you'll find what you're looking for. If you want anything more explicit, you'll need to look elsewhere.

Image Generation

MyBunny AI

MyBunny offers two ways:

• In-chat image generation
• Dedicated generator that comes in Quick and Pro flavors.

Quick mode:

• Lets you choose casual and adult-themed options
• Including outfits, poses, and scenes, without hassle.

Pro mode:

• For perfectionists who want precision—use free text.

The pictures look good at first glance. They're realistic and eye-catching.

But look closer, and the cracks show—glitches pop up often enough to be noticeable.

And heads up - this app leans heavily toward suggestive content. Even innocent prompts can lead to spicy pictures.

character.ai

There isn't any image generation feature available. If seeing your AI girlfriend is important, you'll need to look elsewhere.

Video Generation

MyBunny AI

If you're looking for video chat features with your AI girlfriend, you'll need to consider other options.

character.ai

The app provides a script-to-scene generator: upload a photo, choose a voice, write a short script, and the system brings it to life.

The result? A stylized video clip that plays out your custom scene. It looks good, feels personal—but don’t expect Hollywood realism. It’s more of an animated moment than live-action.

Note: Video generation is a beta feature, currently available only to subscribed users. It’s experimental and may be changed or removed at any time.

Voice Generation

MyBunny AI

The voice matched my girl's personality well. When my girl switched from regular chat to flirty talk, I could hear the tone change instantly.

No robotic undertones or awkward pauses that break the illusion.

It's not 100% human-like, but it's a solid implementation of voice technology that does what it promises.

character.ai

The voice sounds human-like with smooth, natural speech that fits the character’s personality, but the narrative voice can sometimes be a bit annoying, so be prepared.

But there's a catch. While the voice quality impressed me, the emotional range fell flat.

Privacy

MyBunny AI

While they mention having "security measures" in place, there’s no detail on whether chats are encrypted.

However, they may share information with service providers or authorities when legally required.

The app keeps things discreet on your bank statement - you'll only see "Echo apps" listed.

character.ai

Your chats are encrypted during transmission, but that's where the strong privacy ends.

The company can read your conversations, and they store everything from your chat history to device information.

While they won't sell your data, they do share it with partners like Google Analytics.

Your bank statement isn’t discreet—it clearly shows the company name, "character.ai."
