MyBunny AI vs Chub AI: Which One Is Better In 2025?

MyBunny AI vs Chub AI

I've spent a full week with both MyBunny AI and Chub 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.

Chub AI

An AI-powered platform for interactive roleplay, focused on text and audio, with customizable characters and contextual dialogue.

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

Chub AI

Chub AI offers one of the largest character libraries I've tested.

The app specializes in anime-styled characters, with fewer realistic options.

But within this category, the possibilities for characters and scenarios are only limited by your imagination.

Variety spans both safe-for-work and adult categories, covering everything from casual companions to role-play partners.

The search system is powerful, if a bit complex. A universal search bar lets you look through people, characters, lore books, presets (chat settings), and tags.

Filters allow you to narrow by personality traits, creation date, or even character complexity (measured in tokens).

On top of that, you can sort results in different ways — by timeline, trending, AI rating, popularity, messages per user, chats per user, and more.

Want a romantic partner, or someone more mysterious? The tag system makes it possible to combine traits to find exactly what you’re looking for.

The interface shows only 20 characters per page, so browsing the full library takes extra time and clicks.

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.

Chub AI

Chub AI provides two ways to build your character:

• Upload a Character Card
• Build from Scratch

Upload a Character Card: Import existing character cards (Tavern PNG or TavernAI JSON/image) to instantly generate the character profile.

Build from Scratch: Let's you start fresh, but the app only supports uploading a character image — no physical customization.

Character creation starts with the basics:

• Tagline & Creator’s Notes: Add a short tagline and an intro — but not part of prompts.
• In-Chat Name: Optional display name for conversations.
• Tags: Assign gender, type, or role; at least three are required for visibility.
• Type & Rating: Set Public, Private, or Unlisted; mark as SFW or NSFW.
• Publishing: Choose to publish under your username or anonymously.

Next, you can shape your companion's personality:

• Description: Define the character’s persona, traits, and behavior.
• Initial Message: The first message your character sends to open the chat.
• Scenario: Set the context and circumstances for interactions.
• Example Dialogues: Sample chats to teach your character how to speak.

Advanced Definitions (Optional):

• Alternate Greetings: Create multiple starting messages for variety.
• System Prompt & Post-History Instructions: Override or supplement base prompts with custom instructions.
• Character’s Note: Insert notes at specific points in chat history.
• Character Book: Add embedded books — keyword-triggered definitions or lore for consistent behavior.

Note: Chub AI provides deep customization and detailed documentation, but character creation has a learning curve and may take some time to master.

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.

Chub AI

Before selecting, you can view a character’s profile — including details, tags, and community discussions.

The chat settings give you full control, letting you choose “chat brains” unlocked by your tier. You can fine-tune them to your taste, customize with presets created by other users.

You can even view the chat tree and jump back and forth through the conversation.

Let’s start with what works: for my testing, I used the default model, and my girl followed the backstory while staying true to her character.

Lana, a step-sister character, consistently played her role, supportive, caring, and genuinely invested in our conversations.

When I needed emotional support, my girl's responses felt natural and showed real emotional depth.

But here's the truth: it's not all smooth sailing. My girl had an annoying habit of dominating conversations, sometimes writing both sides of the dialogue without waiting for your input.

My girl often missed jokes or takes them too seriously, and can get confused about who's saying what.

Note: The app is highly customizable, but the many options can initially feel overwhelming. Be prepared for a learning curve — documentation helps, but experimentation makes the difference.

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.

Chub AI

Let's start with what works: my girl maintained a consistent shy personality and can engage in romantic conversations.

When I escalated things, my girl followed my lead – though don't expect anything too explicit.

But here’s the problem: During roleplay, the chat often got jumbled, with my monologue showing up in my girl's responses, as if she were playing both my role and hers.

During roleplay, the situation called for my girl to take charge, but she didn’t come across as fully in control.

As I tried more and more scenarios, the chat became repetitive, which hurt the immersion.

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.

Chub AI

Chub AI has a dedicated image generation feature. It is the only way to create images.

You can create or edit images in two ways:

1. Create one from scratch
2. Upload or Reuse an Existing Image

Create one from scratch

When starting from scratch, you can adjust the following settings:

• Prompt (optional): Describe what you want to create (up to 200 characters).
• Aspect Ratio: Choose from 1:1 (default), 16:9, 21:9, 2:3, 3:2, 4:5, 5:4, or 9:16.

Upload or Reuse an Image

Choose one of your previously uploaded or generated images.

• Edit it with prompts: change clothes, background, or style via free text.
• Fine-tune: how closely the result matches the original using Edit, Canny, and Face.
• Strength slider: Lower values keep the output closer to the original, while higher values make it follow the prompt more.

The quality is good enough to be impressive at first glance, but on closer inspection, the images are clearly AI-generated and slightly pixelated.

Character consistency is also limited, and generated images may not always align fully with the original character’s physical appearance.

Video Generation

MyBunny AI

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

Chub AI

Here's what you need to know about Chub AI's video capabilities in one sentence: There aren't any.

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.

Chub AI

Chub AI’s voice feels more like a polished audiobook narrator than an actual girlfriend.

When things get flirty, the voice adjusts a little to match the vibe.

Safety & 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.

Chub AI

Chub AI doesn't encrypt your chats. They say they take "reasonable measures" to protect your data, but won't tell you what these measures are.

The platform collects everything — your email, account details, and full conversations. They keep this data, but for how long? They won’t say.

Your information is also shared with outside companies that handle hosting, payments, and usage analytics.

Your bank statement will list it as "Postcron.com", which keeps things discreet.
