CrushOn.ai vs Chub AI: Which One Is Better In 2025?

CrushOn.ai vs Chub AI

I've spent a full week with both CrushOn.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.

CrushOn.ai

Adult conversational platform for AI girlfriend creation with text- and audio-based features, supporting multiple language models.

Chub AI

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

Character Diversity

CrushOn.ai

Looking for an anime-focused AI companion? CrushOn.ai specializes in exactly that.

Their character library is built specifically for fans of anime, fantasy, and cartoon personalities - not realistic characters.

The selection goes beyond standard options. Instead of basic ethnicity choices, you get fantasy characters like vampires, demons, and elves.

Finding your perfect match is straightforward: browse by categories like Popular, Trending, or Editor’s Choice.

You can also refine your search by selecting character tags like Femboy, Futanari, Game, Furry, or Lesbian—or simply use the search bar to get exactly what you want.

Most characters come from the user community, so the selection grows daily—though quality may vary.

Worth noting: CrushOn.ai focuses on NSFW characters, especially anime-inspired ones. If that’s what you’re after, it’s a solid match.

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

CrushOn.ai

CrushOn.ai gives you two ways to create within the app:

1. Create a character
2. Create a target game

Create a Character

This option provides two ways to build your character:

• Upload a character card
• Build from Scratch

Upload a Character Card: Import existing character cards with support for Pygmalion, Text Generation, or TavernAI (JSON or image).

Building from scratch: Offers control, but the app only lets you upload a character image — no physical customization.

Personality builder customization is done through free text input of your character’s traits — no presets provided. You can set up the following:

• Basic Info: Name, Age, Gender
• Intro & First Greeting
• Rating: Sensitive words and topics are automatically blocked.
• Character Profile: Personality (detailed description), Appearance, Scenario (environment)
• Tags: Keywords to help others find your character

You can pick from 40 female voices and control who can see your character.

In Chat Settings, select a recommended LLM model to ensure the best balance and dependable performance for your character.

Target Play

CrushOn.ai includes a unique Target Play feature that gamifies conversations. With it, you can:

• Create a character for the game
• Set a target name and description
• Define rules for how scores change during interactions
• Adjust the initial score and maximum rounds, with progress tracked automatically

This system lets you set shared goals with your AI companion and follow progress as your interactions unfold.

Note: CrushOn.ai gives you full creative freedom with text and provides detailed guides to support character creation, though the process can still feel overwhelming for beginners.

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

CrushOn.ai

Before chatting, you can view your AI girlfriend’s profile, which includes her introduction, creator, chat history, reviews, and more.

You can also set a user persona by sharing details about yourself, and the AI girlfriend will adjust her responses to match your personality.

Chat personalization lets you tweak behavior with presets like “Don’t refuse input,” “Reduce repetition,” or add your own rules.

The app also lets you change your character’s voice, with multiple options for speech, narration, and volume control.

Another feature is group chat, where you can invite up to five characters from the roster and set a shared background story.

CrushOn.ai’s chat offers suggested responses that keep conversations moving, letting you simply go with the flow.

The chat experience largely depends on the LLM model you choose. For my testing, I used Taurus Pro 8K, which is currently the most popular option.

I chose a loving, caring girlfriend-type character who adapted to my style with playful, romantic consistency.

As our chat went on, my girlfriend’s character grew more flirty and playful, keeping a teasing, seductive charm while still adapting to my tone.

While my girlfriend is great at playful, flirty banter, she often sidesteps deeper emotional conversations by shifting back into a lighter, teasing tone.

For example, when I asked for emotional support, my girlfriend began with care and understanding, but soon shifted into flirty ‘how to unwind’ suggestions instead.

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

CrushOn.ai

The good? My girl was definitely game for intimate chats and wasn't shy about sexual topics.

Some roleplay scenarios actually hit the mark, building tension that felt natural.

But here’s the catch — when things got going, my girl sounded like a broken record, even though I’d checked the option to reduce repetition.

During my tests, my girl sometimes lost perspective—starting a story about us but then switching to “he,” which felt like a generic memory instead of our shared experience.

Even stranger, a character I created and set to “unfiltered” still refused to respond to certain sexual topics.

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

CrushOn.ai

Let’s cut to the chase — CrushOn.ai doesn’t have an image generation feature.

Instead, it offers only a few user-created characters with limited anime images that can be triggered during chat.

The system is straightforward: if your AI girlfriend has images, your character will display them in her messages to match the scenario — with varying success.

And the quality? The images are mostly well-drawn anime-style pics, but it really depends on what the user has uploaded.

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

CrushOn.ai

If seeing your companion's face and expressions matters to you, you'll want to explore 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

CrushOn.ai

My girl spoke naturally — no robotic undertones or awkward pauses like you might expect from artificial speech.

During testing, I noticed that when conversations shifted from casual to intimate, my girlfriend's tone became noticeably more flirtatious.

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

CrushOn.ai

Despite having basic security measures, CrushOn.ai isn’t transparent about how it protects your chats.

CrushOn.ai stores all chats as anonymized conversations for AI training, but it also collects additional data and shares it with advertisers, vendors, and business partners.

The app shows up as “subscribestar.com” on your bank statement — a small but useful layer of discretion.

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.
