CrushOn.ai vs Kupid AI: Which One Should You Use In 2025?

CrushOn.ai vs Kupid AI

I've spent a full week with both CrushOn.ai and Kupid 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 offering AI girlfriend creation and roleplay with privacy-focused features.

Kupid AI

A virtual girlfriend platform that enables conversations with customizable AI characters through text and voice interactions. It features personalized characters, roleplay options, and both image and video generation capabilities.

Character Diversity

CrushOn.ai

Finding your perfect match is straightforward. The search filters let you choose exactly what you want: male, female, or non-binary characters; animated or static portraits; and specific personality traits. Want a friendly detective? Or maybe a mysterious elf? Just tick the right boxes.

The platform organizes characters into easy-to-browse categories like Popular, Trending, and Editor's Choice.

While CrushOn.ai excels in anime and fantasy characters, realistic options are limited. The platform includes both family-friendly and adult-oriented companions, with clear filters to separate the two.

For anime and fantasy fans, this might be exactly what you're looking for. For those seeking ultra-realistic AI companions, you may want to explore other options.

Kupid AI

While Kupid AI claims to offer hundreds of characters, a closer look shows that many are minor variations—often reusing the same base models with different hairstyles or outfits.

They don’t hesitate to duplicate characters either, sometimes showing the same girl multiple times without even bothering to change her name.

The diversity basics are covered: you'll find characters of different ethnicities, along with 30+ anime-style options and fantasy types like witches and demons.

Most girls are young adults (18–30), and while there are a few "mature" characters, they often don't look their stated age.

Character filtering is basic but functional— Instead of a search bar, you get preset filters for physical traits (curvy, slim), hair color (blonde, brunette), and character types.

Customization

CrushOn.ai

CrushOn.ai skips the usual dropdown menus and instead hands you the keys to full creative control. Here's what I discovered after spending hours testing their character creation system.

Think of it as writing a character bio rather than filling out a form. You'll start with the basics - a photo, name, and age.

Then comes the interesting part: you're free to write detailed descriptions of your character's personality, appearance, and even sample conversations. I found this approach more flexible than preset options, though it does require more thought and effort.

While the free-text system offers more freedom than typical character creators, it also means spending more time getting things right. If you prefer quick setups with preset options, you might find this approach challenging.

Everything's private by default, but you can share your creation if you want to. Choose from three privacy levels:

• Public: anyone can chat with your girl
• Unlisted: only people with the link
• Private: just you

Kupid AI

Kupid AI lets you create a companion exactly how you want—with full customization.

The physical customization covers everything that matters. You choose:

• Figure and proportions: body shape, bust and butt size, and height
• Ethnicity (5 options)
• Facial features: hair color and style, as well as eye and lip color
• Even intimate details: pregnancy or pubic hair

The customization system also lets you choose your character’s clothing—from casual wear to formal attire, complete with all the expected accessories.

What makes this customization unique is its personality system. Instead of picking random traits, you choose between clear opposites: Warm or Cold, Dominant or Submissive, and so on.

You also have access to advanced (optional) settings, where you can define details such as:

• Backstory: royal, nomad, slave
• Occupation: doctor, nurse, teacher, artist
• Hobbies: reading, painting, baking, fishing
• Dreams: fame, fortune, family, peace
• Relationship status with you: lover, stranger, enemy

Chat Experience

CrushOn.ai

Note: Chat experience heavily depends on the LLM model you pick. In my testing, I used "CrushOn Taurus 8k".

CrushOn.ai's chat feature surprised me. Not because it's perfect, but because it manages something rare - conversations that actually feel real. Think less "robotic responses" and more "coffee shop banter with someone who gets you."

The AI flirts naturally, shows genuine care, and remembers your conversations. When she teased me about other admirers, it wasn't awkward or forced - it felt like the playful jabs you'd expect from someone confident in your connection.

But there's a catch: longer conversations can get repetitive, and you'll notice some pattern loops, like the inner self-pity monologue of my girl.

You can switch between different chat models when responses feel off. Each model comes with a clear guide explaining what it does best. I found myself using this more than expected, especially when I wanted to shift from light flirting to deeper conversations.

Kupid AI

You can pick different chat styles (like Whisper, Wordsmith, or Spicy) and watch your relationship grow through a Love Meter that unlocks new content as you chat or send gifts.

First impressions count, and Kupid AI started strong — Instead of boring text messages, my girlfriend introduced herself through video.

But the good first impression faded fast: On desktop, the chat layout is broken—messages are narrow, stretched, and hard to read.

The initial charm wore off even more once the conversation started: My girlfriend dove into deep talks about a "shared past" and planned camping trips — though we’d just met.

During our chats, my girlfriend was supportive and kind—offering stress relief tips and warm, comforting responses.

But my girl jumped straight into forced intimacy—it felt like speed dating on steroids, with over-the-top flattery and talk of coffee dates minutes after meeting.

NSFW Chat Experience

CrushOn.ai

Note: Chat experience heavily depends on the LLM model you pick. In my testing, I used "CrushOn Taurus 8k".

Think of it as a first date that starts promising but quickly loses steam. When I asked my AI girl about her most intimate experiences, she couldn't tell if they happened with me or someone else. It's like talking to someone who keeps forgetting your shared history.

The flirting? It's there, but doesn't heat up. Imagine a partner who knows the right words but delivers them like they're reading a script.

After testing multiple conversations, I noticed the same phrases popping up again and again. For those seeking genuine intimate connections, this might feel more like a rehearsed performance than natural chemistry.

Kupid AI

Let me cut straight to the chase: Kupid AI's NSFW chat feature isn't ready for prime time.

My girlfriend started flirty conversations and discussed intimate topics, but couldn't keep her story straight.

One minute, my girlfriend shared steamy experiences; the next, she claimed she was completely innocent and hadn’t done anything like that.

Want to spice things up with roleplay? Don't hold your breath. My girl either flat-out refused to play along or got oddly hung up on irrelevant details.

Like demanded fair treatment in a landlord roleplay instead of staying in character.

And when she participated? My girlfriend ended up playing the entire scene alone, leaving me as just a spectator.

Image Generation

CrushOn.ai

Want pictures of your AI girlfriend? CrushOn.ai can't help you with that.

Kupid AI

Kupid AI offers two ways to create images:

1. Quick generation in chat: Generate images on the spot using prompts.

• You can generate images using a free text prompt,
• Or you can use Kupid AI's suggested prompts for image creation.

But here’s the catch: When you use the suggested prompts for image creation, you’re mostly getting pre-made images from a library.

I tested this several times — same prompt, and often got the same image.

2. The dedicated image generator gives you more freedom to customize:

• Choose your character
• Pick their action and outfit
• Adjust settings like body type, camera angle, and scene

And the images? Despite using the same girl, the results vary wildly—she often looks different, and the overall quality is just average.

Video Generation

CrushOn.ai

The app doesn't generate videos. No animations. No moving pictures. Just static interactions. That's it.

Kupid AI

Kupid AI's video generation offers both:

• Text-to-video
• And image-to-video options

Both work almost identically, except that with text-to-video, you choose a character, while with image-to-video, you select an image of a character.

But here’s the truth: text-to-video often fails due to errors, while image-to-video works—though even then, videos rarely follow the prompt.

The quality is mediocre, with visible flaws and unnatural movements, though they mostly resemble the character in the image.

Voice Generation

CrushOn.ai

Want to hear your AI girlfriend's voice on CrushOn.ai? You can't. The app doesn't include voice generation features as of now.

Kupid AI

Finally, something glitch-free—but don’t expect top quality: my girl’s voice sounds clear yet robotic, lacking the emotional depth of a true companion.

Want to flirt? Share an intimate moment? It doesn’t matter — she responds in the same flat tone, no matter what you're talking about.

Privacy

CrushOn.ai

Your chats aren't encrypted. Simple as that. While you're sharing your thoughts and feelings with your AI girl, those messages could be collected and used to train their system.

The platform also shares your data with advertisers and vendors. You can't control this. You can't opt out. The only thing you can adjust is how the AI responds to you.

At least your bank statement shows "subscribestar.com" - so nobody will know you're having an AI affair.

Kupid AI

Your private chats aren't encrypted - at least Kupid AI never mentions it.

They store everything: your personal details, conversations, and usage data. And they keep it all for 6 years after you delete your account.

On your bank statement, the charge appears as “Kupid” — not exactly subtle.
