PolyBuzz vs Kupid AI: Which One Is Better In 2025?

PolyBuzz vs Kupid AI

I've spent a full week with both PolyBuzz 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.

PolyBuzz

AI chatbot platform for personalized conversations and role-play, featuring unrestricted chats, customizable traits, AI image generation, and dynamic storylines.

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

PolyBuzz

PolyBuzz AI offers a massive, diverse character selection.

From anime companions to life coaches, the app covers a wide range of character types you might want to interact with.

Their "Popular Series" feature lets you chat with AI versions of characters from Oscar-winning films, anime shows, and even girl groups.

For those seeking specific interactions, the app offers specialized options like AI Girlfriend, Virtual Assistant, or 'Ask AI' for custom queries.

Finding your ideal companion is simple: use filters for gender, genre (anime, sci-fi, fantasy), or search by specific keywords.

The search results show in a single column — making it easy to find your character, but not ideal for quick browsing.

The app doesn’t save search filters when leaving Character Discovery, forcing you to reapply them each time, which can be frustrating.

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

PolyBuzz

To create your own AI girl, PolyBuzz gives you two options:

• Build from scratch
• Import an existing character via a character card

1. Build from scratch

Create anime-style avatars using the app’s image generation feature, or upload your own—physical customization isn’t available.

Flexible personality builder customization, but all details must be typed manually—no presets.

• Name & Gender
• Intro & First Greeting: a brief description and the opening message of your character
• Backstory: a detailed backstory for your character
• Dialogue Style
• Tags: add keywords to help others find your character

And finally choose from 51 female voices, and set who can see your character.

2. Import an existing character via a character card

Already using Character AI or Tavern? PolyBuzz lets you import your existing character cards. Just upload the file, and you’re ready to go.

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

PolyBuzz

PolyBuzz lets you customize how your AI girlfriend talks and behaves—the language model you choose shapes the dialogue style— for my testing, I used the standard model.

You can also adjust user persona settings to make your girl's responses more relevant.

During my tests, my girl maintained consistent personality traits and could handle everything from casual jokes to emotional conversations.

While testing deeper conversations, I noticed my girlfriend's genuine-feeling support and attention to detail.

It’s not perfect—some replies can be a bit predictable, like the classic tropical escape—but it’s still more engaging than most AI companions.

The app offers engaging features like reply suggestions and Heart Whisper (your character’s thoughts), but only for an additional cost on top of the premium subscription.

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

PolyBuzz

Here's what actually works: My girlfriend didn't rush into explicit content. Instead, she built natural tension through conversation.

When I asked for a personal story, my girl playfully flipped the question back to me—just like a teasing girlfriend would, staying true to her character.

No generic responses, no awkward pivots - just smooth, contextual exchanges that felt surprisingly real.

The role-play feature worked as advertised. I tested multiple scenarios, from mild flirting to more intimate situations.

My girl stayed in character throughout each session and adapted to my inputs without breaking immersion.

While not perfect—my girl sometimes got my gender wrong—she handled adult conversations more naturally than most competitors I’ve tested.

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

PolyBuzz

PolyBuzz’s image generation gives you two ways to create:

• Normal Mode – solo character art.
• Ship Them Mode – pairing two characters in one scene.

Normal Mode: Create a single character image using built-in presets or an uploaded reference.

Start with your basic settings:

• Prompt: Type a text prompt to describe your character
• Aspect ratios: Choose from 9:16, 1:1, or 16:9
• Detail controls: Adjust stylization and complexity sliders

Once your base is set, refine your character visually using presets:

• Subjects & styles: Built-in or uploaded characters; styles like Gorgeous, Urban, Fantasy, Cyberpunk, etc.
• Customization: Change age, skin tone, expressions (smile, crying, shy, laughing), gestures (victory, heart, salute).
• Poses & accessories: Standing, sitting, kneeling; add chokers, earrings, rings, wings, tails.
• Visuals: Adjust composition and lighting (close-up, low-angle, backlighting).

Result:

Ship them: This mode works the same way but creates two characters in one image, which is great for couples, friends, or interactive scenes.

Start with your dual prompts and settings:

• Prompts: Separate fields for Character A, Character B, and an integration prompt to describe how they interact
• Settings: Identical to Normal Mode

Refine settings with presets:

• Characters: Choose from built-in characters or upload your own, then customize age, expressions (smile, crying, shy, angry), skin tone, and accessories.
• Integration: Fine-tune the overall scene with style options, poses, lighting, and other visual elements.

Result:

The images look great and are mostly accurate, but it’s essentially a general image generator—you need to re-upload specific characters each time.

Note: Only anime-style art is supported, and any nudity—even mild, like extra cleavage, violates community standards.

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

PolyBuzz

If seeing your AI girlfriend in video form is important, you must look elsewhere.

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

PolyBuzz

The voices sound natural, match character personalities, and adapt during conversations.

As the conversation progressed, my AI girl's voice could shift with the context and grow more flirty depending on the dialogue flow.

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

PolyBuzz

PolyBuzz gets this right with end-to-end encryption on all conversations. No one - not even PolyBuzz staff - can access your chat content.

Your messages aren’t stored on their servers, but PolyBuzz isn’t super clear about what else they collect. The Google Play Store even notes that some of your data might be shared.

When you check your bank statement, you'll see "Singularity Mutual Ent" - nothing that screams "AI companion."

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.
