Muah.ai vs PolyBuzz: Which One Is Better In 2025?

Muah.ai vs PolyBuzz

I've spent a full week with both Muah.ai and PolyBuzz 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.

Muah.ai

Virtual companion platform featuring customizable AI characters that allow for chat, photo sharing, and voice interactions.

PolyBuzz

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

Character Diversity

Muah.ai

Muah.ai offers thousands of characters to choose from. Their community-driven platform means new characters are added regularly, giving you plenty of options to explore.

The diversity is practical and straightforward. You'll find characters across all ethnicities and age ranges. I tested the search function by typing "teacher" - it returned both realistic and anime-style characters that matched my query.

While there's no filter system, you can browse characters by popularity metrics like views, likes, or comments. Whether you prefer casual chats with a student character or deep conversations with a mature companion, you'll likely find what you're looking for.

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.

Customization

Muah.ai

You start by picking a basic role - girlfriend, friend, therapist, or several others. Then comes the real customization: choose how they look (anime, realistic, or hybrid), how they sound, and even how they text.

It's all done through simple text commands - just describe what you want, and the AI adapts.

Want your companion to remember specific moments with you? You can create shared memories and even set up custom scenarios for your conversations.

While these options give you complete control, they might feel overwhelming at first. If that's the case, Muah.ai's marketplace offers pre-made companions you can start with.

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.

Chat Experience

Muah.ai

The good? Your AI girlfriend stays remarkably true to character. Set them up as a coworker, and they'll keep things professional even if you flirt.

They'll remember specific memories you create together (in my case, it was that time watching fireworks in Japan) and can smoothly set up immersive scenarios - like suggesting coffee and continuing the conversation as if you're actually at the café.

The not-so-good? Memory issues kill the experience. One minute, you're deep in conversation; the next, they'll greet you like a stranger. It looks like AI only remembers 10 messages, and if you want more, you'll have to pay for the most expensive plan.

The interface looks dated, and you're stuck with one chat window. Want to try a different character? You'll need to delete your entire conversation history first.

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.

NSFW Chat Experience

Muah.ai

Let me tell you, these AI girls don't hold back. They flirt, they play along, and they're ready to explore your fantasies. Unlike most AI girlfriends that dodge steamy topics, Muah.ai's characters dive right in.

I tested everything from casual flirting to complex role-play scenarios - the AI kept up without breaking character.

But here's the catch: the same memory issue applies to NSFW chatting. While the chat feels natural in the moment, the AI often forgets what you discussed 10 messages ago.

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.

Image Generation

Muah.ai

The images are realistic enough to be engaging, but don't expect perfection. You'll get appealing photos that capture your girl's personality well, maintaining consistent features across most shots.

Sometimes, you'll spot oddities - misaligned eyes or the occasional extra limb - but these flaws rarely break the experience.

While default images come in standard quality, you can upgrade individual shots to 4K.

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.

Video Generation

Muah.ai

Want video interactions with your AI girlfriend? Then you'll have to look for an alternative.

PolyBuzz

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

Voice Generation

Muah.ai

The voice quality is clear and doesn't sound like a robot. During conversations, the AI speaks naturally, but there's a catch: while the AI can change its tone, it can't express emotions.

But here's what annoyed me: the narrator and your AI girl share the exact same voice.

For US phone numbers, there's also a phone call feature that lets your AI girl ring you up, but you'll have to subscribe to the most expensive plan.

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.

Privacy

Muah.ai

Your conversations aren't as private as you might think. Yes, they say they use end-to-end encryption. Strangely, this isn't mentioned anywhere in their privacy policy.

The biggest red flag? In October 2024, Muah.ai suffered a major data breach. User chats were stolen. That's not just a minor hiccup - it's a serious privacy failure.

The one bright spot? Your credit card statement will simply show "Usweixin Cardshop AI" - keeping your AI relationship private from prying eyes.

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."
