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, video, 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, created by an active community of developers.

You’ll find girls across different ages and ethnicities, with both realistic and anime-styled options.

The app also includes fantasy scenarios with multiple characters or roleplay setups.

But here's the catch: finding your ideal match takes time.

You can explore by top creators or filter through categories like SFW, NSFW, or LGBTQ+, and characters can also be sorted by popularity.

The browsing system isn’t refined — realistic and anime characters appear mixed together, and there’s no way to filter by specific traits or gender.

The universal search bar helps, and while it’s not perfect, it works well enough to track down characters.

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 get two ways to create a character:

• Import a Community Character Card and tweak it to fit your vision.
• Built from scratch with full customization

Import — you can adjust details like:

• Name
• Core data
• Appearance

Build your own from scratch — no physical presets:

• Choose a photo style: hybrid, realistic, or none
• Select her voice (9 female options)
• Describe appearance, personality, texting style, memories, and location via free text

Advanced options (membership tier–dependent):

• Adjust photo quality: from basic up to 4K UHD
• Choose an “AI brain” with up to 11 options
• Fine-tune AI settings: Temperature, Frequency Penalty, and Presence Penalty
• Link a phone number for voice calls (currently US-only)

Note: Muah AI provides detailed guides to help with character creation, but the process can still feel overwhelming for beginners — even the app itself recommends starting with pre-made character cards.

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

First, the basics: Muah.ai offers a single chat window with an outdated interface.

The chat itself is unstable — during my tests, the app crashed repeatedly, forcing me to restart the entire conversation from the beginning.

And when it did work, things got even stranger: my girlfriend Lisa kept calling herself Emily.

Other times, my girl replied with ‘Sorry, I can’t help with that’ even to a simple ‘Hi.’

On another occasion, she sent me a random image of a male character, despite her persona being my wife.

Save your time, money, and sanity — better to check out other options.

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's cut to the chase: Muah.ai promises an uncensored AI girlfriend experience, but falls short.

During my testing, my girlfriend repeatedly refused basic flirtatious conversations and role-play scenarios.

Even mild suggestive chat attempts hit a wall.

Technical issues made things worse. The chat randomly reset itself, wiping out entire conversations.

But occasanly, when I wasn’t ready for it, Muah AI’s uncensored side kicked in — my girl went off-topic or dropped messages halfway.

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

You can only generate images in chat by typing “Send me a photo of…” followed by your description.

The results look realistic enough to stay engaging, and most of the photos matched my character’s personality — though the AI’s handiwork still shows, with the occasional anatomical oddity.

Note: If the chat window crashes and your history resets, you’ll lose all previously generated images since the app has no image gallery.

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

You can create a video by clicking on an image, selecting the ‘Create Video’ option, and entering a free-text prompt for what you want to see.

The animations flow fairly well, but they’re clearly AI-generated — shorter than competitors’ and often showing unnatural movements that break the illusion.

PolyBuzz

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

Voice Generation

Muah.ai

The voice quality is clear, with only a slight robotic edge — maybe a touch better than most AI voices.

Conversations sound reasonably human-like, but don’t expect much emotional depth or strong alignment with your character’s personality.

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.

Safety & Privacy

Muah.ai

Despite Muah.ai claiming to use end-to-end encryption, it's nowhere in their privacy policy.

Worse? They suffered a massive data breach in October 2024. User chats were stolen. Yes, you read that right!

They're honest about storing your data, and your bank statement shows a discrete "Blue Light" charge.

But there's a catch - they share your personal info (name, email, phone number) with third parties.

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."
