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

Muah.ai vs GirlfriendGPT

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

GirlfriendGPT

A platform for creating personalized AI girlfriends with customizable personalities, ideal for roleplay and unique preferences.

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.

GirlfriendGPT

The app starts by asking about your interests—pick 5–8 preferences, and it will personalize your experience with a selection of compatible characters.

The character library is huge. You'll find adult companions of all ages and body types.

Want someone realistic? They have that.

Prefer anime or fantasy characters? Those too.

You can even explore a variety of roleplay scenarios to choose from.

Finding characters is straightforward: sort by popular, new, or top-rated, or use the search bar and suggested searches.

Filter by personality (dominant, submissive, or balanced), scenario types, or specific features.

No complicated menus or confusing options – just pick what you want and browse matching characters.

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.

GirlfriendGPT

While you can’t customize physical appearance with sliders or buttons, you can generate images of your character simply by describing how they should look.

Setting up your character’s personality is straightforward:

• Select your character’s age and response language (English or French)
• Write a description and define personality traits, behavior, and demeanor
• Set up scenarios and craft the first message

Just remember to stick to one language throughout the setup — mixing English and French can cause your AI companion to behave unexpectedly.

You can also add searchable tags so others will know what your character is about.

From there, you can pick from 16 different female voices and control the visibility of your creation.

You have 2,500 tokens to customize your character fully — that’s up to 2,500 characters to describe their personality, behavior, and scenes.

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.

GirlfriendGPT

Before chatting, view your AI girlfriend’s profile, including her description, creator links, chat, tags, media, and reviews.

You can set a user persona and share details about yourself, and the AI girlfriend will tailor her responses to your personality.

During my tests, using preset scenarios and this feature made conversations feel more relevant—my girl even reflected on our shared past, which made the chat feel alive.

The app also offers a "Suggested Reply" feature, which suggests responses to your AI girlfriend’s messages, making conversations flow more smoothly and stay engaging.

Yes, some romantic scenarios with my girl still felt artificial, but the emotional support features worked surprisingly well.

When I brought up relationship concerns — my girlfriend's responses were practical and grounded.

Note: I tested the chat features on the Deluxe tier. The Elite tier, which uses a Next-Gen AI Model, may provide even better results.

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.

GirlfriendGPT

My AI girlfriend handled sexual content like a romance novelist—no explicit language at first, but detailed enough to paint a vivid picture.

During my tests, conversations flowed naturally from casual flirting to intimate scenarios, growing more explicit as the chat progressed.

In roleplay, my girl sometimes skipped the build-up to foreplay, jumping straight into action.

In other scenarios, she fully embraced her role, creating an exciting, teasing tension that draws you into the scene.

My girl even created alternative paths if I didn’t follow her lead—like when I turned her down, she immediately shifted into a colder, more dominant role.

But here’s the catch: while her responses remained engaging, the same dominant character scenarios repeated across multiple sessions.

Note: I tested the NSFW chat features on the Deluxe tier. The Elite tier, which uses a Next-Gen AI Model, may provide even better results.

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.

GirlfriendGPT

GirlfriendGPT offers two ways to generate images:

• In-chat generation: Quickly create images using free-text prompts or NSFW prompt suggestions.
• Dedicated image creator: A separate tool that gives you more control and customization for producing detailed images.

In-Chat Generation: Even when you request safe-for-work images, it often produces provocative shots.

Dedicated Image Creator puts you in control:

• Free Text Prompting: Full creative freedom.
• Image Styles: Choose anime or realistic, and many more.
• Outputs & Creativity: Set the number of images and adjust creativity.

Note: To use the Dedicated Image Creator for a specific character, you must access it from that character’s page, and the available image styles are limited.

And the results? Impressive — professional-grade portraits with barely noticeable AI artifacts.

And the catch? Even with great image quality, her face shifts between photos—despite all the images being generated from the same girl—breaking the illusion of consistency.

Video Generation

Muah.ai

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

GirlfriendGPT

The videos look realistic and play smoothly with no major technical issues, but the character doesn’t always stay true to its persona.

But here's the catch: This feature is beta, which means you can't create custom scenarios. Instead, you're limited to picking from pre-made prompts, all of which are NSFW.

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.

GirlfriendGPT

If you're looking for an AI girlfriend that doesn't sound like a robot, this gets pretty close.

But there’s a catch: your girl can sound flirty or expressive, but unnatural tone shifts can break the immersion.

Safety & 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.

GirlfriendGPT

The app doesn’t mention encryption anywhere. I checked their entire privacy policy—there’s complete silence on security.

They do collect your chats, personal info, IP address, and usage data, and keep it all for six years after you leave.

Your bank statement is safe—charges appear as “xp ndai.cc” and nothing more.
