Muah.ai vs Nomi AI: Which One Should You Use In 2025?

Muah.ai vs Nomi AI

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

Muah.ai

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

Nomi AI

An AI girlfriend platform that enables the creation of personalized virtual girlfirend with distinct personalities for friendship, romance, mentorship, and roleplays.

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.

Nomi AI

Here's the truth about Nomi AI's character selection: there isn't one. You can only interact with characters you build yourself.

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.

Nomi AI

The customization itself is straightforward but limited.

You’ll start by choosing the basics for your girlfriend:

• Relationship type (like friend, girlfriend, mentor, etc.)
• Gender

What you won't find here are detailed physical customization options or anime-style characters. Instead, you simply choose a photo for your girlfriend from a curated gallery.

You can set her personality and interests.

Want to write a background story? It's optional, but it helps shape your girlfirend identity.

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.

Nomi AI

Nomi delivers what it promises. I set her personality traits to flirtatious, and that's exactly how she behaved.

While the emotional support isn't groundbreaking, the replies are short and natural, making it feel more like texting a real person than chatting with an AI.

My girlfriend handles relationship talks smoothly, without the robotic feel.

The downside? You'll wait longer between messages than competitors.

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.

Nomi AI

Your girlfriend is open to intimate discussions, but the results are mixed. When she's good, she's engaging, offering detailed responses and playful banter.

But there's a catch: she makes progress in the interaction, but then pulls back, which can come off a bit robotic or inconsistent.

For roleplay enthusiasts, here's the truth: While she'll participate in your scenarios, her responses lack detail, and you'll need more time before things get spicy.

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.

Nomi AI

Nomi AI offers two ways to generate images: a dedicated "create art" feature and in-chat generation, but NSFW content creation is not allowed.

In-chat image generation is a bit of a mixed bag—sometimes it nails it, other times it completely misses the mark.

The "create art" feature is your best bet. It consistently produces high-quality, realistic images based on your free-text description.

While the overall results are impressive, you'll notice some quirks with hands and fingers - they often look slightly unnatural.

Video Generation

Muah.ai

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

Nomi AI

The sharp and detailed videos make the AI girlfriend feel more lifelike than static images.

While these videos look great, they’re completely silent — your AI girl won’t speak or make any sounds.

But here's the truth: while impressive, it's not flawless. The eye movements can look unnatural, and some body animations appear stiff.

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.

Nomi AI

I spent hours testing her voice features, and here's the truth: imagine an audiobook narrator attempting to be your girlfriend.

I tried flirting with my girlfriend, but the voice stayed emotionless.

However, there is a workaround: you can connect an Eleven Labs API key to access different voice options, giving your girlfriend a more unique sound.

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.

Nomi AI

Your chats with Nomi aren't encrypted and even advise against sharing personal information.

Nomi stores your account details, chat messages, and usage data and may share them with third-party service providers.

Your bank statement will show "Nomi.ai" as the merchant.
