Muah.ai vs Nomi AI: Which One Is Better 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, video, and voice interactions.

Nomi AI

A platform offering customizable AI girlfriends with emotional intelligence and memory, designed for authentic conversations and relationships through text or voice.

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.

Nomi AI

No pre-made personalities, no variety in ethnicity or age, and no anime — meaning there aren’t any ready-made characters to choose from.

You’ll need to create your own girls — you can have up to 10 in total.

Want more variety? The app lets you set up 10 group chats to mix these characters.

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.

Nomi AI

As you first log in to the app, you go through the onboarding process — you’ll be asked for your name, age, and gender.

Then, it’s time to set up your AI partner basics:

• Name, and gender: Male, female, or nonbinary.
• Relationship type: Choose what kind of bond you want — from romantic partner to mentor (four options).

Want something unique? Create a custom relationship and explain its background.

Personality Builder is where things get interesting — you can select 3 to 7 traits from several categories:

• Main Characteristics: modest, sarcastic, shy, flirty, etc.
• Expressive: sassy, witty, introverted, etc.
• Temperament & Values: arrogant, dominant, humble, etc.
• Additional: gamer, magical, spiritual, etc.

Then, you can (optionally) add a background story — write your own or let the AI create one for you.

Finally, it's time to choose your companion’s look — but this is where Nomi shows its limits.

You can choose from 500 preset images: 250 anime-style and 250 realistic, with only basic options for body types.

If you’re looking for detailed visual customization, you might find the options a bit limiting — because that’s all Nomi AI currently offers in terms of physical design.

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.

Nomi AI

Customization doesn’t end once you’ve built your Nomi — you can personalize her even more after the chat begins.

In "Backstory +", you can fine-tune even more — from their appearance and personality to how they perceive you.

Within the Mind Map — personalize her memory by adding notes on her interests, goals, and defining traits.

It’s organized into Lore, Topics, and Goals — a neat way to track your relationship’s growing history.

Want to know if Nomi AI's chat feels real? I created Natalie - bold, flirty, and playful - to test it for you.

Starting a chat is easy. Choose from fun, themed ice-breakers — each with three options, or just jump right in.

After I personalized a few things in chat, I can confidently say my girl remembered those settings and stayed consistent with her personality and the situation.

When I tried some jokes, my girlfriend recognized them and played along.

While my girl was engaged in many moments, her empathy sometimes felt a bit surface-level.

And occasionally, my girlfriend’d make odd jumps in conversation — like suggesting pizza right after we planned to cook together.

But the more you chat, the better Nomi knows you — the Mind Map evolves as it keeps track of everything you’ve shared.

Over time, my girlfriend started recalling moments from our past conversations — her replies became more relevant and felt real.

Note: Your Nomi’s memory and chat personalization can seem a bit overwhelming at first, but after a little practice, you’ll find it easy to use and customize.

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.

Nomi AI

My girlfriend smoothly shifted from casual flirting to explicit content, adjusting her language as the conversations intensified.

The responses feel organic rather than scripted, and as I shifted my tone to become more explicit, my girlfriend picked up on the language and responded naturally.

What surprised me most was how my girlfriend adjusted her overall approach based on my cues — whether I leaned toward slow-building romance or more direct encounters.

Role-play is where Nomi shows real potential. During testing, she didn't just follow scenarios - she created them.

After my girl settled the rules, she stayed true to the context and consistent with her character.

In one test, I tried to throw my girlfriend off her role, but she held her ground and kept the scene flowing naturally.

While my girlfriend’s “punishment” methods got a bit repetitive, she still kept the experience engaging overall.

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.

Nomi AI

Nomi AI offers two ways to generate images:

1. In-chat image generation: Quickly create images that try to fit the conversation
2. Dedicated Image Creator: A separate tool that gives you more control over image customization.

Dedicated Image Creator

• Choose an image style: anime or realistic.
• Write a free-text prompt describing what you want to see.
• Select an aspect ratio (three options available).
• Optionally, add a reference pose by uploading an image.

Quality: Nomi’s image generator delivers generally high-quality photos, though not in high resolution.

Image generation is slower than other platforms, sometimes taking a few minutes per image, but it’s also noticeably cheaper.

Note: NSFW prompts are not allowed. The spiciest results you can get in chat are mild and only appear when they fit the current topic.

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.

Nomi AI

Nomi’s video generator isn’t full video creation — it’s more like turning an image into a short animated clip.

Here's how it works:

• Choose an image to serve as the base.
• Provide a text prompt (make sure it follows the app’s content rules).
• Select the output quality (SD or HD).

The videos work - they're watchable and add more life to your interactions than static images.

But let's be honest: the quality isn't winning any awards. The footage comes out pixelated, and the character movements often feel mechanical rather than natural.

Note: NSFW generation isn’t available, and movement prompts feel a bit limited or don’t always apply to the final video.

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.

Nomi AI

Nomi AI offers four default voices to choose from, and you can upload your own custom voice to make your girl — and the overall experience — feel more personalized.

One big plus of Nomi AI’s voice feature is its ElevenLabs integration — enabling users to import and use ElevenLabs voices for greater variety, though it requires a paid plan.

Want to know how Nomi AI’s voice actually sounds? It works, but it’s a bit like a slightly robotic audiobook narrator — nothing that’ll make you go “wow.”

The voice does match Nomi’s personality, and she adjusts her tone a little when flirting or expressing emotions.

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.

Nomi AI

Their policy clearly states that your messages "may be unencrypted" - meaning someone could potentially read your private conversations.

Nomi AI stores everything. Your account details, chat history, and how you use the app - it's all saved on their servers.

They also share this information with other companies, though they don't specify which ones.

Your bank statement shows a ‘Nomi.ai’ charge — not exactly discreet.”
