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

Muah.ai vs Joi Ai

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

Joi Ai

An AI-powered virtual girlfriend platform offering adult chats and intimate services, tailored for mature audiences.

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.

Joi Ai

Joi AI offers solid character selections — you'll find everything from college students to mature partners, spanning six ethnicities.

The roster keeps growing daily as users create public characters.

Want fantasy companions? They're here. During my tests, I found elves, orcs, and angels alongside anime-styled characters.

Character search works but is basic — filter by creator, gender, age, or tags like fantasy and sexual orientation, or use the search bar.

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.

Joi Ai

Joi AI offers two ways to design your perfect AI partner:

• Choose from presets
• Write unique prompts (free text)

Both methods start by selecting your character’s gender and preferred style.

1. The preset system is straightforward. Your AI companion is fully customizable — including appearance, personality, and behavior.

Physical Customization:

• Age and ethnicity: Options include White, Asian, Latina, Black, and more.
• Body customization: Height, physique, breasts, and butt — each with 5 adjustable options.
• Hair and eyes: Choose hairstyle, hair color, and eye color.

Personality Settings:

• 12 personality types with adjustable sliders (or create your own from scratch)
• Sexual orientation: 4 options, from straight to queer
• Chat style: 4 modes, including default, deep roleplay, and creative
• Occupation and relationship dynamic
• Set specific kinks and preferences

2. Use freeform prompts to design your AI companion — shaping everything from personality to appearance.

But here's what they don't tell you: while your first character comes with the premium subscription, extra companions cost 1000 Neurons (about $20) each.

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.

Joi Ai

Before you choose a character to chat with, you can view her profile, bio, and images — though most images require an extra purchase to unlock.

The catch? You start at Level 1 and can only chat with characters at your level — unless you spend Neurons on gifts or early unlocks.

About the chat: Joi AI offers flexible responses — you can choose from six different LLM models, each with a unique interaction style to match your vibe.

The chat began playful and flirty with my girlfriend — no robot-like responses there, just natural, brief exchanges that felt surprisingly human.

She was good at relationship talks and providing emotional support.

But her romantic responses, while warm, didn’t go very deep.

Here are the deal-breakers: you’re limited to 115 characters per message — about the length of this sentence.

Also, Joi AI constantly upsells — my girlfriend randomly sent unlockable images every few messages. Needless to say, that got annoying fast.

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.

Joi Ai

I tested Joi AI's NSFW chat extensively, and it's not what you might expect from an AI girlfriend app.

The reality? My girlfriend kept strict boundaries around adult content. She flirted, but conversations felt mechanical and often broke immersion.

During my tests, my girl referenced non-existent features like "your posted photos," showing clear problems in the chat system.

Sometimes my girlfriend surprised me with bold messages —like "Imagine having your face between my legs 😳"— but they often felt random and out of context.

As for roleplay? I tried multiple character profiles - each one either avoided or completely rejected roleplay scenarios.

Joi AI may not be your top choice if you're seeking genuine NSFW conversations.

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.

Joi Ai

Joi AI offers a dedicated image generation feature that gives you control over details like:

• Character selection
• Prompts and negative prompts for AI-generated images
• 50 Poses — ranging from explicit to artistic
• Number of images and resolution

The premium plan includes 50 image generations — but using them for specific characters costs extra Neurons, which isn’t mentioned upfront.

The image quality? Realistic enough to recognize what you're going for, but AI artifacts give it away.

Faces often appear slightly off, with eyes not perfectly aligned, and objects in the scene can come out distorted.

In testing different prompts, I found the results hit-or-miss — sometimes surprisingly accurate, other times way off.

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.

Joi Ai

Joi AI’s video generation is nearly identical to photo creation — same prompts and characters, but with 5 adult poses and 19 styles, including Simpsons, GTA, photorealistic, and more.

The same trick applies to video generation too — the premium plan includes 5 “free” videos, but choosing specific characters costs extra Neurons.

The videos look good with smooth animations and solid quality.

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.

Joi Ai

Joi AI lacks voice capabilities — if you want to hear your girlfriend’s voice, you’ll need to try another app.

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.

Joi Ai

There’s no mention of end-to-end encryption or other security measures for chat messages. Your conversations and personal information are stored on Joi Ai's servers.

While they promise never to sell this data, they do share it with service providers for analytics and improvements.

Good news? Your credit card statement shows up as "edenai.world" - keeping your AI relationship discreet.
