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

Muah.ai vs Yodayo

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

Yodayo

An AI-powered platform that converts text prompts into anime-style artwork, offering character customization, community sharing features, and interactive character chat capabilities for anime enthusiasts.

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.

Yodayo

Yodayo offers thousands of characters to choose from.

Most are anime-style or fantasy-based, with a smaller selection of realistic characters available.

I found everything from traditional anime personalities to fantasy creatures like orcs and cyborgs.

The search system is practical. You can filter characters:

• Filter by traits or categories
• Browse: Popular, Trending, New, etc.
• Search using keywords.

This helps narrow down options quickly, though the process could be overwhelming for first-time users due to the sheer number of choices.

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.

Yodayo

First, let's address the elephant in the room: Yodayo doesn't offer physical appearance settings. Instead, it focuses entirely on personality and interaction — you can only upload an image of your character.

You get two creation paths:

• Quick AI-assisted setup through YoPilot,
• Detailed manual customization.

Manual mode gives you more control - you write the character:

• Description
• Persona
• First message
• Scenario

Pilot keeps it simple: type in a name, description, and gender, and the AI does the heavy lifting.

You can choose voice presets (including celebrity voices) or upload your recordings.

The platform features hashtags and a tagging system that helps categorize your character.

The real customization happens in the advanced settings:

• Different LLM models
• System preset (such as roleplay, spicy roleplay, humor, etc.)
• Model parameters.

You can also customize image generation with many fine-tuning and preset options.

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.

Yodayo

The platform lets you pick from multiple AI models - from free options to premium ones like GPT-4 and Claude.

I tested Nephra 12b (a free model) and found the conversations flow naturally, without the robotic feel you might expect.

The flirtation level adjusts based on your interaction style, though it can sometimes get quite forward.

During testing, my girl handled both light chats and deeper conversations well, showing solid emotional awareness and offering comfort when needed.

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.

Yodayo

My girlfriend handled sexual topics with surprising authenticity. She maintained her character and adapted to different scenarios without breaking immersion.

The role-play experience is solid. My girl stayed in character and followed conversation threads naturally, whether you're keeping things light and flirty or exploring deeper fantasies.

But she's not perfect - sometimes her responses can feel repetitive during longer sessions.

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.

Yodayo

Yodayo offers two ways to do it.

The In-chat image generation- ask for a picture, and a settings window will appear:

• What to generate (yourself, your face, or the last message)
• A custom prompt using free text
• The image engine and fine-tuning settings
• Canvas size, and more

The result? You'll get natural-looking photos that match your character, but occasional inconsistencies.

One limitation is that changing the pre-generated prompts can be difficult for new users and may lead to unwanted results.

The separate image tool offers more control, with detailed prompt explanations and precise settings.

While powerful, it comes with a catch: you can't generate images of your specific AI companion here. You'll need to use the in-chat generator for that.

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.

Yodayo

The app doesn't generate videos. Period. If you're after a more lifelike experience with video features, you'll need to 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.

Yodayo

The voice sounds robotic and flat - imagine Siri from 2011, not a modern AI girlfriend.

During my testing, even flirty conversations felt mechanical, with only slight tone variations that barely register.

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.

Yodayo

Your messages are locked down with bank-grade encryption. This means nobody, not even Yodayo's team, can peek at your private conversations.

But here's what you should know: Yodayo keeps your messages and shares some data with companies like Google Analytics.

When you check your bank statement, you'll see "Moescape AI" which apparently is new brand name for Yodayo. But what it meas for you? It means you can forget about the discretion.
