Nomi AI vs Yodayo: Which One Is Better In 2025?

Nomi AI vs Yodayo

I've spent a full week with both Nomi 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.

Nomi AI

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

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

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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

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.”

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.
