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

Nomi AI vs Fantasy AI

I've spent a full week with both Nomi AI and Fantasy 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.

Nomi AI

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

Fantasy AI

A platform for creating highly realistic AI girlfriends, offering lifelike avatars, adaptive conversations, and immersive image artwork.

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.

Fantasy AI

Fantasy AI offers 199 characters to chat with, but the selection only includes realistic female characters — no anime or male options.

You'll find women of different ages (18+ to mature), six ethnic backgrounds, and varying body types.

Character search and filters work like this:

• You can sort by likes or views, and check out the latest additions
• Filter by basic traits like age, body type, and hair color.

The app also includes AI versions of real models and OF creators as "verified profiles."

Keep in mind that these premium characters cost extra tokens to chat with.

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.

Fantasy AI

App creation starts with choosing a style for your girlfriend — real or anime.

The following customization process is straightforward. You pick basic features:

• Ethnicity (6 options)
• Age group and face style
• Body type and boobs
• Har color and style
• Outfit from casual to professional (19 options)

The app also lets you choose from 16 voice options.

Personality customization isn’t very deep. You can only set your character with 11 options — a simple mix of personality and relationship type.

And finally, you get a summary page of your character.

The drawback: The app generates an image based on your settings for your girl — and whether you like it or not, you’re locked in with it.

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.

Fantasy AI

Fantasy AI's chat interface works like your everyday messaging app. Clean bubbles, quick responses, no learning curve.

When I first started chatting, my AI girlfriend brought energy and playfulness to the table.

To be real: Our chat was playful and flirty, but shallow, my girl rarely asked any follow-up questions about me.

When I mentioned having a rough day at work, my girl acknowledged it with a quick "Aww, sorry to hear that," but didn't offer real support or try to understand why.

Want romance? My girlfriend played along, but don't expect Shakespeare.

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.

Fantasy AI

The good news: my girl kept it spicy and was open about her sexuality.

My girlfriend maintained character, built tension naturally, and kept conversations flowing with suggestive hints rather than crude explicitness.

Whether I was into light flirting or deeper roleplay, my girl adapted and stayed convincingly in character.

Heads up: Expect sales interruptions. Right when things got interesting, my girlfriend likely tried to sell you ‘unlockable’ images.

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.

Fantasy AI

You’ve got two options for generating images:

1. Dedicated Image Creator
2. In-chat Generation

Dedicated Image Creator

A separate tool with more customization and control.

• First, you choose the image type: realistic, anime, or fantasy.
• Then, you pick from 24 preset options (many of them adult themes).
• No custom character images or free-text prompts — only presets are available.

In-chat generation

Quick image right there in chat.

• Send “Show me…” commands with your prompts.
• Characters may sometimes refuse or miss the mark.

You can generate character-specific pictures through their profile page by choosing from preset outfits.

The good: Images often look realistic and detailed.

The not-so-good: The quality is pretty inconsistent, physical features often change from one generation to the next, and prompts rarely deliver.

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.

Fantasy AI

Fantasy AI doesn’t actually generate videos — instead, it gives you access to a content gallery.

The gallery contains clips of girls — some locked, some unlockable — though it’s uncertain if the videos are truly AI-generated.

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.

Fantasy AI

My AI girl whispered and stuttered through normal chats, which felt odd.

During flirty moments, her tone shifted to match the mood, but the quality wasn’t the best.

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.”

Fantasy AI

While they store your chats on secure servers, they don't mention encryption anywhere in their privacy policy.

They share your data with companies like DigitalOcean for hosting, but your data still travels beyond Fantasy AI's walls.

In your bank statement, you’ll see "fantasy ai"—which isn’t very discreet
