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

Fantasy AI vs Joi AI

I've spent a full week with both Fantasy 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.

Fantasy AI

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

Joi AI

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

Character Diversity

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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

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

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.

Even your credit card statement shows up as "joi.com" - which is not discreet at all.
