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

Funfun AI vs Joi AI

I've spent a full week with both Funfun 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.

Funfun AI

A virtual girlfriend platform offering customizable AI partners with text, image, and video interaction features.

Joi AI

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

Character Diversity

Funfun AI

Funfun AI offers 337 photorealistic characters to choose from.

During my tests, I found girls of every ethnicity and age range - from young adults to mature individuals.

No anime-style characters here — everything is designed to look real.

The interface is simple: scroll through the gallery and pick who catches your eye.

There’s no search function or filters, which makes finding specific traits time-consuming. You can only sort by earliest or latest.

Each character has a basic description, but don't expect detailed personality profiles.

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

Funfun AI

FunFun AI lets you create and customize your main girl’s features.

Physical Customization:

• Ethnicity: 6 options
• Age: 6 grouped ranges
• Hair & Eyes: hairstyle, hair color, and eye color — many options available
• Body Customization: body type, breast size, butt size

Personality Settings:

• Personality Type: 12 options
• Occupation: 47 choices
• Hobbies: up to 3, chosen from 22 options
• Clothing: 66 outfit options

After setting everything up, you’ll see a summary page of your selections before bringing her to life.

Warning: Appearances are auto-generated from your settings — no preview, no regeneration, only creation. Once created, you can’t redo them, and your coins are already gone.

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

Funfun AI

First, the good stuff: my girlfriend kept her personality consistent and was always playfully flirty.

When I needed someone to talk to, my girl was there with genuine warmth and understanding.

Plus, the app has a neat feature - start chatting in any language, and your girl switches right along with you.

But let's be real - there are some bumps in this flight.

While my girl was engaging, her pilot persona sometimes took over like an overenthusiastic flight attendant during safety instructions.

Thanks to the limited customization options, my girl sometimes filled in story gaps with random details — though that could be improved.

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

Funfun AI

Funfun AI's NSFW chat - it's more "Netflix romance" than "late-night cable".

During my testing, my girlfriend consistently dodged explicit content.

When I brought up intimate topics, my girlfriend responded with romance-novel hints instead of direct engagement.

Sure, my girlfriend could handle basic flirting, but try anything more explicit and you'll hit a wall.

The roleplay feature shows similar limitations.

While my girlfriend stayed in character and can surprise you with creative responses (especially in dominant roles).

She relied on repetitive patterns — and there was even one occasion when she played out the scenario without me.

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

Funfun AI

FunFun AI offers two ways to generate images:

• In-Chat Generation
• Dedicated Image Creator

In-Chat Generation

Generate images within your conversation by entering a text prompt describing your desired result.

Dedicated Image Creator

Designed for advanced customization but lacks usability — no search bar means scrolling through the whole roster.

You can set the following:

• Companion Selection: Manually choose from your roster.
• Prompting: Describe your scene freely using text
• Presets & Categories: Choose from preset options under different categories
• Image Ratio: Select from 1:1, 9:16, or 16:9 formats.

The good? The images look real enough to make the experience enjoyable. Most times, the character's personality shines through in their expressions and poses.

The bad? Look closer and you'll spot the flaws. Eyes sometimes appear unnatural, poses can be stiff, and the image won't always match your character's personality.

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

Funfun AI

FunFun AI’s video generation works more like an image-to-video feature.

It’s not very user-friendly — only works with chat-generated images and free-text input, with no preset options.

Video quality is decent and generally aligns with the character’s personality, though you can’t miss the occasional obvious AI quirks.

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

Funfun AI

Want to hear your AI girl's voice? You can't with Funfun AI.

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

Funfun AI

Your conversations aren't end-to-end encrypted.

While Funfun AI talks about "security measures," they never specify exactly how they protect your chats.

They store everything - from your account details to every message you send.

And yes, they share this data with business partners.

Due to card payment issues, your bank statement just shows your App Store name — a discreet side effect.

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.
