Secret Desires AI vs Joi Ai: Which One Is Better In 2025?

Secret Desires AI vs Joi Ai

I've spent a full week with both Secret Desires 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.

Secret Desires AI

An AI girlfriend platform that allows users to create customizable companions, generate images and live photos, and engage in fantasy scenarios, including intimate or adult themes.

Joi Ai

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

Character Diversity

Secret Desires AI

Secret Desires AI offers hundreds of characters across multiple ethnicities and personality types.

On top of the realistic options, it also offers a wide range of anime styles.

While the majority fall in the 18–30 bracket, there are some mature options as well.

However, body type diversity is limited — most characters are slim or athletic, with few alternatives.

The mobile app shines with precise filtering, letting you narrow searches by age, ethnicity, body type, personality, and relationship preferences.

On the other hand, desktop users get a more basic experience, with filters limited to style (realistic/anime), gender, and preset character tags.

But there’s a catch: filtering can be buggy — some tags return no results, and on desktop, you can’t combine multiple filters like you can on mobile.

At least the search bar helps get around some of the app’s heavier filtering limits.

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

Secret Desires AI

Character creation starts by selecting your character’s gender, style, and age.

Physical Customization:

• Ethnicity: 6 options (e.g., Caucasian, Asian, Indian)
• Appearance: Hairstyle, hair color, eye color
• Physique: Body type, breast size, butt size

Personality Customization:

• Personality: 12 options (e.g., dominant, seductive, unstable)
• Relationship Type: 25 options (e.g., wife, girlfriend, boss)
• Lifestyle: Work (36 options) and hobbies (21 options)
• Kinks: 15 options (e.g., vanilla, feet, edging)

The app also lets you add custom options for every category, so if you don’t find something to your taste, you can create your own.

You can select a voice from 12 options or upload your own audio.

As the final step, you’ll see a summary page to name your girl and bring her to life.

After the summary page, you’ll see a profile with an editable About Me, your chosen traits, and — if you’re lucky — with a character image, though it often fails and can’t be modified.

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

Secret Desires AI

When you select a girl to chat with, you can view her profile — including description, personality traits, and even personalize them to your taste.

The app also lets you set the chat engine from 13 different options to make responses more personalized, though this setting is somewhat hidden in your profile menu.

I chose a single mom character who showed genuine emotional range and stayed true to her persona.

My girlfriend moved naturally from playful flirting to handling deeper topics like jealousy with surprising depth.

My girl even referenced past conversations and wove them smoothly into ongoing chats.

But when I needed emotional support, her responses fit the situation perfectly.

As with the other features I tested, this one also comes with some technical hiccups.

Chat formatting is designed for mobile, leaving desktop with long, cramped text that’s harder to read

My girl often tried to send me images, but on the rare occasions I got any, it was usually just the text prompt of what should have been generated.

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

Secret Desires AI

My girl was open about past sexual experiences but shared only hints and details rather than full stories.

Think of her as reading a romance novel where she writes the next chapter based on your input.

In my tested roleplays, she stayed fully in character — confident, seductive, and with a solid build-up.

However, there’s a catch: after running multiple scenarios, my girl kept repeating the same lines and asking my name over and over again.

My girlfriend also refused explicit chat, even threatening to end the session.

Instead of explicit conversation, my girl could do surprising things — like solving mathematical problems if I asked.

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

Secret Desires AI

Secret Desires AI offers two ways to generate images:

• In-chat image generation: Quickly create images using free-text prompts.
• Dedicated Image Creator: A separate tool that gives you more control and customization

In-chat image works simply: Just type “send me” in chat, followed by the prompt for the image you want to see.

You can only generate SFW images — NSFW content isn’t allowed here.

Note: Works only with characters you created or those shared by other users.

Dedicated Image Creator lets you stay in control:

• Character selection for image generation
• Multiple engines to choose from: Monet, Picasso, DaVinci
• Number of images to generate: 1–64
• Free-text prompt option for maximum customization
• Default preset options: Action, Body, Clothing, Scene, Extras, with lots of presets.

Quality: At first glance, the images look good and could even pass for real photos, but on closer inspection, they’re pixelated.

Quirk: The images don’t match my girl’s main profile picture, and physical inconsistency is definitely an issue.

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

Secret Desires AI

Secret Desires AI turns static photos into videos, using settings almost identical to photo generation, with the added option to set video duration.

The good: These videos look natural. Your AI girlfriend's movements flow smoothly, and her personality stays consistent from photo to video.

Not so good: Video quality isn’t perfect — some pixelation is noticeable, though it’s minor enough not to disrupt the experience.

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

Secret Desires AI

Yes, the voices sound human enough, but every line feels like it’s being read off a teleprompter on fast-forward.

And if you’re hoping for emotional range? Forget it. Whether you’re flirting or just chatting, the delivery stays as flat as week-old soda

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

Secret Desires AI

The app claims your chats are "secure and confidential" - but never explains how.

There's no mention of encryption, and they're not clear about who can access your conversations or how long they keep them.

One clear promise: they won't sell your data to advertisers. But that's where the transparency ends.

During my testing, I couldn't find straight answers about data sharing with third parties like analytics providers or hosting services.

On your bank statement, it just shows as ‘Dover First SDA Hope Food Program Food Pantry’ — pretty 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.

Good news? Your credit card statement shows up as "edenai.world" - keeping your AI relationship discreet.
