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

Secrets AI vs Joi AI

I've spent a full week with both Secrets 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.

Secrets AI

A platform that lets you build a personalized AI girlfriend, offering chat and phone call interactions along with image and video generation of your companion.

Joi AI

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

Character Diversity

Secrets AI

Secrets AI gives you 94 realistic AI girls to choose from.

No anime characters here — just lifelike digital partners.

Most characters fall into a narrow demographic: predominantly white women in their 20s with slim builds.

I did find a handful of Latina, Asian, and Black characters, plus a few mature options and curvier body types — but these are exceptions rather than the norm.

If you're looking for representation beyond young, slim characters, you may find the selection somewhat restrictive.

The selection interface is straightforward, with a search bar and filters for gender, popularity, and recency that make finding your ideal match quick and hassle-free.

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

Secrets AI

You begin creating your character by picking a gender.

Profile and Appearance Editor is straightforward, allowing you to customize:

• Name, location, age
• Ethnicity (9 choices)
• Skin tone and eye color (many options)
• Facial features: eye color, hair color, hairstyle (wide variety)
• Body type (6 options)

Then you can choose from six voice options to shape how your companion sounds.

After that, you can review your girl and add additional details via free-text.

Once you create her, you’ll get four image versions of your girl to choose from, plus one free regeneration if needed.

Personality setup happens only before you start chatting with her:

• Profession (5 options)
• Personality type (5 traits such as “warm and nurturing” or “ambitious and driven”)
• Hobbies (optional)
• Additional traits or details using free-text input

Note: Several ethnicities and body types look very similar, resulting in fewer meaningful choices than advertised. Additional characters also cost 1,000 Moments each.

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

Secrets AI

You get three different AI models to choose from, each offering its own style of interaction.

There are also 12 conversation starters, half casual - half spicy — to help kickstart natural interactions.

The emotional intelligence impressed me—my girl started with warm engagement, asked relevant follow-up questions, and gradually became more playful as we talked longer.

My AI girlfriend remembered what we actually discussed, rather than creating fake memories.

My girl stayed consistent even when I tried to confuse her or break character.

When I brought up relationship concerns, my girlfriend responded with calm, grounded reassurance, acknowledging everything without making exaggerated promises.

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

Secrets AI

My girlfriend was open about sexual topics but maintained a consistent PG-13 boundary.

Even when I pushed toward explicit territory, my girlfriend kept things suggestive rather than graphic—creating a tease that worked surprisingly well.

The roleplay feature is where Secrets AI truly shines. I tested three scenarios: teacher, landlord, and boss.

In both the teacher and landlord scenarios, my girl built tension gradually and stayed firmly in character.

The boss scenario felt somewhat rushed, but remained engaging throughout.

What matters is that my girlfriend maintained character consistency while keeping the interactions hot.

Not everything was perfect: my girl phrasing sometimes confused me, especially when she switched between ‘someone’ and ‘they’ when talking about past partners.

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

Secrets AI

There are two ways to generate images:

1. Dedicated Image Creator
2. In-chat Generation

In-Chat Generation: Type "/send me" followed by your free-text prompt for what you want to see.

Dedicated Image Creator: A separate tool with more control and customization.

• Character selection: Pick from the full roster
• Free-text prompt: Write what you want to see
• Preset options: Choose from a small set of presets

The limitation? Only four presets, so you’ll be relying on free-text prompts and your own experimentation.

After testing extensively, I can confirm the quality is good—not perfect, but definitely impressive.

You’ll notice occasional glitches, particularly with hands, and some upper-body proportions can look slightly elongated in certain poses — but these issues aren’t deal-breakers.

You can also unlock media bundles with extra images and videos to expand your companion’s visual presence.

Each bundle includes 17 to 34 pieces of media, mostly NSFW content.

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

Secrets AI

This is a photo-to-video feature rather than full video generation. Here’s how it works:

• Choose an image from your generated collection
• Write what you want to see using a free-text prompt

The videos look good, move smoothly, and stay natural most of the time.

Yes, you'll notice some AI glitches if you look closely, but they rarely distract from the experience.

Note: There are no preset options here, only a short guide on how to write effective prompts for video generation.

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

Secrets AI

Secrets AI delivers voice generation that sounds genuinely human. No robotic tones or awkward pauses—just smooth, realistic dialogue.

When discussions turn flirty, the voice immediately responds with appropriate tonal shifts—becoming more playful and expressive.

One limitation: voice features only work through calls, not recorded messages.

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

Secrets AI

• Looking for encryption details? I found none.
• Searching for data retention policies? Nothing concrete.
• Wondering if they share your intimate chats with third parties? They don't say.

The app clearly stores your conversations, but it provides zero details about what they keep, for how long, or who might access them.

The only privacy feature that actually works is discreet billing - charges appear as "Sun Clinical Laboratories" on your statement.

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.
