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

Joi AI vs Sakura AI

I've spent a full week with both Joi AI and Sakura 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.

Joi AI

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

Sakura AI

A character-based AI interaction platform where you can chat intimately with custom AI personalities and explore a growing community of unique characters.

Character Diversity

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.

Sakura AI

Sakura AI offers a huge collection of anime-style AI girlfriends.

The search system is straightforward—you can filter by character type (male, female, non-binary, lesbian, etc.).

When you're looking for particular character types, you can also use keywords and toggle NSFW content on/off.

The library expands regularly as users add their custom-made characters to the public collection.

Customization

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.

Sakura AI

Instead of tweaking physical features, you'll craft your character through storytelling in freeform text.

Basic customization lets you upload an image or generate one from text.

You can set gender and voice and even add a background image to your chat.

But that's not where Sakura AI shines. The real customization happens through free-text inputs.

You write your character's description, personality, and scenario from scratch and can also fine-tune how your AI responds through Model Instructions.

The platform includes a practical tagging system (Tsundere, Vampire, Non-binary, etc.) to help categorize your creation.

However, if you're looking for detailed physical customization like choosing eye color or body type, you won't find it here.

Chat Experience

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.

Sakura AI

I tested my girl in a role as my ex-girlfriend, and the girl is warm, stays in character, and keeps conversations flowing.

When I needed emotional support, my girls offered it with a bit of flirtation, and she played along naturally.

Whether my girlfriend talks about relationship concerns, her responses feel genuine and thoughtful.

The app includes a mature content warning, so you can expect adult conversations when appropriate.

The chat interface needs improvement, sometimes it's hard to distinguish narrative messages from my girl's.

NSFW Chat Experience

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.

Sakura AI

During my testing, my girlfriend kept recycling the same flirty responses, even when I tried different approaches.

The biggest letdown? Her roleplay feature. My girl switches back to being my "ex-girlfriend" and starts repeating the same lines.

I tested this multiple times - same result.

The immersion breaks faster than you can say "mood killer."

Image Generation

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.

Sakura AI

The images are clean and well-drawn, matching what you'd expect from modern anime art.

You can't control exactly what pictures you get. The app generates random images right in your chat conversations.

If you want to direct every detail of your character's appearance, you might find the randomness frustrating.

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.

Sakura AI

Sakura doesn't offer any video generation, you'll need to look elsewhere.

Voice Generation

Joi AI

Joi AI lacks voice capabilities — if you want to hear your girlfriend’s voice, you’ll need to try another app.

Sakura AI

After spending hours testing different conversations, I can tell you, the voice is clear but lacks any real personality.

Think of it this way: Whether I'm flirting, joking, or having a serious chat, Sakura's voice stays flat.

Safety & Privacy

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.

Sakura AI

While Sakura claims to use advanced encryption, I couldn't find this explicitly stated in their policy. They also store your conversations and personal information. They share data with third parties.

On top of that, payment is more complicated than their competitors, as it requires using multiple platforms and connecting them together.

Your bank statement is safe - payments appear as "GANKPTELTD".
