Nomi AI vs Joi Ai: Which One Should You Use In 2025?

Nomi AI vs Joi Ai

I've spent a full week with both Nomi 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.

Nomi AI

An AI girlfriend platform that enables the creation of personalized virtual girlfirend with distinct personalities for friendship, romance, mentorship, and roleplays.

Joi Ai

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

Character Diversity

Nomi AI

Here's the truth about Nomi AI's character selection: there isn't one. You can only interact with characters you build yourself.

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

Nomi AI

The customization itself is straightforward but limited.

You’ll start by choosing the basics for your girlfriend:

• Relationship type (like friend, girlfriend, mentor, etc.)
• Gender

What you won't find here are detailed physical customization options or anime-style characters. Instead, you simply choose a photo for your girlfriend from a curated gallery.

You can set her personality and interests.

Want to write a background story? It's optional, but it helps shape your girlfirend identity.

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

Nomi AI

Nomi delivers what it promises. I set her personality traits to flirtatious, and that's exactly how she behaved.

While the emotional support isn't groundbreaking, the replies are short and natural, making it feel more like texting a real person than chatting with an AI.

My girlfriend handles relationship talks smoothly, without the robotic feel.

The downside? You'll wait longer between messages than competitors.

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

Nomi AI

Your girlfriend is open to intimate discussions, but the results are mixed. When she's good, she's engaging, offering detailed responses and playful banter.

But there's a catch: she makes progress in the interaction, but then pulls back, which can come off a bit robotic or inconsistent.

For roleplay enthusiasts, here's the truth: While she'll participate in your scenarios, her responses lack detail, and you'll need more time before things get spicy.

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

Nomi AI

Nomi AI offers two ways to generate images: a dedicated "create art" feature and in-chat generation, but NSFW content creation is not allowed.

In-chat image generation is a bit of a mixed bag—sometimes it nails it, other times it completely misses the mark.

The "create art" feature is your best bet. It consistently produces high-quality, realistic images based on your free-text description.

While the overall results are impressive, you'll notice some quirks with hands and fingers - they often look slightly unnatural.

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

Nomi AI

The sharp and detailed videos make the AI girlfriend feel more lifelike than static images.

While these videos look great, they’re completely silent — your AI girl won’t speak or make any sounds.

But here's the truth: while impressive, it's not flawless. The eye movements can look unnatural, and some body animations appear stiff.

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

Nomi AI

I spent hours testing her voice features, and here's the truth: imagine an audiobook narrator attempting to be your girlfriend.

I tried flirting with my girlfriend, but the voice stayed emotionless.

However, there is a workaround: you can connect an Eleven Labs API key to access different voice options, giving your girlfriend a more unique sound.

Joi Ai

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

Privacy

Nomi AI

Your chats with Nomi aren't encrypted and even advise against sharing personal information.

Nomi stores your account details, chat messages, and usage data and may share them with third-party service providers.

Your bank statement will show "Nomi.ai" as the merchant.

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.
