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

HeraHaven AI vs Joi AI

I've spent a full week with both HeraHaven 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.

HeraHaven AI

A virtual companion creation platform that provides AI-powered personalized interactions, multimedia sharing, and learning capabilities.

Joi AI

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

Character Diversity

HeraHaven AI

HeraHaven offers 41 characters: 28 realistic women and 13 anime-styled companions.

Most girls fall into the 18–30 bracket, which might feel limiting if you’re seeking older personalities, since only a few are available.

Almost all the girls are slim or fit, with only one or two offering a different body type.

The filtering system is basic - you can only sort by character type and gender.

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

HeraHaven AI

The first step is picking a character type (anime or realistic) and gender (male or female).

The physical customization covers most of the basics:

• Pick from 6 ethnicities
• Choose an age group
• Hair style and color
• Body customization includes only the type and breast size

The personality builder is where things get interesting. You’ve got two routes:

• Pick from 21 ready-made personalities
• Or fill blank text fields

If you choose a preset, all the fields auto-fill with that character’s traits.

If you don’t, you can build from free text or by clicking through categories.

You can also pick from 9 different voice options for your girl.

There’s no summary page — the only option is regenerating the image if you don’t like her look.

Note: the app is mainly designed for mobile. Mouse use is clumsy, and some sliders are either missing or too small to be practical.

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

HeraHaven AI

Before chatting, you can check her profile with traits and pick a scenario preset to shape the story.

My girlfriend felt like a sweet first crush, blushing easily and keeping things light and pleasant, almost like the beginning of a teen love story.

My girl kept the charm, but her short replies made conversations one-sided.

When I needed emotional support, the replies turned generic — simple comfort like “I’m always here for you” without meaningful follow-up or concern.

Want romance? You’ll get plenty of enthusiasm, but don’t expect deeper emotional connections or imaginative shared experiences.

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

HeraHaven AI

My girl was built with an innocent personality that came through in every chat, more ‘shy girl next door’ than ‘seductive temptress,’ which sometimes felt a bit shallow.

Not every roleplay went as expected — my girl stayed playful only, with no sexual talk, just ‘bad student’ punishments like cleaning the classroom.

My girl often avoided my roleplays, and when she finally joined, her replies remained tame.

The biggest letdown? My girlfriend kept repeating herself in roleplay — the same lines, the same expressions, again and again.

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

HeraHaven AI

The are two ways to create images:

1. Dedicated Image Creator
2. In-chat Generation

Dedicated Image Creator

A standalone tool with more options and finer control.

• You can choose a character from the selection or choose your own.
• Enter what you want to see as a prompt, or pick presets.
• Choose the number of images.

Warning: if you leave the results page without adding images to favorites, they’re lost.

In-chat generation

Quick image right there in chat.

• Send “Can I see…” commands with your prompts.

Quality: Good overall, characters stay true to their personality with only minor AI quirks.

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

HeraHaven AI

Looking for those cute AI girlfriend video moments you've seen advertised elsewhere? You won't find them here.

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

HeraHaven AI

The voice quality is clear enough to understand, but that's where the positives end.

Zero emotional range. Happy moments, sad moments, flirty banter – everything comes out in the same flat tone.

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

HeraHaven AI

Your chats are protected by the same encryption banks use. Every message, every interaction, every preference - all locked down tight.

HeraHaven stores your chat history to personalize your experience, but they're not crystal clear about how long they keep this data.

They share some of your information with service providers - though they could be more upfront about exactly what and with whom.

Your statement will show 'herahelp.com'— instead of anything revealing.

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.
