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

Nomi AI vs HeraHaven AI

I've spent a full week with both Nomi AI and HeraHaven 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.

HeraHaven AI

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

HeraHaven AI

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

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.

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.

Safety & 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.

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.
