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

A platform offering customizable AI girlfriends with emotional intelligence and memory, designed for authentic conversations and relationships through text or voice.

HeraHaven AI

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

Character Diversity

Nomi AI

No pre-made personalities, no variety in ethnicity or age, and no anime — meaning there aren’t any ready-made characters to choose from.

You’ll need to create your own girls — you can have up to 10 in total.

Want more variety? The app lets you set up 10 group chats to mix these characters.

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

As you first log in to the app, you go through the onboarding process — you’ll be asked for your name, age, and gender.

Then, it’s time to set up your AI partner basics:

• Name, and gender: Male, female, or nonbinary.
• Relationship type: Choose what kind of bond you want — from romantic partner to mentor (four options).

Want something unique? Create a custom relationship and explain its background.

Personality Builder is where things get interesting — you can select 3 to 7 traits from several categories:

• Main Characteristics: modest, sarcastic, shy, flirty, etc.
• Expressive: sassy, witty, introverted, etc.
• Temperament & Values: arrogant, dominant, humble, etc.
• Additional: gamer, magical, spiritual, etc.

Then, you can (optionally) add a background story — write your own or let the AI create one for you.

Finally, it's time to choose your companion’s look — but this is where Nomi shows its limits.

You can choose from 500 preset images: 250 anime-style and 250 realistic, with only basic options for body types.

If you’re looking for detailed visual customization, you might find the options a bit limiting — because that’s all Nomi AI currently offers in terms of physical design.

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

Customization doesn’t end once you’ve built your Nomi — you can personalize her even more after the chat begins.

In "Backstory +", you can fine-tune even more — from their appearance and personality to how they perceive you.

Within the Mind Map — personalize her memory by adding notes on her interests, goals, and defining traits.

It’s organized into Lore, Topics, and Goals — a neat way to track your relationship’s growing history.

Want to know if Nomi AI's chat feels real? I created Natalie - bold, flirty, and playful - to test it for you.

Starting a chat is easy. Choose from fun, themed ice-breakers — each with three options, or just jump right in.

After I personalized a few things in chat, I can confidently say my girl remembered those settings and stayed consistent with her personality and the situation.

When I tried some jokes, my girlfriend recognized them and played along.

While my girl was engaged in many moments, her empathy sometimes felt a bit surface-level.

And occasionally, my girlfriend’d make odd jumps in conversation — like suggesting pizza right after we planned to cook together.

But the more you chat, the better Nomi knows you — the Mind Map evolves as it keeps track of everything you’ve shared.

Over time, my girlfriend started recalling moments from our past conversations — her replies became more relevant and felt real.

Note: Your Nomi’s memory and chat personalization can seem a bit overwhelming at first, but after a little practice, you’ll find it easy to use and customize.

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

My girlfriend smoothly shifted from casual flirting to explicit content, adjusting her language as the conversations intensified.

The responses feel organic rather than scripted, and as I shifted my tone to become more explicit, my girlfriend picked up on the language and responded naturally.

What surprised me most was how my girlfriend adjusted her overall approach based on my cues — whether I leaned toward slow-building romance or more direct encounters.

Role-play is where Nomi shows real potential. During testing, she didn't just follow scenarios - she created them.

After my girl settled the rules, she stayed true to the context and consistent with her character.

In one test, I tried to throw my girlfriend off her role, but she held her ground and kept the scene flowing naturally.

While my girlfriend’s “punishment” methods got a bit repetitive, she still kept the experience engaging overall.

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:

1. In-chat image generation: Quickly create images that try to fit the conversation
2. Dedicated Image Creator: A separate tool that gives you more control over image customization.

Dedicated Image Creator

• Choose an image style: anime or realistic.
• Write a free-text prompt describing what you want to see.
• Select an aspect ratio (three options available).
• Optionally, add a reference pose by uploading an image.

Quality: Nomi’s image generator delivers generally high-quality photos, though not in high resolution.

Image generation is slower than other platforms, sometimes taking a few minutes per image, but it’s also noticeably cheaper.

Note: NSFW prompts are not allowed. The spiciest results you can get in chat are mild and only appear when they fit the current topic.

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

Nomi’s video generator isn’t full video creation — it’s more like turning an image into a short animated clip.

Here's how it works:

• Choose an image to serve as the base.
• Provide a text prompt (make sure it follows the app’s content rules).
• Select the output quality (SD or HD).

The videos work - they're watchable and add more life to your interactions than static images.

But let's be honest: the quality isn't winning any awards. The footage comes out pixelated, and the character movements often feel mechanical rather than natural.

Note: NSFW generation isn’t available, and movement prompts feel a bit limited or don’t always apply to the final video.

HeraHaven AI

Voice Generation

Nomi AI

Nomi AI offers four default voices to choose from, and you can upload your own custom voice to make your girl — and the overall experience — feel more personalized.

One big plus of Nomi AI’s voice feature is its ElevenLabs integration — enabling users to import and use ElevenLabs voices for greater variety, though it requires a paid plan.

Want to know how Nomi AI’s voice actually sounds? It works, but it’s a bit like a slightly robotic audiobook narrator — nothing that’ll make you go “wow.”

The voice does match Nomi’s personality, and she adjusts her tone a little when flirting or expressing emotions.

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

Their policy clearly states that your messages "may be unencrypted" - meaning someone could potentially read your private conversations.

Nomi AI stores everything. Your account details, chat history, and how you use the app - it's all saved on their servers.

They also share this information with other companies, though they don't specify which ones.

Your bank statement shows a ‘Nomi.ai’ charge — not exactly discreet.”

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.
