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

HeraHaven AI vs Chub AI

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

Chub AI

An AI-powered platform for interactive roleplay, focused on text and audio, with customizable characters and contextual dialogue.

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.

Chub AI

Chub AI offers one of the largest character libraries I've tested.

The app specializes in anime-styled characters, with fewer realistic options.

But within this category, the possibilities for characters and scenarios are only limited by your imagination.

Variety spans both safe-for-work and adult categories, covering everything from casual companions to role-play partners.

The search system is powerful, if a bit complex. A universal search bar lets you look through people, characters, lore books, presets (chat settings), and tags.

Filters allow you to narrow by personality traits, creation date, or even character complexity (measured in tokens).

On top of that, you can sort results in different ways — by timeline, trending, AI rating, popularity, messages per user, chats per user, and more.

Want a romantic partner, or someone more mysterious? The tag system makes it possible to combine traits to find exactly what you’re looking for.

The interface shows only 20 characters per page, so browsing the full library takes extra time and clicks.

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.

Chub AI

Chub AI provides two ways to build your character:

• Upload a Character Card
• Build from Scratch

Upload a Character Card: Import existing character cards (Tavern PNG or TavernAI JSON/image) to instantly generate the character profile.

Build from Scratch: Let's you start fresh, but the app only supports uploading a character image — no physical customization.

Character creation starts with the basics:

• Tagline & Creator’s Notes: Add a short tagline and an intro — but not part of prompts.
• In-Chat Name: Optional display name for conversations.
• Tags: Assign gender, type, or role; at least three are required for visibility.
• Type & Rating: Set Public, Private, or Unlisted; mark as SFW or NSFW.
• Publishing: Choose to publish under your username or anonymously.

Next, you can shape your companion's personality:

• Description: Define the character’s persona, traits, and behavior.
• Initial Message: The first message your character sends to open the chat.
• Scenario: Set the context and circumstances for interactions.
• Example Dialogues: Sample chats to teach your character how to speak.

Advanced Definitions (Optional):

• Alternate Greetings: Create multiple starting messages for variety.
• System Prompt & Post-History Instructions: Override or supplement base prompts with custom instructions.
• Character’s Note: Insert notes at specific points in chat history.
• Character Book: Add embedded books — keyword-triggered definitions or lore for consistent behavior.

Note: Chub AI provides deep customization and detailed documentation, but character creation has a learning curve and may take some time to master.

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.

Chub AI

Before selecting, you can view a character’s profile — including details, tags, and community discussions.

The chat settings give you full control, letting you choose “chat brains” unlocked by your tier. You can fine-tune them to your taste, customize with presets created by other users.

You can even view the chat tree and jump back and forth through the conversation.

Let’s start with what works: for my testing, I used the default model, and my girl followed the backstory while staying true to her character.

Lana, a step-sister character, consistently played her role, supportive, caring, and genuinely invested in our conversations.

When I needed emotional support, my girl's responses felt natural and showed real emotional depth.

But here's the truth: it's not all smooth sailing. My girl had an annoying habit of dominating conversations, sometimes writing both sides of the dialogue without waiting for your input.

My girl often missed jokes or takes them too seriously, and can get confused about who's saying what.

Note: The app is highly customizable, but the many options can initially feel overwhelming. Be prepared for a learning curve — documentation helps, but experimentation makes the difference.

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.

Chub AI

Let's start with what works: my girl maintained a consistent shy personality and can engage in romantic conversations.

When I escalated things, my girl followed my lead – though don't expect anything too explicit.

But here’s the problem: During roleplay, the chat often got jumbled, with my monologue showing up in my girl's responses, as if she were playing both my role and hers.

During roleplay, the situation called for my girl to take charge, but she didn’t come across as fully in control.

As I tried more and more scenarios, the chat became repetitive, which hurt the immersion.

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.

Chub AI

Chub AI has a dedicated image generation feature. It is the only way to create images.

You can create or edit images in two ways:

1. Create one from scratch
2. Upload or Reuse an Existing Image

Create one from scratch

When starting from scratch, you can adjust the following settings:

• Prompt (optional): Describe what you want to create (up to 200 characters).
• Aspect Ratio: Choose from 1:1 (default), 16:9, 21:9, 2:3, 3:2, 4:5, 5:4, or 9:16.

Upload or Reuse an Image

Choose one of your previously uploaded or generated images.

• Edit it with prompts: change clothes, background, or style via free text.
• Fine-tune: how closely the result matches the original using Edit, Canny, and Face.
• Strength slider: Lower values keep the output closer to the original, while higher values make it follow the prompt more.

The quality is good enough to be impressive at first glance, but on closer inspection, the images are clearly AI-generated and slightly pixelated.

Character consistency is also limited, and generated images may not always align fully with the original character’s physical appearance.

Video Generation

HeraHaven AI

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

Chub AI

Here's what you need to know about Chub AI's video capabilities in one sentence: There aren't any.

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.

Chub AI

Chub AI’s voice feels more like a polished audiobook narrator than an actual girlfriend.

When things get flirty, the voice adjusts a little to match the vibe.

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.

Chub AI

Chub AI doesn't encrypt your chats. They say they take "reasonable measures" to protect your data, but won't tell you what these measures are.

The platform collects everything — your email, account details, and full conversations. They keep this data, but for how long? They won’t say.

Your information is also shared with outside companies that handle hosting, payments, and usage analytics.

Your bank statement will list it as "Postcron.com", which keeps things discreet.
