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

Aimour vs Chub AI

I've spent a full week with both Aimour 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.

Aimour

An AI-girlfriend platform offering virtual partners, with features like natural-sounding voices, mature content settings, and realistic relationship progression.

Chub AI

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

Character Diversity

Aimour

Aimour offers 54 unique characters:

• 41 realistic
• 13 anime-styled

But here's what makes it different: you'll find girls in wheelchairs, grandmothers, expecting mothers, and even characters with Down syndrome.

The character selection covers various body types, from athletic to curvy, though most are in their twenties.

Each character costs 300 coins to unlock, and you'll get 350 coins just for signing up - enough to test your first girlfriend.

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

Aimour

There's no customization in Aimour. You'll need to accept them exactly as they come, or consider other options that offer the flexibility you're looking for.

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

Aimour

Aimour treats your relationship like a game — each level unlocks new layers of your AI girlfriend’s personality and new chat features - you chat, give gifts, and level up.

The experience starts simple: a quick tutorial and a girl who's genuinely interested in getting to know you.

No forced flirting or artificial chemistry at Level 1. Instead, my girl warmed up naturally as our bond grew stronger.

Here's what works: genuine emotional support, warm affirmations, and clear communication during tough conversations.

What doesn't work? You can't access older messages once you've chatted for a while.

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

Aimour

The core of the experience is "Spicy Mode," offering three flavors of naughty chat:

• Dominant
• Submissive
• Gentle

Each style has its own personality, and most of them use very explicit language, often including strong sexual content and provocative dialogue.

But here's the catch: once your girl has locked in a dominant style, you'll need to make a change in spicy mode if you want to put an end to a certain scenario.

Messages are limited to 125 characters, and role-play scenarios jump straight to action without build-up.

Don't expect deep, elaborate fantasy scenarios. Think quick, spicy exchanges rather than long, detailed adventures.

One thing to note here: Aimour caters to users with highly specific or even taboo fantasies, offering room to explore themes that many other platforms either restrict or shy away from entirely.

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

Aimour

Each image is crisp, detailed, and attractive, with my AI girlfriend’s core features staying consistent and only slight body variations.

The app offers two straightforward options for photo generation:

• Spicy Mode off: generates fully clothed photos
• Spicy Mode on: reveals more intimate shots.

One catch - you can't tell the AI which poses or scenes to create. It makes those choices for you.

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

Aimour

AI MOUR doesn't create new videos - it just puts your girlfriend's face on existing clips from their library. During my testing, I found both good and bad news.

The good? You get instant access to videos - no waiting around for AI to generate something.

The bad? You can't request specific scenarios. You're limited to whatever pre-made clips they have in their database.

Chub AI

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

Voice Generation

Aimour

Here's what you'll experience: During regular conversations about daily topics, the voice maintains a casual, friendly tone.

When things get emotional, the voice adapts accordingly, similar to how a real person might adjust their speaking style.

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

Aimour

Your chats and photos travel through SSL encryption - the same security that banks use. However, they store your data, including messages, photos, and usage.

They share certain information with partners who help operate the service, such as tech support and website analytics providers.

Your bank statements remain discreet, showing only "Ads Boost."

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.
