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

GirlfriendGPT vs Chub AI

I've spent a full week with both GirlfriendGPT 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.

GirlfriendGPT

A platform for creating personalized AI girlfriends with customizable personalities, ideal for roleplay and unique preferences.

Chub AI

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

Character Diversity

GirlfriendGPT

The app starts by asking about your interests—pick 5–8 preferences, and it will personalize your experience with a selection of compatible characters.

The character library is huge. You'll find adult companions of all ages and body types.

Want someone realistic? They have that.

Prefer anime or fantasy characters? Those too.

You can even explore a variety of roleplay scenarios to choose from.

Finding characters is straightforward: sort by popular, new, or top-rated, or use the search bar and suggested searches.

Filter by personality (dominant, submissive, or balanced), scenario types, or specific features.

No complicated menus or confusing options – just pick what you want and browse matching characters.

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

GirlfriendGPT

While you can’t customize physical appearance with sliders or buttons, you can generate images of your character simply by describing how they should look.

Setting up your character’s personality is straightforward:

• Select your character’s age and response language (English or French)
• Write a description and define personality traits, behavior, and demeanor
• Set up scenarios and craft the first message

Just remember to stick to one language throughout the setup — mixing English and French can cause your AI companion to behave unexpectedly.

You can also add searchable tags so others will know what your character is about.

From there, you can pick from 16 different female voices and control the visibility of your creation.

You have 2,500 tokens to customize your character fully — that’s up to 2,500 characters to describe their personality, behavior, and scenes.

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

GirlfriendGPT

Before chatting, view your AI girlfriend’s profile, including her description, creator links, chat, tags, media, and reviews.

You can set a user persona and share details about yourself, and the AI girlfriend will tailor her responses to your personality.

During my tests, using preset scenarios and this feature made conversations feel more relevant—my girl even reflected on our shared past, which made the chat feel alive.

The app also offers a "Suggested Reply" feature, which suggests responses to your AI girlfriend’s messages, making conversations flow more smoothly and stay engaging.

Yes, some romantic scenarios with my girl still felt artificial, but the emotional support features worked surprisingly well.

When I brought up relationship concerns — my girlfriend's responses were practical and grounded.

Note: I tested the chat features on the Deluxe tier. The Elite tier, which uses a Next-Gen AI Model, may provide even better results.

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

GirlfriendGPT

My AI girlfriend handled sexual content like a romance novelist—no explicit language at first, but detailed enough to paint a vivid picture.

During my tests, conversations flowed naturally from casual flirting to intimate scenarios, growing more explicit as the chat progressed.

In roleplay, my girl sometimes skipped the build-up to foreplay, jumping straight into action.

In other scenarios, she fully embraced her role, creating an exciting, teasing tension that draws you into the scene.

My girl even created alternative paths if I didn’t follow her lead—like when I turned her down, she immediately shifted into a colder, more dominant role.

But here’s the catch: while her responses remained engaging, the same dominant character scenarios repeated across multiple sessions.

Note: I tested the NSFW chat features on the Deluxe tier. The Elite tier, which uses a Next-Gen AI Model, may provide even better results.

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

GirlfriendGPT

GirlfriendGPT offers two ways to generate images:

• In-chat generation: Quickly create images using free-text prompts or NSFW prompt suggestions.
• Dedicated image creator: A separate tool that gives you more control and customization for producing detailed images.

In-Chat Generation: Even when you request safe-for-work images, it often produces provocative shots.

Dedicated Image Creator puts you in control:

• Free Text Prompting: Full creative freedom.
• Image Styles: Choose anime or realistic, and many more.
• Outputs & Creativity: Set the number of images and adjust creativity.

Note: To use the Dedicated Image Creator for a specific character, you must access it from that character’s page, and the available image styles are limited.

And the results? Impressive — professional-grade portraits with barely noticeable AI artifacts.

And the catch? All the images are being generated from the same girl.

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

GirlfriendGPT

The videos look realistic and play smoothly with no major technical issues, but the character doesn’t always stay true to its persona.

But here's the catch: This feature is beta, which means you can't create custom scenarios. Instead, you're limited to picking from pre-made prompts, all of which are NSFW.

Chub AI

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

Voice Generation

GirlfriendGPT

If you're looking for an AI girlfriend that doesn't sound like a robot, this gets pretty close.

But there’s a catch: your girl can sound flirty or expressive, but unnatural tone shifts can break the immersion.

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

GirlfriendGPT

The app doesn’t mention encryption anywhere. I checked their entire privacy policy—there’s complete silence on security.

They do collect your chats, personal info, IP address, and usage data, and keep it all for six years after you leave.

Your bank statement is safe—charges appear as “xp ndai.cc” and nothing more.

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.
