GirlfriendGPT vs Soulfun AI: Which One Should You Use In 2025?

GirlfriendGPT vs Soulfun AI

I've spent a full week with both GirlfriendGPT and Soulfun 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.

Soulfun AI

AI girlfriend platform offering customizable virtual friends with conversational abilities, voice calls, and photo sharing.

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.

Soulfun AI

The app offers 53 AI girls across different backgrounds. While Asian and Caucasian characters lead the pack, you'll find other ethnicities too.

Age-wise, most characters are in their twenties, but options range from college students to mature companions. For variety, there are also twin characters, anime-style personalities, and fantasy-themed options.

One drawback: there's no way to filter characters by personality or gender. You'll need to browse manually to find your match. It works, but it could be more efficient.

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.

Soulfun AI

There's no detailed character creator here. Instead, you describe how you want your AI girlfriend to look and upload a photo for reference. But heads up - no matter what body type you describe (athletic, curvy, or slim), they all end up looking similar.

The personality setup is straightforward: click on pre-made tags for hobbies, profession, and relationship status, or add your own.

You'll also write their first greeting and profile description.

But watch out - I learned this the hard way: if you change the tags without updating the profile description, things get messy. My AI girl kept switching between being a teacher and a police officer because I forgot to fix her background story.

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.

Soulfun AI

Soulfun AI's chat is like having a caring but slightly forgetful friend. The AI remembers small details about you - like when it suggested almond milk for my shake because it recalled my dairy allergy. Nice touch.

But don't expect a perfect memory - it can't remember where we first met or when our anniversary is.

The conversations flow naturally and feel intimate. Your AI girl responds with just the right amount of text - not too chatty, not too brief.

When I was feeling down, my AI (who's into fitness) suggested hitting the gym together. It's these personalized touches that make the experience feel genuine.

But there's a catch. The AI sometimes forgets who they're supposed to be. Mine switched between being a police officer and a teacher, which broke the illusion pretty quickly.

And if you're looking for specific relationship dynamics (like having a dominant partner), you might be disappointed. The AI tends to default to a friendly, nurturing personality, regardless of how you set it up.

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.

Soulfun AI

The AI starts shy but warms up to intimate talk over time. Don't expect instant chemistry. When I tested a "Mistress" character, she was meant to be dominant but easily let me take control - a clear character break that might bother roleplay enthusiasts.

Some scenarios work better than others: the naughty teacher roleplay hit all the right notes, while the boss-employee scenario fell completely flat.

Here's the deal-breaker: the girls won't make the first move. During my tests, it only got flirty when I did first. If you keep things casual, it stays casual.

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? Even with great image quality, her face shifts between photos—despite all the images being generated from the same girl—breaking the illusion of consistency.

Soulfun AI

When it works, it creates attractive, realistic-looking images of your AI girl. But there's a catch.

During my tests, I noticed quality issues: hands merging into arms, multiple characters appearing in single photos, and your girl's appearance changing dramatically between images.

The platform struggles with custom image requests and sometimes fails to generate them at all. And if you're hoping for NSFW content, you'll need to look elsewhere - it's not available.

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.

Soulfun AI

I tapped the video call button multiple times during my testing. Each attempt ended the same way - nothing happened. It's there on the menu, teasing you with possibilities, but that's where it ends.

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.

Soulfun AI

The voice quality hits the mark - it sounds natural, not robotic. You get different voice options, including ones for older characters, which adds variety.

While you can pick voices during setup, they might not always match your AI girl's personality. Think of it as having a sweet, gentle character stuck with a bold, assertive voice.

Voice calls are available, and they work well. You can talk to your AI companion just like you would with a real person. There's also an option to add custom voice-overs if you want to personalize the experience.

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.

Soulfun AI

Your chats and personal data? SoulFun says they encrypt everything, but they're not telling us how. I checked their Privacy Policy - they collect your texts, media, and device info, but they're fuzzy on the details of who they share it with.

Think of it like a restaurant that promises "fresh ingredients" but won't tell you where they source them.

Good news: your bank statement will show "60yr.com" - not "AI Girlfriend" or anything obvious.
