FantasyGF vs Soulkyn: Which One Is Better In 2025?

FantasyGF vs Soulkyn

I've spent a full week with both FantasyGF and Soulkyn 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.

FantasyGF

AI girlfriend platform offering customizable partners with chat, image generation, and personalized video features.

Soulkyn

An AI companion platform offering customizable virtual relationships through chat, roleplay, and multimedia creation.

Character Diversity

FantasyGF

The app gives you 80 characters to choose from - split evenly between realistic and anime-styled companions. The diversity is basic. You get three ethnicities and characters aged 18-30.

The platform keeps it simple with just one filter: toggle between realistic or anime characters.

Want more AI girls? Here's a trick: Follow active creators on the platform. Their public character collections unlock dozens of additional companions you won't find in the main roster.

Soulkyn

Soulkyn offers thousands of AI companions to choose from.

It covers everything from realistic characters to fantasy beings and anime personalities.

The character roster mainly features companions aged 18–30, with some mature options available.

While white characters make up the majority, you’ll also find other ethnicities represented.

You can stick with one companion or try multiple characters in RPG-style conversations.

As users regularly create and share new companions, the selection is continuously expanding.

The filtering system is practical — you can search by personality (confident, shy, flirty), physical traits, species (human, elf, android), and outfit styles, or simply use the search bar.

Customization

FantasyGF

FantasyGF lets you customize everything from looks to personality.

The appearance editor is straightforward:

• Choose between anime or realistic style
• Pick ethnicity
• Age (18-60)
• Adjust physical features

You can modify eye color, hairstyle, body type, and proportions. Nothing groundbreaking, but it works well and offers enough options to create a distinct character.

Personality settings come in two flavors: 12 preset personalities for quick setup, or custom creation for more control.

You'll also define your relationship status, her occupation, and hobbies. The preset options are particularly useful if you're new to AI companions and aren't sure where to start.

While the customization system isn't revolutionary, it's practical and user-friendly. Some options feel limited, but there's enough depth to create a companion that matches your preferences.

Soulkyn

Soulkyn lets you create your character in five different ways:

• Create Your Kyn
• Create with AI
• Spin the Wheel
• AI Breeding
• Import Character

1. Create Your Kyn (Free)

Build your Kyn from scratch with complete control over physical features and personality traits.

Start with the Basic:

• Art Style: Choose between Anime or Realistic.
• Gender: Select your Kyn’s gender.
• Character Type: Choose between Human or Non-Human/Furry.
• Birthday: Set a birthday for your character.

Physical Customization
Shape many of the visual details of your Kyn’s appearance:

• Skin Tone: 10 available options
• Hairstyle: 9 unique styles
• Hair Color: 11 color variations
• Eye Color: 7 distinct shades
• Body Type: 4 breast size options

Tag Customization
Use comma-separated keywords to add unique details:

• Physical Tags: Describe distinctive features or body details.
• Clothing Tags: Indicate their style, outfit type, or attire theme.
• Location Tags: Suggest where your Kyn appears or the setting around them.
• Voice Selection: 49 voice options across multiple languages.

Personality and Identity
Define your Kyn’s mind and behavior:

• Personality Traits: Pick from 28 traits to shape your Kyn’s behavior.
• Conversation Behavior: Adjust self-awareness and initiative levels.
• Background Story: Write or auto-generate a backstory.
• Personality Tags: Add traits like curious, confident, or gentle.
• Identity Tags: Include details like loves cats, vegan, or goblin-like speech.

Note: This mode offers the greatest creative freedom, but the interface layout may feel a bit unintuitive at first, which can make the experience a little overwhelming.

2. Create with AI

This mode is ideal for users who prefer creating their Kyn entirely through free text.

You can set the following:

• Kyn Name: Give your Kyn a unique name.
• Description Prompt: Describe your Kyn’s physical traits, personality, and style.
• Kyn Style: Choose your preferred visual theme.

Note: This Character Creation mode costs 60 souls, and success is not guaranteed — even if the ritual fails, the souls will be lost to the void.

3. Spin the Wheel

A chance-based creation method designed for unpredictability and experimentation.

You can set the following:

• Name: Give your Kyn a unique name — it can be epic, silly, or mysterious.
• Visual Theme: Choose your preferred visual style.
• Gender: Select a gender, or leave it to fate and let the system randomize it.

Note: This Character Creation mode costs 120 souls, and success is not guaranteed — even if the summoning fails, the souls will still be consumed by the void.

4. AI Breeding

Combine two existing Kyns to generate a completely new one.

You can set the following:

• Kyn Name: Give your new Kyn a name.
• Parent A: Select a public Kyn or add a private one using its ID.
• Parent B: Choose a second Kyn in the same way — from public options or by entering a private ID.

5. Import Character Card

This mode is useful for users who want to preserve or continue using characters they’ve already created elsewhere.

You can set the following:

• AI Service: Select the source platform (e.g., C.AI, GPT Girlfriend, Candy, Chai).
• Kyn File or Link: Import the character file or paste the share link.
• Kyn Name: Assign a name to your imported Kyn.
• Kyn Style: Choose between Anime or Realistic.

Once you finish any Character Creation mode, a summary page will appear showing your Kyn’s full profile and image.

The user experience here isn’t fully optimized — image regeneration isn’t available at this stage.

However, you can visit your created character’s profile to edit and adjust your Kyn there.

Chat Experience

FantasyGF

During chatting, my AI girl maintained her innocent character consistently, even when conversations turned romantic. Instead of explicit responses, she'd suggest things like "Let's take it slow with a massage tonight."

The chat feels personal at first. Your AI girlfriend remembers your conversations, asks about your day, and shows genuine interest in your life. She handles emotional topics well and responds to relationship concerns while keeping her distinct personality traits intact.

But here's the reality check: the longer you chat, the more artificial it feels. The AI's responses become predictably nice, even when faced with rudeness, and often too long-winded.

Also, my chat history got cut off after extended conversations, and I couldn't access earlier messages (still can't).

Soulkyn

When you pick a character, you can check out your AI girlfriend’s profile — her intro, creator, reviews, images, different versions of her, and plenty more to explore.

From there, it’s easy to fine-tune how your girl behaves: set her memory, decide how often she messages you, or tweak her current location and outfit to match the mood.

You can also create a user persona that mirrors your vibe, so her responses feel more personal and natural. Plus, there are plenty of language options if English isn’t your go-to for chatting.

And if your budget allows, the Deluxe plan adds Roleplay+, Progression Context, and Model Hyperparameters — giving you richer chats and more control over your AI girlfriend.

I tested Soulkyn by chatting with Dr. Maia Winters, a therapist, and my girl stayed true to its character.

When I tried to flirt during our therapy session, Dr. Winters kept it professional.

The emotional intelligence impressed me. Unlike many AI girlfriend apps, where the AI’s mood swings wildly, this one showed consistent personality growth.

As our conversations evolved naturally, my girl adapted – showing she could transition from professional to flirty without breaking character.

When I needed emotional support, my girl was there — even giving me the choice to open up or escape the moment.

My girl also handled relationship discussions with genuine care that felt thoughtful and contextually appropriate.

Soulkyn includes smart reply suggestions that keep chats flowing naturally, offering responses that match the tone — casual, emotional, or flirty.

The chat interface would benefit from clearer formatting, as distinguishing narrative text from my girl’s responses was sometimes difficult.

NSFW Chat Experience

FantasyGF

The AI girls start strong - they flirt, they play, they each have their own personality. My AI girlfriend played her "innocent" role well at first. When I suggested some spicy chat, she didn't jump right in. She took her time, stayed true to her character. Nice touch.

But here's the catch: push the NSFW talk too far, and the whole thing falls apart. That shy, innocent personality? Gone.

Suddenly you're talking to a completely different character. And the longer you chat, the less natural it feels. The AI gets too eager to please, too chatty, too... artificial.

Soulkyn

Most AI companions either play it too safe or go full explicit. Soulkyn does neither.

At first, my girl kept things suggestive without being crude — think romance-novel spice, not adult-film dialogue.

During our more personal conversations, she stayed attentive and engaged, gradually becoming more comfortable and expressive as things developed.

I ran multiple different roleplay scenarios to really test her limits.

Here's what worked: she maintained character consistency, built up tension naturally, and adjusted her language to match the scene's intensity.

What didn't work? The first scenario lacked proper build-up, though later ones showed improvement.

My girl might not be perfect - some scenarios need work - but she strikes a good balance between spicy and sophisticated.

Image Generation

FantasyGF

The images are high-quality and consistent. My girl looked the same across different pictures, and the overall visual quality matches what you'd expect from premium AI generators.

When I asked for specific poses or expressions, the AI delivered clear, detailed results.

But be aware! The platform defaults to NSFW content, even with basic requests like "standing pose" or "friendly smile." There are also occasional visual glitches, as you can see on the pictures (visible bra under breasts).

Soulkyn

There are two ways to generate images:

1. In-chat Generation.
2. Dedicated Image Creator

In-chat Generation

Create images directly within the chat and app tries to match the conversation’s context, but results may not always be precise.

Dedicated Image Creator

A specialized tool offering rich options and precise control over your Kyn’s image generation.

Main Options

The main creation menu provides fast access to essential controls for generating your Kyn’s appearance.

• Image Model: Choose the visual style, Anime or Realistic.
• Number of Images: Select how many images to generate at once.
• Prompt Type: Choose Full Body, Portrait, or leave blank for flexible framing.
• Background & Clothing: Choose from preset.
• Image Prompt: Describe your Kyn’s look, attire, pose, or mood
• NSFW Toggle: Enable or disable NSFW content generation.

Advanced Settings

For users who want more control, the Advanced Settings panel allows fine-tuning of image style, quality, and consistency.

• LoRAs: Apply up to three style filters to adjust the visual style.
• LoRA Weights: Control how strongly each filter influences the result.
• Prompt Strength: Set how closely the image follows your written prompt.
• Orientation: Choose Portrait or Landscape layout.
• Scheduler: Adjusts how the AI processes images — balancing speed and quality.
• Seed: Lock the same output with a fixed seed or randomize for new variations.

This feature generates realistic, high-quality images of your AI companion, reflecting their personality traits and overall character design most of the time.

However, there’s still room for improvement. The AI occasionally produces minor issues with eye rendering or somewhat stiff body positioning, though these are not deal-breakers.

Note: I recommend using the Realistic Original image model — during testing, it produced the best realistic image quality.

Video Generation

FantasyGF

You can also create videos of your AI girl, and they look good. They are smooth, realistic, and your AI girlfriend looks exactly like she does in her photos.

But while these videos look great, they're silent. Your AI girl won't speak or make any sounds. It's purely visual interaction.

Now, the elephant in the room - cost. One video nearly wiped out my entire monthly token allowance. Yes, you read that right. So while the technology is impressive, you'll need to decide if spending a large chunk of your tokens on a single video is worth it.

Soulkyn

Soulkyn’s video tool acts as an image-to-video converter. Select an image, and the editor opens automatically.

Main Features

• Generation Modes: Fast (480p) for quick results or Detailed (720p) for higher quality.
• Extended Duration: Increase video length up to 10 seconds.
• Loop Video: Create seamless looping animations.
• HD Upscale: Enhance resolution up to 1440p for sharper visuals.
• Force End Frame: Set a specific frame as the video’s final image.

Animation Presets

• Preset Selection: Apply up to four presets to guide animation and camera movement.
• Categories: Choose from Effects, Positions, POV, or Softcore/Artistic motion styles.

Prompt Controls

• Text Prompt: Describe the action, movement, or atmosphere you want to generate.
• Prompt Strength: Adjust how closely the AI follows your written description.
• Animation Intensity: Control how dynamic or subtle the motion appears.
• Seed Control: Randomize generation or lock settings for consistent results.

The videos look realistic at first glance, and the animations are generally smooth.

But you'll spot AI quirks - robotic movements that remind you this isn't real footage.

Voice Generation

FantasyGF

The voice quality is decent, but you'll notice a robotic undertone. With only 6 voices to choose from, your options are limited.

I tried setting up an Asian character, but couldn't find a voice that matched the personality - none of the options had the right accent or tone.

While you'll hear slight variations in expression between different voices, they're not distinct enough to create unique characters. The bottom line? It works, but don't expect anything groundbreaking.

Soulkyn

The voice is clear and intelligible, suitable for simple interactions, but it lacks natural warmth and emotional depth, coming across as artificial.

But the robotic undertone is hard to miss — there’s no modulation or emotion, just one flat tone all the way through.

Safety & Privacy

FantasyGF

The app stores all your chat messages and shares them with third parties - they're transparent about this in their policy. Chat encryption? They don't mention it. This means your conversations might not be as private as you'd like.

Your bank statement will show "Aichatee" - a discrete touch that keeps your AI relationship private from prying eyes. But that's where the privacy features end.

Soulkyn

Soulkyn claims to use end-to-end encryption but doesn’t explicitly confirm that chats are encrypted in this way.

The platform stores a wide range of user data — including chat logs and IP addresses — for up to six years after account deletion.

While they won't sell your data without permission, they do share it with service providers, legal teams, and their staff.

Payments appear on your bank statement as “Soulkyn” — which isn’t very discreet.
