CrushOn.ai vs Soulkyn: Which One Is Better In 2025?

CrushOn.ai vs Soulkyn

I've spent a full week with both CrushOn.ai 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.

CrushOn.ai

Adult conversational platform for AI girlfriend creation with text- and audio-based features, supporting multiple language models.

Soulkyn

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

Character Diversity

CrushOn.ai

Looking for an anime-focused AI companion? CrushOn.ai specializes in exactly that.

Their character library is built specifically for fans of anime, fantasy, and cartoon personalities - not realistic characters.

The selection goes beyond standard options. Instead of basic ethnicity choices, you get fantasy characters like vampires, demons, and elves.

Finding your perfect match is straightforward: browse by categories like Popular, Trending, or Editor’s Choice.

You can also refine your search by selecting character tags like Femboy, Futanari, Game, Furry, or Lesbian—or simply use the search bar to get exactly what you want.

Most characters come from the user community, so the selection grows daily—though quality may vary.

Worth noting: CrushOn.ai focuses on NSFW characters, especially anime-inspired ones. If that’s what you’re after, it’s a solid match.

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

CrushOn.ai

CrushOn.ai gives you two ways to create within the app:

1. Create a character
2. Create a target game

Create a Character

This option provides two ways to build your character:

• Upload a character card
• Build from Scratch

Upload a Character Card: Import existing character cards with support for Pygmalion, Text Generation, or TavernAI (JSON or image).

Building from scratch: Offers control, but the app only lets you upload a character image — no physical customization.

Personality builder customization is done through free text input of your character’s traits — no presets provided. You can set up the following:

• Basic Info: Name, Age, Gender
• Intro & First Greeting
• Rating: Sensitive words and topics are automatically blocked.
• Character Profile: Personality (detailed description), Appearance, Scenario (environment)
• Tags: Keywords to help others find your character

You can pick from 40 female voices and control who can see your character.

In Chat Settings, select a recommended LLM model to ensure the best balance and dependable performance for your character.

Target Play

CrushOn.ai includes a unique Target Play feature that gamifies conversations. With it, you can:

• Create a character for the game
• Set a target name and description
• Define rules for how scores change during interactions
• Adjust the initial score and maximum rounds, with progress tracked automatically

This system lets you set shared goals with your AI companion and follow progress as your interactions unfold.

Note: CrushOn.ai gives you full creative freedom with text and provides detailed guides to support character creation, though the process can still feel overwhelming for beginners.

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

CrushOn.ai

Before chatting, you can view your AI girlfriend’s profile, which includes her introduction, creator, chat history, reviews, and more.

You can also set a user persona by sharing details about yourself, and the AI girlfriend will adjust her responses to match your personality.

Chat personalization lets you tweak behavior with presets like “Don’t refuse input,” “Reduce repetition,” or add your own rules.

The app also lets you change your character’s voice, with multiple options for speech, narration, and volume control.

Another feature is group chat, where you can invite up to five characters from the roster and set a shared background story.

CrushOn.ai’s chat offers suggested responses that keep conversations moving, letting you simply go with the flow.

The chat experience largely depends on the LLM model you choose. For my testing, I used Taurus Pro 8K, which is currently the most popular option.

I chose a loving, caring girlfriend-type character who adapted to my style with playful, romantic consistency.

As our chat went on, my girlfriend’s character grew more flirty and playful, keeping a teasing, seductive charm while still adapting to my tone.

While my girlfriend is great at playful, flirty banter, she often sidesteps deeper emotional conversations by shifting back into a lighter, teasing tone.

For example, when I asked for emotional support, my girlfriend began with care and understanding, but soon shifted into flirty ‘how to unwind’ suggestions instead.

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

CrushOn.ai

The good? My girl was definitely game for intimate chats and wasn't shy about sexual topics.

Some roleplay scenarios actually hit the mark, building tension that felt natural.

But here’s the catch — when things got going, my girl sounded like a broken record, even though I’d checked the option to reduce repetition.

During my tests, my girl sometimes lost perspective—starting a story about us but then switching to “he,” which felt like a generic memory instead of our shared experience.

Even stranger, a character I created and set to “unfiltered” still refused to respond to certain sexual topics.

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

CrushOn.ai

Let’s cut to the chase — CrushOn.ai doesn’t have an image generation feature.

Instead, it offers only a few user-created characters with limited anime images that can be triggered during chat.

The system is straightforward: if your AI girlfriend has images, your character will display them in her messages to match the scenario — with varying success.

And the quality? The images are mostly well-drawn anime-style pics, but it really depends on what the user has uploaded.

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

CrushOn.ai

If seeing your companion's face and expressions matters to you, you'll want to explore other options.

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

CrushOn.ai

My girl spoke naturally — no robotic undertones or awkward pauses like you might expect from artificial speech.

During testing, I noticed that when conversations shifted from casual to intimate, my girlfriend's tone became noticeably more flirtatious.

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

CrushOn.ai

Despite having basic security measures, CrushOn.ai isn’t transparent about how it protects your chats.

CrushOn.ai stores all chats as anonymized conversations for AI training, but it also collects additional data and shares it with advertisers, vendors, and business partners.

The app shows up as “subscribestar.com” on your bank statement — a small but useful layer of discretion.

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.
