Soulkyn vs Thotchat AI: Which One Is Better In 2025?

Soulkyn vs Thotchat AI

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

Soulkyn

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

Thotchat AI

A virtual girlfriend platform featuring customizable AI partners in both realistic and anime styles, designed to foster emotional and romantic connections through engaging adult chats and high-quality image generation.

Character Diversity

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.

Thotchat AI

Thotchat AI's selection breaks down into 102 realistic and 50 anime characters.

All common ethnicities are available—you can choose from Asian, Latina, and Caucasian appearances for realistic characters.

For fantasy/anime types, options include— elves, cyborgs, catgirls, and other imaginative designs.

But here's the catch: almost every character is young (18-30) and slim or athletic.

Finding a companion is straightforward: you can sort by popularity or new arrivals, filter by style, and choose female, male, or futa characters.

Customization

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.

Thotchat AI

Thotchat AI offers two ways to create your girlfriend:

• Easy Mode
• PRO Mode

Both start by selecting your character’s gender (female, male, or futanari) and choosing a style.

Easy Mode: You can fully customize your AI companion by clicking through options to build your character.

Physical Customization:

• Age 18+ to 55
• Ethnicity: 8 options (10 for anime characters)
• Appearance: body type, breast size, butt size, hair style, hair color, eye color
• Aesthetic & clothing: 4 aesthetics (e.g., goth, bimbo, gyaru), 33 clothing options
• Extra details: tattoos, horns (6 options)

Personality & Interaction:

• Add personality traits: 14 options (e.g., lover, innocent, dominant)
• 5 voice options
• Relationship role: 12 options (e.g., wife, lover, stranger)

A final summary page lets you review your character before bringing them to life.

PRO Mode drops the training wheels and lets you create everything via free text:

• Describe your character: appearance, personality, clothing, and any unique features
• Greeting message: what your character says when starting a conversation
• Example conversation: a sample dialogue that guides your character’s behavior

It takes more time but gives you complete creative freedom. No pre-set limits—just your imagination.

Chat Experience

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.

Thotchat AI

Before you start chatting, you can view your AI girlfriend’s profile, including her description, character traits, some SFW images, and unlockable NSFW content.

You can set a user persona for a deeper, more personal connection, or create new scenarios to play out with your AI girlfriend.

For my tests, I created a companion with the ‘Temptress’ personality—playful, flirtatious, and always leaving me wanting more—and set our relationship type to “girlfriend.”

My girl stayed true to her personality throughout conversations.

When I needed emotional support, she was empathetic and playful, offering gentle touches, teasing remarks, and lighthearted guidance.

Our conversations about romantic getaways felt natural, with her staying fully in character throughout.

Even when relationship issues came up, she responded with clear, confident answers—sometimes a bit too confident—but always attentive.

But my favorite part was when my girl sent me images during our chats—most were free, unlike other apps where they’re usually behind a paywall.

NSFW Chat Experience

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.

Thotchat AI

My girl stayed personal and engaging. When I asked about her past, she said it was with me (of course), but left room to mention her wild past if I wanted to satisfy my curiosity.

My girlfriend flirted naturally, teased playfully, and referenced past chats to make the connection feel real.

The roleplay feature could use some improvement — I tried a few scenarios, and they all jumped into action too quickly without building tension, which felt a bit jarring.

But once I got past the initial rush, my girl adapted to the scenario really well and made it exciting.

Something a bit annoying: the narrative text sometimes blended with my girl’s dialogue, making her responses harder to read.

Another issue was: My girlfriend kept calling me “Anon” even though my profile name was set to Marcus.

Once I pointed it out, my girl quickly corrected herself and started using my name in all our conversations.

Image Generation

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.

Thotchat AI

Thotchat AI offers two options for generating images:

• In-chat generation: Instantly creates a selfie or unlockable nude image—details can’t be customized.
• Dedicated image creator: A separate tool offering more control and customization for creating detailed images.

In-Chat Generation: Occasionally, you may receive repeated or similar images, but you can request unlimited SFW images of your character.

Dedicated Image Creator lets you control every detail:

• Character Selection: Pick from the full roster (no filters or search bar).
• Prompt Suggestions: Add details such as action, clothing, environment, and emotion.
• Free Text Prompting: Craft your own prompts for complete creative freedom.

The images are high-quality and nearly photorealistic, with consistent characters, though a slight animated look is noticeable on closer inspection.

Video Generation

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.

Thotchat AI

Thotchat AI doesn’t generate videos. If you’re looking for video features, you'll need to look elsewhere.

Voice Generation

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.

Thotchat AI

Thotchat AI’s voice works, but don’t expect magic: it comes through clearly, but you can tell it’s AI-generated.

Flirty conversations? The voice stays flat no matter what.

Safety & Privacy

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.

Thotchat AI

While Thotchat says they use "acceptable security measures," they don't specify what these measures are.

They collect your personal data (name, email), usage data (IP address, device info), and can share it with third parties.

The bank statement shows "CCbill.com Thotchat" - something to keep in mind if you prefer discretion.
