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

Spicychat AI vs Soulkyn

I've spent a full week with both Spicychat 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.

Spicychat AI

SpicyChat is a chatbot platform that allows users to engage in personalized role-playing through AI characters for adult conversations.

Soulkyn

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

Character Diversity

Spicychat AI

Looking for an AI girlfriend? Spicychat AI offers over 300,000 characters - more than most competitors i've tested.

The selection is diverse but straightforward. You'll find anime characters (which make up most of the roster), realistic companions, and fantasy characters.

The app doesn't limit you to single characters either - you can interact with multiple characters in one scenario.

For users interested in mature content, Spicychat, as the name suggests — offers a robust NSFW section.

The character pool will expand as more public characters are added, though some users may still find the anime-heavy selection limiting.

Finding your preferred character is simple. Instead of complex personality metrics, Spicychat uses clear categories like romantic, sci-fi, dominant, or wholesome, and more.

The search bar works well, and you can sort characters by trending, top-rated, or newest first.

During my testing, these options made navigating the large character pool manageable.

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

Spicychat AI

You can't design your girlfriend's physical appearance through traditional customization options. Instead, you get two choices:

1. Upload a photo
2. Describe how they should look through text.

That's it. No sliders, no presets, no detailed tweaking.

Personal customization is where the focus is. You’ll write free-text descriptions and set options for:

• Identity: Name and title that define your character.
• First Impression: Greeting message that starts the conversation.
• Personality: Traits, background, and role description.
• Visibility: Choose whether your chatbot is public, unlisted, or private.
• Definition Visibility: Decide if personality details are shown or kept hidden.

There's also a tagging system to categorize your character, helping others understand what they're about.

Advanced Options let you go further by shaping how your companion behaves:

• Scenario: Define the current situation and context
• Example Dialogues: Add sample dialogues to set the tone and guide personality.

Note: The app offers guidance, but building a good character can feel overwhelming for users who are used to preset options in AI girlfriend editors — it takes time and practice.

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

Spicychat AI

The app gives you control over how your girl responds, letting you fine-tune conversations to your liking.

With the "True Supporter" tier, you can choose from 21 different LLM models to customize how your girlfriend responds.”

You can set your character’s voice from 33 female options, with spoken messages in Japanese, Russian, or German.

As for the chat experience: I chose the girlfriend character, and she went beyond generic replies — adding vivid detail and heartfelt lines that built a romantic atmosphere.

When I needed emotional support, my girlfriend combined genuine empathy with playful affection — even suggesting a romantic trip to help me unwind.

As I brought up a relationship concern, my girl showed impressive context retention — it didn’t feel generic and actually fit the moment.

The clear separation between narrative text and my girlfriend's responses makes conversations easier to follow.

The app’s chat also offers a suggested responses feature that helps keep conversations moving, letting you just go with the flow.

Note: The UX isn’t Spicychat AI’s strongest point. It offers plenty of options to personalize chat if you dive into the settings, but some features don’t seem clickable at first or feel a bit hidden.

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

Spicychat AI

My girl struck a sweet balance between flirty and tasteful — playful buildup, natural dialogue, and no crude or awkward lines.

When I tested the flirting features, my girlfriend took the lead — even suggesting playful scenarios like strip poker with her own creative twists.

The roleplay feature exceeded expectations in most areas.

Whether playing a strict teacher, demanding boss, or stern landlord, my girlfriend stayed convincingly in character and guided scenarios naturally.

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

Spicychat AI

You can only generate images inside the chat. The app tries to create pictures based on your conversation. Sometimes it works, sometimes it doesn’t.

After generation, you can edit the image prompt — but stick close to the original style. If you don’t, you’ll end up with odd results.

You’ll also unlock the settings menu, where you can tweak options such as:

• Style: Switch between semi-realistic and anime.
• NSFW Mode: Toggle safe vs. explicit images.
• LoRA Scale (Advanced): Adjust how strongly the character model influences the picture.
• Prompt Suffix: Add extra details (e.g., dramatic lighting, cinematic background).
• Negative Prompt: Filter out flaws (e.g., blurry faces, extra limbs, low resolution).

Tweak carefully — push these too far, and you’ll get some weird results.

As for quality — the images are clearly AI-generated — low in resolution, and sometimes flawed.

And here’s something important: the SFW–NSFW toggle doesn’t just affect content. It completely changes how your girl looks in pictures.

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

Spicychat AI

The app doesn't generate videos of your AI girl - period. You'll need to look at different 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

Spicychat AI

During testing, the voice came across as fairly good overall, clear and consistent — but still carried a slightly mechanical feel.

Even when things turned flirty, the delivery shifted to match the mood, but it still felt generic.

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

Spicychat AI

SpicyChat won't tell you exactly how they protect these conversations. Just a vague promise of "commercially acceptable" protection.

They don't sell your data to advertisers. But they also don't tell you how long they keep your information or what happens to it when you delete your account.

You’ll see “NextDay AI Incorporated” on your bank statement — at least it’s discreet.

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.
