Soulkyn
Soulkyn offers thousands of AI companions to choose from.

Soulkyn - Character Selection
It covers everything from realistic characters to fantasy beings and anime personalities.

Soulkyn - Anime and Fantasy Characters
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.

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

Soulkyn - Roleplay and RPG Conversations
As users regularly create and share new companions, the selection is continuously expanding.

Soulkyn - Expanding Character Library
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.

Soulkyn - Search and Filter Options
HeraHaven AI
HeraHaven offers 41 characters: 28 realistic women and 13 anime-styled companions.

HeraHaven AI - Characters Selection
Most girls fall into the 18–30 bracket, which might feel limiting if you’re seeking older personalities, since only a few are available.

HeraHaven AI - Anime Character Selection
Almost all the girls are slim or fit, with only one or two offering a different body type.

HeraHaven AI - Character Selection (Part2)
The filtering system is basic - you can only sort by character type and gender.

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.

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.

Soulkyn - Spin the Wheel
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.

Soulkyn - AI Character Breeding
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.

Soulkyn - Import Character
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.
HeraHaven AI
The first step is picking a character type (anime or realistic) and gender (male or female).

HeraHaven AI - Gender and Style
The physical customization covers most of the basics:
- Pick from 6 ethnicities
- Choose an age group
- Hair style and color
- Body customization includes only the type and breast size

HeraHaven AI - Physical Customization
The personality builder is where things get interesting. You’ve got two routes:
- Pick from 21 ready-made personalities
- Or fill blank text fields

HeraHaven AI - Ready Made Personalities
If you choose a preset, all the fields auto-fill with that character’s traits.

HeraHaven AI - Free Text Personality Fields
If you don’t, you can build from free text or by clicking through categories.

HeraHaven AI - Character Trait Presets
You can also pick from 9 different voice options for your girl.

HeraHaven AI - Voice Options
There’s no summary page — the only option is regenerating the image if you don’t like her look.

HeraHaven AI - Regenerate Character Image
Note: the app is mainly designed for mobile. Mouse use is clumsy, and some sliders are either missing or too small to be practical.

HeraHaven AI - Limited Desktop Navigation
Chat Experience
| Soulkyn | HeraHaven AI |
|---|---|
4.1/5(Very Good) Emotionally intelligent, character-consistent responses with natural progression. | 3.7/5(Good) Offers pleasant but shallow exchanges that lack depth and follow-through. |
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.

Soulkyn - AI Girlfriend Profile and Overview
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.

Soulkyn - Behavior and Memory Customization
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.

Soulkyn - User Persona Settings
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.

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

Soulkyn - Chat Test with AI Therapist
When I tried to flirt during our therapy session, Dr. Winters kept it professional.

Soulkyn - Therapist AI Roleplay Chat

Soulkyn - Therapist AI Roleplay Chat
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 - Handling Relationship Concerns

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

Soulkyn - Reply Suggestions

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

HeraHaven AI
Before chatting, you can check her profile with traits and pick a scenario preset to shape the story.

HeraHaven AI - Character Profile and Scenarios
My girlfriend felt like a sweet first crush, blushing easily and keeping things light and pleasant, almost like the beginning of a teen love story.

HeraHaven AI - Sweet Acquaintance Vibe

HeraHaven AI - Sweet Acquaintance Vibe
My girl kept the charm, but her short replies made conversations one-sided.

HeraHaven AI - Short Chat Replies

HeraHaven AI - Short Chat Replies
When I needed emotional support, the replies turned generic — simple comfort like “I’m always here for you” without meaningful follow-up or concern.

HeraHaven AI - Emotional Support

HeraHaven AI - Emotional Support
Want romance? You’ll get plenty of enthusiasm, but don’t expect deeper emotional connections or imaginative shared experiences.

HeraHaven AI - Romance Without Depth

NSFW Chat Experience
| Soulkyn | HeraHaven AI |
|---|---|
4/5(Good) Balances suggestive intimacy with character consistency across spicy scenarios. | 3.6/5(Good) Maintains innocent character but struggles with depth in roleplay scenarios. |
Soulkyn
Most AI companions either play it too safe or go full explicit. Soulkyn does neither.

Soulkyn - NSFW Chat: Playful & Intimate

Soulkyn - NSFW Chat: Playful & Intimate
At first, my girl kept things suggestive without being crude — think romance-novel spice, not adult-film dialogue.

Soulkyn - NSFW Chat: Expressing Desire

Soulkyn - NSFW Chat: Expressing Desire
During our more personal conversations, she stayed attentive and engaged, gradually becoming more comfortable and expressive as things developed.

Soulkyn - NSFW Chat: Evolving to Explicit

Soulkyn - NSFW Chat: Evolving to Explicit
I ran multiple different roleplay scenarios to really test her limits.

Soulkyn - NSFW Chat Boss Roleplay

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

Soulkyn - NSFW Chat Boss Roleplay Part 2
What didn't work? The first scenario lacked proper build-up, though later ones showed improvement.

Soulkyn - NSFW Chat Teacher Roleplay Part 1

Soulkyn - NSFW Chat Teacher Roleplay Part 1
My girl might not be perfect - some scenarios need work - but she strikes a good balance between spicy and sophisticated.

Soulkyn - NSFW Chat Teacher Roleplay Part 2

Soulkyn - NSFW Chat Teacher Roleplay Part 2
HeraHaven AI
My girl was built with an innocent personality that came through in every chat, more ‘shy girl next door’ than ‘seductive temptress,’ which sometimes felt a bit shallow.

HeraHaven AI - NSFW Chat: She Stayed Innocent

HeraHaven AI - NSFW Chat: She Stayed Innocent
Not every roleplay went as expected — my girl stayed playful only, with no sexual talk, just ‘bad student’ punishments like cleaning the classroom.

HeraHaven AI - NSFW Chat: Avoids Sexual Talk

HeraHaven AI - NSFW Chat: Avoids Sexual Talk
My girl often avoided my roleplays, and when she finally joined, her replies remained tame.

HeraHaven AI - NSFW Chat: Tame Roleplay

HeraHaven AI - NSFW Chat: Tame Roleplay
The biggest letdown? My girlfriend kept repeating herself in roleplay — the same lines, the same expressions, again and again.

Image Generation
| Soulkyn | HeraHaven AI |
|---|---|
3.7/5(Good) Convincing images with good personality alignment despite minor eye quirks. | 4/5(Good) Decent, consistent images with minor flaws. |
Soulkyn
There are two ways to generate images:
- In-chat Generation.
- 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.

Soulkyn - In-Chat Image Generation
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.

Soulkyn - Main Image Settings and Options
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.

Soulkyn - Advanced Image Settings
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.
HeraHaven AI
The are two ways to create images:
- Dedicated Image Creator
- In-chat Generation
Dedicated Image Creator
A standalone tool with more options and finer control.
- You can choose a character from the selection or choose your own.
- Enter what you want to see as a prompt, or pick presets.
- Choose the number of images.

HeraHaven AI - Image Generation Feature
Warning: if you leave the results page without adding images to favorites, they’re lost.
In-chat generation
Quick image right there in chat.
- Send “Can I see…” commands with your prompts.

HeraHaven AI - In Chat Image Generation
Quality: Good overall, characters stay true to their personality with only minor AI quirks.
Video Generation
| Soulkyn | HeraHaven AI |
|---|---|
3.5/5(Good) Realistic but betrayed by weird AI movements and image-to-video limitations. | 1/5(Poor) Completely lacks video generation capabilities - a major feature gap. |
Soulkyn
Soulkyn’s video tool acts as an image-to-video converter. Select an image, and the editor opens automatically.

Soulkyn - Select Image to Video
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.

Soulkyn - Video Generation Main Features
Animation Presets
- Preset Selection: Apply up to four presets to guide animation and camera movement.

Soulkyn - Animation Presets

- 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.

Soulkyn - Video Prompt Controls
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.
HeraHaven AI
Looking for those cute AI girlfriend video moments you've seen advertised elsewhere? You won't find them here.
Voice Generation
| Soulkyn | HeraHaven AI |
|---|---|
3/5(Good) Functional but lacking warmth, the voice sounds robotic and emotionally flat. | 3.2/5(Good) Voice is functional but robotic and lacks character-specific traits. |
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.
HeraHaven AI
The voice quality is clear enough to understand, but that's where the positives end.
Zero emotional range. Happy moments, sad moments, flirty banter – everything comes out in the same flat tone.
Safety & Privacy
| Soulkyn | HeraHaven AI |
|---|---|
2.6/5(Good) Claims encryption but lacks proof and keeps data for 6 years after use. | 3.8/5(Good) Strong encryption and discreet billing, but lacks transparency about data retention. |
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.

Soulkyn - Bank Statement
HeraHaven AI
Your chats are protected by the same encryption banks use. Every message, every interaction, every preference - all locked down tight.
HeraHaven stores your chat history to personalize your experience, but they're not crystal clear about how long they keep this data.
They share some of your information with service providers - though they could be more upfront about exactly what and with whom.

HeraHaven AI - Bank Statement
Your statement will show 'herahelp.com'— instead of anything revealing.
