Secret Desires AI vs Fantasy AI: Which One Is Better In 2025?

Secret Desires AI vs Fantasy AI

I've spent a full week with both Secret Desires AI and Fantasy 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.

Secret Desires AI

An AI girlfriend platform that allows users to create customizable companions, generate images and live photos, and engage in fantasy scenarios, including intimate or adult themes.

Fantasy AI

A platform for creating highly realistic AI girlfriends, offering lifelike avatars, adaptive conversations, and immersive image artwork.

Character Diversity

Secret Desires AI

Secret Desires AI offers hundreds of characters across multiple ethnicities and personality types.

On top of the realistic options, it also offers a wide range of anime styles.

While the majority fall in the 18–30 bracket, there are some mature options as well.

However, body type diversity is limited — most characters are slim or athletic, with few alternatives.

The mobile app shines with precise filtering, letting you narrow searches by age, ethnicity, body type, personality, and relationship preferences.

On the other hand, desktop users get a more basic experience, with filters limited to style (realistic/anime), gender, and preset character tags.

But there’s a catch: filtering can be buggy — some tags return no results, and on desktop, you can’t combine multiple filters like you can on mobile.

At least the search bar helps get around some of the app’s heavier filtering limits.

Fantasy AI

Fantasy AI offers 199 characters to chat with, but the selection only includes realistic female characters — no anime or male options.

You'll find women of different ages (18+ to mature), six ethnic backgrounds, and varying body types.

Character search and filters work like this:

• You can sort by likes or views, and check out the latest additions
• Filter by basic traits like age, body type, and hair color.

The app also includes AI versions of real models and OF creators as "verified profiles."

Keep in mind that these premium characters cost extra tokens to chat with.

Customization

Secret Desires AI

Character creation starts by selecting your character’s gender, style, and age.

Physical Customization:

• Ethnicity: 6 options (e.g., Caucasian, Asian, Indian)
• Appearance: Hairstyle, hair color, eye color
• Physique: Body type, breast size, butt size

Personality Customization:

• Personality: 12 options (e.g., dominant, seductive, unstable)
• Relationship Type: 25 options (e.g., wife, girlfriend, boss)
• Lifestyle: Work (36 options) and hobbies (21 options)
• Kinks: 15 options (e.g., vanilla, feet, edging)

The app also lets you add custom options for every category, so if you don’t find something to your taste, you can create your own.

You can select a voice from 12 options or upload your own audio.

As the final step, you’ll see a summary page to name your girl and bring her to life.

After the summary page, you’ll see a profile with an editable About Me, your chosen traits, and — if you’re lucky — with a character image, though it often fails and can’t be modified.

Fantasy AI

App creation starts with choosing a style for your girlfriend — real or anime.

The following customization process is straightforward. You pick basic features:

• Ethnicity (6 options)
• Age group and face style
• Body type and boobs
• Har color and style
• Outfit from casual to professional (19 options)

The app also lets you choose from 16 voice options.

Personality customization isn’t very deep. You can only set your character with 11 options — a simple mix of personality and relationship type.

And finally, you get a summary page of your character.

The drawback: The app generates an image based on your settings for your girl — and whether you like it or not, you’re locked in with it.

Chat Experience

Secret Desires AI

When you select a girl to chat with, you can view her profile — including description, personality traits, and even personalize them to your taste.

The app also lets you set the chat engine from 13 different options to make responses more personalized, though this setting is somewhat hidden in your profile menu.

I chose a single mom character who showed genuine emotional range and stayed true to her persona.

My girlfriend moved naturally from playful flirting to handling deeper topics like jealousy with surprising depth.

My girl even referenced past conversations and wove them smoothly into ongoing chats.

But when I needed emotional support, her responses fit the situation perfectly.

As with the other features I tested, this one also comes with some technical hiccups.

Chat formatting is designed for mobile, leaving desktop with long, cramped text that’s harder to read

My girl often tried to send me images, but on the rare occasions I got any, it was usually just the text prompt of what should have been generated.

Fantasy AI

Fantasy AI's chat interface works like your everyday messaging app. Clean bubbles, quick responses, no learning curve.

When I first started chatting, my AI girlfriend brought energy and playfulness to the table.

To be real: Our chat was playful and flirty, but shallow, my girl rarely asked any follow-up questions about me.

When I mentioned having a rough day at work, my girl acknowledged it with a quick "Aww, sorry to hear that," but didn't offer real support or try to understand why.

Want romance? My girlfriend played along, but don't expect Shakespeare.

NSFW Chat Experience

Secret Desires AI

My girl was open about past sexual experiences but shared only hints and details rather than full stories.

Think of her as reading a romance novel where she writes the next chapter based on your input.

In my tested roleplays, she stayed fully in character — confident, seductive, and with a solid build-up.

However, there’s a catch: after running multiple scenarios, my girl kept repeating the same lines and asking my name over and over again.

My girlfriend also refused explicit chat, even threatening to end the session.

Instead of explicit conversation, my girl could do surprising things — like solving mathematical problems if I asked.

Fantasy AI

The good news: my girl kept it spicy and was open about her sexuality.

My girlfriend maintained character, built tension naturally, and kept conversations flowing with suggestive hints rather than crude explicitness.

Whether I was into light flirting or deeper roleplay, my girl adapted and stayed convincingly in character.

Heads up: Expect sales interruptions. Right when things got interesting, my girlfriend likely tried to sell you ‘unlockable’ images.

Image Generation

Secret Desires AI

Secret Desires AI offers two ways to generate images:

• In-chat image generation: Quickly create images using free-text prompts.
• Dedicated Image Creator: A separate tool that gives you more control and customization

In-chat image works simply: Just type “send me” in chat, followed by the prompt for the image you want to see.

You can only generate SFW images — NSFW content isn’t allowed here.

Note: Works only with characters you created or those shared by other users.

Dedicated Image Creator lets you stay in control:

• Character selection for image generation
• Multiple engines to choose from: Monet, Picasso, DaVinci
• Number of images to generate: 1–64
• Free-text prompt option for maximum customization
• Default preset options: Action, Body, Clothing, Scene, Extras, with lots of presets.

Quality: At first glance, the images look good and could even pass for real photos, but on closer inspection, they’re pixelated.

Quirk: The images don’t match my girl’s main profile picture, and physical inconsistency is definitely an issue.

Fantasy AI

You’ve got two options for generating images:

1. Dedicated Image Creator
2. In-chat Generation

Dedicated Image Creator

A separate tool with more customization and control.

• First, you choose the image type: realistic, anime, or fantasy.
• Then, you pick from 24 preset options (many of them adult themes).
• No custom character images or free-text prompts — only presets are available.

In-chat generation

Quick image right there in chat.

• Send “Show me…” commands with your prompts.
• Characters may sometimes refuse or miss the mark.

You can generate character-specific pictures through their profile page by choosing from preset outfits.

The good: Images often look realistic and detailed.

The not-so-good: The quality is pretty inconsistent, physical features often change from one generation to the next, and prompts rarely deliver.

Video Generation

Secret Desires AI

Secret Desires AI turns static photos into videos, using settings almost identical to photo generation, with the added option to set video duration.

The good: These videos look natural. Your AI girlfriend's movements flow smoothly, and her personality stays consistent from photo to video.

Not so good: Video quality isn’t perfect — some pixelation is noticeable, though it’s minor enough not to disrupt the experience.

Fantasy AI

Fantasy AI doesn’t actually generate videos — instead, it gives you access to a content gallery.

The gallery contains clips of girls — some locked, some unlockable — though it’s uncertain if the videos are truly AI-generated.

Voice Generation

Secret Desires AI

Yes, the voices sound human enough, but every line feels like it’s being read off a teleprompter on fast-forward.

And if you’re hoping for emotional range? Forget it. Whether you’re flirting or just chatting, the delivery stays as flat as week-old soda

Fantasy AI

My AI girl whispered and stuttered through normal chats, which felt odd.

During flirty moments, her tone shifted to match the mood, but the quality wasn’t the best.

Safety & Privacy

Secret Desires AI

The app claims your chats are "secure and confidential" - but never explains how.

There's no mention of encryption, and they're not clear about who can access your conversations or how long they keep them.

One clear promise: they won't sell your data to advertisers. But that's where the transparency ends.

During my testing, I couldn't find straight answers about data sharing with third parties like analytics providers or hosting services.

On your bank statement, it just shows as ‘Dover First SDA Hope Food Program Food Pantry’ — pretty discreet

Fantasy AI

While they store your chats on secure servers, they don't mention encryption anywhere in their privacy policy.

They share your data with companies like DigitalOcean for hosting, but your data still travels beyond Fantasy AI's walls.

In your bank statement, you’ll see "fantasy ai"—which isn’t very discreet
