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

FantasyGF vs Secret Desires AI

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

FantasyGF

AI girlfriend platform offering customizable partners with chat, image generation, and personalized video features.

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.

Character Diversity

FantasyGF

The app gives you 80 characters to choose from - split evenly between realistic and anime-styled companions. The diversity is basic. You get three ethnicities and characters aged 18-30.

The platform keeps it simple with just one filter: toggle between realistic or anime characters.

Want more AI girls? Here's a trick: Follow active creators on the platform. Their public character collections unlock dozens of additional companions you won't find in the main roster.

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.

Customization

FantasyGF

FantasyGF lets you customize everything from looks to personality.

The appearance editor is straightforward:

• Choose between anime or realistic style
• Pick ethnicity
• Age (18-60)
• Adjust physical features

You can modify eye color, hairstyle, body type, and proportions. Nothing groundbreaking, but it works well and offers enough options to create a distinct character.

Personality settings come in two flavors: 12 preset personalities for quick setup, or custom creation for more control.

You'll also define your relationship status, her occupation, and hobbies. The preset options are particularly useful if you're new to AI companions and aren't sure where to start.

While the customization system isn't revolutionary, it's practical and user-friendly. Some options feel limited, but there's enough depth to create a companion that matches your preferences.

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.

Chat Experience

FantasyGF

During chatting, my AI girl maintained her innocent character consistently, even when conversations turned romantic. Instead of explicit responses, she'd suggest things like "Let's take it slow with a massage tonight."

The chat feels personal at first. Your AI girlfriend remembers your conversations, asks about your day, and shows genuine interest in your life. She handles emotional topics well and responds to relationship concerns while keeping her distinct personality traits intact.

But here's the reality check: the longer you chat, the more artificial it feels. The AI's responses become predictably nice, even when faced with rudeness, and often too long-winded.

Also, my chat history got cut off after extended conversations, and I couldn't access earlier messages (still can't).

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.

NSFW Chat Experience

FantasyGF

The AI girls start strong - they flirt, they play, they each have their own personality. My AI girlfriend played her "innocent" role well at first. When I suggested some spicy chat, she didn't jump right in. She took her time, stayed true to her character. Nice touch.

But here's the catch: push the NSFW talk too far, and the whole thing falls apart. That shy, innocent personality? Gone.

Suddenly you're talking to a completely different character. And the longer you chat, the less natural it feels. The AI gets too eager to please, too chatty, too... artificial.

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.

Image Generation

FantasyGF

The images are high-quality and consistent. My girl looked the same across different pictures, and the overall visual quality matches what you'd expect from premium AI generators.

When I asked for specific poses or expressions, the AI delivered clear, detailed results.

But be aware! The platform defaults to NSFW content, even with basic requests like "standing pose" or "friendly smile." There are also occasional visual glitches, as you can see on the pictures (visible bra under breasts).

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.

Video Generation

FantasyGF

You can also create videos of your AI girl, and they look good. They are smooth, realistic, and your AI girlfriend looks exactly like she does in her photos.

But while these videos look great, they're silent. Your AI girl won't speak or make any sounds. It's purely visual interaction.

Now, the elephant in the room - cost. One video nearly wiped out my entire monthly token allowance. Yes, you read that right. So while the technology is impressive, you'll need to decide if spending a large chunk of your tokens on a single video is worth it.

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.

Voice Generation

FantasyGF

The voice quality is decent, but you'll notice a robotic undertone. With only 6 voices to choose from, your options are limited.

I tried setting up an Asian character, but couldn't find a voice that matched the personality - none of the options had the right accent or tone.

While you'll hear slight variations in expression between different voices, they're not distinct enough to create unique characters. The bottom line? It works, but don't expect anything groundbreaking.

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

Safety & Privacy

FantasyGF

The app stores all your chat messages and shares them with third parties - they're transparent about this in their policy. Chat encryption? They don't mention it. This means your conversations might not be as private as you'd like.

Your bank statement will show "Aichatee" - a discrete touch that keeps your AI relationship private from prying eyes. But that's where the privacy features end.

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
