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

Secret Desires AI vs Funfun AI

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

Funfun AI

A virtual girlfriend platform offering customizable AI partners with text, image, and video interaction features.

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.

Funfun AI

Funfun AI offers 337 photorealistic characters to choose from.

During my tests, I found girls of every ethnicity and age range - from young adults to mature individuals.

No anime-style characters here — everything is designed to look real.

The interface is simple: scroll through the gallery and pick who catches your eye.

There’s no search function or filters, which makes finding specific traits time-consuming. You can only sort by earliest or latest.

Each character has a basic description, but don't expect detailed personality profiles.

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.

Funfun AI

FunFun AI lets you create and customize your main girl’s features.

Physical Customization:

• Ethnicity: 6 options
• Age: 6 grouped ranges
• Hair & Eyes: hairstyle, hair color, and eye color — many options available
• Body Customization: body type, breast size, butt size

Personality Settings:

• Personality Type: 12 options
• Occupation: 47 choices
• Hobbies: up to 3, chosen from 22 options
• Clothing: 66 outfit options

After setting everything up, you’ll see a summary page of your selections before bringing her to life.

Warning: Appearances are auto-generated from your settings — no preview, no regeneration, only creation. Once created, you can’t redo them, and your coins are already gone.

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.

Funfun AI

First, the good stuff: my girlfriend kept her personality consistent and was always playfully flirty.

When I needed someone to talk to, my girl was there with genuine warmth and understanding.

Plus, the app has a neat feature - start chatting in any language, and your girl switches right along with you.

But let's be real - there are some bumps in this flight.

While my girl was engaging, her pilot persona sometimes took over like an overenthusiastic flight attendant during safety instructions.

Thanks to the limited customization options, my girl sometimes filled in story gaps with random details — though that could be improved.

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.

Funfun AI

Funfun AI's NSFW chat - it's more "Netflix romance" than "late-night cable".

During my testing, my girlfriend consistently dodged explicit content.

When I brought up intimate topics, my girlfriend responded with romance-novel hints instead of direct engagement.

Sure, my girlfriend could handle basic flirting, but try anything more explicit and you'll hit a wall.

The roleplay feature shows similar limitations.

While my girlfriend stayed in character and can surprise you with creative responses (especially in dominant roles).

She relied on repetitive patterns — and there was even one occasion when she played out the scenario without me.

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.

Funfun AI

FunFun AI offers two ways to generate images:

• In-Chat Generation
• Dedicated Image Creator

In-Chat Generation

Generate images within your conversation by entering a text prompt describing your desired result.

Dedicated Image Creator

Designed for advanced customization but lacks usability — no search bar means scrolling through the whole roster.

You can set the following:

• Companion Selection: Manually choose from your roster.
• Prompting: Describe your scene freely using text
• Presets & Categories: Choose from preset options under different categories
• Image Ratio: Select from 1:1, 9:16, or 16:9 formats.

The good? The images look real enough to make the experience enjoyable. Most times, the character's personality shines through in their expressions and poses.

The bad? Look closer and you'll spot the flaws. Eyes sometimes appear unnatural, poses can be stiff, and the image won't always match your character's personality.

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.

Funfun AI

FunFun AI’s video generation works more like an image-to-video feature.

It’s not very user-friendly — only works with chat-generated images and free-text input, with no preset options.

Video quality is decent and generally aligns with the character’s personality, though you can’t miss the occasional obvious AI quirks.

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

Funfun AI

Want to hear your AI girl's voice? You can't with Funfun AI.

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

Funfun AI

Your conversations aren't end-to-end encrypted.

While Funfun AI talks about "security measures," they never specify exactly how they protect your chats.

They store everything - from your account details to every message you send.

And yes, they share this data with business partners.

Due to card payment issues, your bank statement just shows your App Store name — a discreet side effect.
