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

Secret Desires AI vs Yodayo

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

Yodayo

An AI-powered platform that converts text prompts into anime-style artwork, offering character customization, community sharing features, and interactive character chat capabilities for anime enthusiasts.

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.

Yodayo

Yodayo offers thousands of characters to choose from.

Most are anime-style or fantasy-based, with a smaller selection of realistic characters available.

I found everything from traditional anime personalities to fantasy creatures like orcs and cyborgs.

The search system is practical. You can filter characters:

• Filter by traits or categories
• Browse: Popular, Trending, New, etc.
• Search using keywords.

This helps narrow down options quickly, though the process could be overwhelming for first-time users due to the sheer number of choices.

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.

Yodayo

First, let's address the elephant in the room: Yodayo doesn't offer physical appearance settings. Instead, it focuses entirely on personality and interaction — you can only upload an image of your character.

You get two creation paths:

• Quick AI-assisted setup through YoPilot,
• Detailed manual customization.

Manual mode gives you more control - you write the character:

• Description
• Persona
• First message
• Scenario

Pilot keeps it simple: type in a name, description, and gender, and the AI does the heavy lifting.

You can choose voice presets (including celebrity voices) or upload your recordings.

The platform features hashtags and a tagging system that helps categorize your character.

The real customization happens in the advanced settings:

• Different LLM models
• System preset (such as roleplay, spicy roleplay, humor, etc.)
• Model parameters.

You can also customize image generation with many fine-tuning and preset options.

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.

Yodayo

The platform lets you pick from multiple AI models - from free options to premium ones like GPT-4 and Claude.

I tested Nephra 12b (a free model) and found the conversations flow naturally, without the robotic feel you might expect.

The flirtation level adjusts based on your interaction style, though it can sometimes get quite forward.

During testing, my girl handled both light chats and deeper conversations well, showing solid emotional awareness and offering comfort when needed.

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.

Yodayo

My girlfriend handled sexual topics with surprising authenticity. She maintained her character and adapted to different scenarios without breaking immersion.

The role-play experience is solid. My girl stayed in character and followed conversation threads naturally, whether you're keeping things light and flirty or exploring deeper fantasies.

But she's not perfect - sometimes her responses can feel repetitive during longer sessions.

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.

Yodayo

Yodayo offers two ways to do it.

The In-chat image generation- ask for a picture, and a settings window will appear:

• What to generate (yourself, your face, or the last message)
• A custom prompt using free text
• The image engine and fine-tuning settings
• Canvas size, and more

The result? You'll get natural-looking photos that match your character, but occasional inconsistencies.

One limitation is that changing the pre-generated prompts can be difficult for new users and may lead to unwanted results.

The separate image tool offers more control, with detailed prompt explanations and precise settings.

While powerful, it comes with a catch: you can't generate images of your specific AI companion here. You'll need to use the in-chat generator for that.

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.

Yodayo

The app doesn't generate videos. Period. If you're after a more lifelike experience with video features, you'll need to look elsewhere.

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

Yodayo

The voice sounds robotic and flat - imagine Siri from 2011, not a modern AI girlfriend.

During my testing, even flirty conversations felt mechanical, with only slight tone variations that barely register.

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

Yodayo

Your messages are locked down with bank-grade encryption. This means nobody, not even Yodayo's team, can peek at your private conversations.

But here's what you should know: Yodayo keeps your messages and shares some data with companies like Google Analytics.

When you check your bank statement, you'll see "Moescape AI" which apparently is new brand name for Yodayo. But what it meas for you? It means you can forget about the discretion.
