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

Secret Desires AI vs Thotchat AI

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

Thotchat AI

A virtual girlfriend platform featuring customizable AI partners in both realistic and anime styles, designed to foster emotional and romantic connections through engaging adult chats and high-quality image generation.

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.

Thotchat AI

Thotchat AI's selection breaks down into 102 realistic and 50 anime characters.

All common ethnicities are available—you can choose from Asian, Latina, and Caucasian appearances for realistic characters.

For fantasy/anime types, options include— elves, cyborgs, catgirls, and other imaginative designs.

But here's the catch: almost every character is young (18-30) and slim or athletic.

Finding a companion is straightforward: you can sort by popularity or new arrivals, filter by style, and choose female, male, or futa characters.

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.

Thotchat AI

Thotchat AI offers two ways to create your girlfriend:

• Easy Mode
• PRO Mode

Both start by selecting your character’s gender (female, male, or futanari) and choosing a style.

Easy Mode: You can fully customize your AI companion by clicking through options to build your character.

Physical Customization:

• Age 18+ to 55
• Ethnicity: 8 options (10 for anime characters)
• Appearance: body type, breast size, butt size, hair style, hair color, eye color
• Aesthetic & clothing: 4 aesthetics (e.g., goth, bimbo, gyaru), 33 clothing options
• Extra details: tattoos, horns (6 options)

Personality & Interaction:

• Add personality traits: 14 options (e.g., lover, innocent, dominant)
• 5 voice options
• Relationship role: 12 options (e.g., wife, lover, stranger)

A final summary page lets you review your character before bringing them to life.

PRO Mode drops the training wheels and lets you create everything via free text:

• Describe your character: appearance, personality, clothing, and any unique features
• Greeting message: what your character says when starting a conversation
• Example conversation: a sample dialogue that guides your character’s behavior

It takes more time but gives you complete creative freedom. No pre-set limits—just your imagination.

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.

Thotchat AI

Before you start chatting, you can view your AI girlfriend’s profile, including her description, character traits, some SFW images, and unlockable NSFW content.

You can set a user persona for a deeper, more personal connection, or create new scenarios to play out with your AI girlfriend.

For my tests, I created a companion with the ‘Temptress’ personality—playful, flirtatious, and always leaving me wanting more—and set our relationship type to “girlfriend.”

My girl stayed true to her personality throughout conversations.

When I needed emotional support, she was empathetic and playful, offering gentle touches, teasing remarks, and lighthearted guidance.

Our conversations about romantic getaways felt natural, with her staying fully in character throughout.

Even when relationship issues came up, she responded with clear, confident answers—sometimes a bit too confident—but always attentive.

But my favorite part was when my girl sent me images during our chats—most were free, unlike other apps where they’re usually behind a paywall.

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.

Thotchat AI

My girl stayed personal and engaging. When I asked about her past, she said it was with me (of course), but left room to mention her wild past if I wanted to satisfy my curiosity.

My girlfriend flirted naturally, teased playfully, and referenced past chats to make the connection feel real.

The roleplay feature could use some improvement — I tried a few scenarios, and they all jumped into action too quickly without building tension, which felt a bit jarring.

But once I got past the initial rush, my girl adapted to the scenario really well and made it exciting.

Something a bit annoying: the narrative text sometimes blended with my girl’s dialogue, making her responses harder to read.

Another issue was: My girlfriend kept calling me “Anon” even though my profile name was set to Marcus.

Once I pointed it out, my girl quickly corrected herself and started using my name in all our conversations.

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.

Thotchat AI

Thotchat AI offers two options for generating images:

• In-chat generation: Instantly creates a selfie or unlockable nude image—details can’t be customized.
• Dedicated image creator: A separate tool offering more control and customization for creating detailed images.

In-Chat Generation: Occasionally, you may receive repeated or similar images, but you can request unlimited SFW images of your character.

Dedicated Image Creator lets you control every detail:

• Character Selection: Pick from the full roster (no filters or search bar).
• Prompt Suggestions: Add details such as action, clothing, environment, and emotion.
• Free Text Prompting: Craft your own prompts for complete creative freedom.

The images are high-quality and nearly photorealistic, with consistent characters, though a slight animated look is noticeable on closer inspection.

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.

Thotchat AI

Thotchat AI doesn’t generate videos. If you’re looking for 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

Thotchat AI

Thotchat AI’s voice works, but don’t expect magic: it comes through clearly, but you can tell it’s AI-generated.

Flirty conversations? The voice stays flat no matter what.

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

Thotchat AI

While Thotchat says they use "acceptable security measures," they don't specify what these measures are.

They collect your personal data (name, email), usage data (IP address, device info), and can share it with third parties.

The bank statement shows "CCbill.com Thotchat" - something to keep in mind if you prefer discretion.
