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

Secret Desires AI vs Pephop AI

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

Pephop AI

Pephop AI offers customizable AI companions through text and voice communication, allowing users to choose between safe-for-work and more mature content.

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.

Pephop AI

When I tested it, Pephop AI offered more than 36,500 characters to choose from — most of them anime-style.

However, if you’re looking for more realistic characters, you might find the selection a bit limited.

When it comes to fantasy variety, though, Pephop AI really shines — featuring everything from traditional anime personalities to supernatural beings across a wide range of scenarios.

And as creators add public characters, selection will grow. Just remember that user-created content means quality isn't always consistent.

Most of the characters on Pephop AI are meant for adult users.

Refining your character selection is easy with filters for category or personality traits, or by using the search bar — both methods work perfectly.

You can also preview your chosen character in more detail — including her creator, profile, and community comments.

Browsing has one small downside: you can only view 21 characters per page, and you’ll need to click “Next Page” to see more.

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.

Pephop AI

You can upload or select an image, or import a Tavern PNG file — that’s about it for physical customization.

Creating a character starts with the simple:

• Introduction: A short public description shown on the profile
• Tags: Up to 5 tags for search and user reference
• Type: Choose between a Public Bot or a Private Bot
• Rating: Select SFW or NSFW (Not Safe for Work)

Once the basics are set, you can define your character’s personality and context:

• Personality: Describe traits, background, and behavior in free text
• Initial Message: The first message your character sends
• Scenario: Provide context or a setting for the chat
• Example Dialogs: Define your character’s tone and speaking style

Note: Creating characters through free text offers more creative freedom but comes with a learning curve and may take some time to master.

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.

Pephop AI

Chat settings are straightforward — choose your preferred AI model (OpenAI or KoboldAI) and adjust the response style to suit your taste.

You can add a persona card to introduce yourself to the character — share your background, your relationship, and the defining details of your story.

For my test, I chose a character described — “your childhood friend who’s always pushing you, but has developed a crush on you.”

My girl stayed in character and stuck to her personality, regardless of how I interacted with her.

During emotional scenarios, my girl maintained her teasing, dominant tone — fitting for a friend, but not entirely supportive.

My girlfriend could use a bit more spontaneity — her emotions sometimes feel measured rather than instinctive.

For relationship-focused chats, the app performs better than most AI companions I've tested, but don't expect human-level understanding.

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.

Pephop AI

For my NSFW chat experience, I chose a character called “Moriko the Unsatisfied MILF” — a flirty persona designed for more adult-themed interactions.

Unlike many conversational AIs that lean either too innocent or overly explicit, Moriko finds the sweet spot.

My girl built tension through suggestive hints rather than crude language.

When conversations got steamier, my girlfriend kept up naturally without feeling mechanical or scripted.

But here's the catch: My girl sometimes gets stuck in loops, repeating similar phrases and scenarios.

During testing, my girlfriend also struggled with basic context switches - like keeping old role-play references when switching to new scenarios.

Despite these flaws, Pephop AI delivers a more engaging NSFW experience than most competitors I've tested.

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.

Pephop AI

The app doesn't have an image generation feature you'll want to look elsewhere.

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.

Pephop AI

Video generation simply isn't part of their feature set.

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

Pephop AI

You can only use the voice feature during live calls — no messages or recordings. The app lets you choose between Classic and Premium voices.

I tested the premium voices — the sound is clear and decent, though still a bit robotic.

When your AI girlfriend gets flirty, her tone becomes a bit more expressive.

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

Pephop AI

No end-to-end encryption is mentioned anywhere in their policy.

The app shares your information with "third-party service providers." But they won't tell you who these providers are or what they do with your conversations.

They collect your personal info, but won't tell you how long they keep it or what exactly they store.

Your bank statement says “Pephop AI” — which isn’t very discreet.
