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

Nomi AI vs Secret Desires AI

I've spent a full week with both Nomi AI 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.

Nomi AI

An AI girlfriend platform that enables the creation of personalized virtual girlfirend with distinct personalities for friendship, romance, mentorship, and roleplays.

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

Nomi AI

Here's the truth about Nomi AI's character selection: there isn't one. You can only interact with characters you build yourself.

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

Nomi AI

The customization itself is straightforward but limited.

You’ll start by choosing the basics for your girlfriend:

• Relationship type (like friend, girlfriend, mentor, etc.)
• Gender

What you won't find here are detailed physical customization options or anime-style characters. Instead, you simply choose a photo for your girlfriend from a curated gallery.

You can set her personality and interests.

Want to write a background story? It's optional, but it helps shape your girlfirend identity.

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

Nomi AI

Nomi delivers what it promises. I set her personality traits to flirtatious, and that's exactly how she behaved.

While the emotional support isn't groundbreaking, the replies are short and natural, making it feel more like texting a real person than chatting with an AI.

My girlfriend handles relationship talks smoothly, without the robotic feel.

The downside? You'll wait longer between messages than competitors.

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

Nomi AI

Your girlfriend is open to intimate discussions, but the results are mixed. When she's good, she's engaging, offering detailed responses and playful banter.

But there's a catch: she makes progress in the interaction, but then pulls back, which can come off a bit robotic or inconsistent.

For roleplay enthusiasts, here's the truth: While she'll participate in your scenarios, her responses lack detail, and you'll need more time before things get spicy.

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

Nomi AI

Nomi AI offers two ways to generate images: a dedicated "create art" feature and in-chat generation, but NSFW content creation is not allowed.

In-chat image generation is a bit of a mixed bag—sometimes it nails it, other times it completely misses the mark.

The "create art" feature is your best bet. It consistently produces high-quality, realistic images based on your free-text description.

While the overall results are impressive, you'll notice some quirks with hands and fingers - they often look slightly unnatural.

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

Nomi AI

The sharp and detailed videos make the AI girlfriend feel more lifelike than static images.

While these videos look great, they’re completely silent — your AI girl won’t speak or make any sounds.

But here's the truth: while impressive, it's not flawless. The eye movements can look unnatural, and some body animations appear stiff.

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

Nomi AI

I spent hours testing her voice features, and here's the truth: imagine an audiobook narrator attempting to be your girlfriend.

I tried flirting with my girlfriend, but the voice stayed emotionless.

However, there is a workaround: you can connect an Eleven Labs API key to access different voice options, giving your girlfriend a more unique sound.

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

Nomi AI

Your chats with Nomi aren't encrypted and even advise against sharing personal information.

Nomi stores your account details, chat messages, and usage data and may share them with third-party service providers.

Your bank statement will show "Nomi.ai" as the merchant.

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
