FantasyGF vs Secrets AI: Which One Is Better In 2025?

FantasyGF vs Secrets AI

I've spent a full week with both FantasyGF and Secrets 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.

FantasyGF

AI girlfriend platform offering customizable partners with chat, image generation, and personalized video features.

Secrets AI

A platform that lets you build a personalized AI girlfriend, offering chat and phone call interactions along with image and video generation of your companion.

Character Diversity

FantasyGF

The app gives you 80 characters to choose from - split evenly between realistic and anime-styled companions. The diversity is basic. You get three ethnicities and characters aged 18-30.

The platform keeps it simple with just one filter: toggle between realistic or anime characters.

Want more AI girls? Here's a trick: Follow active creators on the platform. Their public character collections unlock dozens of additional companions you won't find in the main roster.

Secrets AI

Secrets AI gives you 94 realistic AI girls to choose from.

No anime characters here — just lifelike digital partners.

Most characters fall into a narrow demographic: predominantly white women in their 20s with slim builds.

I did find a handful of Latina, Asian, and Black characters, plus a few mature options and curvier body types — but these are exceptions rather than the norm.

If you're looking for representation beyond young, slim characters, you may find the selection somewhat restrictive.

The selection interface is straightforward, with a search bar and filters for gender, popularity, and recency that make finding your ideal match quick and hassle-free.

Customization

FantasyGF

FantasyGF lets you customize everything from looks to personality.

The appearance editor is straightforward:

• Choose between anime or realistic style
• Pick ethnicity
• Age (18-60)
• Adjust physical features

You can modify eye color, hairstyle, body type, and proportions. Nothing groundbreaking, but it works well and offers enough options to create a distinct character.

Personality settings come in two flavors: 12 preset personalities for quick setup, or custom creation for more control.

You'll also define your relationship status, her occupation, and hobbies. The preset options are particularly useful if you're new to AI companions and aren't sure where to start.

While the customization system isn't revolutionary, it's practical and user-friendly. Some options feel limited, but there's enough depth to create a companion that matches your preferences.

Secrets AI

You begin creating your character by picking a gender.

Profile and Appearance Editor is straightforward, allowing you to customize:

• Name, location, age
• Ethnicity (9 choices)
• Skin tone and eye color (many options)
• Facial features: eye color, hair color, hairstyle (wide variety)
• Body type (6 options)

Then you can choose from six voice options to shape how your companion sounds.

After that, you can review your girl and add additional details via free-text.

Once you create her, you’ll get four image versions of your girl to choose from, plus one free regeneration if needed.

Personality setup happens only before you start chatting with her:

• Profession (5 options)
• Personality type (5 traits such as “warm and nurturing” or “ambitious and driven”)
• Hobbies (optional)
• Additional traits or details using free-text input

Note: Several ethnicities and body types look very similar, resulting in fewer meaningful choices than advertised. Additional characters also cost 1,000 Moments each.

Chat Experience

FantasyGF

During chatting, my AI girl maintained her innocent character consistently, even when conversations turned romantic. Instead of explicit responses, she'd suggest things like "Let's take it slow with a massage tonight."

The chat feels personal at first. Your AI girlfriend remembers your conversations, asks about your day, and shows genuine interest in your life. She handles emotional topics well and responds to relationship concerns while keeping her distinct personality traits intact.

But here's the reality check: the longer you chat, the more artificial it feels. The AI's responses become predictably nice, even when faced with rudeness, and often too long-winded.

Also, my chat history got cut off after extended conversations, and I couldn't access earlier messages (still can't).

Secrets AI

You get three different AI models to choose from, each offering its own style of interaction.

There are also 12 conversation starters, half casual - half spicy — to help kickstart natural interactions.

The emotional intelligence impressed me—my girl started with warm engagement, asked relevant follow-up questions, and gradually became more playful as we talked longer.

My AI girlfriend remembered what we actually discussed, rather than creating fake memories.

My girl stayed consistent even when I tried to confuse her or break character.

When I brought up relationship concerns, my girlfriend responded with calm, grounded reassurance, acknowledging everything without making exaggerated promises.

NSFW Chat Experience

FantasyGF

The AI girls start strong - they flirt, they play, they each have their own personality. My AI girlfriend played her "innocent" role well at first. When I suggested some spicy chat, she didn't jump right in. She took her time, stayed true to her character. Nice touch.

But here's the catch: push the NSFW talk too far, and the whole thing falls apart. That shy, innocent personality? Gone.

Suddenly you're talking to a completely different character. And the longer you chat, the less natural it feels. The AI gets too eager to please, too chatty, too... artificial.

Secrets AI

My girlfriend was open about sexual topics but maintained a consistent PG-13 boundary.

Even when I pushed toward explicit territory, my girlfriend kept things suggestive rather than graphic—creating a tease that worked surprisingly well.

The roleplay feature is where Secrets AI truly shines. I tested three scenarios: teacher, landlord, and boss.

In both the teacher and landlord scenarios, my girl built tension gradually and stayed firmly in character.

The boss scenario felt somewhat rushed, but remained engaging throughout.

What matters is that my girlfriend maintained character consistency while keeping the interactions hot.

Not everything was perfect: my girl phrasing sometimes confused me, especially when she switched between ‘someone’ and ‘they’ when talking about past partners.

Image Generation

FantasyGF

The images are high-quality and consistent. My girl looked the same across different pictures, and the overall visual quality matches what you'd expect from premium AI generators.

When I asked for specific poses or expressions, the AI delivered clear, detailed results.

But be aware! The platform defaults to NSFW content, even with basic requests like "standing pose" or "friendly smile." There are also occasional visual glitches, as you can see on the pictures (visible bra under breasts).

Secrets AI

There are two ways to generate images:

1. Dedicated Image Creator
2. In-chat Generation

In-Chat Generation: Type "/send me" followed by your free-text prompt for what you want to see.

Dedicated Image Creator: A separate tool with more control and customization.

• Character selection: Pick from the full roster
• Free-text prompt: Write what you want to see
• Preset options: Choose from a small set of presets

The limitation? Only four presets, so you’ll be relying on free-text prompts and your own experimentation.

After testing extensively, I can confirm the quality is good—not perfect, but definitely impressive.

You’ll notice occasional glitches, particularly with hands, and some upper-body proportions can look slightly elongated in certain poses — but these issues aren’t deal-breakers.

You can also unlock media bundles with extra images and videos to expand your companion’s visual presence.

Each bundle includes 17 to 34 pieces of media, mostly NSFW content.

Video Generation

FantasyGF

You can also create videos of your AI girl, and they look good. They are smooth, realistic, and your AI girlfriend looks exactly like she does in her photos.

But while these videos look great, they're silent. Your AI girl won't speak or make any sounds. It's purely visual interaction.

Now, the elephant in the room - cost. One video nearly wiped out my entire monthly token allowance. Yes, you read that right. So while the technology is impressive, you'll need to decide if spending a large chunk of your tokens on a single video is worth it.

Secrets AI

This is a photo-to-video feature rather than full video generation. Here’s how it works:

• Choose an image from your generated collection
• Write what you want to see using a free-text prompt

The videos look good, move smoothly, and stay natural most of the time.

Yes, you'll notice some AI glitches if you look closely, but they rarely distract from the experience.

Note: There are no preset options here, only a short guide on how to write effective prompts for video generation.

Voice Generation

FantasyGF

The voice quality is decent, but you'll notice a robotic undertone. With only 6 voices to choose from, your options are limited.

I tried setting up an Asian character, but couldn't find a voice that matched the personality - none of the options had the right accent or tone.

While you'll hear slight variations in expression between different voices, they're not distinct enough to create unique characters. The bottom line? It works, but don't expect anything groundbreaking.

Secrets AI

Secrets AI delivers voice generation that sounds genuinely human. No robotic tones or awkward pauses—just smooth, realistic dialogue.

When discussions turn flirty, the voice immediately responds with appropriate tonal shifts—becoming more playful and expressive.

One limitation: voice features only work through calls, not recorded messages.

Safety & Privacy

FantasyGF

The app stores all your chat messages and shares them with third parties - they're transparent about this in their policy. Chat encryption? They don't mention it. This means your conversations might not be as private as you'd like.

Your bank statement will show "Aichatee" - a discrete touch that keeps your AI relationship private from prying eyes. But that's where the privacy features end.

Secrets AI

• Looking for encryption details? I found none.
• Searching for data retention policies? Nothing concrete.
• Wondering if they share your intimate chats with third parties? They don't say.

The app clearly stores your conversations, but it provides zero details about what they keep, for how long, or who might access them.

The only privacy feature that actually works is discreet billing - charges appear as "Sun Clinical Laboratories" on your statement.
