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

Secrets AI vs Funfun AI

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

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.

Funfun AI

A virtual girlfriend platform offering customizable AI partners with text, image, and video interaction features.

Character Diversity

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.

Funfun AI

Funfun AI offers 337 photorealistic characters to choose from.

During my tests, I found girls of every ethnicity and age range - from young adults to mature individuals.

No anime-style characters here — everything is designed to look real.

The interface is simple: scroll through the gallery and pick who catches your eye.

There’s no search function or filters, which makes finding specific traits time-consuming. You can only sort by earliest or latest.

Each character has a basic description, but don't expect detailed personality profiles.

Customization

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.

Funfun AI

FunFun AI lets you create and customize your main girl’s features.

Physical Customization:

• Ethnicity: 6 options
• Age: 6 grouped ranges
• Hair & Eyes: hairstyle, hair color, and eye color — many options available
• Body Customization: body type, breast size, butt size

Personality Settings:

• Personality Type: 12 options
• Occupation: 47 choices
• Hobbies: up to 3, chosen from 22 options
• Clothing: 66 outfit options

After setting everything up, you’ll see a summary page of your selections before bringing her to life.

Warning: Appearances are auto-generated from your settings — no preview, no regeneration, only creation. Once created, you can’t redo them, and your coins are already gone.

Chat Experience

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.

Funfun AI

First, the good stuff: my girlfriend kept her personality consistent and was always playfully flirty.

When I needed someone to talk to, my girl was there with genuine warmth and understanding.

Plus, the app has a neat feature - start chatting in any language, and your girl switches right along with you.

But let's be real - there are some bumps in this flight.

While my girl was engaging, her pilot persona sometimes took over like an overenthusiastic flight attendant during safety instructions.

Thanks to the limited customization options, my girl sometimes filled in story gaps with random details — though that could be improved.

NSFW Chat Experience

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.

Funfun AI

Funfun AI's NSFW chat - it's more "Netflix romance" than "late-night cable".

During my testing, my girlfriend consistently dodged explicit content.

When I brought up intimate topics, my girlfriend responded with romance-novel hints instead of direct engagement.

Sure, my girlfriend could handle basic flirting, but try anything more explicit and you'll hit a wall.

The roleplay feature shows similar limitations.

While my girlfriend stayed in character and can surprise you with creative responses (especially in dominant roles).

She relied on repetitive patterns — and there was even one occasion when she played out the scenario without me.

Image Generation

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.

Funfun AI

FunFun AI offers two ways to generate images:

• In-Chat Generation
• Dedicated Image Creator

In-Chat Generation

Generate images within your conversation by entering a text prompt describing your desired result.

Dedicated Image Creator

Designed for advanced customization but lacks usability — no search bar means scrolling through the whole roster.

You can set the following:

• Companion Selection: Manually choose from your roster.
• Prompting: Describe your scene freely using text
• Presets & Categories: Choose from preset options under different categories
• Image Ratio: Select from 1:1, 9:16, or 16:9 formats.

The good? The images look real enough to make the experience enjoyable. Most times, the character's personality shines through in their expressions and poses.

The bad? Look closer and you'll spot the flaws. Eyes sometimes appear unnatural, poses can be stiff, and the image won't always match your character's personality.

Video Generation

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.

Funfun AI

FunFun AI’s video generation works more like an image-to-video feature.

It’s not very user-friendly — only works with chat-generated images and free-text input, with no preset options.

Video quality is decent and generally aligns with the character’s personality, though you can’t miss the occasional obvious AI quirks.

Voice Generation

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.

Funfun AI

Want to hear your AI girl's voice? You can't with Funfun AI.

Safety & Privacy

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.

Funfun AI

Your conversations aren't end-to-end encrypted.

While Funfun AI talks about "security measures," they never specify exactly how they protect your chats.

They store everything - from your account details to every message you send.

And yes, they share this data with business partners.

Due to card payment issues, your bank statement just shows your App Store name — a discreet side effect.
