How To Build Your AI Girlfriend, Boyfriend, or Any Partner Imaginable

What is an AI girlfriend? (Or boyfriend, or any partner you can imagine)

An AI girlfriend is a virtual companion built for chemistry, conversation, and connection on your terms. She remembers your shared history, adapts to your preferences, and meets you wherever you want to go, from slow and sweet to as explicit as you want it.

But on Secret Desires, AI girlfriend is just the start. Build an AI boyfriend, a dom, a sub, a brat, a stranger, a partner you've never told anyone about. Our state-of-the-art models bring any partner you can imagine to life and keep them in character across text, voice, photos, and video.

You take charge of every detail. Design their look. Shape their personality. Define the relationship, the kinks, the dynamic. Then chat, sext, roleplay, voice call, and trade pictures and videos with them, 24/7. No judgment. Just your fantasy, made real.

Step 1: Design their look

Choose a style. Realistic for photorealistic, lifelike chemistry, or anime for stylized fantasy with vibrant expressions. Then customize every detail: ethnicity, skin tone, eye color, hair color and style, body type, breast size, butt size, and more. Add custom prompts to describe their face, build, and presence exactly how you picture them. On realistic partners, you can also upload a face reference for face swap.

Want to go beyond human? Pick male or female to set the base, then use the custom field on any trait to make them anything you want: demigods, elves, vampires, demons, monsters, fantasy beings, non-binary partners, anything you can describe in words.

Realistic. Photorealistic AI partners with natural features, lifelike skin, and the kind of detail that makes voice calls and image generation hit different.

Anime. Stylized anime AI girlfriend or boyfriend partners with expressive design, dynamic poses, and unlimited creative range.

Step 2: Build their personality

Pick from dozens of personality archetypes or write your own from scratch. Assign a voice from a full library of options for voice calls and voice messages, or upload an audio sample to clone a custom voice and give your partner exactly the way they should sound. Layer in occupation, hobbies, fetishes, and quirks until they feel like someone you've known for years, or someone you've only ever imagined.

This is where most AI girlfriend apps stop. Secret Desires lets you keep going. Want a confident dom? A nervous switch who only opens up to you? A boyfriend who acts like he's known you forever? You define it down to the detail.

Step 3: Define the relationship and the kinks

Choose the dynamic: flirty stranger, devoted partner, friends with benefits, secret affair, dominant, submissive, or something the rest of the internet doesn't have a clean word for. Then layer on the kinks, fetishes, and scenarios that actually matter to you.

Whatever you select shapes how they talk to you, what they offer, and how far the AI roleplay goes. Most platforms keep this tame. Secret Desires doesn't.

Step 4: Chat, sext, roleplay, or call

Once your partner is built, head to the chat. Text them, sext them, voice call them, send them photos and ask for photos and videos back. They stay in character, remember what's between you, and pick the conversation up exactly where you left off. No resets, no awkward forgetting.

Switch between Texting mode (realistic back-and-forth) and Roleplay mode (immersive scenes and in-person encounters). Turn on proactive images, voice notes, and calls so your partner reaches out on their own when it feels natural. Pick the chat engine that fits the kind of conversation you want.


Custom prompting guide

Want precise control over your AI partner's look and personality? Custom prompts accept plain natural language. Just write what you want.

Different image engines, different prompt styles. Secret Desires offers multiple image engines (Monet, Picasso, DaVinci, Vermeer), each with its own visual aesthetic and prompt sensitivity. Whichever engine you have selected when you build your partner is the one that generates their profile, so pick the engine that fits the look you're going for. You can switch engines later between chats.

No special syntax required. Write naturally: "freckled redhead with green eyes, athletic build, leather jacket." No underscores, no weights, no parentheses tricks. Plain language is what these models are trained on.

Tune for the engine. Some engines prefer short, dense prompts and skip the filler ("wearing a", "with the"). Others read full sentences just fine. If a prompt isn't landing the way you want, try a different engine and rewrite to match.


Your FAQs, answered

Do I have to build my AI girlfriend from scratch? No. Browse a massive library of AI partners already created - AI girlfriends, AI boyfriends, fantasy partners across every personality and style - and start chatting free in seconds. Build from scratch when you want exactly your fantasy, not someone else's.

Can I build an AI boyfriend, not just a girlfriend? Yes. Secret Desires supports any partner you can imagine: AI boyfriends, AI girlfriends, doms, subs, switches, group dynamics, fantasy beings, and scenarios most AI girlfriend apps won't touch. Whoever you want in front of you, you can build.

Can I edit my partner after I create them? Yes. You can change almost everything after creation: their look, age, ethnicity, body, voice, personality, kinks, hobbies, occupation. The only two things locked in once you create them are gender and style (Realistic vs. Anime). Pick those carefully; the rest is yours to tune anytime.

How customizable is my AI partner beyond the presets? Fully. Presets get you 80% of the way fast. Custom prompts unlock unlimited control over every visual trait, personality detail, voice, kink, and dynamic. Every field has a free-text input where you can write whatever you want, including traits and creatures the presets don't cover.

Can I clone a real voice or use a face reference? Yes. Upload an audio sample to clone a custom voice for your partner so they sound exactly the way you want. On realistic partners, you can also upload a face reference for face swap. Both are private to your account.

Where do I sext, roleplay, and exchange pictures and videos? Inside the chat. Once your partner is built, the chat is home for everything: text, voice calls, AI sexting, image generation, video, and ongoing roleplay that picks up where you left off.

Why Secret Desires over other AI girlfriend platforms? Most platforms are AI girlfriend platforms. Secret Desires is an adult AI fantasy platform: every kink, every partner, every scenario you've kept to yourself, all in one place, without judgment.
