PolyBuzz vs Joi Ai: Which One Is Better In 2025?

PolyBuzz vs Joi Ai

I've spent a full week with both PolyBuzz and Joi 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.

PolyBuzz

AI chatbot platform for personalized conversations and role-play, featuring unrestricted chats, customizable traits, AI image generation, and dynamic storylines.

Joi Ai

An AI-powered virtual girlfriend platform offering adult chats and intimate services, tailored for mature audiences.

Character Diversity

PolyBuzz

PolyBuzz AI offers a massive, diverse character selection.

From anime companions to life coaches, the app covers a wide range of character types you might want to interact with.

Their "Popular Series" feature lets you chat with AI versions of characters from Oscar-winning films, anime shows, and even girl groups.

For those seeking specific interactions, the app offers specialized options like AI Girlfriend, Virtual Assistant, or 'Ask AI' for custom queries.

Finding your ideal companion is simple: use filters for gender, genre (anime, sci-fi, fantasy), or search by specific keywords.

The search results show in a single column — making it easy to find your character, but not ideal for quick browsing.

The app doesn’t save search filters when leaving Character Discovery, forcing you to reapply them each time, which can be frustrating.

Joi Ai

Joi AI offers solid character selections — you'll find everything from college students to mature partners, spanning six ethnicities.

The roster keeps growing daily as users create public characters.

Want fantasy companions? They're here. During my tests, I found elves, orcs, and angels alongside anime-styled characters.

Character search works but is basic — filter by creator, gender, age, or tags like fantasy and sexual orientation, or use the search bar.

Customization

PolyBuzz

To create your own AI girl, PolyBuzz gives you two options:

• Build from scratch
• Import an existing character via a character card

1. Build from scratch

Create anime-style avatars using the app’s image generation feature, or upload your own—physical customization isn’t available.

Flexible personality builder customization, but all details must be typed manually—no presets.

• Name & Gender
• Intro & First Greeting: a brief description and the opening message of your character
• Backstory: a detailed backstory for your character
• Dialogue Style
• Tags: add keywords to help others find your character

And finally choose from 51 female voices, and set who can see your character.

2. Import an existing character via a character card

Already using Character AI or Tavern? PolyBuzz lets you import your existing character cards. Just upload the file, and you’re ready to go.

Joi Ai

Joi AI offers two ways to design your perfect AI partner:

• Choose from presets
• Write unique prompts (free text)

Both methods start by selecting your character’s gender and preferred style.

1. The preset system is straightforward. Your AI companion is fully customizable — including appearance, personality, and behavior.

Physical Customization:

• Age and ethnicity: Options include White, Asian, Latina, Black, and more.
• Body customization: Height, physique, breasts, and butt — each with 5 adjustable options.
• Hair and eyes: Choose hairstyle, hair color, and eye color.

Personality Settings:

• 12 personality types with adjustable sliders (or create your own from scratch)
• Sexual orientation: 4 options, from straight to queer
• Chat style: 4 modes, including default, deep roleplay, and creative
• Occupation and relationship dynamic
• Set specific kinks and preferences

2. Use freeform prompts to design your AI companion — shaping everything from personality to appearance.

But here's what they don't tell you: while your first character comes with the premium subscription, extra companions cost 1000 Neurons (about $20) each.

Chat Experience

PolyBuzz

PolyBuzz lets you customize how your AI girlfriend talks and behaves—the language model you choose shapes the dialogue style— for my testing, I used the standard model.

You can also adjust user persona settings to make your girl's responses more relevant.

During my tests, my girl maintained consistent personality traits and could handle everything from casual jokes to emotional conversations.

While testing deeper conversations, I noticed my girlfriend's genuine-feeling support and attention to detail.

It’s not perfect—some replies can be a bit predictable, like the classic tropical escape—but it’s still more engaging than most AI companions.

The app offers engaging features like reply suggestions and Heart Whisper (your character’s thoughts), but only for an additional cost on top of the premium subscription.

Joi Ai

Before you choose a character to chat with, you can view her profile, bio, and images — though most images require an extra purchase to unlock.

The catch? You start at Level 1 and can only chat with characters at your level — unless you spend Neurons on gifts or early unlocks.

About the chat: Joi AI offers flexible responses — you can choose from six different LLM models, each with a unique interaction style to match your vibe.

The chat began playful and flirty with my girlfriend — no robot-like responses there, just natural, brief exchanges that felt surprisingly human.

She was good at relationship talks and providing emotional support.

But her romantic responses, while warm, didn’t go very deep.

Here are the deal-breakers: you’re limited to 115 characters per message — about the length of this sentence.

Also, Joi AI constantly upsells — my girlfriend randomly sent unlockable images every few messages. Needless to say, that got annoying fast.

NSFW Chat Experience

PolyBuzz

Here's what actually works: My girlfriend didn't rush into explicit content. Instead, she built natural tension through conversation.

When I asked for a personal story, my girl playfully flipped the question back to me—just like a teasing girlfriend would, staying true to her character.

No generic responses, no awkward pivots - just smooth, contextual exchanges that felt surprisingly real.

The role-play feature worked as advertised. I tested multiple scenarios, from mild flirting to more intimate situations.

My girl stayed in character throughout each session and adapted to my inputs without breaking immersion.

While not perfect—my girl sometimes got my gender wrong—she handled adult conversations more naturally than most competitors I’ve tested.

Joi Ai

I tested Joi AI's NSFW chat extensively, and it's not what you might expect from an AI girlfriend app.

The reality? My girlfriend kept strict boundaries around adult content. She flirted, but conversations felt mechanical and often broke immersion.

During my tests, my girl referenced non-existent features like "your posted photos," showing clear problems in the chat system.

Sometimes my girlfriend surprised me with bold messages —like "Imagine having your face between my legs 😳"— but they often felt random and out of context.

As for roleplay? I tried multiple character profiles - each one either avoided or completely rejected roleplay scenarios.

Joi AI may not be your top choice if you're seeking genuine NSFW conversations.

Image Generation

PolyBuzz

PolyBuzz’s image generation gives you two ways to create:

• Normal Mode – solo character art.
• Ship Them Mode – pairing two characters in one scene.

Normal Mode: Create a single character image using built-in presets or an uploaded reference.

Start with your basic settings:

• Prompt: Type a text prompt to describe your character
• Aspect ratios: Choose from 9:16, 1:1, or 16:9
• Detail controls: Adjust stylization and complexity sliders

Once your base is set, refine your character visually using presets:

• Subjects & styles: Built-in or uploaded characters; styles like Gorgeous, Urban, Fantasy, Cyberpunk, etc.
• Customization: Change age, skin tone, expressions (smile, crying, shy, laughing), gestures (victory, heart, salute).
• Poses & accessories: Standing, sitting, kneeling; add chokers, earrings, rings, wings, tails.
• Visuals: Adjust composition and lighting (close-up, low-angle, backlighting).

Result:

Ship them: This mode works the same way but creates two characters in one image, which is great for couples, friends, or interactive scenes.

Start with your dual prompts and settings:

• Prompts: Separate fields for Character A, Character B, and an integration prompt to describe how they interact
• Settings: Identical to Normal Mode

Refine settings with presets:

• Characters: Choose from built-in characters or upload your own, then customize age, expressions (smile, crying, shy, angry), skin tone, and accessories.
• Integration: Fine-tune the overall scene with style options, poses, lighting, and other visual elements.

Result:

The images look great and are mostly accurate, but it’s essentially a general image generator—you need to re-upload specific characters each time.

Note: Only anime-style art is supported, and any nudity—even mild, like extra cleavage, violates community standards.

Joi Ai

Joi AI offers a dedicated image generation feature that gives you control over details like:

• Character selection
• Prompts and negative prompts for AI-generated images
• 50 Poses — ranging from explicit to artistic
• Number of images and resolution

The premium plan includes 50 image generations — but using them for specific characters costs extra Neurons, which isn’t mentioned upfront.

The image quality? Realistic enough to recognize what you're going for, but AI artifacts give it away.

Faces often appear slightly off, with eyes not perfectly aligned, and objects in the scene can come out distorted.

In testing different prompts, I found the results hit-or-miss — sometimes surprisingly accurate, other times way off.

Video Generation

PolyBuzz

If seeing your AI girlfriend in video form is important, you must look elsewhere.

Joi Ai

Joi AI’s video generation is nearly identical to photo creation — same prompts and characters, but with 5 adult poses and 19 styles, including Simpsons, GTA, photorealistic, and more.

The same trick applies to video generation too — the premium plan includes 5 “free” videos, but choosing specific characters costs extra Neurons.

The videos look good with smooth animations and solid quality.

Voice Generation

PolyBuzz

The voices sound natural, match character personalities, and adapt during conversations.

As the conversation progressed, my AI girl's voice could shift with the context and grow more flirty depending on the dialogue flow.

Joi Ai

Joi AI lacks voice capabilities — if you want to hear your girlfriend’s voice, you’ll need to try another app.

Privacy

PolyBuzz

PolyBuzz gets this right with end-to-end encryption on all conversations. No one - not even PolyBuzz staff - can access your chat content.

Your messages aren’t stored on their servers, but PolyBuzz isn’t super clear about what else they collect. The Google Play Store even notes that some of your data might be shared.

When you check your bank statement, you'll see "Singularity Mutual Ent" - nothing that screams "AI companion."

Joi Ai

There’s no mention of end-to-end encryption or other security measures for chat messages. Your conversations and personal information are stored on Joi Ai's servers.

While they promise never to sell this data, they do share it with service providers for analytics and improvements.

Good news? Your credit card statement shows up as "edenai.world" - keeping your AI relationship discreet.
