PolyBuzz vs Yodayo: Which One Is Better In 2025?

PolyBuzz vs Yodayo

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

Yodayo

An AI-powered platform that converts text prompts into anime-style artwork, offering character customization, community sharing features, and interactive character chat capabilities for anime enthusiasts.

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.

Yodayo

Yodayo offers thousands of characters to choose from.

Most are anime-style or fantasy-based, with a smaller selection of realistic characters available.

I found everything from traditional anime personalities to fantasy creatures like orcs and cyborgs.

The search system is practical. You can filter characters:

• Filter by traits or categories
• Browse: Popular, Trending, New, etc.
• Search using keywords.

This helps narrow down options quickly, though the process could be overwhelming for first-time users due to the sheer number of choices.

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.

Yodayo

First, let's address the elephant in the room: Yodayo doesn't offer physical appearance settings. Instead, it focuses entirely on personality and interaction — you can only upload an image of your character.

You get two creation paths:

• Quick AI-assisted setup through YoPilot,
• Detailed manual customization.

Manual mode gives you more control - you write the character:

• Description
• Persona
• First message
• Scenario

Pilot keeps it simple: type in a name, description, and gender, and the AI does the heavy lifting.

You can choose voice presets (including celebrity voices) or upload your recordings.

The platform features hashtags and a tagging system that helps categorize your character.

The real customization happens in the advanced settings:

• Different LLM models
• System preset (such as roleplay, spicy roleplay, humor, etc.)
• Model parameters.

You can also customize image generation with many fine-tuning and preset options.

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.

Yodayo

The platform lets you pick from multiple AI models - from free options to premium ones like GPT-4 and Claude.

I tested Nephra 12b (a free model) and found the conversations flow naturally, without the robotic feel you might expect.

The flirtation level adjusts based on your interaction style, though it can sometimes get quite forward.

During testing, my girl handled both light chats and deeper conversations well, showing solid emotional awareness and offering comfort when needed.

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.

Yodayo

My girlfriend handled sexual topics with surprising authenticity. She maintained her character and adapted to different scenarios without breaking immersion.

The role-play experience is solid. My girl stayed in character and followed conversation threads naturally, whether you're keeping things light and flirty or exploring deeper fantasies.

But she's not perfect - sometimes her responses can feel repetitive during longer sessions.

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.

Yodayo

Yodayo offers two ways to do it.

The In-chat image generation- ask for a picture, and a settings window will appear:

• What to generate (yourself, your face, or the last message)
• A custom prompt using free text
• The image engine and fine-tuning settings
• Canvas size, and more

The result? You'll get natural-looking photos that match your character, but occasional inconsistencies.

One limitation is that changing the pre-generated prompts can be difficult for new users and may lead to unwanted results.

The separate image tool offers more control, with detailed prompt explanations and precise settings.

While powerful, it comes with a catch: you can't generate images of your specific AI companion here. You'll need to use the in-chat generator for that.

Video Generation

PolyBuzz

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

Yodayo

The app doesn't generate videos. Period. If you're after a more lifelike experience with video features, you'll need to look elsewhere.

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.

Yodayo

The voice sounds robotic and flat - imagine Siri from 2011, not a modern AI girlfriend.

During my testing, even flirty conversations felt mechanical, with only slight tone variations that barely register.

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."

Yodayo

Your messages are locked down with bank-grade encryption. This means nobody, not even Yodayo's team, can peek at your private conversations.

But here's what you should know: Yodayo keeps your messages and shares some data with companies like Google Analytics.

When you check your bank statement, you'll see "Moescape AI" which apparently is new brand name for Yodayo. But what it meas for you? It means you can forget about the discretion.
