PolyBuzz vs Sakura AI: Which One Is Better In 2025?

PolyBuzz vs Sakura AI

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

Sakura AI

A character-based AI interaction platform where you can chat intimately with custom AI personalities and explore a growing community of unique characters.

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.

Sakura AI

Sakura AI offers a huge collection of anime-style AI girlfriends.

The search system is straightforward—you can filter by character type (male, female, non-binary, lesbian, etc.).

When you're looking for particular character types, you can also use keywords and toggle NSFW content on/off.

The library expands regularly as users add their custom-made characters to the public collection.

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.

Sakura AI

Instead of tweaking physical features, you'll craft your character through storytelling in freeform text.

Basic customization lets you upload an image or generate one from text.

You can set gender and voice and even add a background image to your chat.

But that's not where Sakura AI shines. The real customization happens through free-text inputs.

You write your character's description, personality, and scenario from scratch and can also fine-tune how your AI responds through Model Instructions.

The platform includes a practical tagging system (Tsundere, Vampire, Non-binary, etc.) to help categorize your creation.

However, if you're looking for detailed physical customization like choosing eye color or body type, you won't find it here.

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.

Sakura AI

I tested my girl in a role as my ex-girlfriend, and the girl is warm, stays in character, and keeps conversations flowing.

When I needed emotional support, my girls offered it with a bit of flirtation, and she played along naturally.

Whether my girlfriend talks about relationship concerns, her responses feel genuine and thoughtful.

The app includes a mature content warning, so you can expect adult conversations when appropriate.

The chat interface needs improvement, sometimes it's hard to distinguish narrative messages from my girl's.

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.

Sakura AI

During my testing, my girlfriend kept recycling the same flirty responses, even when I tried different approaches.

The biggest letdown? Her roleplay feature. My girl switches back to being my "ex-girlfriend" and starts repeating the same lines.

I tested this multiple times - same result.

The immersion breaks faster than you can say "mood killer."

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.

Sakura AI

The images are clean and well-drawn, matching what you'd expect from modern anime art.

You can't control exactly what pictures you get. The app generates random images right in your chat conversations.

If you want to direct every detail of your character's appearance, you might find the randomness frustrating.

Video Generation

PolyBuzz

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

Sakura AI

Sakura doesn't offer any video generation, 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.

Sakura AI

After spending hours testing different conversations, I can tell you, the voice is clear but lacks any real personality.

Think of it this way: Whether I'm flirting, joking, or having a serious chat, Sakura's voice stays flat.

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."

Sakura AI

While Sakura claims to use advanced encryption, I couldn't find this explicitly stated in their policy. They also store your conversations and personal information. They share data with third parties.

On top of that, payment is more complicated than their competitors, as it requires using multiple platforms and connecting them together.

Your bank statement is safe - payments appear as "GANKPTELTD".
