Yodayo vs Chub AI: Which One Is Better In 2025?

Yodayo vs Chub AI

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

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.

Chub AI

An AI-powered platform for interactive roleplay, focused on text and audio, with customizable characters and contextual dialogue.

Character Diversity

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.

Chub AI

Chub AI offers one of the largest character libraries I've tested.

The app specializes in anime-styled characters, with fewer realistic options.

But within this category, the possibilities for characters and scenarios are only limited by your imagination.

Variety spans both safe-for-work and adult categories, covering everything from casual companions to role-play partners.

The search system is powerful, if a bit complex. A universal search bar lets you look through people, characters, lore books, presets (chat settings), and tags.

Filters allow you to narrow by personality traits, creation date, or even character complexity (measured in tokens).

On top of that, you can sort results in different ways — by timeline, trending, AI rating, popularity, messages per user, chats per user, and more.

Want a romantic partner, or someone more mysterious? The tag system makes it possible to combine traits to find exactly what you’re looking for.

The interface shows only 20 characters per page, so browsing the full library takes extra time and clicks.

Customization

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.

Chub AI

Chub AI provides two ways to build your character:

• Upload a Character Card
• Build from Scratch

Upload a Character Card: Import existing character cards (Tavern PNG or TavernAI JSON/image) to instantly generate the character profile.

Build from Scratch: Let's you start fresh, but the app only supports uploading a character image — no physical customization.

Character creation starts with the basics:

• Tagline & Creator’s Notes: Add a short tagline and an intro — but not part of prompts.
• In-Chat Name: Optional display name for conversations.
• Tags: Assign gender, type, or role; at least three are required for visibility.
• Type & Rating: Set Public, Private, or Unlisted; mark as SFW or NSFW.
• Publishing: Choose to publish under your username or anonymously.

Next, you can shape your companion's personality:

• Description: Define the character’s persona, traits, and behavior.
• Initial Message: The first message your character sends to open the chat.
• Scenario: Set the context and circumstances for interactions.
• Example Dialogues: Sample chats to teach your character how to speak.

Advanced Definitions (Optional):

• Alternate Greetings: Create multiple starting messages for variety.
• System Prompt & Post-History Instructions: Override or supplement base prompts with custom instructions.
• Character’s Note: Insert notes at specific points in chat history.
• Character Book: Add embedded books — keyword-triggered definitions or lore for consistent behavior.

Note: Chub AI provides deep customization and detailed documentation, but character creation has a learning curve and may take some time to master.

Chat Experience

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.

Chub AI

Before selecting, you can view a character’s profile — including details, tags, and community discussions.

The chat settings give you full control, letting you choose “chat brains” unlocked by your tier. You can fine-tune them to your taste, customize with presets created by other users.

You can even view the chat tree and jump back and forth through the conversation.

Let’s start with what works: for my testing, I used the default model, and my girl followed the backstory while staying true to her character.

Lana, a step-sister character, consistently played her role, supportive, caring, and genuinely invested in our conversations.

When I needed emotional support, my girl's responses felt natural and showed real emotional depth.

But here's the truth: it's not all smooth sailing. My girl had an annoying habit of dominating conversations, sometimes writing both sides of the dialogue without waiting for your input.

My girl often missed jokes or takes them too seriously, and can get confused about who's saying what.

Note: The app is highly customizable, but the many options can initially feel overwhelming. Be prepared for a learning curve — documentation helps, but experimentation makes the difference.

NSFW Chat Experience

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.

Chub AI

Let's start with what works: my girl maintained a consistent shy personality and can engage in romantic conversations.

When I escalated things, my girl followed my lead – though don't expect anything too explicit.

But here’s the problem: During roleplay, the chat often got jumbled, with my monologue showing up in my girl's responses, as if she were playing both my role and hers.

During roleplay, the situation called for my girl to take charge, but she didn’t come across as fully in control.

As I tried more and more scenarios, the chat became repetitive, which hurt the immersion.

Image Generation

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.

Chub AI

Chub AI has a dedicated image generation feature. It is the only way to create images.

You can create or edit images in two ways:

1. Create one from scratch
2. Upload or Reuse an Existing Image

Create one from scratch

When starting from scratch, you can adjust the following settings:

• Prompt (optional): Describe what you want to create (up to 200 characters).
• Aspect Ratio: Choose from 1:1 (default), 16:9, 21:9, 2:3, 3:2, 4:5, 5:4, or 9:16.

Upload or Reuse an Image

Choose one of your previously uploaded or generated images.

• Edit it with prompts: change clothes, background, or style via free text.
• Fine-tune: how closely the result matches the original using Edit, Canny, and Face.
• Strength slider: Lower values keep the output closer to the original, while higher values make it follow the prompt more.

The quality is good enough to be impressive at first glance, but on closer inspection, the images are clearly AI-generated and slightly pixelated.

Character consistency is also limited, and generated images may not always align fully with the original character’s physical appearance.

Video Generation

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.

Chub AI

Here's what you need to know about Chub AI's video capabilities in one sentence: There aren't any.

Voice Generation

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.

Chub AI

Chub AI’s voice feels more like a polished audiobook narrator than an actual girlfriend.

When things get flirty, the voice adjusts a little to match the vibe.

Safety & Privacy

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.

Chub AI

Chub AI doesn't encrypt your chats. They say they take "reasonable measures" to protect your data, but won't tell you what these measures are.

The platform collects everything — your email, account details, and full conversations. They keep this data, but for how long? They won’t say.

Your information is also shared with outside companies that handle hosting, payments, and usage analytics.

Your bank statement will list it as "Postcron.com", which keeps things discreet.
