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

Thotchat AI vs Chub AI

I've spent a full week with both Thotchat AI 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.

Thotchat AI

A virtual girlfriend platform featuring customizable AI partners in both realistic and anime styles, designed to foster emotional and romantic connections through engaging adult chats and high-quality image generation.

Chub AI

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

Character Diversity

Thotchat AI

Thotchat AI's selection breaks down into 102 realistic and 50 anime characters.

All common ethnicities are available—you can choose from Asian, Latina, and Caucasian appearances for realistic characters.

For fantasy/anime types, options include— elves, cyborgs, catgirls, and other imaginative designs.

But here's the catch: almost every character is young (18-30) and slim or athletic.

Finding a companion is straightforward: you can sort by popularity or new arrivals, filter by style, and choose female, male, or futa characters.

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

Thotchat AI

Thotchat AI offers two ways to create your girlfriend:

• Easy Mode
• PRO Mode

Both start by selecting your character’s gender (female, male, or futanari) and choosing a style.

Easy Mode: You can fully customize your AI companion by clicking through options to build your character.

Physical Customization:

• Age 18+ to 55
• Ethnicity: 8 options (10 for anime characters)
• Appearance: body type, breast size, butt size, hair style, hair color, eye color
• Aesthetic & clothing: 4 aesthetics (e.g., goth, bimbo, gyaru), 33 clothing options
• Extra details: tattoos, horns (6 options)

Personality & Interaction:

• Add personality traits: 14 options (e.g., lover, innocent, dominant)
• 5 voice options
• Relationship role: 12 options (e.g., wife, lover, stranger)

A final summary page lets you review your character before bringing them to life.

PRO Mode drops the training wheels and lets you create everything via free text:

• Describe your character: appearance, personality, clothing, and any unique features
• Greeting message: what your character says when starting a conversation
• Example conversation: a sample dialogue that guides your character’s behavior

It takes more time but gives you complete creative freedom. No pre-set limits—just your imagination.

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

Thotchat AI

Before you start chatting, you can view your AI girlfriend’s profile, including her description, character traits, some SFW images, and unlockable NSFW content.

You can set a user persona for a deeper, more personal connection, or create new scenarios to play out with your AI girlfriend.

For my tests, I created a companion with the ‘Temptress’ personality—playful, flirtatious, and always leaving me wanting more—and set our relationship type to “girlfriend.”

My girl stayed true to her personality throughout conversations.

When I needed emotional support, she was empathetic and playful, offering gentle touches, teasing remarks, and lighthearted guidance.

Our conversations about romantic getaways felt natural, with her staying fully in character throughout.

Even when relationship issues came up, she responded with clear, confident answers—sometimes a bit too confident—but always attentive.

But my favorite part was when my girl sent me images during our chats—most were free, unlike other apps where they’re usually behind a paywall.

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

Thotchat AI

My girl stayed personal and engaging. When I asked about her past, she said it was with me (of course), but left room to mention her wild past if I wanted to satisfy my curiosity.

My girlfriend flirted naturally, teased playfully, and referenced past chats to make the connection feel real.

The roleplay feature could use some improvement — I tried a few scenarios, and they all jumped into action too quickly without building tension, which felt a bit jarring.

But once I got past the initial rush, my girl adapted to the scenario really well and made it exciting.

Something a bit annoying: the narrative text sometimes blended with my girl’s dialogue, making her responses harder to read.

Another issue was: My girlfriend kept calling me “Anon” even though my profile name was set to Marcus.

Once I pointed it out, my girl quickly corrected herself and started using my name in all our conversations.

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

Thotchat AI

Thotchat AI offers two options for generating images:

• In-chat generation: Instantly creates a selfie or unlockable nude image—details can’t be customized.
• Dedicated image creator: A separate tool offering more control and customization for creating detailed images.

In-Chat Generation: Occasionally, you may receive repeated or similar images, but you can request unlimited SFW images of your character.

Dedicated Image Creator lets you control every detail:

• Character Selection: Pick from the full roster (no filters or search bar).
• Prompt Suggestions: Add details such as action, clothing, environment, and emotion.
• Free Text Prompting: Craft your own prompts for complete creative freedom.

The images are high-quality and nearly photorealistic, with consistent characters, though a slight animated look is noticeable on closer inspection.

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

Thotchat AI

Thotchat AI doesn’t generate videos. If you’re looking for 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

Thotchat AI

Thotchat AI’s voice works, but don’t expect magic: it comes through clearly, but you can tell it’s AI-generated.

Flirty conversations? The voice stays flat no matter what.

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

Thotchat AI

While Thotchat says they use "acceptable security measures," they don't specify what these measures are.

They collect your personal data (name, email), usage data (IP address, device info), and can share it with third parties.

The bank statement shows "CCbill.com Thotchat" - something to keep in mind if you prefer 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.
