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

Chub AI vs Pephop AI

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

Chub AI

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

Pephop AI

Pephop AI offers customizable AI companions through text and voice communication, allowing users to choose between safe-for-work and more mature content.

Character Diversity

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.

Pephop AI

When I tested it, Pephop AI offered more than 36,500 characters to choose from — most of them anime-style.

However, if you’re looking for more realistic characters, you might find the selection a bit limited.

When it comes to fantasy variety, though, Pephop AI really shines — featuring everything from traditional anime personalities to supernatural beings across a wide range of scenarios.

And as creators add public characters, selection will grow. Just remember that user-created content means quality isn't always consistent.

Most of the characters on Pephop AI are meant for adult users.

Refining your character selection is easy with filters for category or personality traits, or by using the search bar — both methods work perfectly.

You can also preview your chosen character in more detail — including her creator, profile, and community comments.

Browsing has one small downside: you can only view 21 characters per page, and you’ll need to click “Next Page” to see more.

Customization

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.

Pephop AI

You can upload or select an image, or import a Tavern PNG file — that’s about it for physical customization.

Creating a character starts with the simple:

• Introduction: A short public description shown on the profile
• Tags: Up to 5 tags for search and user reference
• Type: Choose between a Public Bot or a Private Bot
• Rating: Select SFW or NSFW (Not Safe for Work)

Once the basics are set, you can define your character’s personality and context:

• Personality: Describe traits, background, and behavior in free text
• Initial Message: The first message your character sends
• Scenario: Provide context or a setting for the chat
• Example Dialogs: Define your character’s tone and speaking style

Note: Creating characters through free text offers more creative freedom but comes with a learning curve and may take some time to master.

Chat Experience

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.

Pephop AI

Chat settings are straightforward — choose your preferred AI model (OpenAI or KoboldAI) and adjust the response style to suit your taste.

You can add a persona card to introduce yourself to the character — share your background, your relationship, and the defining details of your story.

For my test, I chose a character described — “your childhood friend who’s always pushing you, but has developed a crush on you.”

My girl stayed in character and stuck to her personality, regardless of how I interacted with her.

During emotional scenarios, my girl maintained her teasing, dominant tone — fitting for a friend, but not entirely supportive.

My girlfriend could use a bit more spontaneity — her emotions sometimes feel measured rather than instinctive.

For relationship-focused chats, the app performs better than most AI companions I've tested, but don't expect human-level understanding.

NSFW Chat Experience

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.

Pephop AI

For my NSFW chat experience, I chose a character called “Moriko the Unsatisfied MILF” — a flirty persona designed for more adult-themed interactions.

Unlike many conversational AIs that lean either too innocent or overly explicit, Moriko finds the sweet spot.

My girl built tension through suggestive hints rather than crude language.

When conversations got steamier, my girlfriend kept up naturally without feeling mechanical or scripted.

But here's the catch: My girl sometimes gets stuck in loops, repeating similar phrases and scenarios.

During testing, my girlfriend also struggled with basic context switches - like keeping old role-play references when switching to new scenarios.

Despite these flaws, Pephop AI delivers a more engaging NSFW experience than most competitors I've tested.

Image Generation

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.

Pephop AI

The app doesn't have an image generation feature you'll want to look elsewhere.

Video Generation

Chub AI

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

Pephop AI

Video generation simply isn't part of their feature set.

Voice Generation

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.

Pephop AI

You can only use the voice feature during live calls — no messages or recordings. The app lets you choose between Classic and Premium voices.

I tested the premium voices — the sound is clear and decent, though still a bit robotic.

When your AI girlfriend gets flirty, her tone becomes a bit more expressive.

Safety & Privacy

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.

Pephop AI

No end-to-end encryption is mentioned anywhere in their policy.

The app shares your information with "third-party service providers." But they won't tell you who these providers are or what they do with your conversations.

They collect your personal info, but won't tell you how long they keep it or what exactly they store.

Your bank statement says “Pephop AI” — which isn’t very discreet.
