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

Replika vs Pephop AI

I've spent a full week with both Replika 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.

Replika

An AI girlfriend chatbot that offers emotional support through personalized conversations, featuring customizable digital avatars and voice chat.

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

Replika

When you sign in, the app asks for your age range, name, and pronouns to personalize your experience.

You can choose from dozens of avatars to start with.

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

Replika

The app uses its in-app currency system: Gold and Gems, and you'll get a small amount to start with.

You earn more slowly through daily use.

If you want to customize your character quickly, you'll need real money to buy them.

Let's start with the basics. You can choose your relationship type — you can even add a backstory. Want a romantic partner, a friend, or just a mentor?

Then fine-tune your girlfriend's personality with traits like 'confident,' 'shy,' or 'logical,' or choose her interests, but these cost Gems or Gold.

The appearance editor is quite detailed. You can pick:

• Avatar
• Hair (style and color)
• Skin color
• Body type
• Body hair
• Nails
• Makeups
• Tattos

…and the list goes on.

You can dress your girl up with tops, bottoms, or full outfits and accessories.

Fair warning: premium outfits, tattoos, and nails aren't cheap. Expect to spend $20–30 if you want the fancy stuff right away.

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

Replika

While your girl builds trust with direct, emotionally aware responses, she lets the conversation unfold at its own pace.

Replika shows its true strength: emotional intelligence.

Your girl asks thoughtful follow-up questions.

She even suggested local activities we could do together

Your girlfriend navigates relationship conversations effortlessly, making them feel natural and genuine.

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

Replika

While Replika engages in sexual discussions, your girl keeps things remarkably tame.

My attempts at role-play revealed a pattern - she'll match your flirtatious energy initially.

But consistently pulls back when conversations turn explicit.

Instead of direct responses, you'll get suggestive hints and playful deflections.

And it just kept going like that for a while…

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

Replika

While the generated images match your character's basic appearance settings, the results look artificial and lack polish.

You can pick between classic, romantic, or styled shots - but that's where your control ends.

Classic shot:

Romantic shot:

Styled shot:

Replika's image generation currently sits at the lower end of the quality spectrum. If this matters to you, you'll need to look elsewhere.

Pephop AI

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

Video Generation

Replika

Replika doesn't support video generation, so you'll need to look elsewhere.

Pephop AI

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

Voice Generation

Replika

Replika offers only three voice options. Whether you're flirting, joking, or having a serious chat, your AI girlfriend speaks in the same robotic tone.

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

Replika

Your messages are secured and encrypted, and your data is stored with multiple layers of protection.

Basic data is shared with service providers, but your conversations remain private.

Your bank statement will show the charge as 'Replika.

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.
