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

Replika vs Thotchat AI

I've spent a full week with both Replika and Thotchat 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.

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.

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.

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.

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.

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.

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.

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.

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…

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.

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.

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.

Video Generation

Replika

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

Thotchat AI

Thotchat AI doesn’t generate videos. If you’re looking for video features, you'll need to look elsewhere.

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.

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.

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.

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.
