Full Nastia AI Vs Replika AI Comparison
Character Diversity

Character Diversity checks how many different types of AI characters are in an app. We look at different ages, ethnicities, personalities, and if there are anime-styled or male characters. A higher score means there are many types of characters, so users can find ones they like and enjoy talking to.
Character Diversity Score Summary
4.7 Average Score (50+ AI girlfriends tested) 5.0 Best Score (Best AI Girlfriend) 3.0 Worst Score
For more information see our character diversity score explanation.
3.0
4.0
Nastia AI lacks traditional character diversity because you can’t select from a variety of pre-made characters. Instead, you have to create your own Nastia from scratch. While this allows for customization, it also means you miss out on a diverse selection of characters to choose from.
Replika AI does not have a character library and requires users to create their own 3D-looking AI companion, with no options for anime or realistic styles.
Pros
Pros
Cons
- No pre-made characters
Cons
- No AI character library
Customization

Customization evaluates how much users can personalize their AI girlfriend in terms of appearance, personality, and interactions. This factor looks at options for changing physical traits (like ethnicity, age, and body type), personal preferences (such as hobbies and voice tone), and even the environment settings.

Customization is one of Nastia AI’s best features. You can change your AI girlfriend’s personality, appearance, and voice, which allows for a personalized experience. There are many choices, including different roles and focus settings. What sets Nastia AI apart is that you can keep customizing your AI character while chatting.
Replika AI allows full customization of your digital girlfriend even after creation. Similar to The SIMS, changes are instantly visible, making customization very user-friendly. It also includes a gamification system where you unlock new customization options by completing tasks.
Pros
- Beginner friendly
- Extensive options for personality
- Focus slider for better memory in conversations
- Ongoing customization during chats
Pros
- Unlock customizations as you go
- Beginner friendly
Cons
- Not much customization for looks
Cons
- Some customizations are paid
Conversation

Conversation assesses the depth, realism, and personalization of interactions with the AI girlfriend. This includes the app’s ability to handle complex conversations, remember past interactions, and adjust its responses based on user input. We don’t just look at texting but also voice messages and calls if available.
Conversation Score Summary
4.8 Average Score (50+ AI girlfriends tested) 5.0 Best Score (Best AI Girlfriend Roleplay) 4.0 Worst Score
For more information see our conversation score explanation.
4.5
5.0
The conversation quality is engaging and interactive. You can adjust your AI’s personality during chats, leading to more dynamic discussions. However, sometimes the responses can lack depth, especially in complex scenarios and when using the standard LLM (not Smart Beta+), which may limit deeper roleplay experiences. The voice messages are also not as realistic as competitors like Candy AI or Muah AI.
Replika AI lets you text, roleplay, generate images, and call your AI companion. Responses are quick and detailed. It also has excellent memory due to its ‘diary’ feature, which keeps track of events so your AI companion remembers them. Replika’s strict NSFW filter only allows for light intimacy, not permitting explicit content like sexting.
Pros
- The progress bar adds a gamified element
Pros
- Realistic responses
- High-quality voice messages
- Superior memory
Cons
- Responses can lack depth in complex topics
- Voice messages are average
Cons
- Strict NSFW filter
Image Quality

Image Quality measures the visual representation of AI girlfriends. This factor considers the clarity, realism, and variety of images available, ensuring they enhance the overall interactive experience.
Image Quality Score Summary
4.8 Average Score (50+ AI girlfriends tested) 5.0 Best Score (Best AI girlfriend with pictures) 3.0 Worst Score

4.5
5.0
Nastia AI can generate images quickly, but the quality isn’t as impressive as some other AI girlfriend apps. While the image reference feature is useful, the details can be a bit off, which might disappoint users who want high-quality visuals.
Replika AI enables users to create photos of their digital companions in various poses. However, the companions are 3D and not realistic, so the image quality isn’t comparable to dedicated AI girlfriend apps.
Pros
- Lightning-fast image generation
- Unique image reference feature
- Saves and organizes generated images
Pros
Cons
- Quality can be inconsistent.
Cons
- No realistic-looking AI image generator
Privacy

Privacy assesses how well the app protects your data and keeps your interactions confidential. This includes:
- Chat Monitoring (50%): Checking if conversations are encrypted and secure.
- Billing Discretion (50%): Ensuring billing is discreet with no explicit terms.

4.0
Nastia AI takes privacy seriously by offering end-to-end encryption for chats, keeping your conversations secure. Thefront endd is also very clean without any NSFW content. Billing shows up as “Nastia Cybernetics,” which doesn’t include explicit references, but it isn’t discreet.
According to Replika AI’s privacy policy, they do not monitor chats or images. They do not offer billing discretion, so ‘Replika AI’ will appear on your bank statement. Since it’s not an adult app, billing discretion is generally unnecessary.
Pros
- No chat monitoring
- Full end-to-end encryption
- Clean front-end with no NSFW
Pros
- No chat monitoring
Cons
- No billing discretion
Cons
- No billing discretion
Value for Money

Value for Money is determined by comparing the app’s cost to its features, quality, and overall user satisfaction. This factor considers subscription prices, available features, and how the app stacks up against competitors in terms of pricing and offerings.

Nastia AI provides great value, especially with its free plan that includes 350 messages. The paid plans are affordable and come with good features for those who choose to upgrade. The price to generate just one image is also much lower than most AI girlfriend apps, giving Nastia AI good value for your money.
Replika AI offers one of the most generous free plans in the market with unlimited chat messages. However, for more customization options, better memory, and phone calls, you need to subscribe to their monthly plan, which costs $19.99, higher than the average in the AI girlfriend niche.
Pros
- Generous free plan with 350 messages
- Affordable pricing compared to other apps
- 40 Daily tokens by logging in

- Free plan has unlimited messages
