Full Character AI Vs Replika AI Comparison

Character Diversity

Question Mark Tooltip Icon

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

Character AI is a major AI chatbot platform with a vast collection of characters. It’s great for roleplay and also features AI therapists, lawyers, financial advisors, and even teachers for learning new languages. Character AI has a strict NSFW filter, so it doesn’t include intimate characters.

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

  • Huge collection of AI characters

Pros


Cons

  • Lacks NSFW characters

Cons

  • No AI character library

Customization

Question Mark Tooltip Icon

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 Score Summary

4.7 Average Score (50+ AI girlfriends tested) 5.0 Best Score (Best AI Girl Generator) 3.0 Worst Score

Character AI requires users to create their own AI characters, providing limitless customization options.

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

  • Advanced customization

Pros

  • Unlock customizations as you go
  • Beginner friendly

Cons

  • Requires prompt engineering skills

Cons

  • Some customizations are paid

Conversation

Question Mark Tooltip Icon

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

Character AI has professional prompt engineers, resulting in high-quality characters that are excellent for roleplay. While some characters, like those for RPGs, can send in-chat images, you cannot request them. Character AI doesn’t offer phone calls but recently added voice messages, allowing users to record and replicate their own voices, a feature most AI girlfriend apps lack.

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

  • Superior roleplay
  • High-quality chatbots
  • Realistic voice messages

Pros

  • Realistic responses
  • High-quality voice messages
  • Superior memory

Cons

  • No phone calls
  • No NSFW conversations

Cons

  • Strict NSFW filter

Image Quality

Question Mark Tooltip Icon

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

5.0

Character AI does not have an external image generator and does not support creating images within chats.

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

Pros


Cons

  • No AI image generator

Cons

  • No realistic-looking AI image generator

Privacy

Question Mark Tooltip Icon

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.

Privacy Score Summary

4.6 Average Score (50+ AI girlfriends tested) 5.0 Best Score 3.0 Worst Score

According to Character AI’s privacy policy, they do not monitor your chats. While they don’t offer billing discretion, it’s not needed since NSFW content is not allowed on their platform.

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

Pros

  • No chat monitoring

Cons


Cons

  • No billing discretion

Value for Money

Question Mark Tooltip Icon

Character AI allows you to send unlimited chat messages with their free plan, offering unbeatable value compared to other AI companion platforms. Their premium plan, costing $9.99 per month, provides early access to new features and priority during peak server times. On the flip side, Character AI is limited to just chatting and doesn’t offer any other features like in-chat image generation.

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

  • Unlimited chat messages with the free plan

  • Free plan has unlimited messages
