Character.AI is a new product powered by our own deep learning models, including large language models, built and trained from the ground up with conversation in mind. We think there will be magic in creating and improving all parts of an end-to-end product solution.

Here is a detailed look at the technology behind Character.AI:

  • Large language models (LLMs) are a type of deep learning model that are trained on massive datasets of text. This allows them to learn the statistical relationships between words and phrases, which in turn allows them to generate text that is both coherent and meaningful. Character.AI uses LLMs to power its conversation engine, which allows users to have natural and engaging conversations with their characters.
  • Conversation memory is another key technology behind Character.AI. This feature allows the AI to remember previous conversations, which helps it to keep track of the context and flow of the conversation. This makes it possible for Character.AI to have more meaningful and nuanced conversations, as it can refer back to previous conversations and build on them.
  • Personality is another important aspect of Character.AI. Each character has its own unique personality, which is reflected in the way it talks and behaves. This personality is created by a combination of factors, including the character’s backstory, its goals, and its values. Character.AI uses this personality to generate text that is consistent with the character’s persona.
  • User feedback is also an important part of the Character.AI experience. After each conversation, users are asked to rate the character’s performance. This feedback is used to improve the character’s conversation skills and personality.

Overall, Character.AI is a powerful tool that can be used to create engaging and meaningful conversations with AI characters. The technology behind Character.AI is constantly evolving, and we are always working to improve the product. We believe that Character.AI has the potential to revolutionize the way we interact with AI, and we are excited to see what the future holds for this technology.

In addition to the above technologies, Character.AI also uses a number of other features to improve the user experience, such as:

  • Text-to-speech allows users to hear their characters speak.
  • Voice commands allow users to control their characters with their voice.
  • Customization allows users to customize their characters’ appearance, personality, and skills.
  • Community allows users to share their characters with others and collaborate on projects.


Character.AI is still under development, but it has already become a popular tool for creators and users alike. With its powerful technology and innovative features, Character.AI is poised to become a major player in the AI conversation space.
