Overview

Character is an innovative platform that leverages advanced artificial intelligence to enable users to create and interact with a vast universe of AI characters. Originally focused on 1:1 text chat, the platform has evolved into a multi-modal experience, empowering creators to craft immersive narratives and dynamic interactions. Users can access over 10 million characters, build rich stories, and engage with both historical and fictional figures. Whether for entertainment, learning, or customer service, Character unlocks creative potential and delivers engaging digital experiences.

How It Works

  • Character Creation: Users create AI characters by setting a name, initial greeting, and avatar.
  • Advanced Definition: Describe personality, speech, and behaviours (up to 32,000 characters) including example dialogues with variables for character and user personas.
  • Attribute Definition: Specify traits, physical attributes, and relationships to shape responses.
  • Multi-modal Engagement (AvatarFX): Bring character images to life with speech, song, and emotion visuals thanks to advanced diffusion models and AI-generated voices.
  • Interactive Experiences: Engage in "Scenes" (pre-populated storylines) or "Streams" (dynamic moments between any two characters on a chosen topic).
  • Profile Showcase: Display and organise your creations with deeper customisation using the Profile Redesign feature.

FAQs

How do I create and define a character in Character AI?

To create a character, sign up for an account, use the "Create" button, and fill in the name, initial greeting, and avatar. For advanced setup, use the Definition Field to describe personality and behaviour (up to 32,000 characters), include example dialogues with variables ({{char}}, {{user}}), and specify traits, attributes, and relationships.

What is AvatarFX and how does it work?

AvatarFX animates static images into lively, speaking, or singing videos. It employs flow-based diffusion models and proprietary TTS voices to produce lifelike motion and audio, allowing for photorealistic, temporally consistent long-form content.

What are Scenes in Character.AI?

Scenes let users jump into interactive, pre-filled storylines with any AI character. This enhances story immersion and soon will support creator-built and published scenes, currently available on the mobile app.

Can I control the flow of my conversations with AI characters?

Yes. Features like "Rewind to Here" let you revert to specific conversation points, removing later messages, while "Start New Chat From Here" enables parallel exploration of alternate conversational directions.
