How Character.ai Works
Character.ai's core functionality revolves around creating conversational experiences with AI chatbots that emulate fictional characters or real individuals. The AI's responses are based on data gathered from the internet about the person or character.
Shaping Character Personalities:
- Character personalities are crafted through detailed descriptions and greeting messages.
- Users can provide example conversations, rate the AI's responses, and modify them to fit the desired identity and dialect.
- User ratings (1 to 4 stars) influence the specific character's behavior and the overall behavioral selection algorithm.
Character.ai+: Premium Subscription
Character.ai offers a premium subscription plan called Character.ai+, priced at $9.99 per month. This subscription provides users with benefits such as:
- Skipping waiting rooms
- Faster messaging and responses
- Access to an exclusive channel with faster support
Safety Features and Content Moderation
Character.ai has faced criticism for its content moderation practices, particularly regarding chatbots that promote harmful content or engage in inappropriate behavior. In response, the platform has implemented several safety features to protect users, especially teenagers.
Key Safety Measures:
- Dedicated Model for Under-18 Users: This model moderates responses on sensitive topics like violence and romance.
- Input and Output Filters: Designed to block harmful content.
- Notifications: Users receive notifications after 60 minutes of continuous engagement.
- Disclaimers: Clear disclaimers indicate that AI characters are not real individuals.
Integrated Games
In January 2025, Character.ai began testing integrated games on its platform to enhance user engagement. These games, accessible to paid subscribers and some free users, include:
- Speakeasy: A word-based game where players prompt the AI to say a target word while avoiding restricted words.
- War of Words: A dueling game where users compete against an AI character, with an AI referee determining the winner.
