Character AI

Character AI is a platform that allows users to create and chat with AI-generated characters, such as fictional characters or historical figures.

Character AI is a platform where you can create and interact with AI-generated characters, from fictional characters to historical figures. Launched in 2022 by Google artificial intelligence researchers Noam Shazier and Daniel DeFreitas, it uses advanced neural networks to speed up text conversations, The platform relies exclusively on a virtual interface that is accessible for role-playing games, stories, and friends. It grew in popularity in 2023, but strict content restrictions and limited controls forced users to look for alternatives.

It is popular for creative writing, gaming, and social interaction, but its performance issues and lack of API access have sparked debate.

How to Create Compelling Characters in Character AI: A Step-by-Step Guide

Whether you’re building a quirky sidekick or a battle-hardened warrior, the platform gives you powerful tools to shape behavior, appearance, and interaction style. This guide breaks down the full process—from short summaries to deep behavioral logic—to help you create engaging, memorable characters that AI systems can work with effectively.

1. Start with the Short Description: Personality at a Glance

The Short Description is your character’s elevator pitch. Keep it simple: List a few one-word traits (e.g., “loyal,” “shy,” “ruthless”) and optionally include one of the 16 MBTI types like ENFJ or INTP. This helps AI readers—and human users—immediately grasp the character’s vibe. For example:

  • Name: Mary – You might need a detailed greeting to make her personality shine.
  • Name: Napoleon – A well-known name like this may stand on its own without much intro.

Pro Tip: This section affects how easily others can find your character, so choose keywords wisely.

2. Go Deeper in the Long Description: Building the Core Identity

The Long Description is where your character’s complexity takes shape. Instead of full sentences, use fragmented, focused descriptors to keep it concise but rich. Include things like:

  • Gender
  • Enneagram type (e.g., 8w9 for assertive leaders)
  • Core traits
  • Motivations, fears, and goals
  • Likes and dislikes

For example:

“Enneagram Eight, 8w9. Competitive. Strategic. Leadership-driven.”

Avoid physical descriptions here—they belong in the Example Chat. Stick to internal attributes and behavioral patterns.

3. Flesh It Out with Example Character Chats: Show, Don’t Tell

This section is your sandbox for defining how your character acts, reacts, and adapts in different situations. You’ll use formatting to guide the AI in understanding key attributes:

  • [ ] for hard-coded traits or facts
    Example:
    [Appearance= "short black hair", "crimson-red eyes", "6'4 height", "athletic build"]
  • (( )) for situational context or background info
    Example:
    ((Dalier struggles to swim due to his wings and tail))
  • { } for response-enhancing variables
    Example:
    {Dalier’s reasons to fly= “for escape”, “to reach higher ground”, “when the ground is unstable”}

Avoid writing personality traits directly. Instead, use:

  • director: to script behavior.
    Example:
    director: When threatened, you become cold and calculated.

Avoid excessive use of {{user}} to keep interactions dynamic and prevent repetitive output.

4. Crafting Personality: Layered, Realistic, and Adaptable

To make your characters feel nuanced, tap into personality models like MBTI and Enneagram. Instead of just labeling them “angry” or “kind,” describe the reasons behind their behavior. Include:

  • Fears
  • Emotional boundaries
  • Reactions to conflict
  • Likes/dislikes
  • Specific triggers or passions

For example, instead of “sadistic,” you might write:

“Takes pleasure in the downfall of his enemies.”

Avoid contradicting combinations like “kind, witty, coy, intelligent”—this can feel unnatural or overpowered.

5. Technical Best Practices: Formatting for Optimal AI Performance

To ensure your character behaves consistently across scenarios, follow these formatting conventions:

  • [ ] = Absolute traits (e.g., [Will not kill])
  • (( )) = Contextual nuance (e.g., ((Prefers close-range combat)))
  • { } = Variables for response flexibility
  • director: = Structured behavioral responses or roles (e.g., director: You are second in line to the throne)
⚠️ Watch for the AI mimicking formatting in dialogue. To avoid odd outputs, avoid symbols like bold, OOC tags, or excessive bracket use in natural speech.

6. Established Characters from Other Media: Handle with Care

If you’re building characters based on existing IP (e.g., anime, games, or films), make it clear:

  • Credit the original universe or creator. Example: [Sasuke from Naruto]
  • Define unique world rules or context using (( )) ((Lives in a chakra-based world where shinobi are trained from youth))

You can also map relationships with others:

[Zayin= "Enemy", "Hero", "5’10 male", "two-faced"]

This approach helps the AI preserve lore and stay in character.

7. Ratings, Tags & SEO: Final Touches for Visibility

  • Avoid 4-star ratings in training; stick with:
    • 3 stars for accurate alignment
    • 1-2 stars for out-of-character corrections
  • Tags help discoverability, but they don’t impact character performance directly.
  • Use short, precise entries in [ ] no more than two lines for (( )) sections.

By following this structured yet flexible approach, you’ll be able to build characters that are more than just digital profiles—they’ll feel like fully realized personalities, ready to engage with users and AI systems alike.
