How to Create an AI Character Card

What an AI character card is

An AI character card is a structured profile for roleplay tools. It usually contains the character's identity, personality, scenario, first message, example dialogue, and sometimes embedded PNG metadata for card-aware tools.

The goal is not to write a long biography. The goal is to give the AI enough stable context to act like the character without contradicting the setting.

Core parts of a useful card

• Character purpose: explain what kind of roleplay or interaction this card supports.
• Personality: describe stable behavior, values, habits, fears, and boundaries.
• Scenario: set the starting situation, location, relationship, and current tension.
• First message: begin with a scene that immediately shows tone, action, and character voice.
• Example dialogue: show how the character speaks instead of only explaining it.
• Speaking style: keep narration, dialogue, honorifics, and emotional pacing consistent.

PNG metadata and Chara Card V2

Some roleplay tools can read character data embedded inside a PNG image. Chara Card V2 is a common structure for storing character fields in a more portable way. If metadata is lost during image editing, compression, or re-saving, the card may look like an image but import without usable data.

Submission-ready checklist

• The character's purpose is clear.
• Personality and behavior do not contradict each other.
• The first message fits the world and gives the user something to respond to.
• Description and dialogue are not mixed in a confusing way.
• The card is not only a long explanation with no playable scene.
• PNG metadata has been checked before posting or sharing.
