AI character personality: traits, templates and examples
By the Charms team
A character personality works best when it describes observable behavior. A long list of adjectives often gives an AI little guidance about what to say next. Start with a clear identity, a few consistent habits and a recognizable way of speaking.

Separate identity, personality and speaking styleReplace vague traits with concrete behaviorUse a short description draft before the creation flowWhat traits, values and quirks add to a personalityTest ordinary questions and unexpected turnsSeparate identity, personality and speaking style
Identity tells us who the character is: its role, interests and background. Personality describes how it approaches a conversation. Speaking style describes the words, rhythm and level of detail it uses. Keep these aligned. A patient creative partner can be curious without sounding like a formal instructor in every reply.
Your next three steps
1. Identity
Choose a role and two interests.
2. Behavior
Describe what each trait looks like.
3. Test
Check the speaking style in different questions.
Replace vague traits with concrete behavior
Instead of only writing friendly, describe what friendliness looks like: the character welcomes questions, asks one follow-up at a time and avoids talking down to people. Give each trait a small behavior you can observe in a test chat. Two or three coherent habits usually provide a clearer starting point than ten competing adjectives.
Use a short description draft before the creation flow
Draft the character’s role, two interests, a conversational habit and a boundary. For example, an original photography enthusiast notices everyday details, asks what you want to capture and avoids pretending to have visited places it has not been told about. This is a writing exercise, not a listed Charms character or a special prompt syntax.
A reusable personality checklist
Template: [name] is a [role] interested in [two interests]. They value [value], show [trait] by [observable behavior] and have a habit of [quirk]. They speak in [style] and avoid [boundary]. Example: an original photography enthusiast values curiosity, notices small details, asks one question at a time and uses short, warm sentences. They avoid deciding the other person’s actions. Adapt this writing draft to the creation options in Charms; it is not a list of required app fields or an audio-voice setting.
What traits, values and quirks add to a personality
Traits describe tendencies: curious, patient or cautious. Values explain choices: honesty might lead a character to admit uncertainty. Interests and hobbies give it topics to explore. A habit or quirk adds a small recurring behavior, such as noticing colors, without repeating a catchphrase every turn. A fear can create fictional tension, but should not dominate every conversation. Use only details that change how the character responds; these are writing ingredients, not required Charms settings.
Test ordinary questions and unexpected turns
In Charms, try your character with a greeting, a practical question and a change of subject. Look for a consistent speaking style rather than the same repeated sentence. Revise one trait at a time so you can tell what improved the response. Keep your draft private while refining it, then review the public profile before publishing.
Explore CODY’s public profile for an example of a warm, curious identity. Notice what gives the personality direction, then write your own original character.
