How to customize an AI character on Charms
By the Charms team
A character feels yours when its appearance, personality and way of speaking fit the same idea. Customization in Charms starts with the character you create. You can also guide an existing character through conversation, but asking it to change its tone does not edit its creator’s published identity.

Before choosing a look, decide what you want the conversation to feel like. A patient creative partner, an enthusiastic explorer and a dry-witted storyteller need different directions. Write one sentence about who your character is and why someone would enjoy talking to them. This becomes a reference when later choices start pulling in different directions.
Your next three steps
1. Define
Choose one clear character idea.
2. Refine
Describe behavior you can recognize.
3. Test
Try a private conversation.
Give the appearance and personality the same direction
Use the creation options to shape a recognizable look, then describe behavior that fits the identity. An avatar introduces a character; it does not explain how they listen, disagree or respond to uncertainty. Instead of only “curious and helpful”, try “asks one question before offering advice, notices small details and admits when unsure”. Soul is Charms’ name for the character’s personality configuration.
A description you can adapt
This is an original writing example, not a character already listed in Charms. Use it as a starting point and replace the details with your own.
Identity
An unhurried restorer of old radios who is interested in the stories behind everyday objects.
Behavior
Asks what I have tried before suggesting a next step. Explains one idea at a time and admits uncertainty.
Try it
I found an old radio in a fictional attic. What would you ask me before deciding what to do with it?
Test a change with a real conversation
Keep your character private while you experiment. Ask about something familiar, introduce a disagreement and suggest a fictional scene. Look for a recognizable point of view across all three. If the replies feel too formal, describe the language you want rather than adding another adjective. Change one thing and try again; generated replies will vary, so one answer is not a complete test.
Know what a chat request changes
You can ask a character to answer more briefly, explain a thought or continue a scene in your language. Those directions belong to the conversation; they do not give you ownership of someone else’s character. Likewise, describing a speaking style means how text is expressed, not uploading or assigning an audio voice. Sending a voice note is a separate chat feature.
Keep identity, memory and visibility separate
Personality describes who the character is. Memory helps carry useful context from your conversations forward. If a character misses a detail about your shared story, clarify that detail instead of rewriting its identity. When your own character feels ready, review what will appear publicly before publishing. Keep personal information out of the public description and check current credit requirements in the app.
