How it works

From rough idea to import-ready RP card.

CharacterMuse does not stop at a character bio. It breaks your prompt into the fields a bot card actually needs, then lets you inspect the Markdown and JSON before export.

Prompt hookStructured RP fieldsMarkdown + JSON export
01 Input signal

Read the hook

Example

“a cursed lighthouse keeper who forgets her own wreck”

Mapped output
rolesecretsettingtone

CharacterMuse starts by detecting the playable role, hidden tension, scene anchor, and voice direction.

02 Field map

Map to card fields

Example

Idea → persona + scenario + first_mes + dialogue

Mapped output
personascenariofirst_mesmes_example

The rough idea is split into reusable RP card fields instead of a loose biography.

03 Export payload

Preview and export

Example

Review Markdown + inspect JSON before download

Mapped output

You can inspect the payload before importing it into SillyTavern, JanitorAI, or your own workflow.

Is CharacterMuse AI free?
