Detail Mode Prompt
Learn how to choose a prompt template in Detail Mode and fill in the character settings (integrated info, custom instructions).
Detail Mode gives you more precise control over how the character responds. The order is to first pick a prompt template, then fill in the character settings accordingly.
Choosing a prompt template
system_prompt_id (the prompt template) becomes the base of the chat system prompt.
Since it determines the foundation—output format, description guidelines, writing style—choose one that fits your work's purpose.
| Template | When to use it |
|---|---|
| 1:1 Basic | General romance/narrative with one-on-one conversation with a single character |
| Simulation Basic | Simulation-style play that drives a world or situation |
| Creator Custom | When you want to write the entire set of instructions yourself |
Filling in the character settings
This is where you write detailed information about the character, such as role, appearance, personality, and speech style. Where it's saved depends on which template you chose.
- When you pick a template (1:1 or Simulation) → saved as
integrated_info(character settings and info) - When you pick Creator Custom → saved as
creator_custom_prompt
The two save methods are mutually exclusive. Depending on the template you choose, content is filled into only one of the two.
If you choose Creator Custom, you'll write the entire set of instructions from scratch without a prepared base. Because it offers high flexibility, you have to define even the output format and writing style yourself.
Character count and tokens
The limit varies by template type and the app language you're using. Only the Japanese (ja) environment gets higher limits; every other language environment (including English) shares the same limits.
| Category | All languages except ja | Japanese (ja) environment |
|---|---|---|
| Template (1:1 / Simulation) | 5,000 chars | 8,000 chars |
| Creator Custom | 7,000 chars | 10,000 chars |
You can use the {{char}} and {{user}} insert buttons in the input field.
Don't put length instructions (e.g., "always write at least 2,000 characters") in the prompt. Response length is managed by the chat mode, so putting length instructions in the prompt causes a conflict that can truncate replies or lower quality. A warning banner is also shown on the editing screen.
The character type governs the assembly
Even for the same character, the type determines which fields the AI prompt is assembled from.
- Default (
default) type → usesintegrated_infoorcreator_custom_prompt - Worldview-based (
worldview_based) type → uses the intro/worldview/secrets structure
Detail Mode handles the default type, and the character settings fields above become the source of the prompt. If you're curious about the worldview-based structure, see the Easy Mode Prompt document.
