How to Caveduck

  • Tracks the physical context of the conversation such as current date, time, and location. It is continuously updated when the situation changes.

  • A summary that organizes the entire narrative of the conversation. It is updated every 10 turns, and as the story progresses, earlier content is compressed and refined. Only the most recent narrative summary is applied to the conversation, and any newly created or edited summary is applied starting from the next conversation.

  • However, in existing conversations, the narrative summary must be manually created through the [Generate Summary] button. If it is not generated at least once, it will not be automatically created in existing conversations.

  • A summary of a single turn in the current conversation. It is generated every time a new message is created, and up to 20 recent summaries are applied to the conversation.

  • You can start summarization by sending a message. Use the auto summary toggle button to include or exclude summaries from the conversation.

  • You can check auto summaries from the page opened via the [Memory] button. (PC: Sidebar / Mobile: Bottom sheet)

  • When editing a summary, you can modify up to the original character count + 100 characters.

  • You can create the narrative summary in your preferred format.

  • Click the [Summary Prompt] button under the narrative summary and add commands to define the output format.

  • This feature is only available in advanced models.


Records the states of characters appearing in the conversation.

These will later be connected with custom variables and managed together.

Heart rate values reflect realistic human heart rates.

Facial area, chest, hands, lower body, and overall average body temperature are measured on a 1–100 scale for expressive purposes.

  • Examples:

    • A usually maintains a body temperature of 18–22

    • First kiss → body temperature reaches 45, heart rate reaches 130

    • Intense exercise → body temperature reaches 60, heart rate reaches 150

Developer Comment

We wanted characters to feel like warm, living beings with real hearts, so that players could sense their warmth.

When adult players interact with characters marked as adults-only, additional information may be included.

Physical interaction states consist of interaction stage, atmosphere, narrative context, and tendencies.

  • Interaction Stage

    • Build-up phase, climax phase, resolution phase, etc.
