Diary System — SkyrimNet Diary Feature

The Diary System allows the Player and NPCs to write personal diary entries with a manual generation, based on in-game events, emotional states, and memories.
Each entry is generated dynamically using LLM templating, rendered beautifully in the web UI, and can be read aloud using the NPC’s own voice via TTS. It is a large and deeply introspective summary of recents events, a way to peer into the character inner thoughts and a powerful aid for the LLM to better roleplay such character.

🧩 Core Components​

1. Prompt Generation​

The diary system builds a structured LLM prompt that includes:

  • The NPC’s name, background, and current emotional state
  • The most recent diary entry for narrative continuity
  • Recent memories (with timestamps and importance values)
  • Recent in-game events (using the event history template)
  • A detailed set of writing and style guidelines for authentic diary generation

2. Memory Integration​

Each diary entry is automatically:

  • Stored as a personal memory in SkyrimNet’s memory system
  • Tagged with emotional and importance metadata for recall weighting
  • Used by NPCs to influence dialogue, decisions, and emotional context in future interactions

This makes each diary entry not just writing — but a cognitive artifact the NPC can later remember and reference.

3. Web UI Presentation​

The diary entries are displayed in the Diary Viewer page:

  • Clean layout with entry metadata (location, date, emotion, importance)
  • Markdown-rendered text for immersive, journal-like presentation
  • Navigation between past entries (previous/next day)
  • Quick action buttons:
    • 🪄 Generate New Entry — create a new diary entry based on recent events
    • 🗣️ Voice — play the NPC’s TTS narration of the entry
    • ✏️ Edit — modify the entry manually
    • 🗑️ Delete — remove the entry

4. TTS Voice Narration​

Each diary entry can be read aloud using the NPC’s authentic voice:

  • Uses the currently chosen TTS with the NPC’s voice
  • Emotionally adaptive playback based on the diary’s tone (emotion field)
  • Markdown text is preprocessed before narration for smooth speech
  • Optionally cached for re-listening or continuous playback

This transforms the diary into a living, voiced memory system, where the player can hear the NPC’s inner thoughts in their own voice.
