Character Builder

The Character Builder lets you create a character database (called a "Character Cast") that the AI uses during Step 2 (Vision Analysis) to accurately identify and name characters in your webtoon panels.

Why Use Character Builder?

Without a Character Cast, the AI in Step 2 can only describe characters generically ("a girl with blue hair", "the tall man"). With a Character Cast, the AI can identify characters by name, apply their voice settings, and maintain consistency throughout the narration.

How to Use

Building a New Cast

1. Open the Character Builder in WTN Suite
2. Load sample images that contain your characters (a few panels with clear character appearances work best)
3. The AI automatically detects faces in the images using character detection
4. For each detected face, assign a Character Name/ID
5. Optionally add voice settings and appearance notes
6. Save the cast as a .cst file

Using a Cast in the Pipeline

1. Before running Step 2 (Vision Analysis), load your .cst file
2. The AI will use the character embeddings to identify characters by name
3. Character names carry through to Step 3 (Narrative) and audio generation

Features

• Automatic face detection — AI detects character faces in your sample images
• Manual ID assignment — you decide who each detected face is
• Cast export — save character data as .cst files (all plans)
• Cast import — load previously saved casts (Pro plan only)
• Character profiles — store appearance attributes and voice preferences per character
• Embedding database — the system stores visual embeddings for more reliable recognition

Tips

• Use 3-5 clear panels per character for best recognition accuracy
• Include images showing characters from different angles and expressions
• Update your cast if new characters appear in later chapters
• Naming characters consistently (e.g., always "Mia" not sometimes "Mia" and sometimes "Main Character") produces better narratives
• On Pro plan, you can import casts across projects — build once, reuse everywhere
