16Core Character Mapper

16Core Character Mapper is a free tool that helps writers, screenwriters, and game designers build a memorable cast. Grounded in established psychological research, it's a secret weapon against bland characters that all feel the same.

Instantly compare your cast on the visual chart to see, at a glance, how their personalities will clash and connect—both with each other and the world you've built.

Key Features:

• Visually map character personalities across 16 core traits.
• Instantly compare multiple characters to spot clones and create dynamic contrasts.
• Organize your cast into groups (e.g., Main, Supporting, Background).
• Use the built-in questionnaire to help position your characters in the trait grid.
• Keep trait-specific notes and export them as .txt or .rtf for reference.
• Export the entire chart as a high-quality PNG for your story bible or notes.
• Switch between a clean light mode and a focused dark mode.
• Choose from nine languages to translate your trait grid and the questionnaire.

Works on Windows (10 or later), macOS (10.15+, Catalina or later) and all modern Linux distributions. The app is offered as donationware - it is completely free to use and donations are entirely optional. It is an ideal tool for anyone looking to move beyond flat character archetypes and build a memorable cast.
