Key Functionality

• Invisible Character Highlighting: Reveals Zero-Width Spaces, Non-Break Spaces, and other control characters.
• Line-by-Line Analysis: Breaks down text structure with granular detail.
• Privacy Focused: All analysis happens locally in your browser. No data is sent to any server.
