How This Tool Works
100% Client-Side

Your data never leaves your device. All processing happens locally in your browser. No text is sent to any server, no data is stored, and no cookies track your usage.

Sentences are detected by matching text patterns ending in periods, exclamation points, or question marks. Paragraphs are identified by double newline characters.

  • Uses regex pattern matching for sentence boundaries
  • Calculates average and maximum sentence lengths in words
  • Handles edge cases like abbreviations and decimals
