How the calculations work
- Words contain letters or numbers; internal apostrophes and hyphens stay within a word. Standalone punctuation is excluded. Hindi and other spaced scripts are supported; languages without spaces may need specialist segmentation.
- Characters count Unicode code points, including spaces and line breaks. A combined emoji or accented character may contain several code points. “No space” excludes all whitespace.
- Sentences use browser language segmentation when available, with a punctuation-based fallback. Paragraphs are separated by blank lines; a single line break stays within a paragraph.
- Reading time assumes 200 words/minute and speaking time 130 words/minute, rounded up to whole seconds.
- Reading level is an approximate English Flesch Reading Ease band: Easy (70+), Medium (50–69), or Difficult (below 50). Syllables are estimated; fewer than 30 words is “Too short”, and text with non-Latin letters is “N/A”. Language is not automatically detected: use this estimate only for English. This is not a validated grade-level assessment.
- Keyword density is each word’s frequency divided by all words, ignoring case. Common words are included. Equal frequencies keep first-appearance order. This is a frequency measure, not an SEO score.
- Average word length counts letters and numbers, excluding apostrophes and hyphens. Format Spaces preserves paragraph breaks. Only your theme preference is saved; text is lost on refresh or closing the tab.
