Frequently Asked Questions

The formality score (0-100) measures how formal your writing is. It considers sentence length, contractions, passive voice, personal pronouns, formal vocabulary, and slang markers. Higher scores indicate more formal writing.
The dominant tone is classified based on keyword patterns: Professional (formal vocabulary, few contractions), Casual (contractions, slang), Academic (long sentences, passive voice, formal words), Friendly (personal pronouns, positive words), or Authoritative (imperative verbs, power words).
Audience fit suggests the best-suited audience for your text based on its formality and tone: Academic (research, papers), Business (professional communication), Casual (social media, blogs), or Technical (documentation, guides).
To increase formality: avoid contractions (use "cannot" instead of "can't"), use longer sentences, employ formal vocabulary (e.g., "furthermore", "consequently"), reduce first-person pronouns, and use passive voice where appropriate.
