Use to match tone to audience — academic submissions, business proposals, conference talks, or marketing emails. The target selector gives you an instant fit check.
Where lexical density measures information packing and readability measures grade level, formality measures *register* — a third independent axis.
Formality is a 0–100 score combining slang count, contraction count, first/second-person pronoun rate, passive voice frequency, formal markers ("furthermore", "consequently"), and average word length.
The target selector adjusts which range the score should fall into — academic (70–100), business (50–80), or casual (0–45).
Suggestions are generated when your text falls outside the target range, focusing on the most impactful adjustments.
It blends slang count, contractions, first/second-person pronouns, sentence length, passive voice, and Latin-root vocabulary into a single 0–100 score.
Academic ~70–100, business ~50–80, casual ~0–45. The target selector adjusts the suggestion thresholds.
