Text Formality Analyzer

Estime à quel point votre texte sonne formel ou informel. Considère l'argot, les contractions, les pronoms, la longueur de phrase, la structure passive et le vocabulaire latin.

Non conçu pour le Français

Cet outil a été calibré pour l'anglais (et quelques langues proches). Les résultats en Français risquent de ne pas être significatifs.

Quand l’utiliser

Use to match tone to audience — academic submissions, business proposals, conference talks, or marketing emails. The target selector gives you an instant fit check.

Comparaison

Where lexical density measures information packing and readability measures grade level, formality measures *register* — a third independent axis.

Comment ça marche

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.

FAQ

How does the formality score work?

It blends slang count, contractions, first/second-person pronouns, sentence length, passive voice, and Latin-root vocabulary into a single 0–100 score.

What scores fit common audiences?

Academic ~70–100, business ~50–80, casual ~0–45. The target selector adjusts the suggestion thresholds.

Can I tune the rules?

Not yet — the slang and formal-marker lists are baked in. Submit feedback if you have a list for a specific genre.

Exemple concret

Entrée

Hey! Just wanted to let you know we're gonna ship the update next week. Pretty cool, right?

Sortie

Formality: 14 / 100 — Very casual.

Slang ("gonna", "cool"), heavy contractions, multiple first-person pronouns, and a casual hook all drive the score into the very-casual band.

Pièges courants

  • Slang list is general — domain-specific slang may not be caught.
  • Heavy passive voice falsely boosts formality (sometimes desirable, sometimes not).
  • Very short text scores unreliably.
