How This Tool Improves Your Writing

Our readability checker uses proven linguistic analysis to help you write clearer, more engaging content.

Sentence Length Analysis

Long sentences are harder to follow. We highlight sentences over 14 words (hard) and 25 words (very hard) so you can break them up.

Passive Voice Detection

Passive voice weakens your writing. We identify passive constructions so you can rewrite them in active voice.

Adverb Highlighting

Adverbs often weaken verbs. We flag them so you can choose stronger verbs instead of relying on modifiers.

Complex Phrase Simplification

Phrases like "in order to" can be simplified to "to". We identify wordy phrases that can be made more concise.
