Use the adverb detector when editing fiction, marketing copy, or any writing where pace and vividness matter. Hemingway-style guidance targets adverb rates under 4%; tight ad copy often goes below 2%.
Adverb detection is a stylistic metric, like passive voice — it surfaces patterns rather than scoring difficulty. Use alongside the Filler-Word Detector for a fuller weak-prose audit.
The detector flags every -ly word in the text, excluding a stoplist of -ly words that aren't adverbs (family, lovely, jelly, etc.).
Adverb rate is the percentage of words that are adverbs. Hemingway-style writing keeps the rate below 4%; tight ad copy often stays under 2%.
Strict mode adds a check that the word has an adjective stem — fewer false positives but may miss neologisms.
Stephen King's rule: "The road to hell is paved with adverbs." They're a sign you chose a weak verb that needed propping up. "Ran quickly" → "sprinted".
Family, lovely, jelly, etc. — these are excluded from the count. Enable strict mode for tighter detection at the risk of missing neologisms.
Under 4% for tight prose. Under 2% for ad copy. Some genres (literary fiction) tolerate higher rates by design.
输入
"She quickly opened the door and softly whispered her name."
输出
2 adverbs in 9 words (22% adverb rate) — heavy.
"Quickly" and "softly" both weaken stronger verb choices. "She flung the door open and whispered her name" reads tighter and more vivid.
