Why focus on "-ly" adverbs?

Adverbs ending in "-ly" are the most frequent and overused type in English writing. Authors like Stephen King famously advise cutting them because they often signal a weak verb choice. For example, "she ran quickly" can be rewritten as "she sprinted" for greater impact.

Does this catch all adverbs?

This tool detects adverbs ending in "-ly", which covers the vast majority of adverbs in English prose. It does not detect non-ly adverbs such as "very", "just", "soon", "often", "here", or "there" — those require dictionary-based part-of-speech tagging.

What is a good adverb density?

There is no universal rule, but many style guides suggest keeping adverb density below 2–3 per 100 words for fiction. Non-fiction and technical writing can be slightly higher. The goal is intentionality — every adverb should earn its place.

Is my text sent to a server?

No. All analysis runs entirely in your browser using JavaScript. Your text is never transmitted anywhere.

Are words like "family", "apply", or "fly" flagged?

No. The tool matches only words that end in "-ly" preceded by at least two letters, and it excludes a built-in list of common non-adverb "-ly" words such as "family", "reply", "supply", "early", "only", "likely", "friendly", and others.
