Disclaimer: Readability scores are published formulas applied to estimated syllable counts. Passive voice, tone and style suggestions come from patterns and word lists, so they can be wrong in either direction.

Paste or type text and get counts, reading and speaking time, six readability formulas judged against the reader level you choose, a clarity checklist with the passages highlighted, keywords and key phrases (RAKE), and an extractive summary (TextRank). The Improve tab suggests fixes for long sentences, passive voice, jargon and filler that you accept or ignore one by one, and scores headlines from 0 to 100 with reasons. Transform tools cover find and replace with regex, duplicate and sort lines, extracting emails and dates, and a word-level comparison, and your drafts are saved with a version history. Everything runs in your browser and nothing is uploaded.
