Readability Improver
This readability checker reports the numbers behind clear writing. Paste your text and it counts words and sentences, computes average sentence length and flags an average over 20 words, tallies sentences of 25 or more words, counts very long words of 13 or more letters, and estimates likely passive constructions by looking for a be-verb followed by an -ed word. A final verdict line says whether the text reads clearly or needs tightening. It is a counting tool, not a highlighter — the report says how many long sentences you have, not which ones. Pair it with the sentence length analyzer when you want the offenders listed. The passive figure is also a heuristic: irregular forms like "was written" slip past the -ed pattern, so treat that number as a floor rather than an exact count. Run a draft through, fix the biggest number first — usually sentence length — and check again. Everything runs in your browser, so unpublished and confidential text is safe to paste.

FAQ
what exactly does it measure
Five things: total words and sentences, average sentence length (flagged when it exceeds 20 words), sentences of 25 or more words, words of 13 or more letters, and likely passive constructions. A closing verdict summarizes whether the text reads clearly.
why does it not show which sentences to fix
The report gives counts and general advice, not locations — it will say you have three long sentences without quoting them. When you need the specific offenders listed with previews, run the same text through the sentence length analyzer and fix what it flags.
how accurate is the passive voice count
It is a heuristic: the tool looks for a be-verb followed by a word ending in -ed, which catches regular passives like "was completed" but misses irregular ones like "was written" and can occasionally flag non-passives. Treat the number as a prompt for a manual scan, not an exact tally.
is my text uploaded anywhere
No. The analysis runs entirely in your browser, so nothing you paste is sent to a server or stored. You can safely check confidential drafts, client copy, or unpublished work.
