What is Readability Analyzer?
Readability Analyzer scores your writing with the Flesch Reading Ease scale and estimates its grade level, then shows you where to tighten it. It counts words, sentences, paragraphs, and reading time, and a skimmability preview flags dense paragraphs and bolds the key phrases it detects. Paste an article, email, or draft and watch the analysis update live. Everything runs in your browser, so your text is never uploaded.
How to use Readability Analyzer
Paste your text
Drop an article, email, or blog draft into 'Your text', or click Load example to try a sample. The analysis updates live as you edit.
Read the ease score
See your Flesch Reading Ease number and its band, from Very difficult to Very easy, on a color-coded scale. A caption translates the grade level into an approximate reader age.
Check the stats
Tiles show words, sentences, paragraphs, and estimated read time, plus average words per sentence and average syllables per word — the two levers that move the score most.
Scan the skimmability preview
Your text is redisplayed with detected key phrases in bold and any paragraph over four sentences flagged as Dense with a red marker, so you can spot walls of text at a glance.
Revise and re-check
Shorten flagged paragraphs and trim long sentences, then watch the score climb in real time. Keep editing until the readability lands where you want it.
