Readability checker

Measures what your copy asks of a reader: the sentences that run past where they can follow, the passive voice, and the words borrowed from a brochure.

Why this is worth checking

Nobody reads a landing page the way its author reads it. The author knows what the sentence is trying to say, so a forty-word sentence with three clauses reads fine to them and stops everybody else. Grade level is a rough measure, but it catches the two things that actually lose people: sentences that never end, and words chosen to sound expert rather than to be understood.

What it looks at

  • Sentence length, longest ones first
  • The reading grade of the whole piece
  • Words longer than the job needs
  • Jargon the reader may not share

Counts sentence length and syllables. It cannot tell you whether what you wrote is true or useful, and those matter more.
