Readability Analyzer

Standard readability formulas like Flesch-Kincaid, Gunning Fog, and SMOG measure text complexity based on sentence length and syllable count. They are a useful start, but they can't tell you whether a text fits your students, which words will trip them up, or how to fix it.

This tool goes beyond grade-level scores and reads the text the way a reading specialist would: it finds vocabulary to pre-teach, flags sentences that are hard to follow, and suggests rewrites and supports suited to your students' grade and reading level.

Research in cognitive load theory shows that needlessly complex language makes students spend effort decoding words instead of learning the content. Matching the text to your students leaves more of that effort for learning.
