Differentiation starts with measurable text complexity - without sending student work to unnamed servers unnecessarily. Paste text into QuizFlex’s Reading Level Analyzer for Flesch-Kincaid grade level, Flesch Reading Ease, SMOG, ARI, Coleman-Liau, and context about what those numbers imply.

How to interpret results

Pair raw scores with your knowledge of learners - scores are guides, especially for poetry, multilingual writers, or highly technical jargon.

Recommended loop:

  1. Paste an informational paragraph you plan to assign.
  2. Confirm grade-band alignment (~±1 year is realistic tolerance).
  3. Revise overloaded sentences - the analyzer highlights why difficulty spikes.

Privacy-conscious design

The tool favors paste-in-browser workflows so quick checks stay nimble - great for PLC teams prepping leveled excerpts.
