Lexicon-based Reading Difficulty Prediction

This page is a demonstration of a text classification approach to estimating the reading difficulty of text.

Accuracy generally improves with text length. The software will provide estimates for texts of any length, but a minimum length of 30 words is recommended.

Type or paste your text into the box below and press "Submit" to obtain an estimate of the difficulty of your text.
