What is Text Readability?

A quick introduction

Readability is the ease with which a reader can understand a written text.

A higher readability makes reading much easier and faster for any reader, but it is especially important for those who do not have high reading comprehension. In average-readers, raising the readability level of a text from mediocre to good can make the difference between success and failure of its communication goals.

Thanks to this endpoint, you will easily monitor the readability of your texts before publishing them, to make sure they work as intended for its target public.

Our API uses the Flesch formulas, the most popular reading-ease formulas. In this formulas, higher scores mean that the text is easier to read.
