About This Tool

The Readability Checker calculates Flesch Reading Ease, Flesch-Kincaid Grade Level, and Gunning Fog Index for your text — showing you how hard or easy your content is to read. Lower grade levels generally improve engagement and comprehension for most audiences. Paste your content and get scores instantly. Free, no account, runs in browser.

How to Use

    Paste your article or page content into the input area.

  2. 2

    Readability scores (Flesch, Kincaid, Fog Index) are calculated and displayed.

  3. 3

    Use the feedback to simplify sentences or vocabulary where needed.
