💡 About This Tool

Whether you’re writing for a global audience, a classroom, or a professional journal, matching your text to the right grade level is key.

This tool calculates your Flesch-Kincaid Grade Level, Flesch Reading Ease, and Gunning Fog Index. It highlights long sentences and complex vocabulary in real-time, pinpointing exactly where your writing might lose a reader’s attention.

📘 Pro Tips for Better Writing

  • Hit the "Sweet Spot": Target a Flesch Reading Ease score of 60-70 for general web content. This ensures your text remains accessible to the widest possible audience.
  • Swap Complex Words: Review words underlined in red (3+ syllables). Replacing "utilize" with "use" or "initiate" with "start" often makes your writing more punchy.
  • Shorten Long Sentences: Review sections highlighted in yellow (20+ words). Splitting these into two separate thoughts significantly boosts comprehension.
  • Match Your Audience: Use the Grade Level indicator to verify that your academic paper hits the "College" mark or your blog post stays around "8th Grade."
