How It Works

Once the editor loads, type or paste your text and select Check. The analysis highlights elements that might need attention:

  • Red Highlights: These indicate complex sentences that might be difficult to understand. Consider breaking them into shorter, clearer statements.
  • Yellow Highlights: These show sentences that are somewhat hard to read. Try simplifying them for better clarity.
  • Blue Highlights: These mark adverbs, passive voice, and qualifiers that might weaken your writing.

What Your Readability Level Means

The checker gives you a reading grade, the U.S. school grade a reader needs to follow your text comfortably, and a readability level that puts it in plain words. Lower grades are easier to read. Use the level that fits your audience as your target.

Very Easy / EasyMost readers can follow it at a glance.Social posts, consumer emails, help articles

What the Highlights Mean

  • Red: very hard-to-read sentences. Usually long, with several clauses. Break them up with the free Sentence Splitter.
  • Yellow: hard-to-read sentences. Shorten them or swap complex words for simpler ones with the Text Simplifier.
  • Blue: adverbs, passive voice, and qualifiers. Words that can weaken a sentence. Rewrite passive sentences with the passive to active voice converter and trim extra words with the Filler Words Remover.

How to Improve Your Readability Score

  1. Keep one idea per sentence. Long, multi-clause sentences raise the grade fastest.
  2. Prefer common words. "Use" instead of "utilize," "help" instead of "facilitate."
  3. Write in active voice. Put the person or thing doing the action first.
  4. Cut adverbs and qualifiers such as "very," "really," and "quite" when they add nothing.
  5. Break up the page. Short paragraphs, headings, and lists help readers scan; see how people scan web pages in an F-pattern.

Frequently Asked Questions

Is this readability checker free?

Yes. You can run 10 readability checks per day without signing up. Paste or type your text in the editor and press Check to see your reading grade, readability level, and highlights.

What is a good readability score?

It depends on your readers. For most web content, aim for a level of Good or Easy, which many style guides put at around an eighth-grade reading level. Technical or academic writing can sit higher when the audience expects it.

What does the reading grade mean?

The reading grade estimates the U.S. school grade a reader needs to follow your text comfortably. A lower grade means the text is easier to read. It is based on things like sentence length and word complexity, not on whether your ideas are correct.

How do I lower my reading grade?

Split long sentences, replace complex words with common ones, use active voice, and cut adverbs and qualifiers that don't add meaning. Start with the sentences highlighted in red, then the ones in yellow.

Does readability affect SEO?

Google has said it does not use readability scores as a ranking signal. But clear writing helps visitors understand your page, stay longer, and act on it, which is what search engines aim to reward. Treat the score as a guide for readers, not a ranking target.

Can I check readability without leaving my browser?

Yes. The free Orwellix Readability Chrome extension checks pasted text of up to 5,000 characters for reading grade, hard-to-read sentences, adverbs, qualifiers, and passive voice.
