Improve Readability with Text Analytics
Writing clearly is essential whether you are publishing blog articles, writing technical documentation, crafting student essays, or preparing business proposals. The Text Analyzer evaluates your writing structure in real time, calculating standard readability formulas, vocabulary diversity, and sentence metrics to ensure your message is clear and accessible.
Understanding Readability Scores
The tool uses two of the most widely adopted literacy benchmarks in education and publishing:
- Flesch Reading Ease: Scores your text on a 100-point scale based on average sentence length and average syllables per word. Higher scores indicate material that is easier to read, while lower scores denote complex, academic, or technical prose.
- Flesch-Kincaid Grade Level: Translates reading difficulty into the corresponding United States school grade level (e.g. a score of 8.0 indicates that an average 8th grader can easily comprehend the text). Most general web content aims for an 7th to 8th grade reading level.

Tips to Improve Your Readability
- Break up long sentences: If a sentence exceeds 25 words, consider dividing it into two concise thoughts.
- Choose simple alternatives: Replace multi-syllable jargon with everyday equivalents (e.g. use "help" instead of "facilitate", "use" instead of "utilize").
- Increase vocabulary diversity: Check your Type-Token Ratio (TTR). A low diversity score signals repetitive vocabulary.
- Eliminate passive voice: Write in active voice to make sentences more direct and punchy.
