Need to simplify AI-generated text? Make it sound naturally human.
Try our AI Humanizer →Five industry-standard readability formulas, calculated instantly in your browser.
Scores 0-100. Higher is easier. Used by the US military, government agencies, and publishers worldwide.
Maps text to a US school grade level. A score of 8.0 means an 8th grader can understand it.
Estimates years of education needed. Penalizes complex words (3+ syllables) heavily.
Uses character count instead of syllables. More reliable for shorter texts and technical writing.
Character-based formula used in the US Army. Fast and accurate for digital text.
Shows average sentence length, syllables per word, and percentage of complex words.
Practical tips to make your writing clearer and more accessible.
Break long sentences into two. Aim for 15-20 words per sentence on average.
Replace multi-syllable words with shorter alternatives: 'utilize' becomes 'use', 'demonstrate' becomes 'show'.
Cut unnecessary adverbs and qualifiers: 'very', 'really', 'actually', 'basically'.
Change 'The report was written by the team' to 'The team wrote the report'.
Guide readers with clear connectors: 'First', 'Next', 'However', 'As a result'.
Academic papers need different readability than blog posts. Match the grade level to your readers.
Flesch Reading Ease is a formula that scores text from 0 to 100 based on sentence length and syllable count. Scores above 60 are considered easy to read, while scores below 30 are very difficult. It was developed by Rudolf Flesch in 1948 and is one of the most widely used readability tests.
It depends on your audience. Blog posts and marketing copy should aim for 60-70 (8th-9th grade). Academic papers typically score 30-50. Legal and scientific texts often score below 30. The key is matching your readability to your readers' expectations.

We use a heuristic algorithm that handles common English patterns including silent e, -le endings, and -ed suffixes. It's accurate for most English text but may occasionally miscount unusual or borrowed words.
Both estimate grade level, but Gunning Fog penalizes complex words (3+ syllables) more heavily. Flesch-Kincaid tends to give lower grade estimates for the same text. Using both gives you a more complete picture.
The formulas were designed for English text. They rely on English syllable patterns and won't produce meaningful results for other languages. For non-English text, use language-specific readability tools.
