Measure how hard your text is to read using three complementary formulas: Flesch Reading Ease, Flesch-Kincaid Grade, and Gunning Fog. Paste any paragraph or marketing copy to get instant scores with color-coded difficulty bars. Sentences over 30 words are flagged for splitting. Passive-voice percentage and syllable breakdown round out the stats. All calculations run locally in your browser.
It computes Flesch Reading Ease (0–100, higher is easier), Flesch-Kincaid Grade Level (U.S. school grade), and Gunning Fog (years of education). All three run entirely in your browser with no server calls.
A score of 12 means a typical high-school senior is needed to read the text. For marketing and consumer-facing copy, aim for 7–9 grade level paired with a Flesch Reading Ease of 60 or above.
Any sentence containing 30 or more words appears in the flagged panel with its word count highlighted in red. These are the sentences most likely to fatigue a reader and prime candidates for splitting into two.
No. Syllable counting, sentence splitting, and all formula scoring run locally in your browser. Your text never leaves the page unless you explicitly configure the optional AI rewriting panel.
