FAQ

What does this readability tool measure?
It computes Flesch Reading Ease (0–100, higher is easier) and Flesch-Kincaid Grade Level (U.S. school grade). Both use word, sentence, and syllable counts with standard formulas.
Does this tool send my text to a server?
No. All analysis runs locally in your browser. Your text is never sent to a server or stored.
Why might my score differ from other tools?
Syllable counting is approximated with heuristics; different tools use different algorithms. Results are consistent within this tool but may vary across tools.
What Flesch score should I aim for?
For general audiences, aim for 60–70 (8th–9th grade). For technical docs, 50–60 is common. Very high scores (80+) indicate very simple text.
