Why readability matters

Readability is one of the strongest predictors of whether people actually read — and understand — your content. Google, editors, and accessibility guidelines all reward writing that is clear and easy to follow. This Actor turns that abstract goal into hard numbers you can act on.

• Flesch Reading Ease (0–100): higher is easier. 60–70 is "standard" — comfortable for most adults.
• Flesch-Kincaid Grade: the US school grade level needed to understand the text (e.g. 8.0 = 8th grade).
• Reading time: estimated minutes at 200 words per minute.
• Difficulty label: Very Easy → Very Confusing, at a glance.

FAQ

Does it need an API key? No. Just provide URLs.

What language does it support? The formulas are tuned for English; other languages still return counts and reading time.

How is the main text extracted? Via trafilatura, with a <p>-tag fallback, so navigation and boilerplate are stripped out.
