Readability Analyzer
Flesch-Kincaid, Gunning Fog, and SMOG scores computed on the extracted article content, not raw HTML, plus a plain-English reading level.
The article text is extracted with the same algorithm Firefox Reader View uses, so scores reflect the actual content, not navigation or footer boilerplate.
