What Data·yze Readability Analyzer is
Data·yze Readability Analyzer estimates how readable a passage may be for a chosen audience. It reports measures including Flesch-Kincaid Reading Ease, Gunning Fog Index, Kincaid Grade Level, SMOG, Dale–Chall, and Fry Reading Graph. A paragraph view provides statistics and shows how readability changes across a document. Users can enter text or upload a file, then save or download their input. The page also lists sentence analysis and clarity recommendations, and links to a difficult and extraneous word finder, passive voice detector, and spell checker. A separate Website Readability Analyzer evaluates an individual webpage and average readability across a site; its crawler is limited to 1,000 pages per user per day. Data·yze says analyzed passages are not collected or stored, though passage length is retained for performance analysis. Writing-tool uploads are cached and automatically expunged within seven days, possibly sooner. The app is free and ad-supported. Data·yze cautions that readability metrics are heuristic estimates, not measures of writing quality, and that the analyzer works best with plain text.
