Data·yze Readability Analyzer
Data·yze Readability Analyzer estimates how readable text may be for a chosen audience.
What Data·yze Readability Analyzer is
Data·yze Readability Analyzer estimates how readable text may be for a chosen audience. It reports six kinds of readability scores: Flesch-Kincaid Reading Ease, Gunning Fog Index, Kincaid Grade Level, SMOG, Dale–Chall, and Fry Reading Graph. Users can enter text or upload a file, then save or download the input. A paragraph view provides statistics and shows changes across a document; sentence analysis and clarity recommendations are also listed. For a webpage or broader site, the separate Website Readability Analyzer estimates readability for an individual page and the site average. Its crawler is capped at 1,000 pages per user per day; pausing and resuming on another day can work around that cap. The free web app is ad-supported. Data·yze says analyzed passages are not collected or stored, but passage length is retained for performance analysis. Writing-tool uploads are cached and automatically removed within seven days, possibly sooner. Third-party advertising and analytics services may use tracking cookies. The maker cautions that the metrics are heuristic estimates, not measures of writing quality, and work best with plain text.
