In their own words
ApyHub Readability Scores Documents API
ApyHub Readability Scores Documents API scores documents and publicly accessible web pages, returning a readability score, reading level, and text statistics. File requests accept PDF, DOC, or DOCX uploads up to 100 MB. English checks use the Flesch Reading Ease formula by default, while German uses the Wiener Sachtextformel. Results can include word, sentence, character, and paragraph counts, average lengths, and estimated reading and speaking times. The score includes a grade class, a plain-language label, and an indication of whether a standard readability threshold is met. ApyHub lists uses such as reviewing contracts, policies, manuals, help pages, websites, reports, and proposals; AI agents can also access the API through ApyHub MCP for content reviews. The product page offers five API calls a day free without a card. Starter is free and includes 3,000 atoms per month; Pro costs $16 a month and Pro+ $42 a month. Requests can return a 429 rate_limited error when the plan's per-second limit is exceeded.
Data·yze Readability Analyzer
Data·yze Readability Analyzer is a free, ad-supported web app that estimates how readable text may be for a chosen audience. It reports Flesch-Kincaid Reading Ease, Gunning Fog Index, Kincaid Grade Level, SMOG, Dale–Chall, and Fry Reading Graph metrics. Sentence analysis and clarity recommendations are available, while a paragraph view shows statistics and changes in readability through a document. You can enter text or upload a file, then save or download the input. 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; pausing and resuming on another day can work around that cap. Data·yze says analyzed passages are not collected or stored, although passage length is retained for performance analysis. Uploaded files may be cached and automatically removed within seven days, possibly sooner. The maker cautions that scores are heuristic estimates, not writing-quality measures, and work best with plain text.
