In their own words
A2Z Tools Plain Language Analyzer
A2Z Tools Plain Language Analyzer is a free web tool for checking English drafts against plain-language guidance. It links each finding to its source guideline and can flag complex words, GOV.UK words to avoid, hidden verbs, “shall” used for requirements, double negatives, passive voice, long sentences, and long words. A Flesch-Kincaid estimate compares the draft with an audience target. Defaults set thresholds for general-public text, service instructions, or professional readers, and users can add organization jargon with plainer alternatives using an equals sign. Findings can be exported as CSV. Text that is pasted, typed, or dropped is processed in the browser tab; the maker says it is not uploaded, logged, stored, or sent to analytics. The analyzer checks English only, combining US and UK word guidance. Scores measure sentence and word length rather than meaning, so findings are prompts for human review. It is free online at free.
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.
